The data connection profile settings page is displayed. Figure 15 - Data connection profile settings
www.netcommwireless.com NetComm Wireless 4G M2M Router 25 v1.0 2. Click the Profile toggle key to turn the profile on. Additional settings appear. Figure 16 - Data connection settings - Profile turned on 3. In the Profile name field, enter a name for the profile. This name is only used to identify the profile on the router. 4. Ensure that the Automatic APN selection toggle key is set to off. If it is not, click it to toggle it to the off position. 5. In the APN field, enter the APN Name (Access Point Name) and if required, use the Username and Password fields to enter your login credentials. Note that the APN and username fields have a limit of 81 characters. 6. Next to Authentication type, select either CHAP or PAP depending on the type of authentication used by your provider. 7. The Reconnect delay field specifies the number of seconds to wait between connection attempts. The default setting of 30 seconds is sufficient in most cases but you may modify it to wait up to 65535 seconds if you wish. 8. The Reconnect retries field specifies the number of times to attempt a network connection if the router fails to establish a connection. It is set to 0 by default which causes the router to attempt to reconnect indefinitely. 9. The Metric value is used by router to prioritise routes (if multiple are available) and is set to 20 by default. This value is sufficient in most cases but you may modify it if you are aware of the effect your changes will have on the service. 10. The MTU field allows you to modify the Maximum Transmission Unit used on the connection. Do not change this unless instructed to by your carrier. 11. Use the NAT Masquerading toggle key to turn NAT Masquerading on or off. NAT masquerading, also known simply as NAT is a common routing feature which allows multiple LAN devices to appear as a single WAN IP via network address translation. In this mode, the router modifies network traffic sent and received to inform remote computers on the internet that packets originating from a machine behind the router actually originated from the WAN IP address of the router’s internal NAT IP address. This may be disabled if a framed route configuration is required and local devices require WAN IP addresses. 12. Click the Save button when you have finished entering the profile details.
26 NetComm Wireless 4G M2M Router www.netcommwireless.com v1.0 Confirming a successful connection After configuring the packet data session, and ensuring that it is enabled, click on the Status menu item at the top of the page to return to the Status page.

www.netcommwireless.com NetComm Wireless 4G M2M Router 27 v1.0 Connect on demand The Connect on demand feature keeps the Packet Data Protocol (PDP) context deactivated by default while making it appear to locally connected devices that the router has a permanent connection to the mobile broadband network. When a packet of interest arrives or an SMS wake-up command is received, the router attempts to establish a mobile broadband data connection. When the data connection is established, the router monitors traffic and terminates the link when it is idle. Note: When interesting packets arrive, the recovery time for the wireless WAN connection is approximately 20-30 seconds. Configuring Connect on demand To configure Connect on demand: 1. Click the Networking menu item from the top menu bar. 2. On the Connect on demand page, click the Connect on demand toggle key so that it is ON. Extra options appear. See the following sub-sections for further instructions. Figure 18 - Connect on demand configuration options
28 NetComm Wireless 4G M2M Router www.netcommwireless.com v1.0 Setting the router to dial a connection when traffic is detected on specific ports In some situations, you may wish to have the internet connection disabled except at times when outbound traffic to a particular external host’s port or group of ports is sent to the router. To use this feature, click Enable dial port filter and enter the port number or list of port numbers separated by commas. When you select this option, all outbound ICMP/TCP/UDP packets to any remote host on the specified port(s) will trigger the connection to dial. Note that when this feature is enabled, the options to ignore specific packet types are not available. Figure 19 – Connect on demand - Data activity triggered connection You can allow Microsoft network awareness (NCSI) traffic through but if you prefer that they do not trigger the connection, click the Ignore Microsoft network awareness (NCSI) traffic toggle key to set it to ON. Figure 20 - Connect on demand - Ignore NCSI traffic Excluding certain packet types from triggering the connection to dial Depending on your environment, you might prefer to exclude certain types of traffic passing through the router from triggering the data connection. You can tell the router to ignore outbound TCP, UDP or ICMP packets. When any of these options are checked the router will not dial a connection when that type of outbound destined data packet reaches the router from a locally connected device. Figure 21 – Connect on demand - Excluding IP protocols Excluding certain application types from triggering the connection to dial Some devices may generate general traffic as a part of normal operation which you may not want to trigger the data connection. You can set the router to ignore Domain Name System (DNS), Network Time Protocol (NTP) or Microsoft network awareness (NCSI) traffic from devices behind the router. When you check the box for these options, it tells the router to ignore the request from that application type and will not dial a connection when this data type is received. Figure 22 - Connect on demand - Excluding application types
www.netcommwireless.com NetComm Wireless 4G M2M Router 29 v1.0 Setting timers for connection and disconnection The router has a number of timer settings which let you determine when a connection is dialled and when it is disconnected. Figure 23 – Connect on demand - Connect and disconnect timers OPTION DESCRIPTION On data activity, stay online for at least When traffic as per the configured settings above appear, the router will either continue to stay online, or dial a connection and will not disconnect it for the specified time period (min. 1 minute, max. 1 hour). This timer is continuously reset throughout the duration of a dial-up session, whenever data activity is detected matching the rules above. After connecting, stay online for at least This timer configures the router to not hang-up the connection for the specified time period after initially dialing the connection. This setting cannot be less than the keep online period above. This timer affects the connection only once per dial up session, at the beginning of the session. After hanging up, don’t redial for After a connection has been disconnected, you can tell the router to rest for a period of time before re-dialing. Disconnect regardless of traffic after Forces the router to disconnect the connection regardless of the traffic passing through it. The default setting is never. Connect regularly, every / Randomize connect frequency by up to If you want to have the router dial a connection at regular intervals, use Connect regularly, every to specify the interval between dials. Setting this to never effectively disables this option. The router also features the ability to randomize the time at which the first dial action is performed. This is useful in situations such as where you have numerous routers in an area where a power outage has occurred. Setting a random dial time helps to reduce network congestion when all the routers are powered on so they do not all try to connect simultaneously. When Connect regularly, every is set to at least 2 minutes, you are able to configure the router to randomize the time it begins to dial. The randomized dial timer only affects the initial dial after the unit powers on or after the settings are saved. For example, if you configure the router to dial every 2 minutes with a randomized dial starting time of 1 minute, the router waits for the Connect regularly, every time (2 minutes) and then randomly selects a time less than or equal to the Randomize connect frequency by up to time (1 minute). After the randomly selected time has elapsed, the router dials the connection. After the first dial, the router dials the connection every 2 minutes, ignoring the Randomize connect frequency by up to time. Table 12 - Connect on demand - Connect and disconnect timers descriptions Verbose mode The router provides the option of logging all the data activity which matches the settings for the Connect on demand feature for advanced troubleshooting purposes. To enable the logging of the Connect on demand feature, click the Enable verbose mode toggle key to switch it ON. See the System log section for more information. Figure 24 – Connect on demand - Verbose logging configuration
30 NetComm Wireless 4G M2M Router www.netcommwireless.com v1.0 Manually connecting/disconnecting There may be times when you need to either force a connection to be made or force a disconnection manually. You can use the Manual connect and Manual disconnect buttons to do this whenever necessary. The online status of the connection is displayed above the buttons. Figure 25 - Connect on demand - Online/Offline control When you have finished configuring the options for the Connect on demand feature, click the Save button at the bottom to save your changes. SMS Wake up The router can also be woken up by means of an SMS message using the SMS diagnostics feature by sending an executable wakeup command via SMS. See the Diagnostics section for details on using the SMS Wake up function. SIM management The SIM management page displays the status of the SIM card. Figure 26 – SIM Management
www.netcommwireless.com NetComm Wireless 4G M2M Router 31 v1.0 Operator settings The Operator settings page enables you to select which frequency band you will use for your connection and enables you to scan for available network operators in your area. Figure 27 - Band settings Note: In order to change the operator’s band settings, the data connection must be disabled. When you access this page, you are prompted to disable the data connection if it is already active. You may want to do this if you’re using the router in a country with multiple frequency networks that may not all support High Speed Packet Access (HSPA). You can select the router to only connect on the network frequencies that suit your requirements. Use the Change band drop down list to select the band you wish to use. The following band settings options are available: Note: The available bands may vary depending on your variant of the product. It is not necessary to change the default setting of All bands in most cases. In fact, locking to a particular band can cause connection difficulties if the device is moved to a location where the forced band selection is no longer available. When All bands is selected, the router attempts to find the most suitable band based on the available networks for the inserted SIM card. The “2G all”, “WCDMA all”, “LTE all”, “3G/2G all” and “LTE/3G all” options allow you to force the device to lock to those particular networks only. Click the Save button to save and apply your selection. Operator settings The operator settings feature allows you perform a scan of available networks, and to optionally lock to a particular network returned by the network scan. To scan for available networks, set the Select operator mode from automatic to Manual then click the scan button. This operation can take a few minutes and requires that the packet data session be disconnected prior to scanning. Figure 28 - Operator settings
32 NetComm Wireless 4G M2M Router www.netcommwireless.com v1.0 A list of the detected cellular service carriers in your area is displayed. Figure 29 - Detected operator list Note: Certain module firmware versions may not allow forbidden operators to be selected. Select the most appropriate service from the list shown and click Apply. When Select operator mode is set to Automatic, the router selects the most appropriate operator based on the inserted SIM card. This is the default option and is sufficient for most users. SIM security settings The SIM security settings page can be used for authenticating SIM cards that have been configured with a security PIN. Unlocking a PIN locked SIM If the SIM card is locked, you will receive a notice when you access the Status page after which you will be directed to the PIN settings page to enter the PIN. The PIN settings page lists the status of the SIM at the top of the page.
www.netcommwireless.com NetComm Wireless 4G M2M Router 33 v1.0 If you are not redirected to the PIN settings page, to unlock the SIM: a) Click on the Networking menu from the top menu bar, and then click SIM security settings. Figure 30 - SIM security settings - SIM PIN locked b) Enter the PIN in the Current PIN field and then enter it again in the Confirm current PIN field to confirm the PIN. c) If you are placing the router in a remote, unattended location, you may wish to check the Remember PIN option. This feature allows the router to automatically send the PIN to the SIM each time the SIM asks for it (usually at power up). This enables the SIM to be PIN locked (to prevent unauthorised re-use of the SIM elsewhere), while still allowing the router to connect to the cellular service. When this feature is enabled, the PIN you enter when setting the Remember PIN feature is encrypted and stored locally on the router. The next time the SIM asks the router for the PIN, the router decrypts the PIN and automatically sends it to the SIM without user intervention. When this feature is disabled and the SIM is PIN locked and the PIN must be manually entered via the router‘s configuration interface. In situations where the router will be unattended, this is not desirable. Note: Select Remember PIN if you do not want to enter the PIN code each time the SIM is inserted. d) Click the Save button. If successful, the router displays the following screen: Figure 31 - SIM security settings - SIM unlock successful

