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.

the main zone. The following table shows the hex value returned and the source
button it represents. The AVPs More inputs are represented but do not have an
associated front panel source button. A list of the more inputs programming should
be kept for reference.

Packet 3 Not Defined –Packet 3 is not defined and thus has no information on system status.
This packet will always return a 08h.
NOTE: The hex value of this packet is the hex value for a backspace. Due to this
certain programs will need to set up to ignore a backspace or the previous packet
will be eliminated from the response. Please refer to the manual for your RS-232
control system on how to turn off the backspace if needed.
Packet 4 Main Zone Video Input Number –Packet 4 shows the current video source of the
AVP. Sources that have a video input defined in setup will follow the table described
in packet 2 above. Sources with no video input defined will show a value of 82hfor
packet 4 indicating that the current source from packet 2 is audio only.

Status Response
AVP RS-232 Quick Guide Page 13
Packet 5 Main Zone Volume –Packet 5 shows the absolute volume of the AVP main zone.
The table in Appendix A shows the hex value returned and the appropriate volume.
NOTE 1: The AVPs volume control does not track all numbers between 0 and max
volume. This includes no half-volume steps until 31.5. The table in appendix A
shows all volume settings of the AVP from 0 to 92 (factory setting for max volume).
NOTE 2: The AVP maybe setup to show the volume in a 0 db RELATIVE scale. The
relative volume setting requires looking at other information in the AVP that is not
available to the status request. To see what the relative volume is the front panel
ASCII information as described in Packets 16 to 27 will need to be used.
Packet 6 Remote Zone Audio Input –Packet 6 shows the current audio source for the
remote zone and follows the source table in packet 2. Please see packet 2 above.
Packet 7 Remote Zone Video Input –Packet 7 shows the current video source for the
remote zone and follows the same return as in packet 4. Please see packet 4 above.
Packet 8 Remote Zone Volume –Packet 8 shows the absolute volume of the AVP remote
zone just as packet 5 shows the main zone volume setting. Please see packet 5
above.
Packet 9 Current Application –The value of this packet shows the current type of digital
application. Analog signals will be 00h.

Packet 10 Status Bits –The value of packet 10 shows the current status of certain AVP
parameters. The parameters include standby state and THX mode as well as others.
Certain values in this packet have no meaning and are not listed. Any value not
listed should be ignored.
NOTE: The hex values will be added together should 2 or more parameters be meet.
Example: THX ON (40) and SUB ON (80). These values would be displayed as C0h.

Front Panel ASCII Display –Packets 16 to 27 are the actual characters displayed on the
AVPs front panel display. These values will show the name of the source and the volume
setting of the AVP. The volume setting can be used to back up the information from packet 5
or packet 8. These values can also be used to determine the relative volume setting should it
be required.
NOTE: The path of the AVP must be changed to REMOTE in order to see the remote zone
values. The following steps allow reading of the remote zone display.
Packet / Character Layout
1. Switch the AVPs path to remote
2. Request the status by sending the status to pc command
3. Look at the ASCII values of the display returned in packet 16 to 27.
The packets start from the left side of the display with packet 16 and end on the right with
packet 27. See Appendix B for the hex to ASCII code list.
