Using the RS-232 Communications Port

The PR-4Zi is equipped with one DB-9 connector for RS-232 communication with AMX™, Crestron™, and similar automation systems. All PR-4Zi control functions (except for paging) can be accessed through the RS-232 port. The PR-4Zi will also send confirmation data to the controlling system. These updates will be performed when any change has been executed or when the “SEND ZONE STATUS INFORMATION” request is sent to the PR-4Zi.

CONTROLLER ADDRESS SWITCH SETTINGS

Up to 16 zones can be controlled from a single RS-232

of the DB-9 connector (Figure 21).

 

Controller #1 (Zones 1-4)

Controller #2 (Zones 5-8)

Controller #3 (Zones 9-12)

Controller #4 (Zones 13-16)

RS-232 COMMAND PROTOCOLS

Commands are sent from RS-232 controlling device to the PR-4Zi as 8 ASCII bytes. The first two ASCII bytes “RU” establish that the command is a Russound command for zone commands only. The next 3 bytes “Z01” establish the zone to be controlled. The last 3 bytes “ZON” comprise the com- mand sent to that zone. Commands are sent as ASCII values, asynchronous, 4800 bps, 8 data bits, 1 start bit, 1 stop bit, no parity.

PR-4Zi FEEDBACK BYTES TO CONTROLLING DEVICE

Feedback bytes will be sent immediately after a command is given to the PR-4Zi. The first decimal byte “101” (Zone 1) establishes which zone the update is for. The second decimal byte “40” (min. vol- ume has been set) is the update data. Each update starts with the zone number update value (101 -

116)and is followed by a control update value (see list on next page). Commands are sent as deci- mal values, asynchronous, 4800 bps, 8 data bits, 1 start bit, 1 stop bit, no parity.