36 NetComm Wireless 4G M2M Router www.netcommwireless.com v1.0 LAN LAN configuration The LAN configuration page is used to configure the LAN settings of the router and to enable or disable DNS Masquerading. To access the LAN configuration page, click on the Networking menu at the top of the screen, then click on the LAN menu on the left. Figure 36 – LAN configuration settings The default IP of the LAN port is 192.168.0.1 with subnet mask 255.255.255.0. To change the IP address or Subnet mask, enter the new IP Address and/or Subnet mask and click the Save button. Note: If you change the IP address, remember to reboot the router and enter the new IP address into your browser address bar. DNS masquerading DNS masquerading allows the router to proxy DNS requests from LAN clients to dynamically assigned DNS servers. When enabled, clients on the router’s LAN can then use the router as a DNS server without needing to know the dynamically assigned cellular network DNS servers. With DNS masquerading ON, the DHCP server embedded in the NTC-140-01 router hands out its own IP address (e.g. 192.168.0.1) as the DNS server address to LAN clients. The downstream clients then send DNS requests to the NTC-140-01 router which proxies them to the upstream DNS servers. With DNS masquerading OFF, the DHCP server hands out the upstream DNS server IP addresses to downstream clients directly, so that downstream clients send DNS requests directly to the upstream DNS servers without being proxied by the NTC-140-01 router. You may also override the DNS Masquerading option by specifying custom DNS Server IP addresses in the DHCP Server configuration mentioned in the next section of this guide. In this case the DHCP server assigns downstream devices the manually configured addresses and the DNS Masquerading option is ignored. In most cases, it is not necessary to disable DNS masquerading but if you need to, click the DNS masquerading toggle key to turn it OFF and then click the Save button.
www.netcommwireless.com NetComm Wireless 4G M2M Router 37 v1.0 DHCP The DHCP page is used to adjust the settings used by the router’s built in DHCP Server which assigns IP addresses to locally connected devices. To access the LAN configuration page, click on the Networking menu at the top of the screen, click on the LAN menu on the left then select the DHCP menu item. DHCP relay configuration In advanced networks configurations where the NTC-140-01 router should not be responsible for DHCP assignment, but instead an existing DHCP server is located on the Wireless WAN or LAN connections, the clients behind the NTC-140-01 router are able to communicate with the DHCP server when DHCP relay is enabled. This enables the NTC-140-01 router to accept client broadcast messages and to forward them onto another subnet. To configure the router to act as a DHCP relay agent click the DHCP relay toggle key to turn it ON and enter the DHCP server address into the DHCP server address field. DHCP relay is disabled by default. Figure 37 – DHCP relay configuration DHCP configuration You can manually set the start and end address range to be used to automatically assign addresses within, the lease time of the assigned address, the default domain name suffix, primary and secondary DNS server, the primary and secondary WINS server, as well as the advanced DHCP settings such as NTP, TFTP and Option 150/Option 160 (VoIP options).

42 NetComm Wireless 4G M2M Router www.netcommwireless.com v1.0 PPPoE If desired, you can have a client device connected to the Ethernet port initiate the mobile broadband connection using a PPPoE session. This is particularly useful in situations where you wish to provide Wireless WAN data access to an existing router which you want to have full public WAN IP access and have control over routing functionality. The PPPoE connection is established over the highest priority interface. To configure PPPoE: 1. Select the Networking menu item from the top menu bar, then select the PPPoE menu on the left side of the screen. The PPPoE configuration screen is displayed. Figure 43 - PPPoE configuration 2. Click the Enable PPPoE toggle key so that it is ON. 3. (Optional) In the Service name field, enter a name to use for the connection. This name is displayed on the Status page to identify the PPPoE connection. Any name you enter here must also be entered in the PPPoE connection profile in order for it to work. 4. If you require additional logging to be made available, click the Debug logging toggle key so that it is in the ON position. This displays PPPoE negotiation details in the System log. 5. The Forward WAN IP option determines whether the router passes the WAN IP address on to the PPPoE client. When this option is set to ON the first PPPoE client to connect will receive the WAN IP address and no further clients will be able to make a connection. In this mode, the router transparently bridges the connection and many of the router’s features are disabled. When this option is set to OFF, the router retains the WAN IP address and performs Network Address Translation (NAT) for connected clients. In this mode, you are able to connect multiple PPPoE clients and all of the router’s features are available. 6. Click the Save button to confirm the settings. 7. Click the Status menu item from the top menu bar. When Forward WAN IP is enabled, the status page shows a Transparent bridge mode section and displays the WAN IP. Figure 44 - Transparent bridge mode status 8. Configure the properties of the interface that the PPPoE connection will use (determined by WAN priority) in order to provide authentication credentials. Each interface uses the authentication credentials configured on the router for that particular interface, not those entered in the PPPoE client. For example, when using WWAN as the PPPoE interface, enter the username and password on the Data connection profile settings before connecting. See the Manually configuring a connection profile section for more detail. 9. Use your downstream device to initiate a network connection using a PPPoE client.
www.netcommwireless.com NetComm Wireless 4G M2M Router 43 v1.0 WAN failover The WAN failover page displays a summary of the configured WAN interfaces and their priorities (Metric). Lower metric values determine higher priority. The priority of the interfaces can be adjusted using the up and down arrows in the Priority column. When the interface with the highest priority goes down, the router fails over to the next highest priority interface. The method used to determine whether an interface is “up” or “down” is defined by the Monitor setting. By default, an interface is monitored by its link status. To access the WAN failover page, click on the Networking menu at the top of the screen then click on the WAN failover menu item on the left. Figure 45 - WAN summary To edit an interface, select the edit icon for the interface you wish to edit. The Failover configuration page is displayed. When Monitoring method is set to Hardware link the failover is controlled by the physical detection of the link. Figure 46 – Failover configuration – hardware link OPTION DESCRIPTION Priority The priority (metric) is a numeric value which determines which interface has priority. Lower priority values mean higher priority. Monitoring method Specifies the means used to determine whether the link is up or down. Verbose logging When enabled, this logs verbose comments in the system log related to the failover monitoring. Table 15 - Failover configuration - Hardware link monitoring When Monitoring method is set to Ping, the router sends periodic ping requests to the specified addresses to verify the connection is working. This works in a similar manner to the Watchdogs feature but with different ranges on the timers. Please refer to the Watchdogs section of this user guide for a more detailed description of this function.
44 NetComm Wireless 4G M2M Router www.netcommwireless.com v1.0 Figure 47 - Failover configuration - ping OPTION DESCRIPTION Priority The priority (metric) is a numeric value which determines which interface has priority. Lower priority values mean higher priority. Monitoring method Specifies the means used to determine whether the link is up or down. Verbose logging When enabled, this logs verbose comments in the system log related to the failover monitoring. First destination address The first address the router that the router should ping in order to confirm the connection is up. This may be an IP address or a domain name. Second destination address The second address the router that the router should ping in order to confirm the connection is up. This may be an IP address or a domain name. Periodic Ping timer The time in seconds between ping attempts. Retry timer The time in seconds between attempts when a ping failure occurs. Consecutive error monitor Fail count The number of failed pings that must occur before the monitor moves to the second destination address or fails the connection over to the next interface. Periodic ratio monitor Monitor total count This field specifies the number of previous pings to consider when calculating whether to fail over or fail back. Failover total count This field specifies the number of failed ping attempts with respect to the Monitor total count before the router fails over to the next highest priority interface. For example, at the default setting of 5, the router fails over to the next interface when 5 out of the last 10 ping attempts have failed. The failures need not be consecutive to meet the fail over criteria. If any 5 of the last 10 pings have failed, the router deems the interface connection to be of poor quality and fails over. Failback success count Like the Failover fail count field, this field specifies the number of ping successes that must be registered on a higher priority interface with respect to the Monitor total count before the router fails back to that interface. Table 16 - Failover configuration - Ping monitoring
www.netcommwireless.com NetComm Wireless 4G M2M Router 45 v1.0 Routing Static Static routing is the alternative to dynamic routing used in more complex network scenarios and is used to facilitate communication between devices on different networks. Static routing involves configuring the routers in your network with all the information necessary to allow the packets to be forwarded to the correct destination.

www.netcommwireless.com NetComm Wireless 4G M2M Router 47 v1.0 RIP RIP (Routing Information Protocol) is used for advertising routes to other routers. Thus all the routes in the router’s routing table will be advertised to other nearby routers. For example, the route for the router’s Ethernet subnet could be advertised to a router on the PPP interface side so that a router on this network will know how to route to a device on the router’s Ethernet subnet. Static routes must be added manually according to your requirements. See Adding Static Routes. To access the RIP configuration page, click on the Networking menu at the top of the screen, click on the Routing failover menu on the left, then click on the RIP menu item. Note: Some routers will ignore RIP. Figure 52 - RIP configuration To enable Routing Information Protocol (RIP) 1. Click the RIP toggle key to switch it to the ON position. 2.

