IP1 is used to build a virtual LAN with the front-end device (i.e. the Webcam), and it has to be in the same IP range as the front-end device’s IP, for example, 192.168.1.*. Figure Appendix 2-4: Configure Loopback adapter’s IP address Press “OK” after configuration, the software will set the IP address to the Loopback adapter. 3) Find the device to be tested based on IMEI, click "Add" to add user PC to the virtual LAN of "Customer Device - ER-800 - User PC", then the user PC can communicate directly with the customer device. Figure Appendix 2-5: Add Virhub PC to virtual LAN 5. Access the wireless router remotely via Virhub ER-800 V1.0.6 or higher version has functionality of accessing the wireless router remotely via Virhub. Normally, the router dials up into the wireless network and gets an inner IP address, and it cannot be accessed from the internet via this inner IP. eTung’s Virhub solution can solve the problem. First, enable Virhub function on the router, and set a remote access IP; the
ER-800 User Manual 40 remote access IP is dedicated to access the router remotely when Virhub is enabled on the router. Then run Virhub software on the far-end PC, and configure an IP address on the Loopback adapter; this IP must be in the same range as the remote access IP on the router. This way, we can access the router remotely on the far-end PC via the remote access IP, to perform configuration, system monitoring, etc. Below are the details about the configuration procedure. 1) Configure the router’s remote access IP According to “2. Configure Virhub Parameters”, go to the router’s Virhub configuration, enable Virhub and configure username, then there are two parameters: “Remote Access IP” and “Remote Access Mask”, with default values: 192.168.168.1 and 255.255.255.0. Figure Appendix 2-6: Configure the router’s remote access IP Normally set the two parameters with default values, and they can also be changed on demand. Press “Save” after configuration, then reboot the router. These two parameters can also be changed/checked via remote AT commands, please refer “2.5 Remote Configurations”. 2) Configure the Loopback adapter’s IP address to access the router remotely Run Virhub software, click button “Configure”, and on the popped up “Settings” dialog, set the Loopback adapter’s IP address in “Loopback Adapter IP Settings” part. IP2 is the IP address set on the Loopback adapter to access the router remotely via Virhub, and this IP must be in the same range as the “Remote Access IP” (192.168.168.1 by default) set on the router in step 1), for example, 192.168.168.*.
ER-800 User Manual 41 Figure Appendix 2-7: Configure the Loopback adapter’s IP address to access the router remotely Click “OK” after configuration is complete, the software will then set the IP address on the Loopback adapter. 3) Access the router remotely Open browser, and input the router’s remote access IP (192.168.168.1 by default), and then the router’s web configuration page shows. Figure Appendix 2-8: Access the router’s Web configuration page remotely Then we can login the web page to change the router’s parameters remotely, just as the router is directly connected locally.
ER-800 User Manual 42 Appendix 3: APN Network Testing Case APN is the abbreviation of Access Point Name. It is used in operators’ core network to identify the external data network, for example, enterprise intranet, Internet, WAP website and enterprise’ internal networks. Using the APN SIM card, the terminal dials up into a dedicated network predefined from the operator side, and normally gets an internal IP address to access the network, this IP address cannot be accessed from the internet. But the terminals that dial into the same dedicated network can access each other. So we can easily implement the interconnection between wireless terminals with operator’s APN networks, it’s very convenient and can greatly reduce network access cost. There are two kinds of solutions to use APN networks, and below are details for each of them. Solution 1: Embedded Data Center with APN Network eTung’s wireless routers support APN SIM card, and has embedded data center function. For those small-scale projects with few terminals, use one router as the data center, and dial into APN network; at the same time, all other terminals that connect to devices at the far end dial into the same APN network, then from the router’s data center we can access the terminals at the far end, thus implement remote control of devices at the far end. This solution is cost-efficient, and can be easily deployed; it’s flexible and convenient, and can be used especially in small-scale (No. of terminals <=100) device control projects. Figure Appendix 3-1: Embedded data center and APN network solution Below we will illustrate how to deploy this solution, and use MD-609G as an
ER-800 User Manual 43 example for terminals at the far end. First of all, please order APN SIM cards from operator, and parameters include APN name, PPP username and password, and for the SIM card used by the router there should be a static IP address assigned as well. 1. Configure APN parameters in the router According to the description of “2.1 Configurations”, login in the configuration web page, Choose “Wireless Net”->”Simple Cfg”, and then select “Manual Set” for APN Mode, configure APN name, and PPP username and password if required. click “Save” and then reboot the router to apply the change. Figure Appendix 3-2: Configure APN parameters in the router 2. Configure Embedded Data Center in the router Login the router’s configuration web page, choose “DTU Function”->”Embedded DC”, enable embedded DC, set transport protocol as TCP, center port as 9000, and set the maximum number of terminals as required, at most 100, and then click “Save” and reboot the router.
