Chapter 1. Device configuration (OpenWrt user interface)
1.1 Web user interface
Important!
The device software contains a pre-configured system. Please check the configuration, and if
the settings are not match with your expectations, change the configuration settings and save
them.
1. Configure the Ethernet interface’s on your PC for TCP/IPv4 protocol for setup the IP
address: 192.168.127.100 and subnet mask: 255.255.255.0
2. Start the device. The local web user interface (LuCi®)will be reachable after 1-2 minutes
through the Ethernet (LAN)interface –on the device’s default IP address in a web browser.
3. Open the device’s local website in the Mozilla Firefox browser, where the default web user
interface address on Ethernet port is: https://192.168.127.1:8888
Login with the Username: root , Password: wmrpwd and push to the Login button.

1.2 Dashboard (Main page)
After you have logged to the web interface, a startup screen appears with all relevant information
and the current status of the device.
At the System part, you can check the installed software build (Firmware Version) where it
should be 202108271_RC or newer. (If it has an older version, then refresh the firmware, please.)
At the Local Time you can check the current time.
The Uptime shows the spent time interval since the last bootup (or reboot).

At the Modem part, first you can the module’s MEID identifier (IMEI) and the SIM ID identifier of
the used SIM card.
You can also check the wireless modem availability, current status and health at Modem RSSI
(cellular network signal strength) and Modem SQ. (The lower RSSI means better cellular signal
strength / higher SQ value means the better signal quality level).
At the CREG field you can get more info about the used cellular network cells. The COPS shows
the connected network name.
At the Network part, you can see the used cellular network IP address at the Address field.

Chapter 2. Important notes
•By security reasons, we do recommend to change the web user inteface login and
password as soon as you can.
•The IPv6 protocol is disabled for the LAN interface by default, change it if you want to use
it instead of the IPv4 protocol. Use the Network / Interfaces menu LAN interface and the
IPv6 relevant fields.
•The DHCP service is active, therefore the device will giving IP addresses for the connected
devices, but the protocol which is used, configured for static IP addresses for the ethernet
interfaces. If you want to use and distribute IP addresses by DHCP, change its protocol to
DHCP client. You can change its settings in the Network / DHCP and DNS settings menu or
in the Network / Interfaces menu, LAN interface and DHCP section.
•The Firewall service is active by default (by security reasons), therefore all communication
is disabled excluding the used ethernet, DHCP, DNS and WAN channels, web port and the
necessary services and ports for normal operation for the modem.
•We recommend you to disable all ports and protocols in the firewall which you are not using
actively or which are not necessary to the connection and data transmitting by respecting
the ports which are necessary for the general operation. Use to check Status / Firewall
menu to check the data throughput and the Network / Firewall to configure new roles.
•The firewall is not protecting the device against external network or DoS attacks,
if you just enable the firewall feature. For a massive and advanced safety, you have to
customize the settings by harmonized with you used current network and connection
settings.
•We offer to check the network traffic on your modem frequently by the Status /
Firewall menu option to be ensured that all of your connections and active communication
channels (port number, incoming IP) are using only the wanted paths and routes and
listening the defined incoming activities and consequently occuring the estimated output
traffic.
•We offer to measure your throughput data and network traffic (by minutes, hours) –
use the Status / Realtime Graphs or Statistics / Graphs and calculate the estimable
data transmitting amount according your expectations and the data limits of the used SIM
card.
•By default, the modem has an installed OpenWRT®operating system which is ready to use
and configure to your SIM card APN and for you usage requirements.

