4.12.1 Powering the camera
The power supply for the camera and Triax adapter is normally supplied via the triax
cable from the Base Station. The power on indicator (6) lights when power is supplied
and the camera power switch is On.
If excessive current flows in the camera or adapter, the circuit breaker (7) trips and
shuts off power to all the units. If this happens check the units for faults and if
necessary take corrective action before pressing the circuit breaker button to reset the
power.
It is also possible to operate the camera without a triax cable by supplying a +12 Vdc
supply to the DC input socket.
When power is supplied via the triax cable, an output power socket su12 Vdc,
1.5A maximum for powering accessories.
4.12.2 Selecting monitoring signals
Viewfinder display signal
The viewfinder can display local or external video signals. Two switches (11) determine
the signal that is displayed in the viewfinder.
Set the first switch to LOC to display the local camera Y signal in the viewfinder. (The
Ret. button on the lens also selects this signal in parallel with this switch.) If set to the
other position, then the second switch determines the signal displayed in the
viewfinder.
The second switch selects the signal displayed in the viewfinder when the viewfinder
signal selection switch is not in the LOC position. The signal then displayed is:
• EXT Base Station external input 1 or 2.
• MIX Base Station external input 1 or 2 and camera Y signal mixed.
External signal selection
The External signal selection switch (9) selects either the EXT1 or EXT 2 signal from
the Base Station.
In addition to this switch, other switches on the camera (VTR start) can be set up in the
Install menu to switch this function.
Output monitoring signal
The monitoring output selection switch (10) determines whether the viewfinder signal
from the camera or the external video signal from the Base Station is available at the
output connector .
4.12.3 Using audio
Two high quality audio channels are available in the triax mode. Set the gain levels (-22
to -64 dB) for these channels in the Audio section of the Install menu. A high-pass filter
for each channel can also be switched on via this menu.
