TROUBLESHOOTING

GENERAL

FIXTURE DOES NOT RESET

Blown fuse: LEDs on the printed circuit board light up to indicate the power supplies are

working. Check / replace the fuses on the circuit board if one or more of the LEDs is not lit.

Sensor connection reversed: MAC 2000 will not reset properly if any of the Hall sensor

connections for the gobo wheels, gobo rotation, color wheel, effect wheel, or effect rotation

are reversed.

FIXTURE RESETS BUT DOES NOT RESPOND TO THE CONTROLLER

Incorrect XLR pin-out: The XLR pin-out is DMX standard, i.e., pin-2 (-) and pin-3 (+).

The fixture will not respond if the polarity is reversed, for example, if the MAC 2000 is

connected after a PAL 1200 without a phase-reversing cable.

Failure in the link: Diagnosing link problems is beyond the scope of this seminar. See

Recommended Practice for DMX512, A Guide for Users and Installers, by Adam

Bennette, available from PLASA, Ltd. and USITT Inc.

SOFTWARE UPLOAD

The MAC 2000 is compatible with the MP2 Uploader and the ISA DMX interface card for

the LightJockey Club controller. Version 4.0 of the Martin Software Uploader Utility is

required.

FIXTURE DOES NOT ACCEPT SOFTWARE (CSER)

Corrupted software: The MAC 2000 may not respond to the uploader if the fixture

software is corrupted. It can be forced into upload mode by moving the jumper on the

motherboard at PL 103 to the “INIT” position.

CPU write protected: The jumper at PL 102 prevents software upload when it is in the

“UPLOAD DISA.” position. Move it to “UPLOAD ENA.”, which is the factory default

position.
