7 DIP switch Ⅲ Video synchronization selector switch Switches the synchronization method of the camera image. INT: Internal synchronization L/L: The camera's vertical synchronization is matched with the frequency of the AC 24 V line power supply. When switching between multiple cameras using a switcher, selecting the LL mode and adjusting the vertical phase can reduce the monitor sync disturbances occurring when the camera image is switched. Ⅲ Control signal termination ON/OFF switch This is a termination ON/OFF switch between the "RX+" and "RX-" control signal connection terminals. ON: The "RX+" to "RX-" route is terminated by a 110-Ω resistor. OFF: The RX+ to RX- route is not terminated. 9

DIP switch
±
Video synchronization selector
switch
Switches the synchronization method of
the camera image.
INT:
Internal synchronization
L/L:
The camera
’
s vertical synchroniza-
tion is matched with the frequency
of the AC 24 V line power supply.
When switching between multiple cam-
eras using a switcher, selecting the LL
mode and adjusting the vertical phase
can reduce the monitor sync distur-
bances occurring when the camera im-
age is switched.
±
Control signal termination ON/OFF
switch
This is a termination ON/OFF switch
between the
“
RX+
”
and
“
RX
–”
control
signal connection terminals.
ON:
The
“
RX+
”
to
“
RX
–”
route is
terminated by a 110-
Ω
resistor.
OFF: The
RX+
to
RX
–
route is not
terminated.
