•Current: 160-260mA, 12V DC (depending on cellular module version)
•Consumption: 1.9W (during 2G/3G communication), 3.1W (during 4G LTE or
LTE Cat.M communication)
The IP51 immunity protection will be effective only in case of under normal usage
and operation conditions with unharmed hardware conditions by using the device
in the provided enclosure/chassis.
Deliberate damage or occing casualty of the device means the loss of product
warranty.
To ensure general safety, please follow the following guideline:
■ Keep the chassis area clear and dust-free during and after installation.
■ Do not wear loose clothing that could get caught in the chassis. Fasten your tie or scarf
and roll up your sleeves.
■ Do not perform any action that creates a hazard to people or makes the equipment
unsafe.
Safety with Electricity
Follow this guideline when working on equipment powered by electricity.
■ Read all the warnings in Safety Warnings.
■ Locate the emergency power-off switch for your installation location. If an electrical
accident occurs, you can quickly turn off the power.
■ Disconnect all power before:
–Installing or removing a chassis
–Working near power supplies
–Insertion a SIM card or change the SIM

■Look carefully for possible hazards in your work area, such as moist floors, ungrounded
power extension cables, frayed power cords, and missing safety grounds.
■ Do not work alone if hazardous conditions exist.
■ Never assume that power is disconnected from a circuit. Always check.
■ Never open the enclosure of the router’s internal power supply.
■ If an electrical accident occurs, proceed as follows:
–Use caution; do not become a victim yourself.
–Turn off power to the device.
–If possible, send another person to get medical aid. Otherwise, assess the victim’s
condition and then call for help.
–Determine if the person needs rescue breathing or external cardiac compressions;
then take appropriate action.
Preventing Electrostatic Discharge Damage
Electrostatic discharge (ESD) can damage equipment and impair electrical circuitry. It
may occur if electronic printed circuit cards are improperly handled and may cause
complete or intermittent failures. Always follow ESD prevention procedures when
removing and replacing modules:
■ Ensure that the router chassis is electrically connected to earth ground.
■ Wear an ESD-preventive wrist strap, ensuring that it makes good skin contact.
Connect the clip to an unpainted surface of the chassis frame to channel unwanted ESD
voltages safely to ground. To guard against ESD damage and shocks, the wrist strap and
cord must operate effectively.
■ If no wrist strap is available, ground yourself by touching a metal part of the chassis.
Mounting, fastening
The edge of the bopla aluminum enclosure of the device can be fixed by optionally with
an AB800MKL fixation part to a DIN-rail. You can also mount the enclosure to wall, place
into server rack or similar fixation opportunity.

The device enclosure can be fixed by the AB-MKL (left) one-sided DIN-rail adapter,
or by the AB800MKL adapter (right) to a wall or DIN-rail (accessories can be ordered)

1.5 Antenna
Please note that close metal parts, the cabinet metal
material and the industrial conditions as the usage of high
rate power or other external gained radio frequency signals
can cause radio signal disturbance and could cause weak
wireless signal at reception or data transmitting or could
cause less effective signal reception, weak wireless fidelity. In
any of these cases, we recommend you to test the wireless
signal reception and quality. If it is necessary use
external, magnetic mount antenna which is leaded
outside of the cabinet and placed onto the cabinet’s
surface –to ensure enough reception.
You can use an external magnatic mount antenna is
you want.
In case of poor signal quality at problematic installation
places you can use directional antenna or directional
MIMO antenna.

cable is removed from the POWER titled microfit connector (1) –or the adapter is
not connecting to the power network.
2. Mount a proper LTE antenna to the MAIN (left) SMA connector (7).

3. Insert an activated SIM card to the SIM slot (2) - the SIM chip surface must be
look to top and the cutted edge of the SIM must be look to the router –then push
the SIM until it will be fixed and closed (you will hear a soft click sound).
(In case of necessary of SIM removal you have to power off the router and push
the SIM a bit, while it will be released and can be removed).
4. Connect an UTP cable to the router’s Ethernet titled RJ45 port (6). During the
configuration the cable’s opposite connector must be connected to the PC’s
Ethernet port. (After the configuration connect it to the network- or industrial
device’s RJ45 port.)
5. You can also configure the router through the micro-USB slot (4) by a microUSB-
USB cable of the PC connection.
6. Connect the RS485 meter to the RS485 port (10) to receive the data of the external
device or meter. (In case of RS485 / Modbus version connect the external device
to the port nr. 12, for RS232 version connect the external device to the port nr. 11).
1.8 First start
The router is provided with pre-installed system (which contains the operating firmware
and the OpenWrt®system, which is accessible on the local website of the router).

1. Connect the microfit connection power connector (1) when the router begins its
operation, where the LED lights will be signing and inform you about the current
status of the device.
2. When starting the device (at power on) –or in case of rebooting –all the three
LEDs of the router will active for a few seconds.
LED1
LED2

4. The system start requires about 1-2 minutes, while the device loads the necessary
modules or the operation and prepares the web configuration user interface –the
LED2 will sign it. Then the web interface will be availble for login.
5. Configure the device’s wireless internet module settings (SIM and APN data on
the router web interface) for the cellular internet connection –otherwise the
router will be restarting in ever 10 minutes.
6. The modem registration to the cellular network is signed by the LED3 flashing
after the settings. If it was succesful (to register the SIM card data to the network)
then the LED2 will lighting, which shows that the router can access the cellular
network already.

devices.
•Check the RS485 settings (Ser2net).

5. Then the router’s local web interface will be loaded and you can login.
•Username: root
•Password: wmrpwd
6. Push to the Login button.
Attention!
Don’t forget to change the login password before connecting the router to the
public cellular network!

1.10 Access via SSH connection
The router can be accessed through ssh connection also, when it is available on its IP
address –use the putty terminal utility/tool for the connection
1. Connect to the 192.168.10.1:22 IP address.
(Login: root, Password: wmrpwd)
2. Accept the security risk (RSA token) encryption key usage warning notice (visible
at first time only).
Then the Linux command line will appear, where you can use standard Uc Linux kernel
4.9 compatible commands and execute scripts on the device.
You can also use UCI command line interface commands here. The UCI®(Unified
Configuration Interface) is an OpenWrt®API utility that allows centralized configuration
and management of the OpenWrt®operation system, configuration of the router.

To review the UCI commands and options that can be used, we recommend to read UCI
Reference Guide, which can be downloaded from our website.
https://www.m2mserver.com/m2m-downloads/UCI_Command_Line_Reference_v3.pdf
E.g. you can make a query to ask the current setting of a service (openvpn, ser2net, ddns,
etc. by using the following command from command line):
#uci show service_name
You can also having the option to make detailed settings of a service by using the UCI
interface.
