ECLIPSE OMEGA MATRIX INSTRUCTION MANUAL

Note: Under normal operating conditions it is not necessary to perform a full
reset. Technical personnel might perform a full restart if they believe that
the CPU card is operating incorrectly as a result of corruption of the
microproccessor’s internal data or instruction sequence.
Specific Troubleshooting Examples
The following examples describe specific problems and suggested solutions.
Problem: A port light on a port card does not illuminate, although
there is a panel attached to that port.
1. Check the panel and the wiring leading to it.
2. Check the Frame Data light. If there is no indication of matrix
communication to this card while the other cards in the matrix are
communicating, reset the card.
3. Replace the card.
4. Replace the panel.
Problem: Audio sounds low or distorted from a panel.
1. Check the matrix’s currently active CPU card’s power lights. If any of the lights
are not lit, replace the card.
2. Check the port card’s input and output gain settings in the program software.
3. Check the panel’s listen-level adjustment settings in the program software.
