CONNECTING POWER
The Marquee’s power input is 110-220VAC @ 50-60Hz. Three terminals are provided for connecting
operating power to the unit. These terminals are located on the Control Board (see the figure 2.2
below). Power Input terminals are labeled L1, L2, and chassis ground (8). Always connect the ground
terminal to the safety ground.
Connect the unterminated end of the AC Power Cord to L1, L2, and GND (Black or Brown to L1, White or
Blue to L2, Green or Green w. Yellow stripe to GND).

MARQUEE COMMUNICATION
2.5.1
SERIAL PORT1 (SP1) WIRING
Serial Port 1 (SP1) is pre-wired in the factory as shown below, i.e. Pins 1-2 on SP1 are jumpered
together. This jumper connects the serial port on the Message Controller board within the marquee, to
the serial port of the Message Display board in the marquee. The jumper is required for the Marquee to
display messages sent from the controller.
This port IS NOT used for PLC communication.
Except in some special cases, the user would NOT wire
anything to this port.
