 		 #121648 - 5 bit CRC polynomial
I'm interfacing Heidenhain ROC 17 bit shaft encoder, everything is fine except that I can't get the CRC code correct to check my 17 bit position.
I contacted the manufacturer last week with no success.
Does anyone know the polynomial used for this CRC?
I tried the standard polynomial 0x15 = (x+1)(x4 + x3 + 1) and the usb polynomial 0x12 = (x5 + x2 + 1) with no success.

   what does "no success" mean?            01/01/70 00:00

         maybe we need a new 'forum' where            01/01/70 00:00

         This must be a very smart shaft encoder            01/01/70 00:00

            Yes this is what we were doing            01/01/70 00:00      
   can you find it in the pascal here? -- Kai            01/01/70 00:00

      I searched all their site            01/01/70 00:00      
         did you search the pascal code examples            01/01/70 00:00      
            Where?            01/01/70 00:00      
               I did not look at it all, but there is much here            01/01/70 00:00      
                  I downloaded them all            01/01/70 00:00      
                     what about all the .pas            01/01/70 00:00      
      Found a document name            01/01/70 00:00
