2.2 INSTALLATION
After unpack the box, follow the steps below in order to properly connect the device. For better Wi-Fi performance,
put the device in a clearly visible spot, as obstacles such as walls and doors hinder the signal.
1. First, assemble router by attaching the necessary antennas and inserting the SIM card.
2. To power up router, please use the power adapter included in the box.
2.3 WIRING THE POWER INPUTS
Power Input port in the router provides 2 sets of power input connections (P1 and P2) on the terminal block. On the
picture below is the power connector.
Wiring the Power Input
1. Insert the positive and negative wires into the V+ and V- contact on the terminal block connector.
2. Tighten the wire-clamp screws to prevent the power wires from being loosened.
3. Connect the power wires to suitable DC Switching type power supply. The input DC voltage should be in the
range of 12VDC to DC 48V DC.
WARNING: Turn off DC power input source before connecting the Power to the terminal block
connectors, for safety purpose. Don not turn-on the source of DC power before all of the
connections were well established.
WARNING: Using a different power adapter can damage and void the warranty for this product

12
2.4 WIRING THE ALARM RELAY OUTPUT (DO)
The relay output contacts are located on the front panel of the router. The relay output consists of the 2-pin
terminal block connector that used to detect user-configured events. The two wires attached to the fault contacts
form a close circuit when a user-configured event is triggered. If a user-configured event does not occur, the fault
circuit remains open. The fault conditions such as power failure, Ethernet port link break or other pre-defined
events which can be configured in the device. Screw the DO wire tightly after digital output wire is connected.
2.5 CONNECTING THE GROUNDING SCREW
Grounding screw is located on the bottom side of the router. Grounding Screw helps limit the effects of noise due to
electromagnetic interference (EMI) such as lighting or surge protection. Run the ground connection from the ground
screw to the grounding surface prior to connecting devices. And tighten and wire to chassis grounding for better
durability.
NOTE: The relay contact only supports 1 A current, DC 24V. Do not apply voltage and current higher than
the specifications.

13
2.6 DIN RAIL MOUNTING
The EN50022 DIN-Rail plate should be already attached to the back panel of the device screwed tightly. If user needs
to reattach the DIN-Rail attachment plate to the device, make sure the plate is situated towards the top, as shown by
the following figures.
To mount the router on DIN Rail track, do the following instruction:
1. Insert the top side of DIN Rail track into the slot of DIN Rail clip.
2. Lightly clip the bottom of DIN-Rail to the track and make sure it attached well.
3. To remove the device from the track, reverse the steps.

14
2.7 ANTENNA
WR312G & WR322GR are supported with up to 5 antenna sockets, where 3G/LTE, GPS, and Wi-Fi antennas are
supported. All of the antennas are connected to the router by screwing all the antennas to the SMA connector on the
front panel of the router.

3. WEB MANAGEMENT CONFIGURATION
To access the management interface, WoMaster router has two ways access mode through a network; they are web
management and telnet management. Web interface management is the most common way and the easiest way to
manage a network, through web interface management, a router interface offering status information and a subset
of device commands through a standard web browser. If the network is down, another alternative to access the
management interface can be used. The alternative way is by using telnet management which is offer configuration
way through CLI Interface. This manual describes the procedures for Web Interface and how to configure and
monitor the managed router only.
PREPARATION FOR WEB INTERFACE MANAGEMENT
WoMaster provides Web interface management that allows user through standard web-browser such as Microsoft
Internet Explorer, or Mozilla, or Google Chrome, to access and configure the router management on the network.
1. Plug the DC power to the router and connect router to computer.
2. Make sure that the router default IP address is 192.168.10.1.
3. Check that PC has an IP address on the same subnet as the router. For example, the PC and the router
are on the same subnet if they both have addresses that start 192.168.10.x (Ex: 192.168.10.2). The subnet
mask is 255.255.255.0.
4. Open command prompt and ping 192.168.10.1 to verify that the router is reachable.
5. Launch the web browser (Internet Explorer or Mozilla Firefox or Google Chrome) on the PC.
6. Type http://192.168.10.1 (or the IP address of the router). And then press Enter and the login page will
appear.
7. Type user name and the password. Default user name: admin and password: admin. Then click Login.
In this Web management for Featured Configuration, user will see all of WoMaster Cellular Router’s various
configuration menus at the left side from the interface. Through this web management interface, user can configure,
monitoring, and set the administration functions. The whole information used web management interface to
