Hi all,
I recently undertook repairs on a GC-TCD,
namely the replacement of several cards, including the logic card.
After that, I encounter a communication problem between the GC and the PC.
What should be done in this situation? Is there a specific protocol to adopt or follow in this case?
Thank you in advance for your precious return,
Kind regards

The first thing I would check is if the IP address on the GC and what is listed on the Data System are the same. With the new boards it could have been set to a different value.
