1.3.2.1 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 735mV is the
maximum signal amplitude for the respective color. The video signal is terminated with 75 ohms.
