CONFIG C ommands - 2

CONFIG BAUD

Statement

SYNTAX: CONFIG BAUD port,baud rate, mode, parity [,com]

PURPOSE: To change the ser ial port param eters.

REMARK S: The power– up default for COM1 is:

19,200 baud

8 data bits and 2 stop bits

no parity

The power– up default for COM2 is:

19,200 baud

8 data bits and 1 stop bit

no parity

RS-232

All these par ameter s are pr ogram mable. Once pr ogram med, the serial parameters w ill remain in

place even when the program stops. A reset or another power– up will cause the default values to

be reinstalled.

port is the COM port number. COM 1 is 1, COM2 is 2.

The baud rate parameter is a number from 0 to 7 or 8 which correspond to the baud rates below:

0 150 4 2400 8 38,400 (RPC-2350 only)

1 300 5 4800

2 600 6 9600

3 1200 7 19,200

The mode parameter determ ines the data word length, whether parity is checked, and the number of

stop bits.

0 7 data, no parity, 1 stop 4 8 data, no parity, 1 stop

1 7 data, no parity, 2 stop 5 8 data, no parity, 2 stop

2 7 data, parity, 1 stop 6 8 data, parity, 1 stop

3 7 data, parity, 2 stop 7 8 data, parity, 2 stop

The parity parameter determines the type of parity. Specifying a “0” is even parity and specifying

“1” is odd parity. If the mode parameter is set for no parity, then enter a “ 0”.

com is an optional parameter and is valid only for COM2 on boards with a RS-422/485 port. It

determ ines if this port is R S-232, RS-422, or RS-485. When in R S-485 mode, the output is

automatically turn on when printing and turn off when it is finished. The transmitter is turned off
