NEC NC2000 Error 489

[Adam Fraser]

I have a NC2000 that is displaying error code "Security Log Warning (489)". Currently everything is working fine with the exception of the warning. I had our service company walk me through a few things on DCC, like remarrying which did not solve the issue, and said they would have to dig deeper in person to clear the logs. They will be sending a tech soon in person to look at the problem.

Circa 2012 NC2000C
Enigma Version: 1.8(24)
Server GDC SX2000A with IMB

Can this warning shut a show down mid presentation?
Would it be better to leave all equipment powered on until this gets fixed, or continue to shut down nightly like we have for the last 13 years?
Any information on this error would be appreciated, documentation is pretty sparse on this particular error.

I own the equipment and theatre, not an employee messing around with equipment.

I have DCC software and am generally familiar with it, but will leave anything that requires deeper access than DCC can provide to our tech.

I think this means that the Enigma card's log is full up. This is what the service manual says:

"Frimwarea" ?! Sounds like the name of a nasty disease that one should get vaccinated against before a trip to Africa.

If the projector appears to work normally in other respects, I think you can safely ignore this. Because you have an IMB in the upper option slot (as in, no HD-SDI connection between the media block and projector), you are not actually using the Enigma decrypter at all. The NC2000 has an Enigma card on its input board in the lower option slot, but your encrypted video is going in through the IMB in the upper option slot.

What is puzzling is how the Enigma's log filled up if it isn't being used. My guess is that it generates housekeeping log entries even when it isn't doing anything, and that is what has filled the log up. If this is right, you have two options for clearing the error if you don't feel able just to live with it.

1 - Purge the log, which can only be done from the server end. If there is no HD-SDI media block and connection to the Enigma, I'm not even sure that this would be possible.

2 - In the setup options in DCC, change the board type in the lower option slot from the model number of board that has an Enigma card on it (NC-80-somethingorother: can't remember the exact numbers), to the one that does not. There are only two to choose from, so you would change it to the other. This has the effect of telling the projector to ignore the Enigma entirely, including any error messages it may generate.

Leo,

Thank you for the information.

We have the NC-80 in one slot with nothing connected to it, along with our GDC IMB in the lower slot.

I will look in our server menu and see if there is a way to clear the logs, and try to change the slot designation for the NC-80 in DCC.

[Adam Fraser]

Switching the NC-80 in the DCC to the other type cleared the warning, and the tail lights went back to Green. Thank you for the help Leo.

I suppose even though this board has not been logging any cinelink decoding activities its probably doing some basic entry ever time its powered on. Designers probably didn't consider that one of these would be installed for 14 years without being connected to a server that would be downloading the logs. If this is powered on and off daily its likely in the 5000 cycles range now. Isn't there something like 10 512k slots on it so if a successful power up log generates a 1kb log file the math works out.

One thing I remembered overnight: I don't know for sure, but it's possible that with the "no Enigma" variant of the input board selected, the Enigma receives no power. If that's right, then eventually the battery in the Enigma will discharge, and the Enigma will be bricked.

If you're certain that you're never going to use the Enigma again, that doesn't really matter and you can let it die. But if there is any chance that you might want to, it's probably worth figuring out how to purge the logs. As an example, I look after one site with an NC3240 that has an IMS3000 in the option slot. They also have a DSS200/cat862 for emergency use if the IMS3000 breaks down. Therefore, when the IMS3000 was installed, I purged the Enigma log (a simple command line from the DSS200) and we've kept the Enigma online and married ever since.

If your SX-2000 has an HD-SDI media block in it as well as the ability to play through an IMB, it could be a little bit of a hassle (I've never done this with a GDC, only DSS and Doremi), but it might be worth getting it going, purging the Enigma log, and keeping that Enigma alive and good to go as a backup. I'm afraid that you'd need advice from someone who knows the purge procedure from a GDC to do this, though.

On the legacy board in the dcc select the one that doesnt use the enigma and it should then ignore it

[Fraser Falconer]

Yes, In setup, option Slot, swap from an NC80LB (with Enigma) to a NC80DS (without Enigma) and you'll be away laughing. Then the Enigma will die a natural death
