Denon 2808ci Receiver Driver

Denon 2808ci Receiver Driver
Version 1.0

Description:

This driver controls the Denon 2808ci 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.

This driver is CML based and the classes are found in the CML scope MEng.System.CQC.Drivers.Denon.2808ci.DriverImpl.

Release Info

Version 1.0

• Original Version

Quirks and Limitations:

Because the audio effects reported back are not always the same as those set, two fields are used. FXRead shows
the current effect as reported by the receiver, while FXWrite is used to set the effect. Not all effects are available
for all source types. There is currently an issue with 7CH STEREO. When set the receiver will set this mode, but
will no longer allow polling of the effect mode until changed to something else. So FXRead will show last effect before
7CH STEREO was set.

Also, features have been added to allow the display and control of Ipods
directly via CQC. These features show the screen info as displayed in the Denon GUI via 9 display fields. Because these
fields are slow to update, it may take up to 1 second before the next command can be sent. To cut down on the overhead
the fields are only updated when one of the Zones has Ipod selected as it's source.

Tuning commands will not work unless a zone is powered on and it's source is set to the analog or XM tuner. Direct input
of frequencies has been added. If the frequency is less than 500 it is an FM frequency, greater than 500 is an AM frequency.

Warning: Do not leave the driver running while trying to update the Denon's Firmware, you run the risk of bricking the receiver.

I didnt try every single function, but all the ones i used worked great and stable so far.

Can you try to set the FXWrite to 7CHStereo and see if the FXRead reflects that?

On the 3808 it will change to 7CHStereo but the device won't respond to queries for the FX fields until it is changed to something else. So FXRead never says 7CHStereo.

Can't find the driver I am running CQC 2.3.3... Strange I only see the 2807?

Thanks

Hmmm.. I could've sworn it was added in 2.3.x, maybe it was a later release. It definitely looks like it is in 2.4.

I'll PM you a link to the file.

I will have a 2809ci on Thursday. I expect the 232 protocol to be similar except for new features. I will load it up and report back once I do some testing.

Denon doesn't seem to have a protocol document out for it yet, or we could compare functions a lot easier. One difference is these new 09 boxes have Sirius support (and the 3808 and 4308 are getting an optional $100 firmware upgrade to support that as well).

I couldn't find one either. I look again tonight.

I just joined the 2808CI club. My first controllable piece of AV equipment.

I have been using it to control my 2809CI for almost a month and everything I have tried is working. I still want to connect zone 2 to my Russound, but haven't had time.

I think it would be safe to include the 2809CI model for this driver. It may a separate version with some added features down the road, but it is working.
