Only testing we did was to make sure we had the same voltage at the loop wire than the schematic. At first our loop wire wasn't good. as soon we changed it, it worked.

Yes, I will try to take pictures of it as soon as I can. The only thing we did was follow the part list, place all components at its place, make sure all errata items were coverred and thats it.

I did the same as you many many times, i get the same voltage. So perhaps it is my wire.

Here is the data format for anyone who would like to write PC software to accept the Cano decoder:

Each message consists of 16 bytes: The first 6 bytes are ASCII hexadecimal characters representing the first 24 bits of each transponder transmission after the preamble, which we will use for the transponder ID. The next 8 ASCII hexadecimal characters are the timestamp, MSB first, in increments of 1/4 millisecond. (Zero time is when the decoder was powered-up.) The string is terminated with a carriage return and line feed. Here is a typical example:
next 8 bytes are timestamp
are the final two to make it 16 bytes CR-LF ("\r\n")?

The RCM software can read the decoder via a network interface. The P3 protocol I believe. The Cano decoder does not support this, but would it be possible to create a computer program that reads the decoder input from serial and convert it to P3 protocol packages and deliver that to a server, just as you set up an AMB rc3 decoder to do for instance? And to be complete the computer could even duplicate the P3 protocol on serial out as well.
If that is possible then we would have the same R/C software compatibility as the AMB decoder itself.
Possible or not?

I added Cano support in an evening but I had to refactor my code before that to unmarry my code from p3.

Btw, anobody that has some printed circuit boards extra?

I would guess that RCM would like a physical device in order to test their implementation. How else can they verify and guarantee that RCM will work 100% with the Cano decoder? And to optain or build a device is not that easy...

I don't have a cano device either, but the spec is very straight forward so I just added an implementation that *should* work and released it without guarantees. I posted the C# source code for ourlaps cano plugin, which can be used any way anyone sees fit.
Howard provided me with sample decoder data when I asked him. It may even have been posted in this thread already? idunno.

The decoder data is very simple. This post has a complete description:

The data below is what I sent to Torg. It is for one transponder, with laps of about 4 seconds.
The first line is a power-up message (which now also says "REV B"). All other lines are as described in the post given above.
