Thanks for the reply and info. I finally had some success Friday. Had to replace the COP SRU as well but the main problem was that Smart Rise sent us replacement boards with updated software and that had a conflict with existing boards with prior software versions. After replacing both bad SRU's, I updated the software on the existing controller SRU, checked my speed parameters and everything ran after that...no problems. Well, I also had to set the parameter in the COP board so the car call lock outs worked with the card reader, but the elevator did return to full service. I can only suggest that everyone who may work on these things should get the Debugger hardware for programming software. You will eventually need one.
