STATUS INDICATORS AND DISPLAYS
The 7707EO-3G has 3 LED Status indicators and a 4 digit alphanumeric display on the front card edge to
show operational status of the card at a glance. The card edge pushbutton is used to select various
displays on the alphanumeric display. Figure 4-1 shows the locations of the indicators, jumpers and
pushbutton.

STATUS INDICATOR LEDS
LOCAL FAULT:
This Red LED indicates poor module health and will be On during the absence of a
valid input signal, if a laser fault exists, or if a local input 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 input
signal is present, and the laser and board power are good.
VIDEO STATUS:
This LED indicates the status of the input video signal. When a valid input video
signal is detected the LED will be green. When in bypass mode the LED will be
yellow. When no video is detected on the serial video input of the 7707EO-3G the
LED will remain off.

DOT-MATRIX DISPLAY
Additional monitoring and control functions are implemented via the 4-digit dot-matrix display and controls
located at the card-edge. The card-edge pushbutton and toggle-switch are used to navigate through the
display menu. Figure 4-2 provides a quick reference to the display menu structure.
Pressing the pushbutton advances the display to the next menu level. The toggle-switch may then be used
to move up or down through selections of that menu level. Select BACK to return to the previous menu
level.
