Syntax: CONFIG BAUD 0,baud

CONFIG BAUD 1,baud,rs-485

Where: baud = Baud rate number. See tables below.

Specify 0 or 1 for serial port.

Function: Set baud rates for COM0 and COM1.

Mode: Command, Run

Use the table below for COM0 and COM1 baud code on the RPC-320 and RPC-330:

baud code Baud rate baud code Baud rate

0 38400 (COM0), 57600 (COM1) 4 2400

1 19200 5 1200

2 9600 6 600

3 4800 7 300

Notice baud code 0 gives different rates for COM0 and COM 1.

rs-485 configures COM1 for RS-232, RS-422, and 4 wire RS-485. Set jumper W4 as needed. Power up

default is 0, or RS-232 configuration.
