2800 Series Marquee

3.1.8 Load Mode [CTRL-L]

Address Header Load

Mode

CTRL-B A CTRL-L

• 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.

• Load Mode – instructs the marquee to prepare for high speed message programming.

This command is used by American LED-gible utility software, such as the Magic Message Generator II program,

to prepare the marquee to receive high speed message programming. In response to this command, the

marquee temporarily shuts down most of the background tasks in order to free up CPU time. The background

tasks are restarted when the marquee receives a reset command.

3.1.9 Disable Queuing [CTRL-O]

Address Header Disable

Queue

CTRL-B A CTRL-O

02h 41h 0Fh

• 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.

• Disable Queue – instructs the 2800 to reset, and then disable the message queuing feature.

Disabling the message queue modifies the 2800 message recall behavior. When message queuing is enabled,

the marquee maintains a queue of recalled messages and automatically displays all of them in a round robin

fashion. When message queuing is disabled, each time a message is recalled, any previously recalled messages

are cleared. For more information on enabling message queuing, see manual section 3.1.15.

Note: The queue enabled/disabled setting is stored in EEPROM memory and survives power cycling the

marquee. However, the message queue is stored in RAM and is cleared when power is lost or the marquee

reboots.