48 NetComm Wireless 4G M2M Router www.netcommwireless.com v1.0 Redundancy (VRRP) configuration Virtual Router Redundancy Protocol (VRRP) is a non-proprietary redundancy protocol designed to increase the availability of the default gateway servicing hosts on the same subnet. This increased reliability is achieved by advertising a “virtual router” (an abstract representation of master and backup routers acting as a group) as a default gateway to the host(s) instead of one physical router. Two or more physical routers are then configured to stand for the virtual router, with only one doing the actual routing at any given time. If the current physical router that is routing the data on behalf of the virtual router fails, an arrangement is made for another physical router to automatically replace it. The physical router that is currently forwarding data on behalf of the virtual router is called the master router. Master routers have a priority of 255 and backup router(s) can have a priority between 1 and 254. A virtual router must use 00-00-5E-00-01-XX as its (MAC) address. The last byte of the address (XX) is the Virtual Router Identifier (VRID), which is different for each virtual router in the network. This address is used by only one physical router at a time, and is the only way that other physical routers can identify the master router within a virtual router. To access the Redundancy (VRRP) page, click on the Networking menu at the top of the screen, click on the Routing failover menu on the left, then click on the Redundancy (VRRP) menu item. Figure 53 - VRRP configuration To configure VRRP, configure multiple devices as follows and connect them all via an Ethernet network switch to downstream devices. 1. Click the Redundancy (VRRP) toggle key to activate VRRP. 2. In the Virtual ID field, enter an ID between 1 and 255. This is the VRRP ID which is different for each virtual router on the network. 3. In the Router priority field, enter a value for the priority – a higher value is a higher priority. 4. The Virtual IP address field is used to specify the VRRP IP address – this is the virtual IP address that both virtual routers share. 5. Click the Save button to save the new settings. Note: Configuring VRRP changes the MAC address of the Ethernet port and therefore if you want to resume with the web configuration you must use the new IP address (VRRP IP) or on a command prompt type: arp –d <ip address> (i.e. arp –d 192.168.1.1) to clear the arp cache.(old MAC address).
www.netcommwireless.com NetComm Wireless 4G M2M Router 49 v1.0 Port forwarding The Port forwarding list is used to configure the Network Address Translation (NAT) rules currently in effect on the router. To access the Port forwarding page, click on the Networking menu at the top of the screen, click on the Routing failover menu on the left, then click on the Port forwarding menu item. Figure 54 – Port forwarding list The purpose of the port forwarding feature is to allow mapping of inbound requests to a specific port on the WAN IP address to a device connected on the Ethernet interface. Adding a port forwarding rule To create a new port forwarding rule: 1. Click the +Add button. The port forwarding settings screen is displayed. 2. Use the Protocol drop down list to select the type of protocol you want to use for the rule. The protocols selections available are TCP, UDP and All. 3. In the Source IP Address field, enter a “friendly” address that is allowed to access the router or a wildcard IP address (0.0.0.0) that allows all IP addresses to access the router. 4. The Source Port Range (From) and (To) fields are used to specify the port(s) on the source side that are to be forwarded. This allows you to send a range of consecutive port numbers by entering the first in the range in the (From) field and the last in the range in the (To) field. To forward a single port, enter the port in the (From) field and repeat it in the (To) field. 5. In the Destination network address field, enter the IP address of the client to which the traffic should be forwarded. 6. The Destination Port Range (From) and (To) fields are used to specify the port(s) on the destination side that are to be forwarded. If the Source port range specifies a single port then the destination port may be configured to any port. If the Source port range specifies a range of port numbers then the Destination port range must be the same as the Source port range. 7. Click the Save button to confirm your settings. Figure 55 - Port forwarding settings To delete a port forwarding rule, click the button on the Port forwarding list for the corresponding rule that you would like to delete.
50 NetComm Wireless 4G M2M Router www.netcommwireless.com v1.0 DMZ The Demilitarized Zone (DMZ) allows you to configure all incoming traffic on all protocols to be forwarded to a selected device behind the router. This feature can be used to avoid complex port forwarding rules, but it exposes the device to untrusted networks as there is no filtering of what traffic is allowed and what is denied. The DMZ configuration page is used to specify the IP Address of the device to use as the DMZ host. To access the DMZ page, click on the Networking menu at the top of the screen, click on the Routing failover menu on the left, then click on the DMZ menu item. Figure 56 - DMZ configuration 1. Click the DMZ toggle key to turn the DMZ function ON. 2. Enter the IP Address of the device to be the DMZ host into the DMZ IP Address field. 3. Click the Save button to save your settings.
www.netcommwireless.com NetComm Wireless 4G M2M Router 51 v1.0 Router firewall The Router firewall page is used to enable or disable the in-built firewall on the router. When enabled, the firewall performs stateful packet inspection on inbound traffic from the wireless WAN and blocks all unknown services, that is, all services not listed on the Services configuration page of the router. With respect to the other Routing options on the Networking page, the firewall takes a low priority. The priority of the firewall can be described as: DMZ > MAC/IP/Port filtering rules > MAC/IP/Port filtering default rule > Router firewall rules In other words, the firewall is of the lowest priority when compared to other manual routing configurations. Therefore, a MAC/IP/Port filtering rule takes priority in the event that there is a conflict of rules. When DMZ is enabled, MAC/IP/Port filtering rules and the router firewall are ignored but the router will still honour the configuration of the Remote router access control settings listed under Administration Settings. To access the DMZ page, click on the Networking menu at the top of the screen, click on the Routing failover menu on the left, then click on the Router firewall menu item.

52 NetComm Wireless 4G M2M Router www.netcommwireless.com v1.0 MAC / IP / Port filtering The MAC/IP/Port filter feature allows you apply a policy to the traffic that passes through the router, both inbound and outbound, so that network access can be controlled. When the filter is enabled with a default rule of “Accepted”, all connections will be allowed except those listed in the “Current MAC / IP / Port filtering rules in effect” list. Conversely, when the default rule is set to “Dropped”, all connections are denied except for those listed in the filtering rules list. To access the MAC / IP / Port filtering page, click on the Networking menu at the top of the screen, click on the Routing failover menu on the left, then click on the MAC / IP / Port filtering menu item. Figure 58 - MAC / IP / Port filtering Note: When enabling MAC / IP / Port filtering and setting the default rule to “Dropped”, you should ensure that you have first added a filtering rule which allows at least one known MAC/IP to access the router, otherwise you will not be able to access the user interface of the router without resetting the router to factory default settings. Creating a MAC / IP / Port filtering rule To create a filtering rule: 1. Click the MAC / IP / Port filtering toggle key to switch it to the ON position. 2. Using the Default rule (inbound/forward) drop down list, select the default action for the router to take when traffic reaches it. By default, this is configured to Accepted. If you change this to Dropped, you should first configure a filter rule that allows at least one device access to the router, otherwise you will effectively be locked out of the router. 3. Click the Save button to confirm the default rule. 4. In the Current MAC / IP / Port filtering rules in system section, click the +Add button. Figure 59 - Current MAC / IP/ Port filtering rules in effect

Figure 60 - MAC / IP / Port filtering settings OPTION DESCRIPTION Bound Use the drop down list to select the direction of the traffic for which you want to apply to the rule. Inbound refers to all traffic that is entering the router including data entering from the WAN and the LAN. Outbound refers to all traffic exiting the router including traffic leaving in the direction of the WAN and traffic leaving in the direction of the LAN. Forward specifies traffic that enters on the LAN or WAN side and is forwarded to the opposite end. Protocol Use the drop down list to select the protocol for the rule. You can have the rule apply to All protocols, TCP, UDP, UDP/TCP or ICMP. Source MAC Address Enter the MAC address in six groups of two hexadecimal digits separated by colons (:). e.g. 00:40:F4:CE:FA:1E Source IP Address Enter the IPv4 address that the traffic originates from and the subnet mask using CIDR notation. Destination IP Address Enter the IPv4 address that the traffic is destined for and the subnet mask using CIDR notation. Action Select the action to take for traffic which meets the above criteria. You can choose to Accept or Drop packets. When the default rule is set to Accept, you cannot create a rule with an Accept action since the rule is redundant. Likewise, if the default rule is set to Dropped you cannot create a rule with a Drop action. Comment [Optional] Use this field to enter a comment as a meaningful description of the rule.

There are 5 authentication types you can choose from: CHAP – uses a three way handshake to authenticate the identity of a client. MS-CHAP v1 – This is the Microsoft implementation of the Challenge Handshake Authentication Protocol for which support was dropped in Windows® Vista. MS-CHAP v2 - This is the Microsoft implementation of the Challenge Handshake Authentication Protocol which was introduced in Windows® NT 4.0 and is still supported today. PAP – The Password Authentication Protocol uses a password as a means of authentication and as such, is commonly supported. PAP is not recommended because it transmits passwords unencrypted and is not secure. EAP – Extensible Authentication Protocol. An Authentication protocol commonly used in wireless networks. 8. The metric value helps the router to prioritise routes and must be a number between 0 and 65535. The default value is 30 and should not be modified unless you are aware of the effect your changes will have. 9. The Use peer DNS option allows you to select whether the remote clients will use the Domain Name Server of the PPTP server. Click the toggle key to set this to ON or OFF as required. 10. NAT masquerading allows the router to modify the packets sent and received to inform remote computers on the internet that packets originating from a machine behind the router actually originated from the WAN IP address of the router’s internal NAT IP address. Click the toggle key to switch this to the ON position if you want to use this feature. 11. Set default route to PPTP sets all outbound data packets to go out through the PPTP tunnel. Click the toggle key to switch this to the ON position if you want to use this feature. 12. The Verbose logging option sets the router to output detailed logs regarding the PPTP connection in the System Log section of the router interface. 13.

