period (high voltage to camera is disabled) to allow for cooling. If the internal temperature has
returned to safe operating level after this time, the output power will be re-applied. If the internal
temperature does not recover from the overheated condition, the output will remain off and the
LED will continue to flash red.
CABLE FAULT
– Lights red if the SMPTE cable: 1. Is not connected to one of the specified
cameras or APE power supply (cable open), 2. Has an internal electrical conductor broken (cable
open), or 3. Has a short between any of the internal electrical conductors (cable shorted).
The HUT-APE checks and moni
tors conditions of the SMPTE cable during both the “search” phase
and while in normal operation (high voltage output enabled). Each of the internal conductors are
monitored, the red and gray sense wires, the black and white power wires, and the ground shield.
When a fault is detected in the standby/startup mode (low voltage output), the HUT-APE will
prohibit the high voltage output from being enabled. If the system is already in normal operation and
a fault occurs, the high voltage will immediately be disabled, and the HUT-APE will protect itself
from output short conditions.
D. Fiber Plate
The fiber port connections can be installed on the front or rear panels to conveniently handle
various installation requirements. See the
Moving the Fiber Plate section for details.
E. Optical Power Meter
Two columns of 8 LEDs each form meters to display the optical power level in dBm for both the
CCU-to-Camera and the Camera-to-CCU fiber optic paths.
This example shows a good operating status. The optical power from both the CCU and camera
is at -6 dBm.
