I have to program a T2 to control a Krell DVD Standard which uses an RC-5 codeset. The T2 refuses to learn the RC5's.

Pronto learns the codes fine, and even trying to learn the codes from the Proto have failed.

Any tricks on getting the T2 to work with RC-5?

Is there a IR library convertion program that will take the CCF and Create an RTI IR File?

Try learning the commands into a low end learning remote and then into the RTI. Your trying to get a "dirty" code on purpose. My favorite remote for this is the old Xantech URC-1.

I have two ARCAM remotes that use RC-5 codes and the RTI has been able to learn all of the remote's functions directly. (And the RTI signals are recieved at the component better than their own remotes!) However, ARCAM has made available some discreet on/off codes in RC-5 format that the components will sense, but the remotes don't have. How do I get these codes into the RTI? I don't have access to a Pronto or Marantz remote.

Thanks,

OK, if I could get a Yamaha RAV2000, would that work?

An RC-5 protocol remote has two different versions of each command and alternates between them on repeated presses of the same key. When you learn the function, you only learn one of the two versions. If you press the key for that learned function twice quickly, a properly designed RC-5 receiver will not believe you pressed it twice quickly, instead it will think you pressed it once slowly. On the orriginal remote, pressing twice quickly sends both versions, so the receiver can be sure you pressed twice quickly, not once slowly.

If you never noticed that problem, maybe you never press the same key twice quickly; Maybe you only did it with keys like vol+ where twice quickly should do the same thing as once slowly (rather than keys like digits where twice quickly is usually different from once slowly); Maybe your device's receiver is strange and doesn't follow the RC5 rules properly.


You can paste Pronto hex into the RTI software. (Subject to the learning problem above) Pronto hex for RC-5 in the "0000 006C 0000..." format works. I don't think Pronto Hex in the "5000..." format works, but I'm not sure. There are tools available to create the "0000 006C 0000..." form from the 5000 form or from the system and command numbers.

To get around the problem of not being able to use the same command twice in a row, some people have managed to get dirty enough signals that each valid command is followed by garbage enough to restart the receiver's logic and let it see the same command the next time. Others have discovered null-operation commands and hand edited Proto Hex to tack a null command on the end of each real command so the receiver never sees the same command twice in a row.
