8810w- How to disable transport keys in TV mode?

bgc99 · Post by **bgc99** » Sun Aug 09, 2009 11:27 pm

I built an upgrade for my TV, it's assigned to TV button and works fine. I've got the VCR button assigned to builtin code 0043 and the AUX button assigned to a Tivo upgrade I built.

When I am in TV mode, if I accidentally hit play it causes my VCR to turn on and start playing (it's normal for it to turn on when play is hit). I thought it might have something to do with the HT transport device setting in IR so I changed that to CD but the problem persists.

Why is the play button sending to the VCR when the remote is in TV mode? What's the best way to disable this "feature"?

Thanks,
BGC

WAG. You assigned it in your TV upgrade? You used key move to put it on the TV mode.? Or maybe it's a learned key?

WAG?

Not assigned in TV upgrade. Not a keymove. No learned keys.

This behavior also happens if I use the builtin 0156 TV code.

I really only have to stop the play key from working while in TV mode, that would stop the vcr from coming on when I don't want it to. But, I'd still like to know why the transport keys are active in TV mode.

Thanks,

Have you thought about using the extender? That would solve your woes transport and VPT woes, BUT once you use one, you'd have a hard time going without some of the features.

I think what you're seeing is one of the built-in "punch thru" features of UEI remotes where, if the transport buttons are not defined as part of the TV setup code (and often they are not included in the TV keymap) the remote will automatically punch thru to the VCR device.

Solutions:
1. If the transport keys are part of the TV keymap in your remote, define some non-existent functions to them in your TV upgrade.
2. If they're not in the keymap, keymove some non-existent functions to the buttons in TV mode (or learn something to them).
3. Use an extender

I've peeked at the extender section a couple of times, I may experiment with those after I get this thing working.

The transport keys were not in the button map for the 881x.

Is there a way to define a null operation, all zeros for EFC OBC HEX or something like that?

I don't want to just put in some random number, the advanced code list for TV/0156 shows quite a few service menu codes and I'm afraid I might find another one by accident.

Do a key move in TV mode for something safe like Vol+.

You could keymove EFCs from a setup code that you don't use (for another TV for example).

That sounds like the way to go, all I'll have to do is the play button.

Btw, WAG = "wild assed guess"

LOL, Thanks.

I did go ahead and use a keymove in IR to set the play button to mute for a JVC tv, at least I think I did. It stopped the offending behavior anyway.

This is the keymove I added:

From Dev ---- TV
Key ----------- Play
To Dev ------- <N/A>
Device Type - TV
Setup Code -- 0053
Hex ----------- $C7
EFC ----------- 244

I also went back to the builtin code for my Tosh TV (0156) because after a closer look it had the same functions on the same buttons that I was doing in the upgrade I was making.

Thanks,
