Let's say I use my Harmony one remote to turn on my D2v, (D2v turns on the McIntosh MC205) TV and Oppo player. Sometimes everything comes on and works as it should. Sometimes I may have a picture, no sound, eventhough the MC205 got turned on. Sometimes sound no picture. Let's say I started with DVD, get picture no sound. I'll try and select another sorce like TV, wait for it to cycle thru, then back to DVD and find sometime it corrects it and it works, sometimes not. I find I have to turn the D2v off and on, to fix the problem. Do you think one or more of my circuit boards are going bad?
So I was looking into my setting and now I have a question about the 12v trigger. What is Baud Rate, Flow Control and RS-232 TX Status?
Baud rate, which setting... 2400, 4800, 9600, 19200, 38400, 57600, 115200.
Flow control options... none and RTS/CTS.
RS-232 TX Status...off or on?
I don't think one of those setting will help me with the switching problems, but I should confirm I have those set correctly.
Leave those at the factory default settings unless you NEED to change one of them because you are using a type of remote control that connects to the serial port on the D2v.
You can see the default settings in a picture in the Manual. Or you can go into Setup and Save User Settings, Reload Factory Defaults, note down the default settings, and then Load User Settings to get back where you were. Adjust those back to the defaults.
That said, I seriously doubt any setting in there has any bearing on the problem you are trying to fix with your power up sequence.
The usual advice for power up problems is to power things up in reverse order of the HDMI connections. I.e., TV on first, then wait, then D2v on, then wait, then Source device on.
In the configuration for your Harmony, you can control the power-on order for devices for each Activity. You can also specify a power on delay for each device -- how much the Harmony waits before going to the next step when it turns something on.
The usual problem in power up order is the displays. They are slow to get their act together on power up and thus don't respond properly when the HDMI handshakes start. The reason why audio is sometimes affected is that HDMI is an end to end protocol. So the establishment of the correct connection between the Source and the D2v also depends on things going right between the D2v and the TV.
Before fiddling with the Harmony setup. TEST THIS by getting the original remotes for each device and MANUALLY powering them up in the suggested order and with a significant delay after each device powers up and before you power up the next device. If you find this ordering works well with the original remotes THEN is the time to start fiddling with your Harmony setup.
There's a whole Forum here devoted to programmable remotes where you can get advice on how to find the correct adjustments in your Harmony configuration.
When switching between Sources, the power up delay in the Harmony also comes into play as, by default, the Harmony turns devices off and back on again as it thinks you are using them.
In addition, there's ANOTHER delay setting -- a pause after Source Selection, which says how long the Harmony waits after given the new Source Selection command to the D2v before it sends subsequent commands.
To see if your problem is power on/off related for the Sources, you can temporarily set the Harmony to LEAVE EACH DEVICE ON all the time -- even when it is not used in the current Activity. If you find your Source switching works better that way, then, again adjusting the power on delay in the Harmony configuration for each device may do the trick.
If you find you are still having problems even when using the original device remote controls -- so you can do commands manually with any arbitrary amount of delay -- then that suggests what's really going on here is an HDMI cabling problem.
Test this by temporarily setting each Source, AND ALSO the output of the D2v to 480p. 480p (not 480i) is the "simplest" signal for HDMI. See if Source switching now works. Then try 1080i. Then back to 1080p. If you find things work OK when using 480p and 1080i, but not when using 1080p, then that is strong evidence that your HDMI cabling is marginal. This could be as simple as a plug having shifted a bit in its socket. They are only friction fit, and even the weight of the cable can cause them to shift.
