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:
S302-1 S302-2 Color temperature

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.
8.2.3 SW303 switch
S303
output ↔ input
OFF ON
HD: 1 Xxxxx
VD: 2 xxx
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.
