1. Connect a serial cable between a PC and the switcher’s Remote port. The
cable’s pin assignments are shown in figure 4-1 on page 4-2. Power up the PC
and the switcher.

Universal Switcher Control Pgm.
3. Click on the COM port that is connected to the switcher’s RS-232
port.

Using the help system
For information about program features, you can access the help program in any of
the following ways:
• From the Extron Electronics program group, double-click on the
Universal Switcher Control Program Help icon.
• From within the Windows-based switcher control program, click on the Help
entry on the task bar.
• From within the Windows-based switcher control program, press the F1 key.
Contact Closure
The Remote connector also provides a way to select an input to the switcher by
using a remote contact closure device, such an Extron KP 6 Keypad Remote Control
or a locally-built device. Contact closure control uses pins on the Remote connector
that are not used by the RS-232 interface. The contact closure pin assignments are
shown in the table on page 4-2.
Autoswitching models must be in normal (manual) mode.
To select a different input number using a contact closure device, momentarily
short the pin for the desired input number to logic ground (pin 5). To force one of
the inputs to be always selected, leave the short to logic ground in place. The short
overrides front panel input selections.
