Serial interfaces
The following serial interfaces are provided:
• RS232 and RS422/485 available on the M/C connector
on the BUC
• FSK available on the IF INPUT connector on the BUC
RS232 interface
The RS232 serial interface supports both the ASCII and the
Codan packet protocols simultaneously. Responses to
commands are returned in the same protocol format as they
are sent. The RS232 serial interface operates with the
following parameters:
The fixed data rate and protocol simplifies the connection
during installation and commissioning, and enables a PC
running a terminal-emulation program to be used to configure
the BUC. For information on protocols, contact your Codan
representative.
The BUC is able to detect the connection of an RS232
interface. When an RS232 interface is used, the BUC inhibits
the use of the Set and Reset commands on the RS422/485 and
FSK interfaces. View and Output commands can still be used
on these interfaces. This functionality is provided for safety
reasons.
data rate 9600 bps
word length 8 bits
parity none
stop bit 1
NOTE
If you disabled transmission, don’t forget to
re-enable it before you remove the RS232
connection.
