7. 6 External Sync

When using the unit with an external sync signal, input HD and VD to CC3 and CC4 of the DIGITAL terminal. When the external sync signal is input, the camera automatically switches its sync from the internal sync to the external sync.

The operation is as shown below, depending on the unit's status and how external sync signals are input.

( 3 ) Using the unit with external sync signal

When adjusting H (horizontal) phase refer to the item "7.2 (5) (5.1) Adjusting horizontal phase".

(3. 1) H (horizontal) phase adjustment

Observe the external sync signal and the LVAL signal output waveform of the unit with a dual trace oscilloscope, and ad- just H phase so that the H phases match.
