7.3.2.2 MC-12 Response
The MC-12 will reset, clear any saved system and effect parameters in Nonvolatile RAM, and restore the
factory default system and effect parameters. After reset the MC-12 will go through a soft power-up
initialization. This includes transmitting the “Wakeup Notification Packet”.
7.3.3 MC-1 Send IR Command (MC-12, MC-1)
Transmits MC-1 IR command key codes to the MC-12.
This command has been maintained for backward compatibility to the MC-1. The MC-1 IR code
functionality has been mapped to the MC-12 IR code functionality as per the MC-1 to MC-12 IR code
table. MC-12 users should use the command described in 7.3.40 (MC-12_Send_IR_Command).
