CV-M77
The SW301 switches (1-3) in “ON” position activates 75Ω termination of ext.HD and ext.VD signals and it activates 75Ω termination of an ext.trigger signal. The factory setting is “OFF” enabling TTL signal termination for all three signals.
8.2.2SW302 switch S302
OFF ON
White - 1
Balance 2
Sync. on G: 3
WEN: 4
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 |
OFF | OFF | 2800-5600K (factory setting) |
OFF | ON | Invalid setting |
ON | OFF | 4600K |
ON | ON | 5600K |
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.
8.2.3SW303 switch
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.
