Video Sync Input
The V16Pro is designed to extract the vertical frame clock from an external video sync
signal. This signal should be NTSC or PAL composite video at the standard sync level of
4-volts peak-to-peak.
The V16Pro also works with "Black Burst Sync", if its level is high enough. Black burst
sync is generally well below the C-Sync level, which is approximately 1-volt peak-to-
peak. Signals at this level should not be terminated with the 75-Ohm terminator.
The sync signal is connected to the V16Pro via a rear panel BNC connector. If additional
devices are to be wired to the same sync signal, a BNC "T" connector may be used to
daisy chain the signal. If the V16Pro the only device connected or is the last device in
the chain, terminate the line by setting the "75 Ohm" rear-panel dipswitch to "on"
position. Otherwise leave it off.
SMPTE Reader/Generator
The V16Pro has a built in SMPTE read/generator. The unit will accept differential
SMPTE in and use it to synchronize the selected script. The V16Pro may be programmed
to output SMPTE to other systems. The SMPTE time code may be in following frame
rates:
23.976
24
25
29.97
30D drop format skips a frame to remain in sync with the 29.97 rate.

Power Supply
The V16Pro includes an external universal power supply that allows connection too many
domestic as well as international wall voltages (110VAC, 220VAC, 200VAC) without special
configuration. The V16Pro uses a threaded 5.5 mm barrel connector as its power input.
The DC power requirements are 12-18 VDC at 3.3 Amps
The power supply that comes with the V16Pro has the following specifications:
Input: 100-250VAC, 50-60Hz, 0.7-0.3A
Output: 18 VDC @ 3.3 Amps