www.netcommwireless.com NetComm Wireless 4G M2M Router 69 v1.0 Data stream manager The data stream manager provides you with the ability to create mappings between two endpoints on the router. These endpoints may be physical or virtual, for example, a serial port connected to the router’s USB port could be configured as an endpoint or you could configure a TCP Server as an endpoint. You can then configure a virtual data tunnel or “stream” between the endpoints. The data stream manager provides a wide range of possibilities and expands upon simple PAD functionality to include the forwarding and translation of data between any of the endpoints. In each case, the logical flow of the stream is from Endpoint A to Endpoint B. Customers interested in developing their own applications to create custom endpoints and streams can contact NetComm Wireless about our Software Development Kit. Endpoints The first thing to be done in order to create a data stream is to define the endpoints. There are 6 types of endpoint that may be configured: Serial port (generic) TCP Server TCP Client UDP Server UDP Client User defined executable Circuit switched data (CSD) TCP connect-on-demand To access the Endpoints page, click on the Services menu at the top of the screen, click on the Data stream manager menu then click on the Endpoint menu item on the left. Figure 77 - Endpoints list
70 NetComm Wireless 4G M2M Router www.netcommwireless.com v1.0 Serial port (generic) This creates a generic serial port as an endpoint defaulting to the commonly used settings as shown below. Figure 78 - Serial port (generic) endpoint configuration (Custom) When the Host port is set to Custom, you can use the Custom host port name field to manually specify a device path to use, for example, if using a USB-to-Serial adapter you could telnet to the router and issue the command ls /dev/ttyUSB* to list the paths of the connected USB devices. To determine the path of the desired USB adapter, issue the command when the adapter is not connected then run the command again when the adapter is connected and compare the output. Note: Using a custom host port name is not recommended for normal use as the device path can change between power cycles of the router. TCP server This creates a TCP server endpoint with the following options available. Figure 79 - TCP server endpoint configuration
www.netcommwireless.com NetComm Wireless 4G M2M Router 71 v1.0 TCP client This creates a TCP client endpoint with the following options available. The retry timeout period specifies the number of seconds to wait between attempts to re-establish a connection in the event that it is lost. The client will attempt re-connection indefinitely every Retry timeout interval. Figure 80 - TCP client endpoint configuration UDP server This creates a UDP server endpoint with the following options available. Figure 81 - UDP server endpoint configuration UDP client This creates a UDP client endpoint with the following options available. The retry timeout period specifies the number of seconds to wait between attempts to re-establish a connection in the event that it is lost. The client will attempt re-connection indefinitely every Retry timeout interval. Figure 82 - UDP client endpoint configuration
72 NetComm Wireless 4G M2M Router www.netcommwireless.com v1.0 User defined executable Allows you to specify an executable and parameters to be used as an endpoint. For example, the following executable reads the phone module temperature every second. while true; do rdb_get wwan.0.radio.temperature; sleep 1; done The temperature can then be sent to another endpoint. Figure 83 – User defined executable endpoint configuration ITEM DESCRIPTION Host port Use the drop down list to select the serial port to use. If no USB-to-Ethernet adapter is connected, the only available selection is the Built-in serial port. Baud rate The serial (V.24) port baud rate. By default the serial line format is 8 data bits, No parity, 1 Stop bit. Refer to the AT (V.250) AT Command Manual if you need to change the serial line format. Data bits The default serial line data bits setting used is 8. Options include 5 – 8 bits. Stop bits The default stop bit setting is set to 1. However the stop bit setting can be set to 2 bits if required. Parity Parity is the means to detect transmission errors. An extra data bit is transmitted with each data character, and is arranged in a fashion such that the number of 1 bits in each character, including the parity bit, is always odd or always even. If a byte is received with the wrong number of 1s, then this shows the data must be corrupt. Options include none, odd or even. The default setting is none for no parity checks. Hardware flow control • Off - Serial port flow control off • Hardware - Serial port uses RTS/CTS flow control Software flow control Enables or disables software flow control. DSR action Sets the Data Set Ready action. This is an output from the modem and this configuration determines the pin’s behavior. • Always: DSR is always on. • Registered: When connected to a CSD endpoint, sets pin to “on” when modem is in data mode. • Session established: When connected to PPP endpoint, sets pin on when PDP is connected, when connected to IP modem endpoint, sets pin to on when modem is in online state (e.g. data connection is established). • Never: DSR is always off. • Mimic DTR: mimics the DTR pin. DCD action Determines how the router controls the state of the serial port Data Carrier Detect (DCD) line. • Always On: DCD is always on. • Connect: DCD is on when a connection is established in response to an ATD command or DTR dial. • Session established: Pin is on when PPP session is in progress or modem is in an online state (e.g. data connection is established). • Always Off: DCD is always off. DTR action Determines how the router responds to change of state of the serial port DTR line • Ignore - Take no action • Enter Command State – when connected to PPP endpoint, this is equivalent to disconnect. When connected to IP modem or CSD endpoint, this enters online command state (e.g. process AT commands without dropping the connection). • Disconnect – terminates connection. RI action Determines how the router controls the state of the serial port RI (Ring Indicator) line. • Always On: RI is always on. • Incoming Ring: RI is on when an incoming connection request is received. • Always Off: RI is always off Enable auto answer When enabled, the router accepts incoming connections. Circuit auto answer rings Sets the number of incoming rings after which the router will answer incoming circuit switched data calls. The default value is Off. The other available options are from 1 to 12. Advanced status Echo enable Enables echo on the serial side. All commands are echoes. This can be turned on/off via ATE1 and ATE0 commands. Recommended setting for this option is ON.
www.netcommwireless.com NetComm Wireless 4G M2M Router 73 v1.0 Quiet mode When on, there is no output from the modem on the serial side, i.e. you do not see OK, Connect etc. Recommended setting for this option is OFF. Send OK on carriage return If enabled, will print OK every time CR is received on the serial side. Recommended setting for this option is ON. Suppress line feeds If enabled, line termination is using CR (13). If disabled, line termination is CR LF (13 10). Recommended setting for this option is OFF. Send OK on unknown command Will send OK when an unknown/invalid AT command is received. Recommended setting for this option is ON. Verbose mode The modem returns messages to the computer to indicate the return status of commands and interrupts such as incoming call and call progress. Recommended setting for this option is ON. Table 19 - Modem emulator endpoint options Circuit switched data (CSD) The CSD (Circuit Switched Data) endpoint is designed for use when CSD connectivity is required between equipment connected through NetComm Wireless routers. A typical application of CSD is a dial-up connection to an ISDN service. CSD calls use the functionality of the GSM networking and switching subsystem to carry data via GSM or later cellular networks. In many ways, this is similar to making a voice call. When a CSD connection is established, the communication end points are connected via a virtual circuit, similar to connections on traditional phone network. Unlike other end points connected to a Modem emulator end point, CSD relies mainly on the functionality of 3G/4G/LTE module. In CSD mode, the data stream of the router transparently passes through the data and signals from the serial port to the module and vice-versa. The available data rates will vary according to the network of the service provider. It is not necessary to have PDP profiles enabled for this functionality, however, you may need a special SIM card with data functionality for CSD calls to be made. Check with your service provider. Figure 84 – Circuit switched data endpoint configuration
74 NetComm Wireless 4G M2M Router www.netcommwireless.com v1.0 ITEM DESCRIPTION Initialization method Default - when data stream is established, the module will be initialized to a well-known, safe configuration appropriate for CSD connection. These include the following AT commands: ATE1 - enable echo ATQ0 - disable quiet mode ATV1 - enable verbose mode AT&D2 - DTR line inactive disconnects the calls AT&S1 - DSR becomes active in data mode, and off in command mode AT&C1 - CD becomes active when call is connected Hardware flow control is enabled on the module User: no pre-defined commands are sent to the module. Custom initialization can be done using "Additional AT init commands" Additional AT initialization commands These commands are sent after default commands (if default method is used). For example, to change DTR operation to enter online command mode instead of default disconnect, use the following command: AT&D1 with "Default" initialization method. Inactivity timeout If a non-zero value is entered and the router detects an inactivity period in an established CSD call in excess of the number of minutes entered, the CSD call will be automatically terminated. Note: data sent in any direction will prevent the call from being disconnected. The specified value should be in minutes. Table 20 – CSD endpoint options TCP connect-on-demand endpoint The TCP connect-on-demand endpoint allows data to be buffered and then sent to a TCP server when the buffer has been filled. It is primarily useful in situations where you do not want ‘keep alive’ packets to keep the socket open and create an overhead when the TCP data connection is not in use. Figure 85 – TCP connect-on-demand endpoint configuration
www.netcommwireless.com NetComm Wireless 4G M2M Router 75 v1.0 ITEM DESCRIPTION Primary server IP address The IP address of the TCP server to which the router should attempt the initial connection. Port number The port number that the TCP server operates on. Backup server IP address If connection to the primary server fails, the router will attempt to connect to this address. Port number The port number that the backup TCP server operates on. Inactivity timeout The period, in seconds, that the socket is considered idle/inactive if no packets are sent. The timer begins at the end of the last sent packet. The valid range is 0-10000 seconds. If this field is set to 0, the client disconnects immediately after sending a packet. Minimum transmit buffer size The number of bytes that must be reached before the client decides to transmit. Start ID This is a string which, if configured, is sent before any serial data is sent, every time the client connects <START ID><SERIAL DATA> End ID This is a string which, if configured, is sent after all serial data, just before the client disconnects <START ID><SERIAL DATA><END ID> Keepalive Keepalive sends a message to check that the link is still active or to keep it active. Keepalive count The number of keepalive messages to send. Keepalive idle The duration between two keepalive transmissions when in idle condition. Keepalive interval The duration between two successive keepalive retransmissions. Table 21 – TCP connect-on-demand endpoint options To create an endpoint: 1. Click the +Add button on the right side of the page. A pop-up window appears. Figure 86 - Creating an endpoint 2. In the Endpoint name field, type a name for this endpoint. The name can contain alphanumeric characters only i.e. A-Z, a-z, 0-9. 3. Use the Endpoint types drop down list to select the type of endpoint to configure. 4. Click the OK button. The router displays a screen with configuration options for your chosen endpoint type. Enter the options for your endpoint as required. 5. Click the Save button. The Endpoints list is displayed with the newly created endpoint listed and a summary of the settings your configured. Figure 87 - Endpoints list
76 NetComm Wireless 4G M2M Router www.netcommwireless.com v1.0 Streams When you have created the required endpoints, you can then proceed to set up a data stream. A data stream sends data from one endpoint to another, performing any transformation of the data as required. When a stream is added, an underlying process on the router checks the validity of the stream, checking for conflicts and illogical configurations. To access the Streams page, click on the Services menu at the top of the screen, click on the Data stream manager menu then click on the Streams menu item on the left. Every stream requires two endpoints, Endpoint A and Endpoint B. In all cases, the flow of data is from Endpoint A to Endpoint B. To create a new stream: 1. Click the +Add button on the right side of the page. Figure 88 - Data stream list The Edit data stream page is displayed. 2. In the Data stream name field, enter a name for the Data stream. 3. Under Endpoint A, use the Endpoint name drop down list to select one of the endpoints you created previously. This endpoint should be the starting point of the stream. Use the Mode drop down list to select the mode of operation of the endpoint. The mode can be thought of as a transformation of the data as it leaves this endpoint. For example, if Endpoint A type is Serial port (generic), the Mode can be set to various Modbus server and client types. This means that upon arrival at Endpoint A, the data will be transformed into the chosen Modbus format, ready to be sent to Endpoint B. 4. Under Endpoint B, use the Endpoint name drop down list to select one of the endpoints you created previously. This endpoint should be the destination of the stream. The screenshot below shows a configuration sending data received on an attached serial port to a TCP server running on the router. Use the Mode drop down list to select the mode of operation of the endpoint. The mode can be thought of as a transformation of the data as it arrives at this endpoint. Figure 89 - Edit data stream Notes on data stream operation: • When any changes to the Data stream manager configuration are detected, all data streams are stopped and restarted as per the new configuration. • Multiple Modbus clients cannot connect simultaneously to Modbus serial slaves connected to the router.

