Switch on
Power switch on panel turns PWK signal to low (ground). Radio turns on supply voltage on pin 8V.
Communication
Both sides communicate at 19200 Baud, 8 bits, no parity, 1 stop bit. Protocol is similar to CI-V control. AFAIK it is not published so next informations are taked by reverse-engineering.
- Packet starts with Preamble code (0xfe).
- Second byte is probably Command number.
- Third byte is probably Sub command number. Mostly 0x00.
- Folowing Data area with variable length.
- Last byte is End of message code (0xfd).
Commands
0x0b
Keepalive packet sent from panel to radio about every 100 ms. When no packet is received by radio in about 200 ms, it switches itself off. To provide reliable work over IP networks, this packet should be emulated.
0x60
Data to display on panel. Looks like bitmask controlling particular LCD segments/LEDs. No detailed description available at this time.
