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 Control (SW 4 and SW 6 Models Only)

The Remote connector also provides a way to select an input to the switcher using a remote contact closure device, such as 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 (models with video) 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.

Infrared Remote Control

The optional Extron IR 102 Remote Control Kit consists of the following components:

•IR 102 switcher remote (hand-held remote control)

•IR detector with 6' cable

•IR 102 Rx receiver box with 3' cable

•External 12 VDC adapter power supply

Install and operate the remote control in accordance with IR 102 User’s Guide (part

#68-663-01) included with the remote.
