+12V and -12V Indicators (PSM-1)
These green LEDs are driven from the corresponding power supply output voltages and are
illuminated whenever the unit's main power is on. A dark LED when the AC or DC indicators
are on could indicate a failed power supply voltage.
4.4
Console Interface Module (CIM)
4.4.1
Features and Functions
Monitor Console TX Input Audio With Speaker And Level LEDs.
Monitor Voted Audio/Console TX Audio With Speaker.
TX/RX Audio Interface To A Console.
EIA Keying Tone Detection In Console TX Audio.
Voted Audio & Console TX Audio Level Adjustments And Measurement Points.
Adds Transmitter Keying Tones To Console Or Retransmitted Voted Audio.
Variable Delay Of Console TX Audio Prior To Transmit.
TX/RX Audio Interface With Expansion Chassis.
4.4.2
General
The Console Interface Module front panel provides a front panel speaker with volume control
(to monitor voted audio or a voted audio/console TX audio combination), and two audio
indicating levels LEDs (normal and peak) that monitor the Console TX Audio input level.
4.4.3
Speaker Switch
This switch has three selections: Off, Voted Audio, or Voted Audio plus Console TX Audio. It
controls both the front panel speaker and the “external speaker driver audio signal” available at
the rear panel. It dos not affect audio to the console or TX audio from an SVM.
4.4.4
Volume Control
This potentiometer adjusts the volume to the speaker and to the “external speaker driver audio
signal” available at the rear panel.
4.4.5
Peak & Norm LEDs
These LEDs provide a level indication for the incoming Console TX Audio into the CIM‟s
DSP and are an assist in setting the proper level via the input potentiometer R50.
4.4.6
Remote LED
The red Remote LED is illuminated when the Remote Serial Port is enabled.
4.4.7
Fault LED
The red Fault LEDs will be illuminated whenever the associated module's built-in-test circuitry
detects a fault condition.
4.4.8
Console Audio Input & Voted Output Adjustments
These potentiometers are used to adjust the TX audio level into the voter from a console (R50)
and the voted audio out to the console (R67).
