All of the messages described in this document can be sent to any of the controllers in the system
by simply changing the Target Controller ID to match the controller you would like to send the
message to.
The following examples show the Volume Up command being sent to the same zone (Zone 1)
but on different controllers using Keypad Event messages:
Byte # 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21
Value F0 00 00 7F 00 01 70 05 02 02 00 00 7F 00 00 00 00 00 01 7C F7
Byte # 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21
Value F0 01 00 7F 00 01 70 05 02 02 00 00 7F 00 00 00 00 00 01 7D F7
Byte # 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21
Value F0 05 00 7F 00 01 70 05 02 02 00 00 7F 00 00 00 00 00 01 01 F7
Byte #2 shows the Controller ID (Zero Based) that the message is being sent to.
NOTE: Remember to recalculate the checksum or the message will be rejected by the controller.
4.1.2.2 Target Zone (Port) ID
Zone ID defines the zone for a particular device. For keypads, this defines which zone port on
the Controllers rear panel that the keypad is connected to. The following special Zone ID values
have been defined:
Here is a list of special Target Zone (Port) ID values:
Value (Hex)
7F
7E
7D
7C
Aside from these values and those for the actual ports on the back of a controller, 0x00 – 0x03
for 4 zone controllers and 0x00 – 0x05 for 6 zone controllers, and 0x7D for a Peripheral Device,
any value can be used for the Zone ID field.
4.1.2.3 Target Keypad ID
Keypad ID identifies particular Keypads sharing a single zone on the controller or the Source
Number of an Internal Tuner (AM/FM or XM for CAM only) when the Zone ID is set as
Peripheral. For keypads, these are numbered 0x00 – 0x05. For Peripheral Tuners, these are also
numbered 0x00 – 0x05. The following values have specific meaning in the system:
Value (Hex)
7F
Reserved
Controller Link
Peripheral Device (Internal Tuner, ST2-XM, etc...)
Trace
The Controller Itself
