RS-232 Interface

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 Center at www.russound.com. Look for the Technical Documents under Multi-source/Multi- room products.