•The device has 4G LTE wireless transmission capabilities and 2G/3G fallback in case of the
unavailability of the 4G network. In this case, the device will operating on the 3G or 2G
network. When the 4G network will be available again, the device will switch back to the 4G
network. This feature is configurable for the WAN interface of the device.
•You can check the current cellular signal reception and wireless availability in the OpenWRT®
/ LuCi®system’s Overview menu.
•The available APN settings will be assured by the SIM card provider mobile operator or your
mobile internet service provider. Ask them about APN , password, SIM PIN and further
necessary information for the configuration.
•If you want to use the device on the wired network (LAN) with RS485 option, then remove
the WAN interface by the Delete button in the Network / Interfaces menu. The device
will not be restarted further - even if there is no SIM card inserted.
• The RS485 port should be configured before usage, which can be found in the Services /
Ser2net menu. There you can configure RS485 data speed rate betweeen 300 baud and
115 200 baud, but please consider that max. 19 200 baud is guaranteed to receive by the
device. Note, that we offer to use 9 600 baud or 2 400 baud speed rate, which is standard
and there can be guaranteed that it will work. With higher data speed rates some connected
systems can cause loss of characters/data in case of some connected device(s).
•Note that the device is not detecting the relay connections, it is just signaling the relay switch
by the REL.1..4 LEDs. The compatibility settings should be done at the Router / Relay
Switch menu.
•Note that all relays are latching relays, which means the device remains the last switching
status (even if the power was taken). The Relay 1 and Relay 2 having NC, NO, COM pins
(and it has two switching mode, where the SET and RESET are also available) while the
Relay 3 and Relay 4having only NC and COM pins (does not have RESET, just SET).
•Note, that the device has supercapacitor component inside, which protects the device against
possible shorter power outages. In case of a power outage - due to the supercapacitors –
the device has enough enegy to provide a safe disconnection and shutdown (before the
supercaps will be exhausted). The same if you store the device for months without connecting
a power source or using it. Therefore, this component must be charged before usage. When
powering the device, the charge of the supercapacitors will be started automatically. The
system will be started by the device only after the end of the charge process.

Chapter 3. Network configuration
3.1 Interface settings
The list of the available network interfaces can be found at the Network / Interfaces menu item.
The LAN interface is listed for configuring and using the device with your PC or an external device
through the Ethernet connection ( eth0 interface).
The WAN interface means the wireless Internet connection (as 4g-wan ) the physical 4G cellular
module.
Modifying the interface settings
At the interfaces, at right you can modify the settings with the button.
The Stop button stops the communication on the current interface, the button reconnects
the related interface connection.
3.2 Cellular internet (WAN) settings
The wireless module / cellular network settings of the modem can be configured at the Network
menu, Interfaces menu item. Open the WAN item from the interface list by the Edit button.

The wireless connection can be operated through the dynamic and static IP address (IPv4)
assignment also - which is provided by your mobile operator.
At the General Setup tab, you can see the current status of the interface with transmitted data
amount.

The device detects the 4G module and configuring. You only have to setup the APN you want to
use for the WAN ( ppp-4g ) interface and the PIN code of the SIM (if it is presented).
The Wireless Network field gives you the opportunity to choose a
dedicated cellular technology or you can leave it on default value:
4G/3G/2G –which means the Auto mode.
This mode could grant the best speed and quality option (for 4G
selection), or the garanteed operation on any network ( fallback feature
for 4G/3G/2G selection (when the 4G cellular network service is not
available the 3G will be used –it 3G is not available, or 2G fallback will be used –when 3G or 4G
will be available again, it will switch back to 4G) –if the internet module of the device’s
supporting this.
If you have to use a dedicated network like 3G, 2G, etc., then choose the required network type,
please. But take consider, that the „fallback”feature will be inactive in this mode –if you
choose the 4G and it the network will be not available, there will not be provided 3G or 2G fallback
(if the choosen network is not available, the device won’t get mobile network access). For fallback
always choose the Auto mode (4G/3G/2G setting).
If you choose the No change option, the device will be using the last known good configuration
here.
There you can also define the SIM #1 APN name for the Internet connection, which is necessary
to use. If you will not set any value for the APN , the modem will restart the modem sequentially
in every ca. 10 minutes until it is not configured properly.
You can define SIM card’s PIN code here - if it is necessary for the connection.
Note, that the PIN code which is already configured here, it cannot be seen here due to the security
rules –the characters are placed by asterix signs. Just modify the PIN if you would like to change.
Important! If you need to change the PIN code, use the Network / SIM PIN Change menu item.
Authentication methods:
•The SIM #1 PAP/CHAP username and SIM #1 PAP/CHAP password settings can be
also configured here –if it is required for the connection.

