RS-232 and Ethernet
Control
The MUSE pre-amp processor is designed for simple,
reliable control in a variety of system configurations. This
section details the control protocols and specs for
interfacing MUSE with a computer and/or 3
automation system.
RS-232
The MUSE pre-amp processor uses a standard RS-232
(DB-9) connection. A Null Modem Cable must be used to
connect to the RS-232 connector located on the back of
the pre-amp processor. The RS-232 Control system is
functional right out of the box.
The RS-232 (DB-9) pin out is defined in the tabled below:

2 TX DATA (Transmit)
3 RX DATA (Receive)

Serial communications format is as follows:

Baud Rate
Data Bits

Flow Control
The MUSE pre-amp processor is design to receive serial
commands and execute upon receiving the command.
This simple format allows for very efficient communication
between the pre-amp processor and the control system.
SEND COMMAND FORMAT:
QQQXXX
Where:
QQQ = category code (typically 3 ASCII characters)
XXX = command code (typically 3 ASCII characters)

Acurus MUSE Immersive Processor USER GUIDE
EXAMPLE - SEND COMMAND:
PWRTGL
This command string will toggle the current power state of
the MUSE.
VERBOSE RESPONSE
Verbose response mode returns human-readable
confirmation messages in response to system changes or
adjustments (originating from any source). For the above
example command, here is the verbose response:
OK, Power On
To enable verbose response, the following serial command
must be issued prior:
VERBON (verbose serial mode on command)
Command Sequencing
Preload and Go! - RS-232 / UDP Command Application
A unique feature of MUSE control via RS-232 and UDP/IP
commands is the ability to send and read operating
parameters while the ACT4 is still in the standby state.
This allows a 3 rd party control system to the power on the
MUSE in a predetermined state resulting in smoother
behavior for the end user.
EXAMPLE: The control system could set the MUSE to
HDMI input 3, then set the volume level to 35, then turn the
power ON. The MUSE would power ON very quickly and
then all of these settings would already be loaded.
Mute and Update - RS-232 / UDP Command
Application
Another unique control option is that a control system
could MUTE the MUSE and then change inputs, volume
level, and other parameters during MUTE.
EXAMPLE: The MUSE would receive the MUTE ON
command and then the control system would switch to
another input, set the volume level to, say, 60, then deliver
the MUTE OFF command.
