Samaung DVD-HR735 have unknown protocol

Rafa · Post by **Rafa** » Wed Sep 19, 2007 10:00 am

I was making a "device update" for the remote of my Samsung DVD-HR735, because there was any code working, and the memory is not enough to handle all the buttons.
I got on ALL learned signals something like:
Gap-468-1477-16? 32 0
Gap-468-3461-37? 0 0 0
and without EFCs or HexCmd.
I've tryed to learn them again, change the batteries, etc... and nothing, it seams the protocol is really missing.
Does anyone know how to overpass this issue?
Are there any updates to the IR705 or to RemoteMaster1.81 that handle these protocols?

I uploaded the "ir" file with the learned signals for diagnostic to:

My remote is the: URC-7555 OFA5 (One For All 5)

These signals look the same as those described here:

Those signals are for a Samsung DVD-HR725, so my guess is that they'll also work for your DVD-HR735. However, this upgrade uses a custom protocol that was written for S3C8 remotes, whereas you have an HCS08 remote, so somebody would need to convert the protocol to that format.

Try this:
Upgrade protocol 0 = 01 5C (HCS08) Samsung DVD HR725 (PB v4.00)
20 19 22 48 41 8F 45 05 08 00 FA 02 DF 00 FA 00
FA 77 61 08 CA 08 CA 00 00 00 11 3C AA 4E 64 65
33 65 CC FF 7A
End

Well... sorry... but now what?

What to to with this protocol upgrade?
I can put it in the Protocol tab of IR and than what do I do?

Sorry, this may be a "basic question", but I'm new at this, and tried to play around, but I didn't figure out the next steps...

And how to use this information in RM?

Thanks!!