78 NetComm Wireless 4G M2M Router www.netcommwireless.com v1.0 PADD PAD Daemon is a tool used to encapsulate raw serial data into a TCP packet to be transported over IP to another end point. The server receiving the TCP packets unpacks the data and the original raw serial data is passed out of its serial port to the attached device, thereby creating an invisible IP network to the two serial devices. The PAD Daemon runs as a background process which can be accessed via the web configuration interface. The PADD configuration page is located under “Services > PADD”. The PADD is used usually with multiple connections or when redundant connections are needed. The PADD has two modes: the PADD TCP/IP Server mode and PADD TCP/IP Client Mode. When PADD is enabled, both the PADD server mode and PADD client mode can be run at the same time. To access the PADD configuration page, click on the Services menu at the top of the screen then click on the PADD menu item on the left. Figure 91 - PADD
www.netcommwireless.com NetComm Wireless 4G M2M Router 79 v1.0 Remote management SNMP SNMP configuration The SNMP page is used to configure the SNMP features of the router. To access the SNMP configuration page, click on the Services menu at the top of the screen then click on the SNMP menu item on the left. Figure 92 - SNMP configuration SNMP (Simple Network Management Protocol) is used to remotely monitor the router for conditions that may warrant administrative attention. It can be used to retrieve information from the router such as the signal strength, the system time and the interface status. To configure SNMP: 1. Click the SNMP toggle key to switch it to the ON position. 2. Enter Read-only community name and Read-write community name which are used for client authentication. Community names are used as a type of security to prevent access to reading and/or writing to the routers configuration. It is recommended that you change the Community names to something other than the default settings when using this feature. 3. Click the Save button to save any changes to the settings. The Download button displays the Management Information Base (MIB) of the router. The MIB displays all the objects of the router that can have their values set or report their status. The MIB is formatted in the SNMP-related standard RFC1155.
80 NetComm Wireless 4G M2M Router www.netcommwireless.com v1.0 SNMP traps SNMP traps are messages from the router to the Network Management System sent as UDP packets. They are often used to notify the management system of any significant events such as whether the link is up or down. Configuring SNMP traps To configure SNMP traps: 1. In the Trap destination field, enter the IP address to which SNMP data is to be sent. 2. In the Heartbeat interval field, enter the number of seconds between SNMP heartbeats. 3. Use the Trap persistence field to specify the time in seconds that an SNMP trap persists. 4. Use the Trap retransmission time to specify the length of time in seconds between SNMP trap retransmissions. Figure 93 - SNMP traps To send a manual SNMP Heartbeat, click the Send heartbeat button. When you have finished configuring the SNMP traps, click the Save button to save the settings. Note: When a factory reset is performed via SNMP, the SNMP settings are preserved.
www.netcommwireless.com NetComm Wireless 4G M2M Router 81 v1.0 TR-069 To access the TR-069 configuration page, click the Services menu item, then select the TR-069 menu item on the left. Figure 94 - TR-069 configuration The TR-069 (Technical Report 069) protocol is a technical specification also known as CPE WAN Management Protocol (CWMP). It is a framework for remote management and auto-configuration of end-user devices such as customer-premises equipment (CPE) and Auto Configuration Servers (ACS). It is particularly efficient in applying configuration updates across networks to multiple CPEs. TR-069 uses a bi-directional SOAP/HTTP-based protocol based on the application layer protocol and provides several benefits for the maintenance of a field of CPEs: Simplifies the initial configuration of a device during installation Enables easy restoration of service after a factory reset or replacement of a faulty device Firmware and software version management Diagnostics and monitoring Note: • You must have your own compatible ACS infrastructure to use TR-069. In order to access and configure the TR-069 settings you must be logged into the router as the root user. • When a factory reset of the router is performed via TR-069, the TR-069 settings are preserved.
82 NetComm Wireless 4G M2M Router www.netcommwireless.com v1.0 The NetComm Wireless router sends “inform” messages periodically to alert the ACS server that it is ready. These inform messages can also be configured to accept a connection request from the ACS server. When a connection is established, any tasks queued on the ACS server are executed. These tasks may be value retrieval or changes and firmware upgrades. TR-069 configuration To configure TR-069: 1. Click the Enable TR-069 toggle key to switch it to the ON position. 2. In the ACS URL field, enter the Auto Configuration Server’s full domain name or IP address. 3. Use the ACS username field to specify the username used by the server to authenticate the CPE when it sends an “inform” message. 4. In the ACS password and Verify ACS password fields, enter the password used by the server to authenticate the CPE when it sends an “inform” message. 5. In the Connection Request Username field, enter the username that the CPE uses to authenticate the Auto Configuration Server during a connection request to the CPE. 6. In the Connection Request Password and Verify password fields, enter the password that the CPE uses to authenticate the Auto Configuration Server during a connection request to the CPE. 7. The inform message acts as a beacon to inform the ACS of the existence of the router. Click the Enable periodic ACS informs toggle key to turn on the periodic ACS inform messages. 8. In the Inform Period field, enter the number of seconds between the inform messages. 9. Click the Save button to save the settings.
www.netcommwireless.com NetComm Wireless 4G M2M Router 83 v1.0 OMA Lightweight M2M configuration Note: The OMA Lightweight M2M specification has not yet been finalised. As such, the current implementation of OMA-LWM2M is experimental and should not be deployed for regular use. We also do not recommend using OMA-LWM2M while the router is connected to an APN providing a publicly routable IP address. The OMA Lightweight M2M (OMA-LWM2M) protocol was designed by the Open Mobile Alliance to provide remote device management specifically for M2M devices. It is less taxing on the system and network than OMA-DM and TR-069. OMA-LWM2M runs over UDP and supports asynchronous notifications when a resource changes. It provides: Firmware upgrades Device monitoring and configuration Server provisioning Figure 95 - OMA Lightweight M2M configuration
84 NetComm Wireless 4G M2M Router www.netcommwireless.com v1.0 ITEM DESCRIPTION Enable LWM2M Toggles the OMA-LWM2M function on and off. Server URL The URL of the LWM2M server. This must begin with coap:// or coaps:// and include the server port number. The correct syntax for this field is coap://<server IP or domain name>:<port number>. The Server URL field performs validation on the entered address so the field must contain an address in the correct format. Listen port (normal) The port that the router listens on for LWM2M. Listen port (secure) When using DTLS (coaps), enter the port that the router listens on for secure connections. Security type (only used when Server URL starts with coaps://) NoSec – When selected, this uses DTLS with the NULL cipher, therefore, it provides no security. PSK – Pre-shared key mode. Keys are typically a string of text saved into a text file. We recommend creating a key at least 32 bytes in size to enhance your security. RPK – Raw Public Key. The key is an EC key in DER format. It must contain both public and private keys. When RPK is selected, the Client ID field is not used. You can generate a raw public key using commands such as: openssl ecparam -out 256.key -name secp256r1 –genkey openssl ec -in 256.key -outform der -out 256.der Client id (only used when Server URL starts with coaps:// and Security type is PSK) When server is a coaps:// address and security type is set to PSK, the Client id acts as a means of identifying the client, similar to a username. Client key (only used when Server URL starts with coaps:// and Security type is PSK or RPK) This field is used to upload the key file used when security type is set to PSK, delete the uploaded key file or show the currently stored key. Respond to any IP When turned on, this feature adds a firewall rule that allows the router to respond to any IP address on the designated port. This eases the restrictions that requests must come from servers the client is currently registered with. We recommend that this feature is turned off for normal use. Bootstrap When set to the ON position, this specifies that the Server URL field points to a bootstrap server. Read only When set to the ON position, this allows read only access to all LWM2M settings. Writing new values and executing commands are not permitted. When set to OFF, values may be read, written and executed. Table 23 – OMA Lightweight M2M configuration options Supported objects The objects and instances used by NetComm Wireless routers are all part of the Open Mobile Alliance and IPSO Alliance approved list. At this time, there are no NetComm-specific objects or instances. For more information on the Lightweight M2M specifications, please visit the Open Mobile Alliance Specifications for Public Comment website: http://technical.openmobilealliance.org/Technical/technical-information/specifications-for-public-comment Timeouts Most mobile networks use stateful firewalls or NAT where the timeout for UDP is approximately 1-2 minutes. If this applies to you, configure your server to change the 'lifetime' (resource 1/0/1) to be shorter than the default 86400. We suggest setting it to 60. Supported ciphers TLS_PSK_WITH_AES_128_CBC_SHA256 TLS_ECDHE_ECDSA_WITH_AES_128_CBC_SHA256 NULL (only if "NoSec" explicitly selected) Others may be negotiated by OpenSSL during connection
www.netcommwireless.com NetComm Wireless 4G M2M Router 85 v1.0 IO configuration The NTC-140-01 Router is equipped with a 2 x 2 Molex connector providing Power (+), Ground (−), a multipurpose input and output pin and an ignition detection input. The multipurpose input/output pin may be independently configured for various functions, including: NAMUR (EN 60947-5-6 / IEC 60947-5-6) compatible proximity sensor input Proximity sensor input for use with contact closure (open/closed) type of sensors (PIR sensors, door/window sensors for security applications) with the input tamper detection possible (four states detected: open, closed, short and break) by the use of external resistors Analogue 0V to 30V input Digital input (the I/O voltage measured by the Analogue input and the software making decision about the input state) with the threshold levels configurable in software Open collector output. Use the pull up voltage options to select the desired output voltage of the I/O pins. The pull up voltage you select will be the same for each pin when pull up is enabled for that pin. Each pin is capable of outputting either 3.3V or 8.2V. To access the IO configuration page, click the Services menu item, then select the IO configuration menu item on the left. Figure 96 – IO configuration options ITEM DESCRIPTION IO configuration IO Functionality Enables the configuration of the input and output pins on the 2x2 Molex connector. Pull up voltage Specifies the output voltage of the I/O pins. IO Manager Debug level Use the slide bar to adjust the level of detail you would like to see in the log for IO messages. A higher debug level displays more detailed messages in the log file. Per pin configuration Pin The I/O pin number corresponding to the pin on the Molex connector that you wish to configure. Mode The mode of operation for the corresponding pin. Available options are Digital input, Digital output, Analogue input, Namur input, Contact closure input. Pull up Use the pull up toggle keys to turn the pull up on or off for the corresponding pin. When turned on, the pull up voltage output is the value specified in the “Pull up voltage” option. Threshold Displays the current voltage threshold configured for the I/O pin. Value The value column displays whether the voltage detected on the line is low or high or allows you to configure the output value in the case that the pin is set to digital output. This can be useful for applications where monitoring of the transition between low and high is used to trigger an action. Table 24 - IO configuration options
86 NetComm Wireless 4G M2M Router www.netcommwireless.com v1.0 The table below describes the different modes available on the physical I/O pins of the router. MODE DESCRIPTION Digital input The corresponding pin accepts digital input. Pull up may be on or off and both 3.3V and 8.2V are available as pull up voltages. The value column displays whether the signal received on the pin is High or Low. Digital output The corresponding pin outputs a digital signal. Pull up may be on or off and both 3.3V and 8.2V are available as pull up voltages. The value column contains a toggle key allowing you to set whether the output signal is High or Low. Analogue input The corresponding pin accepts an analogue signal. Pull up may be on or off and both 3.3V and 8.2V are available as pull up voltages. The value column displays the current voltage detected on the pin. Namur input NAMUR is a sensor standard using low-level current signals. It can supply two different signal levels depending on the state of the switch and is commonly used in hazardous or explosive locations where compact sensors are required. When a pin is set to NAMUR mode, Pull up is turned on and the global Pull up voltage is set to 8.2V. These settings may not be changed for as long as a pin is set to NAMUR mode as they are required settings according to the NAMUR IEC 60947-5-6 standard. The value column displays whether the signal received on the pin is High or Low. Contact closure input A common type of digital input where a sensor or switch opens or closes a set of contacts as a result of a process change. An electrical signal is then used to determine whether the circuit is open or closed. When a pin is set to Contact closure input, Pull up is enabled for that pin and may not be turned off as long as the pin remains configured as a Contact closure input. Global pull up voltage may be either 3.3V or 8.2V. Table 25 - IO pin modes Note: Please refer to the SDK Developer Guide for hardware information about the Input/Output pins, wiring examples and configuration of the pins via the command line interface. There are also wiring examples in Appendix G of this User Guide. Contact NetComm Wireless Technical Support for access to the Software Development Kit.

