The CAV6.6 supports RS-232 communication
with various third-party automation systems
through the RS-232 ports. These ports are also
used for firmware updates, and for controller
programming through the PC Power Tool soft-
ware program.
The two RS-232 com ports are located on the
front and the back of the CAV6.6 and use a
DB-9 cable connection. Before performing
updates or programming, select a front or rear
RS-232 port and set the Front/Rear RS-232
switch on the front of the controller as well. The
switch is located next to the DB-9 port.
For RS-232 protocol, available firmware updates
and the RNET Backup Utility, see the Document