•If you need dialup connection for using the Internet service at your provider, set the Dial
number value (format: *99***1# ).
In case of roaming change the Mobile country code (MCC) settings to the related country code
please. If you are attempting to use a dedicated cellular network, configure the MNC field (Mobile
network code) please, according the needs. You will found the currently useable MCC / MNC
settings here: https://www.mcc-mnc.com/
Click to the Save & Apply button for saving the settings, while the device will be restarting the
cellular module with the new settings and will connecting to the cellular network.
Then, you can check the data transmitting at the Network / Interfaces menu, when check the
WAN interface status at the Interfaces part.
The device is already connected to the cellular network, it has active data traffic and the RX
(received data), TX (transmitted data) at Pkts. (number of network packets) and KB (KBytes)
values are growing.
The WAN interface data traffic will be signed by the red flashing of the WAN LED (together with
the green flashing of the LAN) –which all can be indentified as yellow.
At the Advanced Settings tab you will found further settings for the wireless module.
By default we do not offer to change these settings, only if you are special requirements at operating
the mobile network communication by the modem (these are the LCP Echo settings, the Bring up
on boot and the use built-in IPv6 management parameters mainly).
If you changed the configuration here, click upon Save & Apply button for saving the settings.
Then the device will reconnecting the module to the mobile network.

3.3 Ethernet (LAN) settings
The detailed interface settings for the LAN Ethernet port ( eth0 ) can be performed by selecting the
Network / Interfaces menu item.
At the LAN interface’s button, choose the General Setup tab.
By default the Ethernet IP address is static , the default IP address is: 192.168.127.1.). If you want
to switch the LAN ( eth0 )interface to dynamic (at Protocol field), then the device will waiting for
an IP address on the network.

Define a new IPv4 address, check the IPv4 netmask (subnet mask), IPv4 gateway values for
your devices according to your needs –to be able to serve your connecting devices.
When changing the Protocol field, you need to push the button.
If you want to use the local DHCP server –to allow to add IP addresses by the device for the
connecting external ethernet devices –then the right setting is the Static Address , and the IP
address should be also changed, and you have to uncheck the DHCP disabled option for the LAN
interface to allow the DHCP server.
Save your settings by the Save & Apply button, and the LAN interface IP address will be changed
according your request due to the new settings.
3.4 DHCP and DNS
The DHCP and DNS settings can be achieved at Network menu, DHCP and DNS item at General
Settings.
Below, at the Active DHCP Leases part you can see the list of the devices, which given their IP
addresses from the modem’s DHCP service (with the renewal lease time ).

To enable DHCP, uncheck the Ignore interface option. The fields required for DHCP configuration
and their default values are displayed.
The Start field means the starting address within the subnet used by the router (in our case
192.168.x…).
Use the Limit field to limit how many IP addresses are assigned. That is, the router on subnet
192.168.x will assign IP addresses in the address range between Start and Start + Limit to the
devices that want to connect.
Further settings can be achieved at the Advanced Settings tab (as dynamic DHCP, IPv4 Netmask ).
Save your settings with the Save & Apply button.

Further DHCP server settings can be found in the Network / DHCP and DNS menu. Here you
can see and configure them under the General Settings tab.
At the Static Leases you can add network devices by the button to be guaranteed to get
the same IP address after every leade time renewal. Define a Hostname and the valid MAC-
Address of the device and the required IPv4-Address.
