Operation
.1 Module Replacement
Should a defective Output Module or other module be found during
troubleshooting, it is best to replace the module with a spare unit. Powering
down the DMXPathfinder or at least the specific frame is recommended
before removing or inserting modules.
To replace a module, loosen its four captive Phillips screws, grasp the top
and bottom handles, and pull the module straight out of the frame. Before
inserting the replacement, set its DIP switch or rotary address switches to be
the same as the defective module's. Carefully align the circuit board into the
frame's top and bottom card guides and slide the unit in until it protrudes
about 5mm, then push the module firmly into its mating backplane
receptacles.
Before tightening the replacement's four screws, first restore power and
press the RESET pushbutton on the Master Module. This will load the
current patch file into the replacement module's crosspoint matrix. If the
entire rack was powered off, it is unnecessary to press RESET since a reset
cycle always occurs automatically on power-up.
If you forget to press the RESET pushbutton after module replacement, the
function can be initiated from the DMX-Q program at the personal computer.
