This driver controls the very popular Denon 3803 A/V receiver. This receiver has a good set of features, and a pretty good control protocol that allows for a considerable amount of control. Note that these models also are packaged in non-US markets as the AVC-3570, so this driver would control that model as well.
This driver is CML based and the classes are found in the CML scope MEng.System.CQC.Drivers.Denon.3803.DriverImpl.
None known at this time.
The Denon uses a serial connection. It has a non-standard connector, which uses a stereo 1/8th inch phono plug. The pin connections are:
Tip -> Pin 2 (receive) Middle -> Pin 3 (send) Sleave -> Pin 5 (ground)The parameters are 9,600 baud, 8 bits, one stop bit, no parity. That's a little slow, but the protocol is fairly compact, and it sends notifications so the driver only needs to do a full set of queries at connect time.
The protocol is plain ASCII, so it is trivial to confirm that your cabling is correct by using a terminal server program. For instance, to get the master volume, type MV? and press enter. It will send back MVxx, where xx is the value of the master volume, based on an 0 to 98 range (-80 to 18db.) You can also make changes via the remote control and see them show up as the Denon sends notifications out the serial port. Given the ease of validating the connection on this device, and the non-standard cable type, definitely do it before connecting CQC to it, so that you know that everything is correct before you start.
This section lists the fields that the driver makes available, their types, minimum and maximum values, etc...
Name Type R/W Description/Limits CinemaEQ Boolean W Enables or disables the Cinema EQ feature DigInMode String W Set the digital mode to use for the current input. It is an enumerated field which has legal values of: Auto, PCM, DTS, Analog, ExtIn MasterVol Int R/W Read or set the volume of the Denon. It is an integral value limited to the range of -80 to to 18, which represent dB values. MasterVolAdj Boolean W Write true to move the master volume up, and false to move it down. Mode String R/W Read or set effect mode. It is an enumerated field which has legal values of: Direct, PureDirect, Stereo, DolbyProLogic, DolbyPLII, DolbyDigital, DolbyDigitalEx, DTSNEO6, DTSSurround, DTSESDiscrete, DTSESMatrix, WideScreen, Stereo5Ch, Stereo7Ch, SuperStadium, RockArena, JazzClub, ClassicConcert, MonoMovie, VideoGame, Matrix, Virtual Mute Boolean R/W Read or set the mute state. A true value mutes the unit, and a false value un-mutes. MZPower Boolean R/W Read or set the main zone power state. Power Boolean R/W Read or set the power state. SrcInput String R/W Read or set the input source to monitor. It is an enumerated field which has legal values of: Phono, CD, Tuner, DVD, VDP, TV, Sat, VCR1, VCR2, Aux, Tape1, Source TunerFreq String R Allows you to read the current tuner frequency, which will be in the usual floating point format, i.e. a frequency a period then a fractional frequency. TunerMode String R/W Read or set the tuner mode. It is an enumerated field that has the values: Auto, Manual. TunerPreset String W Read or write the tuner preset. They are in the form A1, B2, C3, etc... They go from A1 to E8. Z2Power Boolean R/W Read or set the Zone 2 power state. Z2SrcInput String R/W Read or set the source for zone 2. The values are the same as those for the SrcInput field above. Z2Volume Int R/W Read or set the Zone 2 volume. It has the same values as the MasterVol field above. Z2VolumeAdj Boolean W Write true to move the Zone 2 volume up, and false to move it down.
