Controlling the Switcher

Controlling the System 8/10 P

LUS

 Switchers

The System 8/10 P

LUS

 Switchers can be controlled four ways:

1. Manual front panel controls (See next page.)
2. Manual, (contact closure) wired remote control
3. Manual infrared remote control
4. RS-232 control (from a host system)

Manual Remote Control

The Manual Remote connector can be used to select inputs by means of dry
momentary contact closures and Tally outputs to drive (user provided) remote
LEDs to indicate which of the inputs have been selected. This is described in
detail on page B-1 of the appendix.

RS-232 Control

The RS-232 Comm connector provides a serial interface for switching inputs by
means of a host computer (such as a PC) or other third party control system,
such as Crestron® or AMX®. For example, a control program in a PC could be
written in a DOS or Windows® environment. RS-232 programming is described
in Appendix A.
