Problem with repeating commands

Hi,
I am looking for some help for Vulkano device with Auxum chip.I want to control a STB which is given by a DTH provider in India.The make is Changhong and model number is CH 7900S.I have been given the remote bin file by the tech support from monsoon multimedia but I am facing problem of repeating commands with the remote.If I press the digit 1 it appears as 111 on the STB. If I press channel down once it skips 3 channels.I have tried changing the rate between fast and slow on the set up wizard but it doesn't help.
If I provide the remote bin file is it possible some one could help me to edit that file to correct the behaviour

Happy to take a look when you post it. No guarantees of course.

Unfortunately the software tools are not recognising that as a valid remote file. And the ChangHong CH 7900S is not showing up in the Logitech Harmony IR database so I can't build one from scratch. Not sure if anyone else can help ?

If nobody else can help, I may be able to. The bin file isn't decoding according to expectation for Axum, but I do recognize the setup code and the executor. So we may be able to figure out the encoding scheme.

It actually uses the standard encoding scheme. The problem was in the RDF file for Axum chip which needed a change to upper case in the signature part of the file name. Here's the revised RDF file-- the file name is the only change. This executor uses the standard IR engine so we only need to change bits 0/1 of the 7th byte of the executor to zero.

So the 7th byte should be changed from 85 to 84.

Code: Select all

43 8C 11 8B 13 85 84 10 08 06 01 A6 01 92 01 A6 01 92 A3 34 01 A6 00 00 10 04 C0 03 08 00 27 0D 03 8D 01 46

BTW, this IR protocol is a 38KHz version of RC5-7F (previously also known as Streamzap). UEI executor 0182 can shoot either a 36KHz or 57KHz version of this and this 38KHz version is apparently PID 0123.

Great stuff. Here is the revised BIN file

Any good ?