ER-800 User Manual 44 Figure Appendix 3-3: Configure embedded DC in the router After the router reboots and dials up into the APN network, in configuration web page “Status”, we can check the IP address assigned by APN network. Figure Appendix 3-4: Check the IP address acquired from APN network 3. Configure data center address and APN parameters in DTU Run wireless configuration software dtucfg.exe, power on DTU according to the prompt and then enter the configuration menu. For the 1st item: mServer DN/IP Addr, set as the static IP address acquired by the router from APN network, for example, 10.8.224.81; for the 2nd item: mServer Port, set as 9000; for the 4th item: APN, set as the APN name; for the 5th item: Protocol, set as TCP that is the same as the transport protocol configured in the embedded data center; then press Enter until Dial Account and Password, set as PPP username and password of the APN SIM card as required.
ER-800 User Manual 45 Figure Appendix 3-5: Configure DC address and APN parameters in DTU After that press Enter until the serial port parameters: baud rate, data bits, parity, stop bits and flow control, the values for these parameters must be the same as those set in the serial device that DTU connects to; and if they are not the same, we can modify the values here in DTU to make sure they are the same.
ER-800 User Manual 46 Figure Appendix 3-6: Configure DTU serial port parameters After configuration is finished, reboot DTU to dial up into APN network, it will then automatically connect to the router’s embedded data center; in the router’s status page, we can see that one device has connected the embedded data center. Figure Appendix 3-7: Status shows DTU has connected to embedded DC 4. Device at the front end receives/sends data via serial port
ER-800 User Manual 47 After configuring router and DTU at the far end, both dial up into the APN network, and DTU connects to the embedded data center running in the router; then we can receive data from the serial device at the far end via the router’s user serial port, and at the same time device at the front end can send data to the device at the far end via the router’s user serial port. Pay attention, the front-end device broadcast data to all the far-end devices, so there should be identity in the data packets sent/received between front-end and far-end devices to distinguish from/to whom the packets are received/sent. Solution 2: mServer Connects the Router and with APN Network For large-scale projects with lots of terminals, this solution: mServer connects the router and with APN network can be used. As shown in the figure below, eTung’s wireless router dials into operator’s APN network, and the data center at the back end connects to the router with Ethernet cable; at the same time configure DMZ host on the router, then terminals at the far end dial into the same APN network and can connect to the data center at the back end. Compared to solution 1, this solution can also be easily deployed and cost-efficient; at the same time since the data center is running in a dedicated server, compared to embedded data center solution, it allows more terminals to connect to the data center, and there can be more flexible configurations, for example, map a virtual serial port for each terminal, make point-to-point mapping between two terminals, etc. Figure Appendix 3-8: mServer connects to the router and with APN network Below we will illustrate how to deploy this solution, and use MD-609G as an example for terminals at the far end. First of all, please order APN SIM cards from operator, and parameters include APN name, PPP username and password, and for the SIM card used by the router there should be a static IP address assigned as well. 1. Install and run mServer in the data center server Ask eTung for mServer installer, and install mServer according the user manual. Make sure the firewall software allows accessing mServer from outside.
