Basic Functions
Synchronization methods
Internal and external synchronization are available;
VISCA Commands allow you to switch between them.
• Internal synchronization
An internal vibrator inside the camera generates a
synchronizing signal as a basic oscillator.
NTSC=59.94 Hz
PAL=50 Hz
• External synchronization (V-Lock Synchronization
1)
)
When a TTL level V-Lock pulse is input, the camera
synchronizes to the input signal (V-lock
synchronization). The frequency of the input signal
synchronizes to within ±1Hz of the external
synchronization.
Also, 360 degree phase adjustment is possible due to
the phase adjustment of the V-lock signal.
When adjusting V-Phase, first make the phase
adjustment with the Line Lock mode, then switch to
Frequency Lock mode and enable external sync. If
not performing phase adjustment, switch to
Frequency Lock mode then enable external sync. See
“Command List” on page 31.
Note
Noise may occur when performing phase adjustment
with the Line Lock mode, although it should
disappear when switching to Frequency Lock mode
for external sync.
Because V-lock synchronization is a simple synchronization
method, color signals like a VBS “Genlock” signal cannot be
synchronized.
1)In V-lock synchronization, the camera makes a V-lock pulse
(VL-PULSE) which synchronizes to the commercial power
supply and uses it as the external synchronization input signal
of the camera, using the fact that the V cycle (59.97 Hz vertical
synchronization signal) and the frequency of the commercial
power supply (60 Hz). The synchronous signal of the camera
will automatically sychronizes to the VL-PULSE in the
camera.
FocusTrace: 54
When zoom speed is given priority, using the
ZoomDirect command changes focus at high speed
(although the image may be blurred because focus
is not tracked). For example, the focus transition
time from Wide to Tele ends, which typically takes
2.8 seconds, can be reduced to 2 seconds.
FocusOffset: 55
Placing a dome cover in front of the camera may
cause the focal distance of the camera to change.
Especially at the Tele end, this effect exceeds the
AF range, so focus cannot track, although it
responds to changes in this value.

Title Display
•You can set a title composed of up to 11 lines. One
line can contain up to 20 characters.
•You can set display on/off, the horizontal position of
the first character, blinking state and color for each
line.
• The camera gives priority to lines of a title when the
camera status is displayed on the relevant line. On the
lines where a title is not set, the camera status is
displayed.

H-position 00 to 17
