Address Description 5/02
5/01,
Fixed
S:15H Baud Rate
Read/write. This byte value contains a code used to select the baud
rate of the processor on the DH–485 link.
SLC 5/02 processors provide a baud rate of 19200, 9600, 2400, or
1200. SLC 5/01 and fixed processors provide a baud rate of 19200
or 9600 only.
To change the baud rate from the default value of 19200, use either
the EDT_DAT or NODE_CFG functions of your HHT. The processor
uses code 1 for 1200 baud, code 2 for 2400 baud, code 3 for 9600
baud, and code 4 for 19200 baud.
Example showing runtime protection of baud rate 19200
(code 4):
S:15H equal to 4 and S:15L equal to 3
= 1027 decimal = 0403 hex = 0000 0100 0000 0011 binary
S:15H equal to 4
= 1024 decimal = 0400 hex = 0000 0100 0000 0000 binary
Example showing runtime protection for both baud rate 19200 (code
4) and node address 3:
