C4630 SE HOME AUDIO SYSTEM
Inbound Serial Control of C4630 SEs in Multi-Unit Systems
In systems with multiple C4630 SE units, serial commands in the above format will only control the C4630 SE unit to which
the serial control device is directly connected. However, all of the serial commands in the above table can also be used to
control any C4630 SE in a system with more than one unit, where the serial control device is connected to one ‘Master’
C4630 SE and all of the ‘Slave’ C4630 SEs are connected via their S
YNC connections (see page 16).
Multi-unit commands have the same format as the single-unit commands, with the addition of the C4630 SE’s Unit ID
number (see page 27) inserted between the opening colon (:) and the command letter.
For example, the V
OLUME UP command for Zone 1 in a single-unit system would be:
::VV11++++<<ccrr>>
The V
OLUME UP command for Zone 1 of Unit 3 in a multi-unit system would be:
::33VV11++++<<ccrr>>
C4630 SE Status Queries
C4630 SE status queries follow the same format as the serial commands, except that the SETTING is replaced with a
question mark character (?). The response from the C4630 SE will consist of a plus sign (+) followed by the parameter
being checked, the zone (if applicable) and the current setting.

The C4630 SE will respond with ‘+ERR’ if the status query is invalid.
