Monitor Interface

Contrast Control
Potential Balancing
Use the controls on the monitor to set the appropriate brightness and contrast.
The switch for the terminal resistor may only be switched to "High" if another operator panel
or another monitor is connected via the "OUT" BAS socket. For operation without continued
looping of the monitor signal, set the switch to "75E".
The 24V output is for voltage supply of the keyboard encoder only.
Running the monitor at full contrast reduces the CRT's useful life.
