Appendix B Marquee Projectors RS-232 Control

B.1

Brief History of Marquee RS-232 Communications

Connecting an third party external controller to the RS-232 port on a Marquee projector enables
automated control of individual or multiple projectors according to custom requirements. The original
RS-232 commands enable the controller to be programmed to emulate a projector keypad. The
protocol (message structure) used for issuing these commands remains valid and usable for any
Marquee projector with software version 2.0 or higher. In addition, with software version 4.0 and
higher, you can use a simpler RS-232 protocol to issue these original commands as well as several
other new commands.

Note:

This Section is intended for technicians familiar with controller applications and programming. For
highly specialized applications beyond simple projector control, please contact VDC Display Systems
for additional technical assistance.

B.2

System Requirements and Setup

The RS-232 commands in main software V4.0 can be used with any Marquee projector that has the
Control Board #02-2x0336-0xP installed. The software is backwards compatible with existing
Marquee projectors. As shown below, connect the controller only to the “IN” port of the Marquee
projector, never directly to a switcher. Use a quality cable of up to 100 feet in length.

In a typical application, a controller output is connected to the RS-232 “IN” port, and any additional
projectors are networked by connecting the RS-232 “OUT” from one projector to the RS-232 “IN” of
the next as shown below. The controller can then broadcast to all projectors or each individual
projector as desired.
