Rs232 Commands - Meridian DSP750 User Manual

In-wall Digital Active Loudspeaker User Guide
DSP
RS commands
RS232 is one of several interfaces carried by the Meridian
Speakerlink RJ45/Cat5 connection. The Meridian Distributor and
the Meridian AC12 make this interface available on a standard
RS232 connector.
Port settings
9600 Baud, 8 data bits, 1 stop bit, no parity, no flow control
Command format
RS232 commands consist of ASCII characters which are case
sensitive. Some commands require parameters, so these are
followed by additional characters. All commands are terminated
with a carriage return. For example:
To change the volume level to 45, the command is: VN45
This will cause the loudspeaker to change its volume and
respond with: Volume 45
Non-volatile configuration and reset
Some of the RS232 commands described in this document
produce non-volatile (lasting) configuration changes in the DSP
loudspeaker. These commands should be used carefully because
they may affect the sound and operation of the loudspeaker
without giving any obvious external indications.
An RS232 command is provided to reset the loudspeaker to its
default configuration. For loudspeakers with IR receivers such
as DSP520 and DSP640, the loudspeaker may also be reset by
powering-up with the stop key pressed on the MSR+ remote
control. This is confirmed by three flashes from the white lights
on the loudspeaker.
