3.4 Analog Audio Matrix Card Operation
The operation of the Jaguar Analog Audio Matrix Card consists of periodi-
cally monitoring the matrix card's LEDs. The matrix card LEDs and their
proper indications are discussed in the following manual sections.
Regulator Fault LED (Red)
The Regulator Fault LED (CR4) is utilized to visually indicate a regulator
problem on the matrix card. A problem with the power supply or regulator
circuits will cause this LED to light. However, in the event of a total power
outage this LED will be rendered inoperable.
CPU Fault LED (Red)
The CPU Fault LED (CR3) is utilized to visually indicate a microprocessor
problem on the matrix card. A problem with the matrix card CPU or con-
troller circuits will cause this LED to light.
Power OK LED (Green)
The Power OK LED (CR2) on the front edge of the matrix card is utilized
to visually indicate that the proper power supply voltage is being supplied
to the card. A decrease in the brightness of this LED indicates an approxi-
mate 12% drop in voltage and should be checked. A 25% drop in voltage
will cause the LED to extinguish.
3.5 Digital Audio Matrix Card Operation
The operation of the Jaguar Digital Audio Matrix consists of periodically
monitoring the matrix card 's LEDs. The matrix card LEDs and their proper
indications are discussed in the following manual sub-sections.
Regulator Fault LED (Red)
The Regulator Fault LED (CR11) is utilized to visually indicate a regulator
problem on the matrix card. A problem with the power supply or regulator
circuits will cause this LED to light. However, in the event of a total power
outage this LED will be rendered inoperable.
CPU Fault LED (Red)
The CPU Fault LED (CR10) is utilized to visually indicate a microproces-
sor problem on the matrix card. A problem with the matrix card CPU or
controller circuits will cause this LED to light.
