TPS2(G2)-based Modbus Gateways
Our standard TPS2(G2)-based Modbus Gateways feature four RS232 (MG2240) or RS485 (MG2241) serial ports. Tibbits #01 are used to implement RS232 ports. RS485 ports are "made" with Tibbits #05.
There is one group of nine terminal blocks per two serial ports.
Terminal block assignment is as follows. Notice how there are two separate serial ports per one group of 9 terminal blocks:

TPS2(G2)-based Gateways are powered using our standard 12V power adapters. Gateways equipped with Wi-Fi ports are supplied with external Wi-Fi antennas.
TPS2(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 .
