When trying to do a re-marriage thru DCC I get a communication error(#5), although the IP addresses are correct and I seem to be able to access every other DCC function without any communication errors. Using the GDC marriage function clears the IMB marriage errors, but not the 482 & 484 errors. I can still play product but the errors are troublesome. Any insight would be appreciated.

These errors both relate back to the Enigma which you are not using and thats why you can still play back. You are using the IMB for content decryption. So it's possible the problem may be a bricked enigma. Assuming you have checked the tamper switches themselves and that you have re-seated the modules.
Are you one screen or multiple screens? If multiple screens, then I suggest swapping input modules between projectors and see if the errors follow the module. Some people run with out that module even in the projector (NC-3240 for instance), and if you do not use it for the DVI-D inputs you could shut that slot's power off.

Mark, I had wondered about the switch on the input module when re-seating. It doesn't seem like that pin sticks out quite far enough. You're right though we don't need it, doubt we ever will, so just turning the slot off was easy and took care of the problem. Thanks for the help.

There may e a round pin that sticks out at that point from the face plate to depress that switch.

If you have a bricked Enigma on an NEC input board that you don't use and don't care about, you can make the red tail light and error messages go away as follows:

- Put the projector into standby.
- Go to setup > option slot in DCC, then change the NEC input card type from NC-80LB to no card.
- Reboot the projector.
- Immediately put it into standby again.
- Change the input card type from no card to NC-80DS01.
- Reboot the projector.

The NC-80DS01 is the same board as the NC-80LB, but without the Enigma card on it. So in this configuration, the DVI and HD-SDI inputs will still work OK, but the projector will ignore the bad Enigma and give you a green tail light.

However, if you do this, I would suggest putting an "Enigma card is toast, disabled in software on Jan 11, 2019" label on the faceplate, to avoid the risk that someone will try to grab the card from it at a later date, to use in another projector.
