TPS3(G2)-based Modbus Gateways

Our standard TPS2(G2)-based Modbus Gateways — MG2342 — feature four universal RS232/422/485 ports. Tibbits #02 are used to implement them. We also can supply models with RS232-only (MG2340) or RS485-only (MG2341) serial ports.

TPS3(G2)-based Gateways are powered using our standard 12V power adapters. Gateways equipped with Wi-Fi ports are supplied with external Wi-Fi antennas.

TPS3(G2) devices have a number of status LEDs. For more information on the device states displayed by the Modbus Gateway app see Understanding LED Signals.
