A 1.0Vp -p/75ohms composite video signal is provided at this connector.
4. ALC:
Used to adjust the video level when using a DD lens.
5. V-Phase:
Line lock synchronization phase adjustment. Used to adjust the phase when the synchronization select
switch 6 is set to "L/L".
6. Synchronization Mode Selector (INT, L/L):
Selects the camera synchronization mode in either internal sync mode (INT) or line-lock mode (L/L). Use
INT setting for special applications only as picture roll may be found in certain applications. It is highly

camera when powered as this may cause the camera to sustain damage.
7. Shutter Speed (AI/AES):
Selects the function of AI (shutter speed of 1/60 sec.) or AES (automatic shutter speed of 1/60 ~ 1/100000
sec.) by dipswitch settings. When using a DC drive lens, always use AI setting.
