Hi Guys,
Have this issue on my carrier 30hxc230 about scpm card. I have an old faulty card with detail CEBD430416-12A printed on it and we order a replacement which arrived with card number CEBD430416-13 RA. I have made changes on the DIP switches as per the old card and I can't have a communication with the main board. The only difference I saw was on the last code of the boards which were 12A from the old card and 13-RA on the new card. Any help will be appreciated so much as we are badly needing the unit to run

Thank you guys.