ER-800 User Manual 48 After mServer is installed, double-click mServer’s icon on the desktop to run mServer console, choose “System Settings”, in tab “Service Settings”, choose TCP for link mode, and set listen port as 9000. Figure Appendix 3-9: Configure mServer 2. Configure APN parameters in the router As step 1 in solution one shows, configure APN parameters in the router’s configuration web page. 3. Configure DMZ host in the router First, connect data center server to the router with Ethernet cable. Then, set static IP address in the data center server, and the IP address must be in the same IP range as the IP address of the router’s Ethernet interface, for example, 192.168.1.*. The figure below shows the server’s static IP address is set to 192,168.1.100, and gateway and DNS are set to 192.168.1.1.
ER-800 User Manual 49 Figure Appendix 3-10: Set static IP address Login the router’s web configuration page, choose “NAT Rule”->”DMZ Host”, then configure DMZ Host IP as the static IP address of the data center server, for example, 192.168.1.100 as configured above.
ER-800 User Manual 50 Figure Appendix 3-11: Configure DMZ host Click “Save”, and then reboot the router. Then data packets received by the router from the outside network will be forwarded to the data center server. 4. Configure data center address and APN parameters in DTU Configure data center address and APN parameters as shown in step 3 of solution one. Set data center IP address to the IP address acquired by the router after dialing into the network, and data center port as mServer’s listening port, i.e. 9000 as shown in figure appendix 5-9. After configuration is complete, reboot DTU, it will dial into APN network, and then connect to mServer; in mServer’s console we can see that this terminal is already online. Figure Appendix 3-12: DTU is online in mServer’s console
ER-800 User Manual 51 After DTU connects to the data center, the application software at the front end will then be able to communicate with the devices at the far end via virtual serial port (or other ways).
ER-800 User Manual 52 Appendix 4: Use ER-800 to Access LAN Remotely via VPN ER-800 can be used to extend and access the corporate virtual LAN remotely with VPN function, for example, the user can use ER-800 to dial into corporate LAN. But the router in user's corporate LAN should support VPN in this way. We will illustrate below how to implement this kind of network connection with VPN. 1. System Architecture Figure Appendix 4-1: Use ER-800 to access LAN remotely via VPN 2. Preparations 1) One router with VPN function(use PPTP protocol as an example), a LAN is attached to this router and can access internet; 2) One ER-800(including accessories) 3) One USIM card with internet service(for example China Unicom wo) 4) One PC 3. Steps 1) Configure to use PPTP when accessing the router Here we use router RV042 from Linksys as an example. First, this router supports VPN and PPTP protocol. Login this Linksys router. and click "VPN"->"PPTP", enable PPTP server and set the IP range for VPN connection, then create username and password used for VPN connection, as shown in the figure below:
ER-800 User Manual 53 Figure Appendix 4-2: Configure router's VPN function Actually different routers have different configuration interface and options, we can configure it accordingly. 2) Configure ER-800 Login ER-800's configuration interface, click "VPN function" and configure it as shown in the figure below: Figure Appendix 4-3: Configure account for VPN function
ER-800 User Manual 54 Type -- PPTP or L2TP VPN server IP or domain -- the IP address on corporate LAN side, if the IP address is not static, we recommend to apply a domain free of charge from Oray or Gnway, then input the domain here, ER-800 supports domain resolving. Username -- the username configured in the router at corporate LAN side, i.e. the username configured in Linksys router before; Password -- the password configured in the router at corporate LAN side, i.e. the password configured in Linksys router before; VPN function -- ON, to enable VPN connection. After all settings are complete, reboot ER-800. 3) Check dialing status Login ER-800 to check dialing status, as shown in the figure below: Figure Appendix 4-4: ER-800 status of accessing LAN At this time, ER-800 is connected to the corporate LAN, and visiting http://192.168.0.207 inside the corporate LAN can see ER-800's web login interface, and at the same time ER-800 can access resources inside the corporate LAN. If we connect a video server to ER-800, and configure port forwarding or DMZ host on ER-800, we can then access http://192.168.0.207 inside the
ER-800 User Manual 55 corporate LAN and then access the video monitoring interface. Notes: 1） The IP address used by PC or video server that is connected to ER-800 must not be in the same range as those IP addresses at the corporate LAN side. For example, if the IP range at the corporate LAN side is 192.168.0.*, then ER-800 should be in other IP range, for example 192.168.1.*. 2） ER-800 and the PC or video server that connects to it should be in the same IP range. ER-800's default gateway is 192.168.1.1, and if the IP range of the PC or video server that connects to ER-800 need to be 192.168.0.*, then change ER-800's gateway to the same range, for example 192.168.0.1.
