So I thought I would make a little note for you all here. I spent two days and 100$ on USB-Serial Cables as well as null modem cables and gender changers.
First I created a RS232 template for the Denon AVR-988 - Write down your template # you will need it later
I set the tuner to OTAradio
I set the XM Input to Satellite Radio Neither of these work yet. I have a feeling I will have to change them both to live-tv and modify the scenario for each.
The Ext 7.1 - Input works on this template for DVD-Audio and SACD. I have mine set to Pure direct mode.
Modes - Use what is listed - There are issues with Denon Modes and rs-232 - Some modes need a parent mode sent first then a child mode IE DTS Surround - DTS Neo Cinema to end up at DTS Neo Cinema. I have been following a few threads on Remote Central and this seems to be a common issue with Denon Modes. I will figure this out and update when completed I also plan on Adding the DTS-HD master and Dobly Digital + and DD True HD modes to the list. When I can get an answer about adding the command in and in fact a mode is an AV Command. But for now all the modes are in the that normally will be used.
Prolific USB-RS232 (Radio Shack Nexxtech) detected the rcvr HAS TO BE A DIRECT CONNECTION, you cannot use the usb-serial and then plug another male to female null cable in it will not detect the device it just runs through all the scripts looking but no device found. In order to do a direct connection you need to remove the stand-offs from the male db9 end on usb-serial cable
Cheap China made device (well 27$) No dice - Light comes on for power but no detection - In the garbage now.
Trendnet - same as above with prolific device - it is working and the one I am using now again a DIRECT connection to the rcvr.
Once your USb-Serial is installed you will need to launch a shell to the core and run lsusb abd get the tty number for your device (this being the USB-serial device) and not the rcvr for mine it is ttyUSB2 but the system is using pci000 ______ _____ +7 you will know what I mean when you see it in your ports listing. Ideally I think if your system detects the rcvr it is USING the right port anyhow, making this step not really required.
Denon PNP script - You will need to modify this and in the last line change the Device template #, likely will be 71 on your local machine ( There is no logic in the script for Device ID) Also could be a denon issue as it looks like all there receivers use the same command sets with just more or less of them. If you do not edit your script it will detect the AVC-A1SA all the time.
Device Template # 1931. You can set yours up the same way as this.
Make note - Stop and Parity Bit need to be N81 not 8N1. I also set the baud rate to 9600 but the more templates I see B9600 in the default value. Mine is working so I am not sure if it matters.
The receiver only needs Standard Receiver Commands at this point to function (from a gyro remote) Also I have not figure out how to toggle the Mute Command, I can mute it but then issue the PWON command to unmute it currently.
Now the issues - My whole problem was two things.
One the 8N1 which I found by looking in webadmin - advanced - device - core - avr-988 (rs232) then click on View Log Errors. This is the key you can view errors, whole log and tail the device from the webadmin. This is how I located the problem and was able to fix it.
I fixed the 8N1 by changing it to N81. then in viewing the whole log - I found that Ruby could not compile the command set due to the errors in the PWON Command Formatting. I fixed that and voila. Now I had to regen the orbiter, and then recheck the log to make sure all the errors were gone. Then I removed (deleted) the rcvr and had it redetect and setup again then reload router and then tested some commands from the webadmin page and they worked.
I still have no volume from the MCE remote for some reason I will figure out later. I reloaded my .Xmodmap from KDE terminal and got the ambience controls working with my Gyration again and I now have volume from the gyration at least. but the LMCE is turning the rcvr on and off with the TV now which is good.
Zaerc - I will add this too the WIKI as soon as I get it completely formatted with the system.
A note when setting up devices - How I screwed up. When I got to the IR/Codes group I chose denon avc protocol. I should have made a new group at that point. As the Denon AVC has a lot of modes and different inputs than the AVR-988. So I chose to delete code from that page thinking it would remove that mode from the list it did not it went to the web and deleted ALL the codes from the master template. I have added them all back in except for a couple inputs and some THX modes which I do not have the commands for.
So In retrospect I would have created a new IR codes template and the same thing will happen if you try to setup a 2808, 3808, 4806, 5808Ci Denon rcvr, you must create a new code group for those. the Denon code group that is there now works with the AVR-988. I am going to go back in a create a AVR-988 code group later and fix the AVC protocol template as well.
