Input and Output Configuration
The on-screen display menu and the serial ports can be used
to configure the unit's input and output signals. "Front panel
menu controls" later in this chapter has instructions on using the
front panel menu. Chapter 4 has instructions for SIS commands
to the unit.

signal are defined. The active area is the image seen on the

additional information that allows the display device to position
the image.
