CSA Class 1 Division 2 Option
CSA Class 1 Division 2 is Available Only on Specifically Marked Units
If marked this for Class 1 Division 2 – then this product is available for use in Class 1, Division 2,
in the indicated Groups on the product.
In such a case the following must be met:
The transceiver is not acceptable as a stand-alone unit for use in hazardous locations. The
transceiver must be mounted within a separate enclosure, which is suitable for the intended
application. Mounting the units within an approved enclosure that is certified for hazardous
locations, or is installed within guidelines in accordance with CSA rules and local electrical and
fire code, will ensure a safe and compliant installation.
Do not connect or disconnect equipment unless power has been switched off or the area is
known to be non-hazardous.
Installation, operation and maintenance of the transceiver should be in accordance with the
transceiver’s installation manual, and the National Electrical Code.
Tampering or replacement with non-factory components may adversely affect the safe use of
the transceiver in hazardous locations, and may void the approval.
The wall adapters supplied with your transceivers are NOT Class 1 Division 2 approved, and
therefore, power must be supplied to the units using the screw-type or locking type connectors
supplied from Microhard Systems Inc. and a Class 1 Division 2 power source within your panel.

2.0 Quick Start
This QUICK START guide will walk you through the setup and process required to access the
WebUI configuration window and to establish a basic wireless connection to your carrier.
Note that the units arrive from the factory with the Local Network setting configured as
‘Static’ (IP Address 192.168.168.1, Subnet Mask 255.255.255.0, and Gateway
192.168.168.1), in DHCP server mode. (This is for the LAN Ethernet Adapter on the back of
the VIP4G unit.
2.1 Installing the SIM Card
Before the VIP4G can be used on a cellular network a valid SIM Card for your Wireless
Carrier must be installed. Insert the SIM Card into the slot as shown below.
2.2 Getting Started with Cellular
Connect the Antenna’s to the applicable ANTENNA jack’s of the VIP4G.
Connect the power connector to the power adapter and apply power to the unit, once the
blue CPU LED is on solid, proceed to the next step.
SIM Card Slot
To reset to factory
defaults, press and hold
the CFG button for 8
seconds with the VIP4G
powered up. The LED’s
will flash quickly and the
IP4G will reboot with
factory defaults.
Use the MHS-supplied
power adapter or an
equivalent power source.

2.0 Quick Start
Connect A PC configured for DHCP directly to one of the LAN ETHERNET ports of the
VIP4G, using an Ethernet Cable. If the PC is configured for DHCP it will acquire a IP Ad-
dress from the VIP4G.
Open a Browser Window and enter the IP address 192.168.168.1 into the address bar.
The VIP4G will then ask for a Username and Password. Enter the factory defaults listed
below.
192.168.168.1
The factory default network
settings:
IP: 192.168.168.1
Subnet: 255.255.255.0
Gateway: 192.168.168.1
The Factory default login:
User name: admin
Password: admin
The factory default login:
User name: admin
Subnet: admin
It is always a good idea to
change the default admin
login for future security.
© Microhard Systems Inc. 15
Once successfully logged in, the System Summary page will be displayed.
As seen above under Carrier Status, the SIM card is installed, but an APN has not been
specified. Setting the APN to auto (default) may provide quick network connectivity, but
may not work with some carriers, or with private APN’s. To set or change the APN, click
on the Carrier > Settings tab and enter the APN supplied by your carrier in the APN field.
Some carriers may also require a Username and Password.
Once the APN and any other required information is entered to connect to your carrier,
click on “Submit”. Return to the System > Summary tab.
2.0 Quick Start
Auto APN: Introduced in
firmware version v1.1.6-
r1142, the VIP4G will attempt
to detect the carrier based on
the SIM card installed and
cycle through a list of
commonly used APN’s to
provide quick network
connectivity.
© Microhard Systems Inc. 16
On the Carrier > Status Tab, verify that a WAN IP Address has been assigned by your
carrier. It may take a few minutes, so try refreshing the page if the WAN IP Address
doesn’t show up right away. The Activity Status should also show “Connected”.
If you have set a static IP on your PC, you may need to add the DNS Servers shown in
the Carrier Status Menu to you PC to enable internet access.
Congratulations! Your VIP4G is successfully connected to your Cellular Carrier. The next
section gives a overview on enabling and setting up the WiFi Wireless features of the mo-
dem giving 802.11 devices network access.
To access devices connected to VIP4G remotely, one or more of the following must be
configured: IP-Passthrough, Port Forwarding, DMZ. Another option would be to set up a
VPN.
Ensure that all default passwords are changed to limit access to the mo-
dem. The admin password can be changed at the System > Access Con-
trol menu.
For best practices and to limit data charges it is critical to properly set
up the firewall. (Especially important for Public Static IP addresses.)
2.0 Quick Start
Ensure the default
passwords are changed.
Set up appropriate firewall
rules to block unwanted
incoming data.

