Some 2800 marquees have an option mechanical relay installed on the processor board. The set relay command

is used to turn this relay on or off. The relay is commonly used to operate external alarm annunciation devices

such as rotary beacon lights, strobe lights, or audible horns.

02h 41h 16h 31h

• Address Header – directs the command to the specified marquee. To send the command to a different

marquee, change the second character of the address header to the address of the marquee you wish to send

the command to. If you have disabled the addressing feature of the marquee, do not send the address header

section.

• Set Scroll – instructs the 2800 to change the rate horizontal scrolling messages traverse the marquee.

• Number – the horizontal scroll rate. Valid values range from [1] SLOW, to [9] FAST.

When the marquee displays a scrolling message, the rate at which the message travels is adjustable. Opinions

vary somewhat on what setting is best, but generally a setting in the [4] to [6] range works well. Faster speeds

can be used on wider marquees, and slower speeds should be used on shorter marquees.

Note: The scroll speed setting is stored in EEPROM memory and survives power cycling the marquee.
