Power connections are made to the high voltage terminals
available on the SCB-200. Please note that voltage must be
specified at time of order. Improper voltage connection will
result in SCB-200 damage.
This termination should only
be performed by a licensed electrician.

Installation (Continued)
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. A screen
must be configured to “Master” if calibration is required for the
screen. SLAVED screens cannot be calibrated through the
master screen. The WC-200 wall controller cannot recalibrate a
screen. Contact Da-Lite technical support for more information
on this procedure.
* 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. A
single Master screen will be set to 0000.
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. To change the address, DIP switches are provided on
the SCB-200. Up to eight SCB-200 devices may be ganged
together and independently addressed. Please reference the
following DIP switch table for addressing each unit.
