Product Description
Speciications
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 qualiied integrators.

Installation
WARNING: This product possesses high voltage when
connected, and may present a shock hazard when the screen
cover is removed. Please disconnect power when installing
or servicing.
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. If it becomes necessary to adjust
the mechanical limit switches once the screen is installed, a
calibration procedure will be required to re-orient the SCB200
to this adjustment. Contact Da-Lite technical support for more
information on this procedure.
Each SCB200 may operate a single motor, and in the case of
multiple aspect ratio screens, which rely on multiple motors, or in
other specialized multi-screen applications, up to eight SCB200
controllers may be ganged together in a Master / Slave
coniguration for operation from a web browser or RS232
controller..
The following terminal connections are available on the SCB200:
Figure 1 - Serial / Bus / IR Connections
Terminal block 1 provides connections for RS232 controllers,
such as the optional WC- 200 wall controller, or an integrated
third-party control system. RTS / CTS connections are not
supported or required for operation. Since there are two RS232
ports on the SCB200, two independent RS232 controllers may
be used. Ports operate in the same fashion, and may be used
interchangeably. The port settings for both ports are ixed
conigurations, and used the following parameters:
Terminal block 2 provides an RS485 bus for connection
between the SCB200 devices when used in a master / slave
coniguration. When using multiple SCB200 devices, a 2-
conductor 24AWG shielded cable is connected between the SCB-
200 devices. Wire 1 is connected between RS485A and Wire 2 is
connected between RS485B.
In the event that more than two SCB200 devices are used, the
additional SCB200 devices may be connected in a daisy-chain
fashion to the other SCB200 devices.
PLEASE NOTE: When multiple SCB200 devices are used, the
RS232 ports and infrared ports on the MASTER SCB200 are
operational, and the optional NET200 may ONLY be installed
on the MASTER SCB200. Ports on SCB200 devices in SLAVE
coniguration are defeated. In this mode, all communication
originates with the MASTER SCB200 controller.

Power connections are made to the high voltage terminals
available on the SCB200. Please note that voltage must be
speciied at time of order. Improper voltage connection will
result in SCB200 damage. This termination should only
be performed by a licensed electrician.
Figure 2 - Power Connector
Installation (Continued)
The SCB200 is designed for automatic coniguration 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 conigured 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.
Coniguration
The SCB200 comes pre-conigured 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 coniguration, 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.
Mode 1 2 3 4
Master * 0 0 0
Slave 1 * 0 0 1
Slave 2 * 0 1 0
Slave 3 * 0 1 1
Slave 4 * 1 0 0
Slave 5 * 1 0 1
Slave 6 * 1 1 0
Slave 7 * 1 1 1

Installation (Continued)
Troubleshooting
The SCB200 tracks the screen’s location through a cable
connection to the B, +, A and – terminals. The cable is routed to a
small black encoder, mounted to the pin end of the screen’s
roller. The encoder shaft must turn on a 1:1 basis and rotate with
the roller pin. If the coupler wires or connector is loose the
screen may not operate or may only travel a short distance
rather than running to the complete motor limit setting.
Notes
Upon power up of the SCB200, it shall immediately begin a
diagnostic mode routine that veriies settings and prepares the
controller for operation. During this process, the following
activities shall occur:
• Load of relevant settings from EEPROM into
SCB200 memory
• Auto-detection of the presence of an optional
NET200 daughter board or slaved screens
• Initiation of the optional NET200 settings
The power up mode shall remain in efect 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 coniguration of the SCB200, the following
parameters may be set, using the RS232 protocol identiied in
Appendix A.
• Set DHCP Support *
• Set Custom Aspect Ratios
• Set IP Address *. Additional software (Lantronix and .net
framework) may be required if a static IP address is to be set
or if an invalid IP has previously been assigned. www.lantronix.
com/device-networking/utilities-tools/device-installer.html.
Xport, Device Installer under software and utilities (Please
contact Da-Lite for further assistance).
* Denotes coniguration settings related to use with optional
NET200 daughter board. Refer to the NET200 user manual
for coniguration 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. There are ive available
memory positions for custom aspect ratios.
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 center line. 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
coniguration:
• 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. From the NET200, third party control systems or
an RS232 connected computer, advanced controls and
coniguration are possible. For use of these controllers, refer
to the controller user manual for more information.

Figure 4 - IR200 Connector
WC200
When properly wired, the WC200 will have a red LED status
indicator which is always on to indicate the screen’s current state
whether stopped or moving in a particular direction or to one of
the three preset aspect ratios. Please note that the wall switch
needs a minimum of ive conductors connected to the SCB200
in order to operate. The sixth wire connection would be required
if the WC200 is to function as a switch and an IR receiver for an
optional IR200 remote. Also, the conductors will need to be the
same gage and a shield, foil braided or drain wire cannot be used
in place of a ground conductor.
WC200 controllers cannot be used on SLAVED screens and the
WC200 controller will only operate the Master screen. A ive
wire connection between the WC200 and SCB200 is required
to properly operate the screen from the wall controller. The IR
screw terminal port is not a required connection if an IR200 is
not going to be used. (Contact Da-Lite if custom stopping points
are required from the WC200 prior to order.)
NOTE: if an alternative viewing area dimension is ordered this
button runs the screen to its fully deployed position.
If programming user deinable aspect ratios or creating settings
with diferent amounts of fabric out of the screen case then
changing the setting for A6 or through RS232 commands will
change the Aspect 1 button on the wall switch. Aspect 1 button
corresponds to A6; Aspect 2 corresponds to A7 and Aspect 3 on
the WC200 corresponds to A8 in the SCB200 settings.
When using the optional WC200 wall controller with integrated
infrared receiver or third party, 12V compatible IR receiver,
connections from the infrared receiver are made to terminals 10-
12. (All six of the screw terminals will be utilized to provide full
functionality of the WC200 and the IR remote if either controller
will be used to operate the screen.)
IR200
The optional IR200 should be connected to the IR200
connection block only.
The WC200 and IR200 may not be used simultaneously.

Figure 5 - NET200 Connector
NET200
The NET200 is an optional daughter board that provides
Ethernet connection to the SCB200 and may be ordered as a
factory installed option or can be ield installed. This Ethernet
adapter allows remote control and status monitoring of a screen
or lift through a connected device. The controls available include
basic up, down and stop controls, as well as advanced controls,
such as custom aspect ratios and precise screen positioning.
The NET200 is classiied as a serial device server, which by
deinition means that it makes available to client connections the
Da-Lite screen as a serial device (enabled by the SCB200.) The
NET200 supports the full suite of bi-directional RS232
commands and acknowledgements developed under the
SCB200, and allows those commands to be issued by any
Ethernet enabled computer or computing device.
NET200 Installation
The NET200 connects directly to the SCB200 low voltage
controller at the position identiied. The NET200 will only it into
its socket in one direction; do not force the unit. When properly
installed, the Ethernet connector will be facing outward from the
SCB200.
When using multiple SCB200 controllers in Master / Slave mode,
the NET200 should only be installed on the Master SCB200.
An Ethernet cable may be directly connected to the NET200
and routed through the cable grommet in the end of the screen.
