LED indicators​

  • Indicators for the network and serial ports show when a connection is open and when data is being transferred.
  • Three-colour status LED provides additional information on the status of the device.

For more information see LED information in the Hardware Features section.

Physical​

  • Plastic enclosure
  • Mounting flanges for wall-mounting or attachment of optional DIN-rail mounting kit

DB9 Connector Pin-out (dependent on ES Model)​

The ES devices which have DB9 connectors have the following set of signals.

RS-232 Port​

DB9 RS-232 Pinout

RS-422/485 Port​

DB9 RS-422/485 Pinout

For RS-422 FULL Duplex Communications, please note the pin outs above.

To achieve RS-485 Half Duplex Communications, using two wires for communication, Pins 1 and 6, 2 and 7 must be physically shorted.

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 the RS-422/485 Settings section.

Terminal Block Connector Pin out (dependent on ES Model)​

For ES devices with terminal block connectors have the signals detailed below.

RS-232 & RS-422/485 Port (e.g. ES-357)​

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 the Advanced Configuration section.
