i got a reply from Ikegami with the proper codes.   It turns out that I should have been calculating BCC using Xor, not Or.    Now I know what the "Exclusive" part stands for in this part of the instruction:

"Exclusive OR from byte next to SOH through ETX"  

Exclusive (X) + Or   =  Xor   

I can't believe that I didnt figure that one out on my own.  But yay for quality tech support.

  

here is the proper code for CH01

CH01 01,53,31,50,81,80,30,02,43,48,30,31,03,08


I will generate the rest of the codes and post them later, just in case someone might need them someday.

thanks for the education Mark
