HSYNC Horizontal synchronisation output (HSYNC)

VR Vertical reset input (TTL level)
A vertical image synchronisation can be made with a vertical
sync signal
GENLOCK External synchronisation
Input to synchronise the camera to an external video device.
A video signal (75
Ω
) or a TTL signal, consisting of horizontal
and vertical synchronize pulses (composite sync, CSYNC) is
needed.
The synchronisation is achieved by an internal PPL.
A second possibility is to input separately the horizontal sync
and the vertical sync. In this case the horizontal sync must be
connected to the GENLOCK and the vertical sync must be con-
nected to the vertical reset (VR).
The synchronisation with Genlock can be enabled/disabled by
controlling LSW. This can be done with DIP switch S1:
DIP switch S1/pin 8 = open Genlock disabled
DIP switch S1/pin 8 = closed Genlock enabled
