Teltonika RUT241

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

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

The RUT241 offers, in addition to the TRB140:

  • the ability to create its own Wi-Fi network
  • connect to an existing Wi-Fi network (see below)
  • connect via Ethernet to an existing network through its WAN port
  • use both ports in LAN mode to connect two devices without utilizing an additional switch

Change the Router 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, which usually has the router at 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) through an existing Wi-Fi network issued by a main router connected to the internet.

Devices can then be connected to the LAN port of the RUT241 via Ethernet cable.

This configuration is ideal if Wi-Fi can be received in a technical room or parking lot, thus avoiding the use of 4G.

  1. NETWORK > WIRELESS > SCAN. Select the Wi-Fi network and click on 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 192.168.1.x and not in 192.168.2.x.

  1. Install the "Relay configuration" package.
  1. Under Network > Interfaces > LAN: Disable the DHCP server of the LAN interface (disabled), enable "Relay configuration," and select the WAN interface created above via Wi-Fi.
  1. To reconnect to the configuration interface of the RUT241, change the network settings of the Ethernet interface of 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 on +:

  • MQTT-MODBUS-gateway
  • MODBUS TCP Master

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