1 Lens mount section
A commercial C-mount lens as well as a
Sony standard lens can be used.
2 Camera mounting reference hole
These screw holes are positioned with
high precision related to CCD sensor.

ON/OFF selector switch
7 Internal/external sync selector
switch
The camera operates with internal syn-
chronization when there is no external
sync input signal in the EXT position.
In this case, an HD/VD signal is not out-
put from the 12-pin multi-connector.
8 Trigger polarity selector switch
This switch can select the polarity (nega-
tive or positive) of a trigger pulse.
9 75 Ω termination selector switch
0 Selection DIP switch
Switches 1 to 4:
Selects the shutter speed.
Switch 5: Selects the frame or field
Switches 6 to 8:
Selects the normal shutter,
external trigger shutter, and
restart/reset.
A GAIN switch
A: Outputs a fixed-level video signal
according to the brightness of a
subject. (Variable range: 0 to 18 dB)
F: Fixed gain 0 dB
M: Variable gain (Manual)
M (during factory setting):
Adjusted so that all XC-ST50/50CEs
or XC-ST30/30CEs are the same in
sensitivity (set by Sony's standard
value) according to the deviation in
sensitivity of CCD.
Valid when multiple XC-ST50/50CEs
or XC-ST30/30CEs are used for an
identical subject.
B Volume control switch
This switch can be changed in the range
of 0 to 18 dB when the GAIN switch is set
to "M".
During factory setting, this switch is
adjusted to the fixed sensitivity for a
standard subject.
