COM3 (CE4) SETUP
Use the COM3 Setup page to:
• Setup the Modbus RTU as a Master - Gateway, Slave - Gateway, Master - IO, or Modbus Slave.
For Slave, you can choose to communicate via Modbus ASCII or Modbus RTU.
• Select the Modbus Slave addresses.
• Select the Baud Rate, Stop Bits and Parity for the COM3 device on the CE4 RS232 port
These options are the same as for COM1 and COM2 except that COM3 is an RS232 interface for
one-on-one communication or multipoint through a modem.
Note: To use COM3 (RS232) between a Power Xpert Meter Master Gateway and Slave-Gateway,
use a null-modem cable that swaps RX with TX on the 9-pin D connector.
