4.9.2 Powering the camera
The power supply for the camera and its adapter is normally supplied via the Triax or hybrid
fiber cable from the XCU. The Power On indicator lights when power is supplied and the
camera power switch is set to the on position
.
When power is supplied via the Triax or hybrid fiber cable, an output power socket supplies
+12 VDC, 1.5 A maximum for powering accessories.
If excessive current flows in the camera or adapter, the circuit breaker trips and shuts off
power to all the units. If this happens check the units for faults and if necessary take corrective
actions before pressing the circuit breaker button to reset the power.
When an eyepiece viewfinder is used the BATT indicator in the viewfinder lights if the camera
supply voltage is less than 11.5 VDC when using an external supply.
Tip
✎
It is also possible to operate the camera without a Triax or hybrid fiber cable by supplying a
+12 VDC supply to the DC input socket.
4.9.3 Selecting monitoring signals
Viewfinder display signal
The viewfinder can display local (from the camera) or external (from the XCU) video. Two toggle
switches at the back of the adapter determine the signal that is displayed in the viewfinder.
