I am having trouble installing a an M2250 console on a 7.6 CS1000 system. The console has all 5 tns wired to it. Primary, secondary and power all on the same DLC and the 5 tns are in order. It has been programmed in loads 12, and 15. When I plug the console in she lights all LCD indicators like she is going through her self test and then stays that way. All LCDs lit and locked up. I have tried two additional consoles and cables same thing. I disabled the card and reseated it, no change. Any ideas out there?
