4. STATUS INDICATORS AND DISPLAYS
The 7703BPX-DC-RF has 9 LED Status indicators on the front card edge to show operational status of
the card at a glance. The 7703BPX-DC-RF also has an alphanumeric dot matrix display, toggle switch
and push button. The card edge pushbutton and toggle switch is for user input. Figure
5-1 shows the
location of the LEDs and card edge controls.
4.1. STATUS INDICATOR LEDS
Two large LEDs on the front of the board indicate the general health of the module:
LOCAL FAULT: This Red LED indicates poor module health and will be On during the
absence of a valid RF input signal or if a board power fault exists (i.e.: a
blown fuse). The LOCAL FAULT indication can also be reported to the frame
through the FRAME STATUS jumper.
MODULE OK:
This Green LED indicates good module health. It will be On when a valid RF
input signal is present, and the board power is good.
There are seven small LEDs beside the LED display that indicate the status of the module:
CH A ACTIVE: This Green LED indicates that Channel A has power above threshold.
CH A PWR LOW:
This Red LED indicates when the received power on Channel A is below the
switching threshold set for Channel A. (See section
4.2.8)
CH B ACTIVE: This Green LED indicates that Channel B has power above threshold.
CH B PWR LOW: This Red LED indicates when the received power on Channel B is below the
switching threshold set for Channel B. (See section
4.2.8)
OUTPUT INDICATOR: This Green LED is ON when Channel A is connected to the output and OFF
when Channel B is connected to the output.
AUTO MODE: This Yellow LED is ON when Auto Mode is selected and OFF when Auto mode is not
selected.
SWITCH BACK: This Yellow LED is OFF when Switch Back Mode is selected (For auto mode
only).
