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.

Terminal block assignment is as follows:
| MG Model --> | MG2340 | MG2341 | MG2342 | ||
| Tibbit used --> | Tibbit #01 | Tibbit #05 | Tibbit #02 | ||
| Terminal block # | RS232 | RS485 | RS232 | RS422 | RS485 | 
| 1 | TX (output) | 485+ | TX (output) | TX+ (output) | TX+ (output) | 
| 2 | RX (input) | 485- | RX (input) | RX- (input) | RX- (input) | 
| 3 | RTS (output) | --- | RTS (output) | RTS+ (output) | --- | 
| 4 | CTS (input) | --- | CTS (input) | CTS+ (input) | --- | 
| 5 | GND | GND | GND | GND | GND | 
| 6 | --- | --- | DTR (output) | TX- (output) | TX- (output) | 
| 7 | --- | --- | DSR (input) | RX+ (input) | RX+ (input) | 
| 8 | --- | --- | --- | RTS- (output) | --- | 
| 9 | --- | --- | --- | CTS- (input) | --- | 
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 .
