The following documentation is for the DIN-RYx-N devices CFLink protocol messages.

The TRLYSET (Send) command is used to send a command to the relay channels.

> [F2]<ID>[F3]TRLYSET[F4]<PORT>:<STATE>[F5][F5]

• <PORT> = The relay channel (port) to be controlled. Relay channels would be from P01-P08.
• <STATE> = The command to set the status of relay. 0 would set the relay to open, 1 would set the relay to close, T would set the relay to toggle.

// The reply does not echo the data sent in an effort to reduce bus traffic
< [F2]<ID>[F3]RIRBSND[F4][F5][F5]

The RCV (Receive) notification is generated when either the on-board IR receiver, or the external IR receiver detects an IR signal.

< [F2]<ID>[F3]RIRBRCV[F4]<PORT>:<IR_DATA>[F5][F5]

• <PORT> = The IR port that the IR data was received via. 3 chars, uppercase 'P' followed by the port number (2 digits)
  • P01 = On-board Blaster output
  • P02 = Secondary emitter output
• <IR_DATA> = The IR data generated by the IR Learner software

// IR Data is received via the on-board IR receiver, IR Blaster on CFLink ID [06]
