== Using the Kenwood Sovereign Receivers with RS232 Control

THIS CODE IS STILL BEING DEVELOPED

Models are VR 5900, VR 5700, VR 5090 and VR 5080 and maybe other models. Use a null-modem cable DB9 Female at each end. Com settings: 9600,N81

Operational Status

• On/Off works
• Volume & Mute work
• Defined but not tested:
  • Listen Modes (Stereo/Dolby Digital/DTS/DTS-ES/DSP ...)
  • Input Select (CDR/AV1/DVD/TUNER ...)
  • Surround Mode (THX/THX EX)
• OTARadio (AM/FM) not working yet
