Configuring Teltonika RUT241

Teltonika RUT241

The configuration interface and features of the RUT241 are similar to those of the TRB140.

It can be used with a SIM card and in a "Climkit Cloud Gateway" configuration.

The RUT241 offers additional capabilities compared to the TRB140:

  • broadcasting its own Wi-Fi network
  • connecting to an existing Wi-Fi network (see below)
  • connecting via Ethernet to an existing network using its WAN port
  • using both ports as LAN ports to connect two devices without an additional switch

Change the router's IP

When the RUT240 is used to create a subnet, change its IP address to 192.168.2.1 to avoid confusion with the main network where the router is usually 192.168.1.1.

Create a Wi-Fi WAN Interface

A Wi-Fi WAN interface allows the RUT241 router to connect to the internet (WAN) via an existing Wi-Fi network broadcast by a main router connected to the internet.

Devices can then be connected to the RUT241's LAN port via an Ethernet cable.

This configuration is ideal when Wi-Fi is available in a technical room or parking lot, thus avoiding the use of 4G.

  1. NETWORK > WIRELESS > SCAN. Select the Wifi network and click JOIN NETWORK
  2. Enter the Wi-Fi network password under WPA Passphrase. Choose a name and create wan

Use the main router's DHCP server

Use the main router's DHCP server so that devices connected to the RUT241 obtain an IP address from the main router in the 192.168.1.x range, instead of 192.168.2.x.

  1. Install the "Relay configuration" package.
  1. Under Network > Interfaces > LAN: Disable the DHCP server for the LAN interface (set to disabled), enable "Relay configuration", and select the Wi-Fi WAN interface created above.
  1. To reconnect to the RUT241 configuration interface, change the Ethernet interface network settings on your computer to a static IP. Assign it an IP address such as 192.168.2.10 and a router/gateway of 192.168.2.1. Connect to the address 192.168.2.1 in your web browser.

Configure MQTT Gateway

Update the firmware with version RUT2_R_00.07.02.7_WEBUI.bin.

Under SERVICES > PACKAGE MANAGER > PACKAGES, search for and install the packages by clicking +:

  • MQTT-MODBUS-gateway
  • MODBUS TCP Master

Then configure as described in the section Cloud Gateway Configuration (MQTT)
