Software Revision
The information contained in this document is intended to control AVPs with the latest revision of
software and hardware. This section describes the necessary hardware and software needed to
control an AVP via RS-232.
Before programming and installing the AVP, please verify that the AVP contains the following.
Software in the AVP must be v3.13. The following describes how to identify software in
an AVP.

Identifying
Hardware A change was made to the way an AVP is controlled via RS-232. To ensure that the
AVP will function correctly the following parts must be installed in the AVP.
Part # 770445 New UI front panel chip
Part # 770451 New Software flashchip
The parts listed above store the downloadable software, IR and RS-232 control of the
AVP. Any AVP that contains software higher then v3.13 has these parts. The above
parts can NOTbe used with software below v3.13.
Retrieving
Software
The software can be found on the Madrigal Software Website. Please refer to Technical

Connection
RS-232 Port
Location
RS-232 control is through an RJ-11 connector located on the back of the AVP next
to the IR output. This connector has 6 pins of which only three are used for
communication.

Configuration.
The AVP will receive control data on pin 2 Data Receive and transmit status data
on pin 3 Data Transmit. The connection Cable between the AVP and the control
device will need to be configured so that the AVPs receive is connected to the
control devices transmit. Please refer to the product owner’s manual for the control
device you are using for RS-232 port type and configuration.

Cable
Madrigal Audio Labs offers several parts to help communicate via RS-232 to the
AVP. The following parts can be order from Madrigal Audio Labs Technical Support.
Part # Description
MRC878 DSUB9 to RJ-11 Adaptor and 2 meter RJ-11 to
RJ-11 Cable
MRC808 DSUB9 to RJ-11 Adaptor
MLC732 2 meter RJ-11 to RJ-11 Cable
(Length of Cable RJ-11
to RJ-11) RJ-11 to RJ-11 cable required length
For general purpose and short cable runs to the AVP, Part # MRC878 contains
everything needed.
For cable lengths of more then 2 meters -Part # MRC808 and the length of cable
needed should be ordered.
RS-232 control units with port types other then DSUB9 will need to have the cable
constructed. To construct a cable please follow the example below.
Control Cable
Example
As an example on making the cable we will use the most common connector used,
which is a DSUB9. The AVP only needs 3 pins to control the unit via RS-232. As
mentioned earlier the AVPs pin 2 Data Receive must connect to the control devices
Transmit. Please read the notes below before constructing the RS-232 cable.

AVP Configuration
The AVP will receive RS-232 commands without any setup required. However if you chose the AVP
can be set up to ignore the Checksum (CRC) at the end of the command string. By setting the AVP to
ignore the CRC, it will not send out an acknowledgement to the control system.
NOTE: The command list contained in this document shows the complete string for the command
with the correct CRC included. These strings listed in this document should be in whole used even if
the CRC is turned off.
Setting the AVP to ignore CRC
1. Press and HOLD the recall button on the front of the AVP until the MENU appears on the monitor
and the AVP Display reads OSD ACTIVE
2. Before pressing and other buttons Press and Release the SUB button on the AVP followed by the
MASTER button. These buttons must be pressed within 2 seconds of each other
3. A Technical Menu will appear on the monitor. Using the VOLUME control scroll down to CRC.
4. Press the MUTE button on the front of the AVP to select CRC. Use the volume control to change
the setting to OFF.
5. Press MUTE on the front panel to save the change.
6. Press and Release recall until MENUs are exited.
RS-232 Format
The control device must be set to the following settings to communicate with the AVP.
Baud rate 9600
Start bit One
Data bits Eight
Stop bit. One
Parity None

AVP RS-232 Quick Guide Page 7
Command Strings
The AVP command strings are hexadecimal format. When programming the strings please follow the
guidelines of the control system being used for hexadecimal data.
Hexadecimal data is a series of numbers and letters that make up a byte. All command strings listed
here are shown with spaces between the bytes of data but the spaces are not part of the command
needed. Each control system will specify a separator to be used between bytes or a method to
identify the byte as hex. Please refer to the control system manual for proper sting byte separation
and hex identification.
Examples
Crestron requires a \xin front of each section of the command to see the value as HEX. Without the
\xthe AVP will not respond to the command.