92 NetComm Wireless 4G M2M Router www.netcommwireless.com v1.0 OPTION DEFINITION General SMS configuration SMS messaging Toggles the SMS functionality of the router on and off. Messages per page (10-50) The number of SMS messages to display per page. Must be a value between 10 and 50. Encoding scheme The encoding method used for outbound SMS messages. GSM 7-bit mode permits up to 160 characters per message but drops to 50 characters if the message includes special characters. UCS-2 mode allows the sending of Unicode characters and permits a message to be up to 50 characters in length. SMS forwarding configuration Forwarding Toggles the SMS forwarding function of the router on and off. Redirect to mobile Enter a mobile number as the destination for forwarded SMS messages. TCP server address Enter an IP address or domain name as the destination for forwarded SMS messages using TCP. TCP port The TCP port on which to connect to the remote destination. UDP server address Enter an IP address or domain name as the destination for forwarded SMS messages using UDP. UDP port The UDP port on which to connect to the remote destination. Table 29 - SMS Setup Settings SMS forwarding configuration Incoming text messages can be redirected to another mobile device and/or a TCP/UDP message server. Redirect to mobile You can forward incoming text messages to a different destination number. This destination number can be another mobile phone or a router phone number. For Example: If someone sends a text message and Redirect to mobile is set to “+61412345678”, the text message is stored on the router and forwarded to “+61412345678” at the same time. To disable redirection to a mobile, clear the Redirect to mobile field and click the Save button. Redirect to TCP / UDP server address You can also forward incoming text messages to a TCP/UDP based destination. The TCP or UDP server can be any kind of public or private server if the server accepts incoming text-based messages. The TCP/UDP address can be an IP address or domain name. The port number range is from 1 to 65535. Please refer to your TCP/UDP based SMS server configuration for which port to use. For Example: If someone sends a text message and TCP server address is set to “192.168.20.3” and TCP port is set to “2002”, this text message is stored in the router and forwarded to “192.168.20.3” on port “2002” at the same time. To disable redirection to a TCP or UDP address, clear the TCP server address and UDP server address fields and click the Save button.

www.netcommwireless.com NetComm Wireless 4G M2M Router 95 v1.0 Diagnostics The Diagnostics page is used to configure the SMS diagnostics and command execution configuration. This allows you to change the configuration, perform functions remotely and check on the status of the router via SMS commands. To access the Diagnostics page, click on the Services menu item then select the SMS menu on the left and finally select Diagnostics beneath it. Figure 104 - SMS diagnostics and command execution configuration SMS diagnostics and command execution configuration The options on this page are described below. Enable remote diagnostics and command execution Enables or disables the remote diagnostics feature. If this setting is enabled all incoming text messages are parsed and tested for remote diagnostics commands. If remote diagnostics commands are found, the router executes those commands. This feature is enabled by default. All remote diagnostic commands that are received are stored in the Inbox. Note: It is possible to adjust settings and prevent your router from functioning correctly using remote diagnostics. If this occurs, you will need to perform a factory reset in order to restore normal operation. We highly recommended that you use the white list and a password when utilising this feature to prevent unauthorised access. See the White list description for more information.
96 NetComm Wireless 4G M2M Router www.netcommwireless.com v1.0 Only accept authenticated SMS messages Enables or disables checking the sender’s phone number against the allowed sender white list for incoming diagnostics and command execution SMS messages. If authentication is enabled, the router will check if the sender’s number exists in the white list. If it exists, the router then checks the password (if configured) in the incoming message against the password in the white list for the corresponding sending number. If they match, the diagnostic or command is executed. If the number does not exist in the white list or the password does not match, the router does not execute the incoming diagnostic or command in the SMS message. This is enabled by default and it is strongly advised that you leave this feature enabled to maintain security. Send Set command acknowledgement replies The NTC-140-01 router will automatically reply to certain types of commands received, such as get commands, or execute commands. However acknowledgement replies from the NTC-140-01 router are optional with set commands and the Wakeup command. This option Enables or disables sending an acknowledgment message after execution of a set command or SMS Wakeup command. If disabled, the router does not send any acknowledgement after execution of a set command or SMS Wakeup command. All acknowledgment replies are stored in the Outbox after they have been sent. This can be useful to determine if a command was received and executed by the router. This option is disabled by default. Access advanced RDB variables By default, this option is turned off and only allows access to the basic RDB variables listed later in this guide. If this option is enabled, you are able to access the full list of RDB variables via SMS. Allow execution of advanced commands By default, this option is turned off and only allows execution of the basic commands listed later in this guide. If this option is enabled, you are able to execute advanced commands such as those which are common to the Linux command line. For example: “execute ls /usr/bin/sms*” to list the contents of the /etc folder on the router. Send acknowledgement replies to This option allows you to specify where to send acknowledgment messages after the execution of a set, get, or exec command. If a fixed number is selected, the acknowledgement message will be sent to the number defined in the Fixed number to send replies to field. If the sender’s number is selected, the acknowledgement message will be sent to the number that the SMS diagnostic or command message originated from. The default setting is to use the sender’s number. Fixed number to send replies to This field defines the destination number to which error messages are sent after the execution of a get, set, or exec command. This field is only displayed when Send Error SMS to is set to Fixed Number. Send command error replies Enables or disables the sending of an error message resulting from the execution of a get, set, or exec command. All error replies are stored in the Outbox after they have been sent. Send error replies to When Send Error SMS for Get/Set/Exec Command is set to ON, this option is used to specify where the error SMS is sent. Use the radio buttons to select either Fixed Number or SMS Sender Number. When set to SMS Sender Number the router will reply to the originating number of the SMS diagnostic or command. When set to Fixed Number the router will send the error messages to the number specified in the following field. Send a maximum number of You can set the maximum number of acknowledgement and error messages sent when an SMS diagnostic or command is executed. The maximum limit can be set per hour, day, week or month. The router will send a maximum of 100 replies by default. The number of messages sent is shown below the options. The total transmitted message count resets after a reboot or at the beginning of the time frame specified.
www.netcommwireless.com NetComm Wireless 4G M2M Router 97 v1.0 White List for diagnostic or execution SMS The white list is a list of mobile numbers that you can create which are considered “friendly” to the router. If Only accept authenticated SMS messages is enabled in the diagnostics section, the router will compare the mobile number of all incoming diagnostic and command messages against this white list to determine whether the diagnostic or command should be executed. You may optionally configure a password for each number to give an additional level of security. When a password is specified for a number, the SMS diagnostic or command message is parsed for the password and will only be executed if the number and password match. Figure 105 - White list for diagnostic or execution SMS A maximum of 20 numbers can be stored on the router in the white list. To add a number to the white list, click the “+Add” button. Figure 106 – Adding a number to the SMS white list The White List numbers and passwords can be cleared by pressing the button to the right of each entry. To add a number to the white list, enter it in the Destination number field and optionally define a password in the Password field. When you have finished adding numbers click the Save button to save the entries.
98 NetComm Wireless 4G M2M Router www.netcommwireless.com v1.0 Sending an SMS Diagnostic Command Follow the steps below to configure the router to optionally accept SMS diagnostic commands only from authenticated senders and learn how to send SMS diagnostic commands to the router. 1. Navigate to the Services > SMS messaging > Diagnostics page 2. Confirm that the Enable remote diagnostics and command execution toggle key is set to the ON position. If it is set to OFF click the toggle key to switch it to the ON position. 3. If you wish to have the router only accept commands from authenticated senders, ensure that Only accept authenticated SMS messages is set to the ON position. In the White list for diagnostic or execution SMS messages section, click the +Add button and enter the sender’s number in international format into the Destination number field that appears. If you wish to also configure a password, enter the password in the Password field corresponding to the destination number. 4. If you would prefer to accept SMS diagnostic commands from any sender, set the Only accept authenticated SMS messages toggle key to the OFF position. Note: An alternative method of adding a number to the white list is to send an SMS message to the router, navigate to Services > SMS messaging > Inbox and then click the button next to the message which corresponds to the sender’s number. 5. Click the Save button. Types of SMS diagnostic commands There are three types of commands that can be sent; execute, get and set. The basic syntax is as follows: execute COMMAND get VARIABLE set VARIABLE=VALUE If authentication is enabled, each command must be preceded by the password: PASSWORD execute COMMAND PASSWORD get VARIABLE PASSWORD set VARIABLE=VALUE The following are some examples of SMS diagnostic commands: password6657 execute reboot get rssi set apn1=testAPNvalue SMS acknowledgment replies The router automatically replies to get commands with a value and execute commands with either a success or error response. Set commands will only be responded to if the Send Set command acknowledgement replies toggle key is set to ON. If the Send command error replies toggle key is set to ON, the router will send a reply if the command is correct but a variable or value is incorrect, for example, due to misspelling.
www.netcommwireless.com NetComm Wireless 4G M2M Router 99 v1.0 SMS command format Generic Format for reading variables: get VARIABLE PASSWORD get VARIABLE Generic Format for writing to variables: set VARIABLE=VALUE PASSWORD set VARIABLE=VALUE Generic Format for executing a command: Execute COMMAND PASSWORD execute COMMAND Replies Upon receipt of a successfully formatted, authenticated (if required) command, the gateway will reply to the SMS in the following format: TYPE SMS CONTENTS NOTES get command “VARIABLE=VALUE” set command “Successfully set VARIABLE to VALUE” Only sent if the acknowledgment message function is enabled execute command “Successfully executed command COMMAND” Table 31 - SMS Diagnostic Command Syntax Where “VARIABLE” is the name of the value to be read Where “VARIABLE (x)” is the name of another value to be read Where “VALUE” is the content to be written to the “VARIABLE” Where “COMMAND” is a supported command to be executed by the device (e.g. reboot) Where “PASSWORD” is the password (if configured) for the corresponding sender number specified in the White List Multiple commands can be sent in the same message, if separated by a semicolon. For Example: get VARIABLE1; get VARIABLE2; get VARIABLE3 PASSWORD get VARIABLE1; get VARIABLE2 set VARIABLE=VALUE1 ; set VARIABLE2=VALUE2 PASSWORD set VARIABLE1=VALUE1; set VARIABLE2=VALUE2; set VARIABLE3=VALUE3 If required, values can also be bound by an apostrophe, double apostrophe or back tick. For Example: “set VARIABLE=’VALUE’” “set VARIABLE=”VALUE”” “set VARIABLE=`VALUE`” “get VARIABLE”
100 NetComm Wireless 4G M2M Router www.netcommwireless.com v1.0 A password (if required), only needs to be specified once per SMS, but can be prefixed to each command if desired. “PASSWORD get Variable1”; “get VARIABLE2” “PASSWORD set VARIABLE1=VALUE1”; “set VARIABLE2=VALUE2” If the command sent includes the “reboot” command and has already passed the white list password check, the device keeps this password and executes the remaining command line after the reboot with this same password. For Example: “PASSWORD execute reboot; getVariable1”; “get VARABLE2” “PASSWORD execute reboot; PASSWORD get Variable1”; “get VARABLE2” Note: Commands, variables and values are case sensitive. List of basic commands A list of basic commands which can be used in conjunction with the execute command are listed below: “pdpcycle”, “pdpdown” and “pdpup” commands can have a profile number suffix ‘x’ added. Without the suffix specified, the command operates against the default profile configured on the profile list page of the Web-UI. # COMMAND NAME DESCRIPTION 1 reboot Immediately performs a soft reboot. 2 pdpcycle Disconnects (if connected) and reconnects the data connection. If a profile number is selected in the command, try to disconnect/reconnect the specified profile in case the profile is active. If no profile number is selected, try to disconnect/reconnect the current active profile. Reports an error if no profile number is selected and there is no currently activated profile. 3 pdpdown Disconnects the PDP. If a profile number is selected in the command, the router tries to disconnect the specified profile in case the profile is active. If no profile number is selected, try to disconnect the current active profile. Reports an error if no profile number is selected and there is no currently activated profile. 4 pdpup Reconnects the PDP. If a profile number is selected in the command, the router tries to connect with the specified profile. If no profile number is selected, the router tries to connect to the last active profile. The gateway will check the currently activated profile and disconnect this profile before executing the command. The router reports an error if no profile number is selected and there is no stored last active profile number. 5 factorydefaults Performs a factory reset on the router. Be aware that this command also clears the SMS white list on the router. 6 download Performs a download and install of a Firmware Upgrade (.cdi), Config File (.tar.gz) or a help document (.pdf) file. If the file is a firmware image as in the case of a .cdi file, the router will apply the recovery image first and then the main firmware image. The download location is specified immediately after the command and may be from an HTTP or FTP source URL. If the file is a .cdi file, the router will apply the file as a configuration file update for the device and reboot afterwards. If the file is a .pdf, the router will assume this is a user guide document and save it to the router and make the file available for viewing via the help menu on the Web-UI. Note: If your download URL includes any space characters, please encode these prior to transmission according to RFC1738, for example: ftp://username:password@serveraddress/directory%20with%20spaces/filename.cdi Note: Authenticated FTP addresses may be used following the format as defined in RFC1738, for example: ftp://username:password@serveraddress/directory/filename.cdi 7 codconnect Causes the router to activate the PDP context when the Connect on demand feature is enabled. 8 coddisconnect Causes the router to de-activate the PDP context when the Connect on demand feature is enabled. 9 wakeup This forces the default Data connection profile to connect if it is in a disconnected or waiting state. There are two circumstances in which this command may be useful; where the default profile is enabled but has been manually disconnected and if Connect on demand is enabled and the router is awaiting packet of interest. In both of these situations, the wakeup command will cause the default PDP context to activate. 10 ssh.genkeys Instructs the router to generate new public SSH keys. 11 ssh.clearkeys Instructs the router to clear the client public SSH key files.

