Da-Lite's SCB-200 is a multi-position RS-232 control for electric screens. This multi-position screen control offers infinite height adjustment and multiple aspect ratio control of Da-Lite Contour®, Advantage® and Advantage® Deluxe models. For example, the SCB-200 allows the screen to "raise by four inches" or go to a different aspect ratio. This new, broader line of products is based upon RS-232 control with the SCB-200 and can be expanded to include such options as Ethernet control with the NET-200, push button wall control with the WC-200 and infrared control with the IR-200.
