NEC Series 2 - 4xx error

NEC Series 2 - 4xx error

This problem is caused by the TI Link Decryptor, better known as the Enigma board.  When using a projector with a "traditional" type of server (as opposed to an IMB/IMS type server), the signal coming from the external server is encrypted and decrypted by the "link decryptor" (enigma) within the projector.  The security certificate within the link decryptor is maintained by a battery that is recharged in normal use.  If the projector is left powered down for a long period of time the battery loses its charge and the certificate is lost.  This also can happen as the board ages.  After 5+ years of operation the battery may stop taking a charge.  We've seen this happen as early as 3 years.  In any case the certificate is lost and the link decryptor must be replaced.

It should be noted that if the projector is using an IMB server for digital content, the Enigma board is not being used.  The simple and free fix is to depricate the 80LBxx board into a 80DSxx board.  This turns off the Enigma module on the board and allows the board to function as a non-protected input board.  This procedure is done through the DCC.

1. Check connection between ICP PWB and Mother PWB.
2. Check connection between SIB PWB and ENIGMA PWB.
3. Check LAN Connector of Moter PWB.
4. Check LAN IP address of SIB PWB.
5. Check Frimwarea version of both SIB PWB and ENIGMA PWB.