Table 36 - Operator status codes returned by get plmnscan SMS command Notes about the network connection status when using the get plmnscan command: • If the connection status is Up and connection mode is Always on, the get plmnscan SMS will cause the connection to disconnect, perform the scan, send the result through SMS and then bring the connection back up again. If the connection status is Down, the router will perform the PLMN scan, send the result and keep the connection status down. • If the connection status is Waiting and connection mode is Connect on demand, the get plmnscan SMS will change the connection status to Down, perform the scan, send the result through SMS and then restore the connection status to the Waiting state. • If the connection status is Up and connection mode is Connect on demand, the get plmnscan SMS will cause the connection to disconnect, perform the scan, send the result through SMS, and then restore the connection status to the Waiting state unless there is a traffic which triggers a connection in which case the connection status will be set to Up. Setting the router to connect to a network The router can be instructed by SMS to connect to one of the networks returned by the get plmnscan command. The set forceplmn command forces the router to connect to a specified operator network (if available) while the get forceplmn command retrieves the currently configured network on the router. Command format: set forceplmn=0|MCC,MNC| MCC,MNC,Network Type
104 NetComm Wireless 4G M2M Router www.netcommwireless.com v1.0 For example: set forceplmn=0 Sets the selection of operator and network type to automatic mode. set forceplmn=505,3 Sets the operator to a manual selection made by the user where “505” is the Mobile Country Code for Australia and “3” is the Mobile Network Code for Vodafone. As no network type (e.g. LTE/3G/2G) is specified, it is selected automatically. set forceplmn=505,3,7 Sets the operator and network type to a manual selection made by the user where “505” is the Mobile Country Code for Australia, “3” is the Mobile Network Code for Vodafone and “7” is the 3G network type. Notes about the set forceplmn command: 1. If the manual selection fails, the device will fall back to the previous ‘good’ network. 2. When enabled, the SMS acknowledgement reply reflects the success or failure of the manual selection with respect to the set command and includes the final MNC/MCC that was configured. Confirming the currently configured operator and network type You can retrieve the currently configured operator and network type using the get forceplmn command.

110 NetComm Wireless 4G M2M Router www.netcommwireless.com v1.0 System log settings To access the System log settings page, click on the System menu item then select the Log menu on the left and finally select System log settings beneath it. Log data is stored in RAM and therefore, when the unit loses power or is rebooted, it will lose any log information stored in RAM. To ensure that log information is accessible between reboots of the router there are two options: 1. Enable the Log to non-volatile memory option 2. Use a remote syslog server Figure 110 - System log settings Non-volatile log When the router is configured to log to non-volatile memory, the log data is stored in flash memory, making it accessible after a reboot of the router. Up to 512kb of log data will be stored before it is overwritten by new log data. Flash memory has a finite number of program-erase operations that it may perform to the blocks of memory. While this number of program-erase operations is quite large, we recommend that you do not enable this option for anything other than debugging to avoid excessive wear on the memory. Log capture level The log capture level defines the amount of detail that the system log stores. This setting also affects the Display level setting on the System log page, for example, if this is set to a low level, such as “Error”, the System log will not be able to display higher log levels. Remote syslog server The router can be configured to output log data to a remote syslog server. This is an application running on a remote computer which accepts and displays the log data. Most syslog servers can also save the log data to a file on the computer on which it is running allowing you to ensure that no log data is lost between reboots. To configure the NTC-140-01 router to output log data to a remote syslog server: 1. Click on the System menu from the top menu bar. The System log item is displayed. 2. Under the Remote syslog server section, enter the IP address or hostname of the syslog server in the IP / Hostname [PORT] field. You can also specify the port number after the IP or hostname by entering a semi-colon and then the port number e.g. 192.168.1.102:514. If you do not specify a port number, the router will use the default UDP port 514. 3. Click the Save button to save the configuration.

118 NetComm Wireless 4G M2M Router www.netcommwireless.com v1.0 Server certificate What is HTTP Secure? HTTP Secure or HTTPS is the use of the HTTP protocol over an SSL/TLS protocol. It is used primarily to protect against eavesdropping of communication between a web browser and the web site to which it is connected. This is especially important when you wish to have a secure connection over a public network such as the internet. HTTPS connections are secured through the use of certificates issued by trusted certificate authorities such as VeriSign. When a web browser makes a connection attempt to a secured web site, a digital certificate is sent to the browser so that it can verify the authenticity of the site using a built-in list of trusted certificate authorities. There are two main differences between how HTTPS and HTTP connections work: 1. HTTPS uses port 443 while HTTP uses port 80 by default. 2. Over an HTTPS connection, all data sent and received is encrypted with SSL while over an HTTP connection, all data is sent unencrypted. The encryption is achieved through the use of a pair of public and private keys on both sides of the connection. In cryptography, a key refers to a numerical value used by an algorithm to alter information (encrypt it), making the information secure and visible only to those who have the corresponding key to recover (decrypt) the information. The public key is used to encrypt information and can be distributed freely. The private key is used to decrypt information and must be secret by its owner. Each NTC-140-01 router contains a self-signed digital certificate which is identical on all NTC-140-01 routers. For a greater level of security, the router also supports generating your own unique key. Additionally, you may use third party software to generate your own self-signed digital certificate or purchase a signed certificate from a trusted certificate authority and then upload those certificates to the router. Generating your own self-signed certificate To generate your own self-signed certificate: 1. Click the System item from the top menu bar, then Administration from the side menu bar and then Server certificate. 2. Select a Server key size. A larger key size takes longer to generate but provides better security. 3. Click the Generate button to begin generating Diffie-Hellman parameters. 4. Enter the certificate details using the appropriate fields. Each field must be completed in order to generate a certificate. Figure 120 - Generate server certificate Note: The Country field must contain a code for the desired country from the list below.

