Windows-Based Program Control

The Universal Switcher Control Program, part #29-031-01, is compatible with Windows 3.1/3.11, Windows 95/98, Windows NT, Windows ME, and Windows 2000 and provides remote control of the following:

•Input selection (including audio breakaway for models with video and audio)

•Audio gain and attenuation adjustments (audio models)

•Front panel switch mode selection (auto-switching models)

Updates to this program can be downloaded from the Extron Web site (http://www.extron.com).

Installing the software

The program is contained on a single 3.5” diskette and can be run from the floppy drive, or it can be installed and run from the hard drive.

To install the software on the hard drive, run setup.exe from the floppy disk and follow the screen instructions.

By default, the Windows installation creates a C:\UNIVSW folder and places two icons (Universal Switcher Control Program and Universal Switcher Help) into a group named “Extron Electronics”.

Using the software

1.	To run the software, double click on the Universal
	Switcher Control Program icon in the Extron
	Electronics program group.
	2.	Click on the comm port that is connected to
		the switcher’s RS-232 port.
	3.	The Extron Universal Switcher Control
		Program window (Figure 4-2) displays the
		selected input, the audio gain for the selected
		input, and the panel mode.

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 Signal Enhancement Products 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 Remote Control

The Remote connector also provides a way to select an input to the switcher using a remote contact closure 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.

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.
