User manual DA-LITE SCB-200

[. . . ] Fused protection: 5A Optional Accessories: NET-200 Ethernet Controller WC-200 Wall Controller IR-200 Infrared Sensor RM-200 Infrared Remote Control 2 Installation < WARNING: This product possesses high voltage when connected, and may present a shock hazard when the screen cover is removed. > The SCB-200 is installed as a factory option when ordering the compatible screen from Da-Lite. This is necessary because of tight integration between the SCB-200 and sensors that are used to detect the position of the screen at any time during operation. The SCB-200 is factory calibrated based on the mechanical limit switches in the screen motor. [. . . ] This termination should only be performed by a licensed electrician. 5 Configuration The SCB-200 comes pre-configured in MASTER mode, meaning that it is intended to be used without connection to other SCB-200 devices. If multiple SCB-200 are planned for use in a configuration, each must posses an independent RS-485 address. Up to eight SCB-200 devices may be ganged together and independently addressed. Please reference the following DIP switch table for addressing each unit. Mode Master Slave 1 Slave 2 Slave 3 Slave 4 Slave 5 Slave 6 Slave 7 1 * * * * * * * * 2 0 0 0 0 1 1 1 1 3 0 0 1 1 0 0 1 1 4 0 1 0 1 0 1 0 1 * Please note that DIP 1 should be in the "1" position for SCB-200 devices at each end of the daisy-chain. DIP 1 should be in the "0" position for all remaining (intermediary) SCB-200 devices. Figure 5 - Address DIP Switches The SCB-200 is designed for automatic configuration and has a factory calibrate mode that "learns" the screen's mechanical limits and stores them in non-volatile memory, so that in the event of power loss or disconnection, the calibrated settings are retained. In the event that the screen mechanical stops are adjusted or other mechanical alterations are made to the screen, the factory calibrate mode must be performed again. Contact Da-Lite technical support for more information on this procedure. Upon power up of the SCB-200, it shall immediately begin a diagnostic mode routine that verifies settings and prepares the controller for operation. During this process, the following activities shall occur: 6 - Load of relevant settings from EEPROM into SCB-200 memory Auto-detection of the presence of an optional NET-200 daughterboard Initiation of the optional NET-200 settings The power up mode shall remain in effect until each of these activities is completed. The SCB-200 will not accept or process communications with any I/O port while in this state. During the initial configuration of the SCB-200, the following parameters may be set, using the RS-232 protocol identified in Appendix A. Set DHCP Support * Set Custom Aspect Ratios Set IP Address * * Denotes configuration settings related to use with optional NET-200 daughterboard. Refer to the NET-200 user manual for configuration of these parameters. When setting custom aspect ratios, the screen is positioned in the desired position, and the position is stored to a desired custom preset memory position. When recalling aspect ratios, the SCB-200 is aware of the physical aspect ratio of the screen. Any command that requests an aspect ratio beyond the physical limitations of the screen will result in the screen being set to its lowest position. When adjusting aspect ratio, the screen is positioned according to the image centerline. Therefore, the bottom of the screen is adjusted to the proper aspect ratio position. Please note that remaining projection screen ABOVE the projected image is not eliminated when the aspect ratio is recalled. Usage To control a screen with an SCB-200 installed, at least one of the following controllers are required for operation and / or configuration: IR-200 Infrared remote control NET-200 Ethernet controller WC-200 Wall controller Third-partly control system An RS-232 connected computer There are no direct control options for the SCB-200 without one of these control mechanisms in place. From any of these control mechanisms, basic operation of the connected screen is possible.
