SW USB Series • Introduction

PRELIMINARY

Contact closure control — Connecting a push-button contact closure device to

the SW USB’s Contact port or shorting pin 1, 2, 3, or 4 to the ground (

)

pin of the Contact port provides an alternative method of input selection

on the SW USB. Commands issued via contact closure can also be passed

through the RS-232 Pass Thru port to an attached RS-232 controllable Extron

switcher. See “Contact Closure Control”, in chapter 2, “Installation”, for

more information.

Hot key switching — (SW4 USB Plus only) When host emulation is enabled, inputs

can be selected by a combination of key presses on a keyboard connected to

port 3 or 4.

Front panel security lockout (executive mode) — To prevent unauthorized access

to the switchers, executive mode can be enabled via the front panel or SIS

commands to disable all front panel controls.

Port status LEDs — The Active USB LEDs provide visual indication of port status/

activity for USB peripherals and all connected and active host devices.
