I purchased an RCA audio/video switching unit (Model: VH915) with a remote control. It has 4 inputs and 1 output with composite/s-video and analog audio jacks. It came with a small peanut shaped remote control. The remote had 4 buttons for the inputs (labled, of course, 1-4) another button that said "scan" and I believe there may have been another button that was similar to a "previous input" button.

Anyways, I only actually need the IR codes for inputs 1 through 4. I'm programming a Pronto TSU2000 so I can use either a .ccf file or just the plain hex codes. Either way, I would be extremely greatful! Thanks.

Out of curiousity, did you try this?

I'm downloading it now, so I'll definitely check it out and see. Thanks for informing me of it, I'll let you know if it works.

Well, I gave it a shot, but no dice. It appeared that a few of the codes where for a television. It just so happens that the system I'm programming this for has a Proscan television (which is owned by Thompson who also owns RCA) and the button labled "CPU" is also the IR code for Input 1 of a Proscan television. Who knew? Thanks for the suggestion, though!

I think the VH920 comes without a remote of its own and can learn signals from other remotes for its input select. But it's fairly bad at that task.

Someone figured out it has a default set of command that it falls back on when it has no learned commands. At first glance those look like the ones in that CCF file, but I haven't checked carefully.

I do recall that the default commands for a vh920 are mainly the RCA generic discrete on commands for various other devices. That "CPU" command is the discrete on for some RCA VCR. Some other RCA device (such as your TV) also use the RCA VCR discrete on command as an input select (for the input on which they hope you connected an RCA VCR).

Obviously, the hope that the VH915 used the same commands as VH920 was meaningful only if that CCF for the 920 had the default commands rather than learned commands. Only the "echo", "vcr" and "cpu" commands in that set of 920 commands are RCA discrete on commands. The other four are all RCA discrete off commands, which doesn't match my partial recall of the 920's default commands.

It turns out I had the VH915 command set after all. Somehow I missed on the first time I checked. In condensed Pronto hex, the four digit buttons are:

900A 006D 0000 0001 00FF 14EB

900A 006D 0000 0001 00FF 04FB

900A 006D 0000 0001 00FF 18E7

900A 006D 0000 0001 00FF 00FF

The other three commands (I'm not sure of meaning) are:

900A 006D 0000 0001 00FF 08F7

900A 006D 0000 0001 00FF 0CF3

900A 006D 0000 0001 00FF 10EF

And these are all non RCA IR signals that have no relation to the VH920 or other RCA products (I wonder if RCA rebranded someone else's product to make the VH915).

Could you post or email me the .ccf file for the RCA VH915 selector if you have it? My MX850 remote can read a pronto .ccf file.

Thanks,

Is there any reason you did not simply teach the IR codes to the Pronto? I keep seeing posts(for years) where this simple solution is not utilised.

Shoe, my mx-850 remote is suppose to arrive today so I have been playing around with the MX-Editor writing my program ahead of time. I don't expect the remote to work write off the bat after downloading the program I created but I wanted to reduce the amount of playing around with delays and learning buttons if the codes already exist. I have the original remotes for all of my components so learning the IR codes should not be a problem. I just was having so much fun working with the editor as I wait on my remote.