2.3.2 Connecting to WiFi
Now that the VIP4G has connection to the Cellular Carrier (See Section 2.2) and the WiFI
has been set up (See Section 2.3), WiFi devices should be able to detect and connect to
the VIP4G.
On a WiFi enabled PC/Device, the SSID of MyNetwork, that was created in the last exam-
ple should be visible. Connect to that SSID and enter the password.
Once connected the status should change to connected, and network access should be
enabled.

4.1.5 System > Power Saving (Factory Installed Option)
The Power Saving feature of the VIP4G is only available in firmware version 1.1.6-1170 or later. It
also requires a factory installed modification that must be specified at the time of order, or returned
to the factory for an upgrade.
The Power Saving feature of the VIP4G works with the IGN line located on the PWR connector. It was
designed with vehicle systems in mind, but could be useful in other applications. The VIP4G must run for at
least 5 minutes before power saving will work.
The VIP4G requires that the IGN line be ON (1.8 - 32V) to boot up and perform normal operations. If the
IGN line goes OFF (Less than 1.8V) or floating (The Ignition of the vehicle turned OFF), the VIP4G will
then look at the Power Down Delay and start counting down to when it will turn itself off. It will also look at
the Power Down Voltage, if the voltage drops below the set value, the VIP4G will power down.
The VIP4G will power up and resume normal operation once the IGN line is retuned to the ON state.

4.2.4 Network > WIFI
Network WIFI Configuration
The WIFI menu is used to define (if required) a virtual interface in which to bind a WIFI connection. This
connection can then be bound to the Wireless Radio in the Wireless > Radio1 menu. If this interface is not
bound to the Wireless interface it has no operation or purpose.
The WIFI interface can be used setup a separate WIFI connection for connected devices (separating them
from the devices connected to the LAN), this would be the same as adding another interface under the
LAN configuration. In this mode the VIP4G would be operating as a Access Point (AP) providing network
access to any connected devices. A separate DHCP server must be defined if it is required to provide
DHCP services to connecting devices.
In most cases the WIFI interface would be setup to allow the VIP4G to operate as a Client to another
Access Point (AP). Using this menu it can be decided to use DHCP to obtain an IP address and related
networking information from the connected Access Point, or it could be setup with a static IP address that
is part of the AP’s network.
When connected as a Client the VIP4G would be able to use the WIFI network for data rather that the
cellular connection. However unless NetMotion or a static default route was set to manage this
connection there would be no way to predict which interface is used for data.

In port based VLAN port membership is exclusive, a port can only belong to a single VLAN, and is
generally used to separate the different subnets. In a port based VLAN every port should be a Untagged
Member, not a Tagged Member.
802.1Q VLAN uses tagging to allow separation of network segments. Ports can belong to multiple VLANs.
A Trunk port can be configured to communicate with other VLAN switch by adding all configured VLANs to
a single port. The native VLAN1 is used by default, it is important that any connected VLAN switch use the
same Native VLAN.

4.2.10 Network > SNMP
The VIP4G may be configured to operate as a Simple Network Management Protocol (SNMP) agent.
Network management is most important in larger networks, so as to be able to manage resources and
measure performance. SNMP may be used in several ways:
configure remote devices
monitor network performance
detect faults
audit network usage
detect authentication failures
A SNMP management system (a PC running SNMP management software) is required for this service to
operate. This system must have full access to the VIP4G. Communications is in the form of queries
(information requested by the management system) or traps (information initiated at, and provided by, the
SNMP agent in response to predefined events).
Objects specific to the VIP4G are hosted under private enterprise number 21703.
An object is a variable in the device and is defined by a Management Information Database (MIB). Both
the management system and the device have a copy of the MIB. The MIB in the management system
provides for identification and processing of the information sent by a device (either responses to queries
or device-sourced traps). The MIB in the device relates subroutine addresses to objects in order to read
data from, or write data to, variables in the device.
An SNMPv1 agent accepts commands to retrieve an object, retrieve the next object, set and object to a
specified value, send a value in response to a received command, and send a value in response to an
event (trap).
SNMPv2c adds to the above the ability to retrieve a large number of objects in response to a single
request.
SNMPv3 adds strong security features including encryption; a shared password key is utilized. Secure
device monitoring over the Internet is possible. In addition to the commands noted as supported above,
there is a command to synchronize with a remote management station.
The pages that follow describe the different fields required to set up SNMP on the VIP4G. MIBS may be
requested from Microhard Systems Inc.
The MIB file can be downloaded directly from the unit using the ‘Get MIB File’ button on the Network >
SNMP menu.

