HDX Faceplate Indicators
Fig. 3-1: HDX Front Panel Displays
In both active and passive systems, the camera CCU needs to be powered on first and the
camera head needs to be in the ON position. In passive systems, once local power is applied
to the camera, the system should work normally. In active systems, the HDX will take a few
seconds to:
• determine what kind of equipment is attached
• safely apply the correct voltage for that equipment
LED indicators (see Figure 3-1 and the HDX LED Indicators table above) will show
diagnostic information. An Open or Shorted hybrid cable will always result in a fault
condition. The remainder of the LEDs will be Green or Out depending on what type of
camera (or Power Plus) is attached to the HDX (see the HDX LED Indicators table above).
Incoming optical power is indicated on the lower 4-segment display on the HDX. -20 dBm is
the least amount of optical power that can reliably keep the system functioning. If the CCU
is operating normally (typical optical output of approx. -7 dBm) and the HDX is showing
high loss, check your installed cable for bend radius and connector problems.
