SW301
The SW301 switches (1-3) in “ON” position activates
75
Ω
termination of ext. HD and ext. VD signals and it
activates 75
Ω
termination of an ext. trigger signal.
The factory setting is “OFF” enabling TTL signal
termination for all three signals.

SW302
The SW302 switch has the following functions: The switches (1-2) determines the color
temperature, the switch (3) activates Composite sync. on the green video signal and the switch
(4) outputs the WEN signal at the DSUB connector.
The white balance is dependent on the color temperature of the light.
The available settings are shown in the below table.

The S302-3 switch adds in “ON” position the composite sync. signal to the green video signal.
The factory setting is “OFF” leaving the green RGB signal without sync. signals.
The S302-4 switch outputs in “ON” position the WEN signal via pin 7 of the 9-pin DSUB
connector. The factory setting is “OFF”. In the “OFF” position the camera outputs the
composite sync. signal via pin 7 of the 9-pin DSUB connector.
SW303
The SW303 switch switches between output of internal HD/VD
signals and input of external HD/VD signals. The factory setting
is input of external HD/VD signals (SW303-1 and SW303-2 in
“ON” position). The “ON” position is towards switch SW301.
