Video Signal Amplitudes:
The video inputs consist of Red, Green and Blue signals each has its own coaxial cable terminated at the monitor.
These video signals are analog levels, where 0V corresponds to black, and 700mV is the maximum signal
amplitude for the respective color. The video signal is terminated with 75 ohms.
Video Signal Termination Impedance:
The analog video signal termination shall be 75 ohm.
Synchronization (Sync) Signals:
The Horizontal Sync (HS) TTL signal is used to initiate the display of a horizontal line. HS may be either active high
or active low according to the timing. The Vertical Sync (VS) TTL signal is used to initiate the display of a new
frame. VS may be either active high or active low according to the timing.
