CONFIG BAUD
Syntax: CONFIG BAUD 0,baud
CONFIG BAUD 1,baud,rs-485
Where:
baud = B a u d r a te n u m be r . S e e ta b le s b el o w .
rs-485 = P a ra m e t er s fo r R S- 4 85 p o rt . S e e ta b le b e lo w .
Specify 0 or 1 for seria l port.
Function: Set baud rates for COM0 and COM 1.
Mode: Comm and, Run
Use: CONFIG BAUD 1,3,OFF
Cards: All. baud code will vary from card to card.
D E S C R IP T I ON
Power up baud rate is 9600 for both ports. Serial param eters change im mediately after this comm and is
exec uted. C omm unica tion pa rame ters are set at 8 d ata bits , 1 stop, n o parity .
Use the table below for COM0 and CO M1 baud code on the RPC-320 and RPC-330:
baud code Baud rate baud code Baud rate
0 38400 (COM0), 57600 (COM 1) 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.
rs-485 Configuration
0 RS-232
1 RS-422 (transmitter and receiver always on)
2 RS-485, 4 wire (Tx on during transmit, receiver always on)
