Lexicon MC-12HD Serial Communications Protocol
5.2 Send MC-12HD IR Command Example
SOP DLL DC CMD AppDC DATA0 EOP
IR Key
Code
F1 04 39 01 28 F2
This example shows how to transmit the IR command for “MAIN_GAME”. This example command will select
the GAME input for the Main Zone. The bytes are transmitted from left to right and they
are defined as:
Byte 0: Start of Packet(F1 hex)
Byte 1: Data Link Layer(DLL) Data Count(DC); for an IR command this would be 4 bytes to
follow
Byte 2: The Application Layer Command, in this case it is 39 hex indicating this is an IR
command packet.
Byte 3: The Application Layer Data Count(DC); for this packet it is 1 data byte to follow.
Byte 4: The Application Command Data: This IR Command Packet is transmitting Key Code
“
MAIN_GAME”(28 hex). To transmit other IR Key Codes the user would replace this byte with
other IR key codes as found in
Appendix D MC-12HD IR Codes.
Byte 5: End of Packet (F2 hex)

There are two products MC-12HD and MC12HDEQ. The following table is for MC12HD V1.00 reference
only. For the EQ version use the
MC12HDEQ Parameter ID List. These Parameter Id Values will change
with S/W and Protocol version changes. The MC12HD can always be queried for the correct Parameter
Id numbers and Parameter Definition Packets.
