2800 Series Marquee

1.15 Enabling Message Scrolling (SW2)

When the PC/PLC control system commands the 2800 marquee to display a message that is too long to fit on the

LED display, the marquee can be configured to automatically scroll the text horizontally, or to truncate the

message as required to make it fit on the display.

To disable message scrolling, set switch 4 on the SW2 dip switch block to the OFF or OPEN position. The

marquee will truncate messages as required to make them fit on the LED display.

To enable message scrolling, set switch 4 on the SW2 dip switch block to the ON position. The marquee will

automatically scroll any messages that are too large to fit on the LED display.

1.16 Setting the LED Display Width (SW2)

2800 series marquees can be purchased with one, two, or three display boards of width. The AB-2476-020

processor board needs to know how many display boards are present so that it may properly position and scroll

message text as required. The proper display width is configured at the factory before the 2800 marquee is

shipped, but we cover how to set it here for the sake of documentation completeness.

The easiest way to determine the number of display boards in your marquee is to measure the width of the LED

grid. Each LED display board is two feet wide so 1 Board = 2 Feet, 2 Board = 4 Feet, and 3 Board = 6 Feet of

LED display width.

OFF OFF 1 10

OFF ON 2 20

ON OFF 3 30

ON ON 3* 30*

* = This setting may be changed in future revisions of the firmware.

1.17 Setting the Unused Switches (SW2)

Switches 7 and 8 on the SW2 dip switch block are reserved for future feature set expansion of the 2800 series

marquees. Please set both to the OFF position.
