External Interface
The External Interface pushbuttons (Figure 3-7) are independent
toggle on/off functions that turn editor, GPI, and peripheral bus
communication on or off.
Editor Enable
When on (lit), the [EDITOR ENABLE] button turns on
communication via all switcher serial ports configured as Editor
ports. When [EDITOR ENABLE] is off, the switcher ignores input
commands from devices connected to the serial ports.
GPI Enable
When on (lit), the [GPI ENABLE] button turns on GPI input control
of the switcher. When [GPI ENABLE] is off, the switcher ignores GPI
inputs from external devices but GPI outputs still function.
DPM Enable
When on (lit), the [DPM ENABLE] button turns on serial port
communication with an external digital picture manipulator
(DPM). When [DPM ENABLE] is off, communication with the DPM
is disabled.