IP pass-through allows the 4G WAN IP address to be assigned to the device
connected to the physical LAN or WAN Port (DHCP or Static). In this mode the
VIP4G is for the most part transparent and forwards all traffic to the device
connected to the specified port except that listed below:
The WebUI port (Default Port:TCP 80), this port is retained for remote
management of the VIP4G. This port can be changed to a different port
under the System > Settings Menu.
The SNMP Listening Port (Default Port: UDP 161).

either do a ICMP or HTTP keep alive by attempting to reach a specified address at a regular interval. If the
VIP4G cannot reach the intended destination, it will reset the unit in an attempt to obtain a new connection
to the carrier. The Keepalive ensures that there is internet/network connectivity to the address specified at
all times. If the VIP4G does not have a SIM card installed, is not connected to the Carrier, or is on a
private APN, the default keepalive may not work and the unit will reboot at the interval configured.

When AP Isolation is enabled wireless devices connected to this SSID
will not be able to communicate with each other. In other words if the
VIP4G is being used as a Hot Spot for many wireless clients, AP
Isolation would provide security for those clients by not allowing
access to any other wireless device.

Image 4-4-6: Wireless > Netmotion
4.4.4 Wireless > Netmotion
Netmotion allows the modem to use the WIFI interface for a default data connection rather than the cellular
connection, when available. This is done by changing the default route between the Carrier and WIF
networks. When Netmotion is enabled the modem will attempt to use the WIFI connection as a WAN
connection for data first, and if that connection fails, or is not available, the modem will use the Cellular
connection. Up to 10 previously used networks can be used under Roaming for mobile applications.
For Netmotion to be used the modem must be configured to meet the following prerequisites.
- The Network > WIFI interface must be configured.
- The WIFI interface must be bound to Radio1 in the Wireless > Radio1 menu
- The Wireless interface must be setup as a Station/Client
When Netmotion is enabled, the Wireless interface cannot be used as a Access Point for other devices to
connect to.
Use this option to enable or disable the Netmotion functionality of the
modem.

The Roam menu is used in conjunction with Netmotion. When the modem is connected to a AP (Access
Point), the Roaming page will only display the currently connected network, and the History List of
previously used networks. If the modem is not currently connected to a Wireless Network, Roam will
display all available APs (Access Points) in range, as well as the history list of previously used networks.
The last 10 configured APs will be displayed in the list and will be automatically used if they are available.
This is ideal for mobile applications, where the modem will be moving from place to place. Unwanted
networks can be removed from the history list to prevent the modem from using it.

This menu option is used to configure the serial device server for the serial communications port. Serial
device data may be brought into the IP network through TCP, UDP, or multicast; it may also exit the VIP4G
network on another VIP4G serial port. The fully-featured RS232 interface supports hardware handshaking.
Basic configuration of the serial port would be to first, set the appropriate interface connection settings
such as the baud rate and data format. Next, it is critical to define the IP Protocol Config, since all serial
data entering the VIP4G is essentially converted to IP, to either TCP, or UDP packets. The following
section describes the configuration of the serial port.

This setting defines the serial output data framing. In Transparent
mode (default), the received data will be output promptly from the
VIP4G.
Date Mode
Values (selection)
Seamless / Transparent
When set to Seamless, the serial port server will add a gap between data frames to comply with the
MODBUS protocol for example. See ‘Character Timeout’ below for related information.
In Seamless mode (see Data Mode described on the preceding page),
this setting determines when the serial server will consider the recently
-received incoming data as being ready to transmit. As per the
MODBUS standard, frames will be marked as ‘bad’ if the time gap
between frames is greater than 1.5 characters, but less than the
Character Timeout value.
Character Timeout
Values (characters)
0
The serial server also uses this parameter to determine the time gap inserted between frames. It is
measured in ‘characters’ and related to baud rate.
Example: If the baud rate is 9600bps, it takes approximately 1ms to move one character. With the
Character Timeout set to 4, the timeout period is 4ms. When the calculated time is less than 3.5ms, the
serial server will set the character timeout to a minimum value of 3.5ms.
If the baud rate is greater than 19200bps, the minimum character timeout is internally set to 750us
(microseconds).
Defines the buffer size that the serial server will use to receive data
from the serial port. When the server detects that the Character
Timeout criteria has been met, or the buffer is full, it packetizes the
received frame and transmits it.

