1.6 Understanding the LED signals
The router has 16 LEDs to assign the router current status, the communication, connection.
These LEDs are located in four groups:
-Operation status LEDs (Group A)
oPWR –Power source connected / mains on
oON –The router has started
oSUPERCAPACITOR CHARGE (in case of exhausted supercapacitor it shows the
recharge)
-Connectivity LEDs (Group B)
oRS232 connection and activity (on the RJ12 connector)
oRS485 connection and activity (on the RJ12 connector)
oWAN –wireless network connection and access
oUSBLAN connection (on microUSB port)
oKERNEL –for sign possible failures, stand-by mode
-cellular network signal strength indication LEDs (Group C)
osignal 1 to signal 4: wireless signal reception (higher is better)
-LAN (Ethernet) connectivity LEDs (Group D)
oLAN1 port to LAN4 (by the detected the RJ45 port connection)

The power indication group (group A) and signal level leds (group C) are is fixed, but the other 9
LEDs (group B and group D) are free to reonfigurable.

2. Installing the router
2.1 The very first startup
The router has a supercapacitor inside which can protect the device against short (<5sec) power
outages. Therefore this part can be charged and it can be exhausted after an outage or if you store
the router for months without connecting power source or using.
In these cases you cannot start the router as usual by adding the DC power supply only, because
only the PWR led will be active (lighing by green), but the router won’t start further.
First, you must start the router by the adding the power source and pushing the Reset button
(No. 11) for 2 seconds by a sharp object (e.g. by a pen) –while the ON led will be also active (all
the two leds are lighting by green colour) –then you can release the Reset button.
Then the router will start immediately and charging the supercapacitor (SUPERCAPACITOR
CHARGE led will be also active –by yellow colour).
Next time you don’t need to push the Reset. You can stop it by removing the power source and
start it by adding the DC power.

2.2 Normal startup
The router has a pre-installed system (which contains the router firmware and the pre-configured
OpenWrt®system).
After adding power source to the router you will just need to configure some necessary and unique
settings for your SIM card, network access, and some other required connection parameters.
Please, start the router by the following sequence.
1. Ensure that you have inserted an activated SIM card into SIM 1 holder (No. 4) in the right
position. The usage of SIM 1 holder is obligatory to use for wireless communication.
2. Only if you are using DUAL SIM version, insert active SIM card into SIM 2 titled holder also.
3. Ensure that antennas are mounted to the SMA interfaces (No. 12 and 13).
4. After plugging the DC Power source (No. 1), the router begins to perform booting –the
LED signals are always showing the current activity during the operation.
The system start needs about 40-50 seconds while it will be ready for usage, network
communication.
5. During the boot, the router begins to operate, whereas its LED signals are showing the
current activity during the operation.
Boot sequence:
a.) First the LAN1 –LAN4 leds are blinking for half a second, which signs that the power was
added. The PWR and ON leds are also active (lighing by green).
b.) Then the RS232 and RS485 LEDs are ligthing for ~10 seconds during the firmware start.

c.) The RS232, RS485, WAN, USBLAN leds will be flashing during 30 seconds until boot.
d.) At the end of the boot process, only the WAN, USBLAN leds are flashing for 5-10 seconds.
e.) When the connectivity LEDs are not blinking anymore the load of the system has finished.
f.) If the WAN (APN) was not configured, the SIGNAL LEVEL low LED is blinking which means
the router tries to connect to the wireless network. If it will was configured properly (APN,
password and SIM PIN is matching) and the registration was succesful, then the WAN led

will be lighting and the current SIGNAL LEVEL leds will be also lighting its signal strength
value which means connected and you have useful wireless signal reception for the usage
and data transmitting.
g.) If you have already connected the USBLAN or LAN1..LAN4 or the RS232/RS485, the
interface connectivity led will be also active and signing the network connection and data
traffic.
When the router has reached the listed point „e.)” then the device is already accessible on its LAN
and USBLAN interfaces, therefore now you can login to the LuCi®web user interface (or connect
via SSH).
2.3 Local access via Ethernet port (LAN1..LAN4 interfaces)
The router’s default Ethernet IP address is 192.168.1.1
Add the 192.168.1.x IPv4 address (where x can be between 2 and 255) to your computer’s
Ethernet interface for connecting to the router.
Then you can access the device through the web user interface or by SSH.
For connecting to the router on web interface use the https://192.168.1.1 URL.
Important!
The DHCP service is turned on for the Ethernet interfaces, by default.
The ETH1..ETH4 interfaces are bridged, therefore its not important which port are you currently
using, all network data and TCP/IP packets will be relied.

2.4 Local access via USB LAN (USB connection)
1. Download, unpack and install the USBLAN driver for using the USB connection:
http://www.wmsystems.hu/m2m-downloads/USB_Ethernet_RNDIS_DRIVER.zip
2. After you’ve connected the USB-microUSB cable, you can add the driver in the Windows®/
Start / Control Panel / System / Device Manager. Find the Network Cards, extend
it and you will found the „USB Ethernet / RNDIS Gadget”. Double click on the entry and
choose the Driver tab, and the Refresh button, then browse the uncompressed file’s
directory then Install the driver.)
3. Build a connection between the PC and the router with a microUSB-to-USB cable.
4. Configure the USB-Ethernet interface IP address on your PC for the „USB
Ethernet/RNDIS Gadget” and setup the next fixed ipv4 address: 192.168.10.10, subnet
mask is: 255.255.255.0 –connect these settings.
(You can ping the device through the USB connection on its IP address.)
5. The USBLAN interface IP address is 192.168.10.1
For connecting to the router on web interface use the https://192.168.10.1 URL.
2.5 Web user interface and Login
1. The router’s local web user interface (LuCi®) is reachable through the Ethernet or
USB interface –on the default addresses.
2. Enter the router default web user interface (LuCi®) URL.
The Ethernet web interface default URL is: https://192.168.1.1
The USB web interface default URL is: https://192.168.10.1
