911 guys.. Have a duplex unit with single "swing panel" controlling both units. Wired rope gripper control panels in and installed new relay boards from mce. They sent a new U9 chip which was installed and both units went nuts. Push car call 5 and car would go to 2 for example. Put old U9 chip back in and elev. 1 works fine. Elev 2 still has " stepping issues" 10 stops on both units. Elev. 2 will run from LL to 5 fine if I put a 6,7,8,9 floor call in unit will go to top floor slow down and hit top normal limit. We think that swapping the EEPROM chips around we need to readdress the floor designations?? Are we on the right track......thanks for any help
