Product Description
Specifications
The SCB-200 is an RS-232 enabled serial controller for
Da-Lite motorized screens. This low voltage controller features
the basic operation of up / down and stop positioning of a
screen, and when factory installed in a Da-Lite screen, is capable
of advanced operation including Da-Lite’s proprietary Da-Lite
Screen Positioning System. Da-Lite Screen Positioning System
allows for precise positioning of a standard or multiple aspect
ratio screen based on the display requirements. Instead of simple
commands such as “up”, the SCB-200 allows more sophisticated
commands, such as “go to 55 inches down”. By storing these
precise positions, a user can recall the preset by the press of
a button.
Additional detailed status information is available to determine
proper screen operation. For example, the AC current drawn
by the screen may be polled to determine if it is operating within
its normal range.
The SCB-200 is available as a factory-installed option in many
of Da-Lite’s electric screens. It is compatible with the following
Da-Lite options:
• IR-200 infrared remote control and IR receiver for wireless
operation
• NET-200 integrated Ethernet controller for network and Web
operation
• WC-200 intelligent wall controller with IR receiver for in-room
operation
The SCB-200 is also compatible with many RS-232 enabled
control systems for integrated system control. A complete
command protocol is supplied in Appendix A for reference
by qualified integrators.
