1.Connect the MODBUS Network to the RS-485 Connector on the E2 PIB board (Belden 8641 recommended).

2.Note to wire the RS-485 +/- polarity at the E2 in the reverse of the XEV22D device.

3.Position the three termination jumpers to the UP (terminated) position to provide RS-485 termination at the E2.

4.Do not connect the shield of the MODBUS network to the E2 PIB center terminal. Instead, use a 100 ohm ½ watt resistor to connect the MODBUS cable shield to earth ground.

5.At the XEV22 device, wire the MODBUS cable to the RS-485 +/- terminals and connect the MODBUS shield to the pin 16 terminal.

6.Terminate the end of the MODBUS network at the last device on the daisy chain with the MODBUS termination block

(P/N 535-2711), or by connecting a 150 ohm resistor between the MODBUS +/- terminals.

For more information, please refer to the XVE22D user manual P/N 026-1206.
