Cable pinout
Pin Signal Color Description 1 LRXD Yellow Data transfer from front panel to the radio. 2 LTXD Black Data transfer from radio to the front panel. 3 8V Blue DC power (8V) to the front panel. 4 AF Red Output audio to headphone jacket. 5 GND Shield Data, power, output audio and power control ground. 6 MIC White Microphone input. 7 MICE Green shield Microphone ground. 8 PWK White Power control (switch ON button). Active in low.
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.
- Folows Data area with variable length.
- Last byte is End of message code (0xfd).
Commands Panel to Radio
0x01 Buttons 1
Sent state of button group 1.
0x0b Keepalive
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.
Example:
FE 0B 00 FD
Commands Radio to Panel
0x60 Display
Data to display on panel. Looks like bitmask controlling particular LCD segments/LEDs. No detailed description available at this time.
