Installation and Operating Instructions For
SERIAL CONTROL BOARD SCB-100
INSTALLATION
This manual covers installation for both the external SCB-100 and the built-in SCB-100. If you have the external SCB -100,
refer to diagrams 1, 2 and 3 for wire connections. If your screen has the SCB-100 built into the screen case, refer to
diagram 4 for wire connections.
The main power wires (100-240VAC) should always be separated from the low voltage wires. To do this, route the power
and motor wires into the housing using the knockouts on one end of the housing. The wall switch and RS-232 wires
should be routed through the knockouts on the opposite end of the housing.
Do not connect power to the SCB-100 until all other connections are complete.
Wall Switch
The SCB-100 has two manual switch ports. These ports are for dry contact closure only. Port 1 controls motor 1. Port 2
controls motor 2.
1. Install wall switch where desired.
2. Use 3-conductor 20-24 gauge wire to extend the switch wire to the required length.
3. Connect the wall switch to the SCB-100 as shown in diagram 1.
CAUTION: Never apply voltage to the wall switch terminal or the unit will be damaged.
RS-232
The SCB-100 has two RS-232 ports. Port 1 and Port 2 can control either motor 1 or 2.
Both ports are marked with RX, G, TX.
RX-data being received into the SCB-100.
TX-data going out of the SCB-100.
G-ground.
12VDC Out
The SCB-100 supplies voltage to the optional NET-100 network adaptor. The center terminal is not used.

Screen Motor
The SCB-100 has two motor outputs. This allows control of two screens or a screen and a projector lift independently.
1. Connect the motor wires in the screen junction box to the SCB-100 as shown in diagram 2.
2. Use 14-18 gauge wire to extend the motor wire to the required length.
Power Source
1. Connect power wires to the SCB-100 as shown in diagram 3.
2. Connect the building ground wire to the ground lug on the metal housing.

RS-232 Communications
The command protocols are as follows.
Screen 1 up: @1U
Screen 1 stop: @1S
Screen 1 down: @1D
Screen 2 up: @2U
Screen 2 stop: @2S
Screen 2 down: @2D
Poll: @P
Response to a poll is @1x2x where x is U for up, S for stop, D for down.
Communications is 9600 baud, 8 data bits, No parity, 1 stop bit.
No “Return” or “Enter” is required at end of string. The command will be executed as soon as the U, D, or S is received.
There is a 50ms time out if a valid character is received but the string is not finished. All command characters must be
sent in one packet.
Built-In SCB-100 Control
Locate the 11-pin connector in the junction box of the screen. Refer to diagram 4 for wire connections.
RS-232 Ports
The SCB-100 has two RS-232 ports. Both ports have three wire connections.
RX-Data being received into the SCB-100.
TX-Data going out of the SCB-100.
G-Ground.
Wall Switch
The wall switch terminal is a dry contact closure. Do not apply voltage to this terminal or the control will be damaged.
1. Install the wall switch where desired.
2. Use 3-conductor 20-24 gauge wire to extend the switch wire to the required length.
12VDC Out
The SCB-100 supplies power to the optional NET-100 network adaptor. If you are using the NET-100 adaptor, connect the
power wire from the NET-100 to the 12VDC output terminal.