ER-800 User Manual 56 Appendix 5: Send/Receive SMS with the Router and SMS Format ER-800 supports sending/receiving SMSs via Ethernet interface. The method is described below: First, establish a TCP connection with the router’s Ethernet IP (192.168.1.1 by default) and port: 8888; then use command AT+SMS or AT+SMSA to send SMSs. For example, use TCP Test Tool to send SMS as shown below: Figure Appendix 5-1: Send SMS via router’s Ethernet interface 1) In the left part “Client”, input router’s Ethernet IP address “192.168.1.1” in “IP Address/Name”, and router’s listening port “8888” in “Port”, then click
ER-800 User Manual 57 “Connect” to establish TCP connection with the router; if “Connected” is shown Connection Status, that means TCP Test Tool has connected to the router’s listening port. 2) Input AT+SMS or AT+SMSA command in box “Edit/Send Data”, and pay attention to end with CR, then click “send”; if “OK” is shown in box “Edit/Data Log”, that means the command has been sent successfully. NOTE: 1) Currently only ER-800 v1.0.3 or higher version supports sending/receiving SMSs via Ethernet interface. 2) Currently receiving long SMSs is supported, but sending long SMSs is not supported, i.e. the length of messages in English cannot exceed 160 characters, and the length of messages in Chinese cannot exceed 70 words. 3) AT commands must end with CR (0x0d), expressed below as “\r”. 1. Using AT command to send short messages 1) Special AT command for sending short messages with ASCII encoding via serial port： AT+SMSA=<target number>,<data length>,<data>\r DTU will send the following reply: \r\nOK\r\n Or: \r\nERROR\r\n Target Number: Phone number to receive the short message Data Length: The actual data length behind Data: The data to be sent, MUST with ASCII encoding. Examples: Send “1234” with ASCII encoding to 13812345678: AT+SMSA=13812345678,4,1234\r 2) General AT command for sending short messages via serial port： AT+SMS=<target number>,<encoding format>,<data length>,<data>\r DTU will send the following reply: \r\nOK\r\n Or: \r\nERROR\r\n Target Number:Phone number to receive the short message Encoding Format: 1:ASCII encoding, 2:8bit encoding, 3:Unicode encoding Data Length: The actual data length behind Data: The data to be sent, each byte should be formatted to a 2-byte hexadecimal number, for instance “1234” should be written as“31323334”. Examples: Send “1234” with ASCII encoding to 13812345678: AT+SMS=13812345678,1,4,31323334\r
ER-800 User Manual 58 Use 8bit encoding to send “1234”to 13812345678: AT+SMS=13812345678,2,4,31323334\r Use Unicode encoding to send “你好” to 13812345678: AT+SMS=13812345678,3,4,4F60597D\r 2. The received SMS messages will be output via the serial port in the format below: \r\n+SMS:<phone number>,<encoding format>,<data length>,<data>\r\n Examples: “1234” received from 13812345678 in ASCII format: \r\n+SMS:13812345678,1,4,31323334\r\n “1234” received from 13812345678 in 8bit encoding: \r\n+SMS:13812345678,2,4,31323334\r\n “你好” received from 13812345678 in Unicode encoding: \r\n+SMS:13812345678,3,4,4F60597D\r\n If the received SMS has more than one message, the format is as below: \r\n+SMSL:<identifier>,<total>,<sequence number>,<phone number>,<encoding format>,<data length>,<data>\r\n The messages with the same identifier can be assembled into one long SMS. For example, a long SMS is received from 10001, with identifier 05000376, total 4 messages, and below is the fourth message: \r\n+SMSL:05000376,4,4,10001,3,6,007600793002