This setting determines which protocol the serial server will use to
transmit serial port data over the VIP4G network.
The protocol selected in the IP Protocol Config field will determine
which configuration options appear in the remainder of the COM1
Configuration Menu.
The serial port will not work unless the IP Protocol Config has been
configured properly. Once serial data is collected at the serial port, the
modem must be told how to deal with it, and where to send it.
IP Protocol Config
Values (selection)
TCP Client
TCP Server
TCP Client/Server
UDP Point-to-Point
SMTP Client
SMS Transparent Mode
GPS Transparent Mode
The protocol selected in the
IP Protocol Config field will
determine which configuration
options appear in the
remainder of the COM1
Configuration Menu.
TCP Client: When TCP Client is selected and data is received on its serial port, the VIP4G takes the
initiative to find and connect to a remote TCP server. The TCP session is terminated by this same unit
when the data exchange session is completed and the connection timeout has expired. If a TCP
connection cannot be established, the serial port data is discarded.
Remote Server Address
IP address of a TCP server which is ready to accept serial port data through a TCP
connection. For example, this server may reside on a LAN network server.
Default: 0.0.0.0
Remote Server Port
A TCP port which the remote server listens to, awaiting a session connection request from
the TCP Client. Once the session is established, the serial port data is communicated from
the Client to the Server.
Default: 20001
Outgoing Connection Timeout
This parameter determines when the VIP4G will terminate the TCP connection if the
connection is in an idle state (i.e. no data traffic on the serial port).
Default: 60 (seconds)
TCP Server: In this mode, the VIP4G Series will not INITIATE a session, rather, it will wait for a Client to
request a session of it (it’s being the Server—it ‘serves’ a Client). The unit will ‘listen’ on a specific TCP
port. If a session is established, data will flow from the Client to the Server, and, if present, from the Server
to the Client. If a session is not established, both Client-side serial data, and Server-side serial data , if
present, will be discarded.
Local Listening Port
The TCP port which the Server listens to. It allows a TCP connection to be created by a TCP
Client to carry serial port data.
Default: 20001
Incoming Connection Timeout
Established when the TCP Server will terminate the TCP connection is the connection is in
an idle state.
Default: 300 (seconds)
UDP: User Datagram
Protocol does not provide
sequencing information for
the packets sent nor does it
establish a
’connection’ (‘handshaking’)
and is therefore most suited
to communicating small
packets of data.
TCP: Transmission Control
Protocol in contrast to UDP
does provide sequencing
information and is connection
-oriented; a more reliable
protocol, particularly when
large amounts of data are
being communicated.
Requires more bandwidth
than UDP.

TCP Client/Server: In this mode, the VIP4G will be a combined TCP Client and Server, meaning that it
can both initiate and serve TCP connection (session) requests. Refer to the TCP Client and TCP Server
descriptions and settings described previously as all information, combined, is applicable to this mode.
UDP Point-to-Point: In this configuration the VIP4G will send serial data to a specifically-defined point,
using UDP packets. This same VIP4G will accept UDP packets from that same point.
Remote IP Address
IP address of distant device to which UDP packets are sent when data received at serial port.
Default: 0.0.0.0
Remote Port
UDP port of distant device mentioned above.
Default: 20001
Listening Port
UDP port which the IP Series listens to (monitors). UDP packets received on this port are
forwarded to the unit’s serial port.
Default: 20001
SMTP Client: If the VIP4G has Internet access, this protocol may be used to send the data received on
the serial port (COM1), in a selectable format (see Transfer Mode (below)), to an e-mail addressee. Both
the SMTP Server and the e-mail addressee must be ‘reachable’ for his feature to function.
Mail Subject
Enter a suitable ‘e-mail subject’ (e-mail heading).
Default: COM1 Message
Mail Server (IP/Name)
IP address or ‘Name’ of SMTP (Mail) Server.
Default: 0.0.0.0
Mail Recipient
A valid e-mail address for the intended addressee, entered in the proper format.
Default: host@
Message Max Size
Maximum size for the e-mail message.
Default: 1024
Timeout (s)
How long the unit will wait to gather data from the serial port before sending an e-mail
message; data will be sent immediately upon reaching Message Max Size.
Default: 10
Transfer Mode
Select how the data received on COM1 is to be sent to the email addressee. Options
are: Text, Attached File, Hex Code.
Default: Text
A UDP or TCP port is an
application end-point. The IP
address identifies the device
and, as an extension of the IP
address, the port essentially
‘fine tunes’ where the data is
to go ‘within the device’.
Be careful to select a port
number that is not
predetermined to be
associated with another
application type, e.g. HTTP
uses port 80.