www.netcommwireless.com NetComm Wireless 4G M2M Router 121 v1.0 SSH key management Secure Shell (SSH) is UNIX-based command interface and network protocol used to gain secure access to a remote computer, execute commands on a remote machine or to transfer files between machines. It was designed as a replacement for Telnet and other insecure remote shell protocols which send information, including passwords, as plain text. SSH uses RSA public key cryptography for both connection and authentication. Two common ways of using SSH are: Use automatically generated public-private key pairs to encrypt the network connection and then use password authentication to log on. Use a manually generated public-private key pair to perform the authentication and allow users or programs to log in without using a password. To access the SSH key management page, click on the System menu then the Administration menu on the left and then click on SSH key management. Figure 122 - SSH Server Configuration SSH Server Configuration To configure the SSH server settings: 1. Use the SSH Protocol drop down list to select the protocol that you want to use. Protocol 2 is more recent and is considered more secure. 2. Select the types of authentication you want to use by clicking the Enable password authentication and Enable key authentication toggle keys on or off. Note that you may have both authentication methods on but you may not turn them both off. 3. Click the Save button to confirm your settings.
122 NetComm Wireless 4G M2M Router www.netcommwireless.com v1.0 Host key management SSH keys provide a means of identification using public key cryptography and challenge response authentication. This means that a secure connection can be established without transmitting a password, thereby greatly reducing the threat of someone eavesdropping and guessing the correct credentials. SSH Keys always come in pairs with one being a public key and the other a private key. The public key may be shared with any server to which you want to connect. When a connection request is made, the server uses the public key to encrypt a challenge (a coded message) to which the correct response must be given. Only the private key can decrypt this challenge and produce the correct response. For this reason, the private key should not be shared with those who you do not wish to give authorization. The Host key management section displays the current public keys on the router and their date and timestamp. These public keys are provided in different formats, including DSA, RSA and ECDSA. Each format has advantages and disadvantages in terms of signature generation speed, validation speed and encryption/decryption speed. There are also compatibility concerns to consider with older clients when using ECDSA, for example. Generating new keys The complete set of keys can be re-generated by selecting the Generate keys button. This key generation process takes approximately 30 seconds to complete. Downloading keys The Get keys button allows you to download the complete set of public and private keys while the Get public keys button will download only the set of public keys. Uploading your own key files You can generate your own SSH keys and upload them to the router. To generate keys on a Linux-based machine, use the following commands: mkdir keys cd keys ssh-keygen -t rsa1 -f ssh_host_key -N "" ssh-keygen -t dsa -f ssh_host_dsa_key -N "" ssh-keygen -t rsa -f ssh_host_rsa_key -N "" ssh-keygen -t ecdsa -f ssh_host_ecdsa_key -N "" zip -e -P "PASSWORDHERE" -j keys.zip * Click the Upload keys button then locate the generated keys to upload them to the router.
www.netcommwireless.com NetComm Wireless 4G M2M Router 123 v1.0 Client key management The Client Key Management section is used for uploading the public key file of clients. To upload a client public key, click the Upload button, browse to the file and click Open. When the file is uploaded, it is examined for validity. If the key file is not a valid public key, it will not be uploaded. LED operation mode The 8 front LED indicators may be turned off after a timeout period for aesthetic or power saving reasons. To access the LED Operation Mode page, click the System menu, then Administration on the left and finally select LED Operation Mode. Figure 123 - LED Operation Mode The Mode drop down list sets the operation mode of the LEDs on the front panel of the router. To set the lights to operate at all times, set this to Always on. To set the lights to turn off after a specified period, select Turn off after timeout. When configured to turn off after timeout, use the LED power off timer field to specify the time in minutes to wait before turning off the LED indicators. The LED Power Off Timer must be an integer between 1 and 65535. The wait period begins from the time the Save button is clicked. When the wait period expires, the LEDs will turn off. If the router is rebooted, the LED power off timer is reset. The router will boot up and wait for the configured time before turning off again.
124 NetComm Wireless 4G M2M Router www.netcommwireless.com v1.0 Watchdogs To access the Watchdogs page, click the System menu item, then select the Watchdogs menu item on the left. Figure 124 - Watchdogs Settings Watchdogs are features which monitor the router for anomalies and restart the router if an anomaly occurs preventing its normal operation. When configured, the watchdogs feature transmits controlled ping packets to 1 or 2 user specified IP addresses to confirm an active connection. If the watchdog does not receive responses to the pings after a specified number of failures, it will reboot the device in a last resort attempt to restore connectivity. We recommend using caution when implementing this feature in situations where the device is intentionally offline for a particular reason, for example, when Connect-on-demand has been enabled. This is because the watchdog expects to be able to access the internet at all times, and will always eventually reboot the router if access isn't restored by the time the various timers expire and the fail count is reached. It is due to the nature of the watchdog being a last resort standalone backup mechanism that it will continue to do its job and reboot the device even when the Connect-on-demand session is idle, or the PDP context is disabled by the user. Therefore, we recommended that you disable this feature if Connect-on-demand is configured or if the PDP context is intentionally disconnected on occasion.
www.netcommwireless.com NetComm Wireless 4G M2M Router 125 v1.0 The watchdog works as follows: a) The router sends 3 consecutive pings to the first destination address at the interval specified in the Periodic Ping timer field. b) If all 3 pings to the first destination address fail, the router sends 3 consecutive pings to the second destination address at the Periodic Ping timer interval. c) If all 3 pings to the second destination address fail, the router sends 3 pings to the first destination address using the Periodic Ping accelerated timer interval. d) If all 3 accelerated pings to the first destination address fail, the router sends 3 pings to the second destination address at the Periodic Ping accelerated timer interval. e) If all 3 accelerated pings to the second destination address fail, the router registers this as a fail and returns to step C. f) When the number of failures reaches the number configured in the Fail count field, the router reboots. If any ping succeeds, the router returns to step A and does not reboot. Note: The Periodic Ping timer should not be set to a value of less than 300 seconds to allow the router time to reconnect to the cellular network following a reboot. To disable the periodic ping reset monitor, set Fail count to 0. Figure 125 – Ping watchdog settings
126 NetComm Wireless 4G M2M Router www.netcommwireless.com v1.0 Configuring Periodic Ping settings The Periodic Ping settings configure the router to transmit controlled ping packets to 2 specified IP addresses. If the router does not receive responses to the pings, the router will reboot. To configure the ping watchdog: 1. In the First destination address field, enter a website address or IP address to which the router should send the first round of ping requests. 2. In the Second destination address field, enter a website address or IP address to which the router should send the second round of ping requests. 3. In the Periodic Ping timer field, enter an integer between 300 and 65535 for the number of seconds the router should wait between ping attempts. Setting this to 0 disables the ping watchdog function. 4. In the Periodic Ping accelerated timer field, enter an integer between 60 and 65535 for the number of seconds the router should wait between accelerated ping attempts, i.e. pings to the second destination address. Setting this to 0 disables the ping watchdog function 5. In the Fail count field, enter an integer between 1 and 65535 for the number of times an accelerated ping should fail before the router reboots. Setting this to 0 disables the ping watchdog function. Disabling the Periodic Ping reset function To disable the Periodic Ping reset function, set Fail count to 0. Note: The traffic generated by the periodic ping feature is usually counted as chargeable data usage. Please keep this in mind when selecting how often to ping. Configuring a Periodic reboot The router can be configured to automatically reboot after a period of time specified in minutes. While this is not necessary, it does ensure that in the case of remote installations, the router will reboot if some anomaly occurs. 1. In the Force reboot every field, enter the time in minutes between forced reboots. The default value is 0 which disables the Periodic reboot function. The minimum period between reboots is 5 minutes while the maximum value is 65535 minutes. 2. If you have configured a forced reboot time, you can use the Randomise reboot time drop down list to select a random reboot timer. Randomising the reboot time is useful for preventing a large number of devices from rebooting simultaneously and flooding the network with connection attempts. When configured, the router waits for the configured Force reboot every time and then reboots after waiting for a random period that is less than or equal to the Randomise reboot time setting. 3. Click the Save button to save the settings. Note: The randomise reboot time is not persistent across reboots; each time the router is due to reboot, it randomly selects a time less than or equal to the Randomise reboot time.

136 NetComm Wireless 4G M2M Router www.netcommwireless.com v1.0 Appendix C: Recovery mode The NTC-140-01 Router features two independent operating systems, each with its own file systems. These two systems are referred to as 'Main' and 'Recovery'. It is always possible to use one in order to restore the other in the event that one system becomes damaged or corrupted (such as during a firmware upgrade failure). The recovery console provides limited functionality and is typically used to restore the main firmware image in the case of a problem. Accessing recovery mode Both systems have web interfaces that can be used to manipulate the other inactive system. The NTC-140-01 Router starts up by default in the Main system mode, however the router may be triggered to start in recovery mode if desired. To start the router in recovery mode: 1. Press and hold the physical reset button on the interface panel of the router for 5 to 15 seconds. When the LEDs on the front panel change to amber and countdown in a sequence, release the reset button. The router then boots into recovery mode. 2. In your browser, navigate to http://192.168.1.1. The router’s recovery mode is hardcoded to use this address regardless of the IP address that was configured in the main system. The router’s recovery console is displayed.

142 NetComm Wireless 4G M2M Router www.netcommwireless.com v1.0 Appendix G: Input/Output Overview The NTC-140-01 router is equipped with a 2 x 2 Molex connector providing a multipurpose input and output terminal as well as a dedicated ignition input. The I/O terminal may be independently configured for various functions, including: NAMUR (EN 60947-5-6 / IEC 60947-5-6) compatible sensor input Proximity sensor input for use with contact closure (open/closed) type of sensors (PIR sensors, door/window sensors for security applications) with the input tamper detection possible (four states detected: open, closed, short and break) by the use of external resistors Analogue 0V to 30V input Digital input (the I/O voltage measured by the Analogue input and the software making a decision about the input state) with the threshold levels configurable in software Open collector output. Hardware Interface The interface of the input/output terminals are based on the circuit diagram below The Input/Output label is the physical connection to the outside world. There are protection devices and resistor dividers to condition the signal prior to it going into the processor. The three labels to the right are the interface to the processor. Output Enable activates the Transistor which provides an open collector (ground) output and can sink 200mA at 230C. It is protected by a resettable fuse and transient protection diode. If used with the pull up resistor, which can be activated by the Pull up Voltage Enable pin, then you can have a High or Low output rather than open drain. The resistor can be pulled up to 3V3 for Cmos compatible output or 8.2V by software. The Analogue Input pin can read values from 0V to 30V. It is divided by a resistor network to read appropriate levels in the processor. Depending on the sensor type used, the pull up resistor can be switched on or off. If using the NAMUR sensor configuration the pull up will be activated to 8V2 by default.
www.netcommwireless.com NetComm Wireless 4G M2M Router 143 v1.0 Wiring Examples The following examples are shown as a guide as to what can be achieved by the I/O features. It is up to the system integrator to have enough knowledge about the interface to be able to achieve the required results. Note: NetComm Wireless does not offer any further advice on the external wiring requirements or wiring to particular sensors, and will not be responsible for any damage to the unit or any other device used in conjunction with it. Using outputs to control high voltage equipment can be dangerous. The integrator must be a qualified electrician if dealing with mains voltages controlled by this unit. Open Collector Output driving a relay Any output can be configured to control a relay. This is an example where the transistor will supply the ground terminal of the solenoid. External voltage is supplied to the other side of the solenoid. Logic level Output An output can be used with the pull up resistor to provide a logic level output which would be suitable to control an external digital device. LED Output An LED can be controlled by simply providing an open collector ground to an externally powered LED Resistor value and Voltage will need to suit the LED type used. Alternatively an LED can be powered using 8V2 via 1K resistor. The suitability of the LED will need to be investigated.
144 NetComm Wireless 4G M2M Router www.netcommwireless.com v1.0 Digital inputs There are several ways to connect a digital input. A digital input can be anything from a simple switch to a digital waveform or pulses. The unit will read the voltage in as an analogue input and the software will decode it in a certain way depending on your configuration. Below is a contact closure type input, which is detecting an Earth. Pull up is activated for this to work. The following input detects an input going high. The turn on/off threshold can be set in the software. NAMUR Sensor A NAMUR sensor is a range of sensors which conform to the EN 60947-5-6 / IEC 60947-5-6 standards. They basically have two states which are reflected by the amount of current running through a sense resistor.
www.netcommwireless.com NetComm Wireless 4G M2M Router 145 v1.0 Analogue Sensor with Voltage output There are various analogue sensors that connect directly to the unit which can provide a voltage output. These would require an external power source which may or may not be the same as the unit itself. The voltage range they provide can be between 0V and 30V. Some common sensor output ranges include 0V to 10V. The pull up resistor is not activated in this case. Analogue Sensor with 4 to 20mA output Another common type of sensor type is the 4-20mA current loop sensor. It provides a known current through a fixed resistor, usually 250 ohms thus producing a voltage of 0v to 5V at the input. The sensor would require an external power source which may or may not be the same as the unit itself. It will also require an external resistor. The internal pull up resistor is not activated. Analogue Sensor with Thermistor Some sensors work by changing resistance due to a change, such as temperature, light etc. These may be wired up to an external or internal power source and the resistance can be read into the analogue signal. This will require some software calibration like scaling or offset to map the voltage received to the sensor resistor value. An example below shows the internal pull-up voltage and 1K resistor activated. The voltage received depends on the combination of resistors and the value of the resistance of the sensor itself.
146 NetComm Wireless 4G M2M Router www.netcommwireless.com v1.0 System Example –Solar powered Router with battery backup The previous examples of wiring can be used to come up with a system. The following test case is an example of how the I/O’s can be used to enhance a simple router setup.
