Operating instructions
Using the camera
Attach a lens, viewfinder, microphone and any other accessories to the camera. Attach the
hybrid cable (when used) and other necessary cables to the camera. Refer to the Installation
chapter for more details.
Powering the camera
There are several ways of supplying power to the camera, depending on the system
configuration:
• by a hybrid power extender such as Grass Valley’s HPE-300 or LDK 4425 through the
hybrid cable connector (in NativeIP mode);
• by an XCU through the hybrid fiber cable and connector (in XCU mode);
• by a DC Power Supply Unit connected directly to the camera (in ‘local mode’).
The power supply for the camera is normally supplied via the hybrid fiber cable from the
base station. 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 hybrid fiber cable, an output power socket supplies +12V,
4.0 A maximum for powering accessories. The power overload indicator lights up when
maximum power is exceeded.
If excessive current flows into the camera the internal safety circuit shuts off power to all the
units. If this happens shut off power and check the units for faults and if necessary take
corrective actions before switching on power again.
When an ocular 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 power supply.
Switching on
• Switch on power on the power source (HPE-300, LDK 4425, XCU or power supply unit)
• Set the power switch of the camera to the ON position (lower back panel)
• Allow a few moments for the camera to perform a self-test and for the system to
establish communications.
To switch the camera to stand-by, set the power switch of the camera to the position.
