Terminal Block Connector Pin out (dependent on ES Model)
For ES devices with terminal block connectors have the signals detailed below.
i. RS-232 & RS-422/485 Port (e.g. ES-357)
ii. RS-232 1 Port (e.g. ES-020)
For RS-422 FULL Duplex Communications, please note the pin outs above.
To achieve RS-485 Half Duplex Communications on a terminal block, using two wires for
communication, you need to use the “Data” pins marked with D+/D-. E.g. for the ES-357 this would be
Pin 8 and Pin 9.
Once your wiring is setup, you will also need to set the device to FULL or HALF Duplex mode in the
software. For further details, see Section 9
