Selecting an Autorun Message
Autorun causes the run mode to be entered on powerup if the DL20 was shut
off in the run mode or if a message EPROM is installed. An autorun
message can automatically be triggered when the DL20 powers up. The
autorun message is the first message displayed after self tests regardless of
the message queue or triggers. When setting up the DL20, you will see this
prompt:
The current autorun message number is displayed. You can enter a valid
message number between 1 and 1022 and press [Return]. Entering 0 disables
the autorun message.
Note: An autorun message can be chained to other messages. The chain is
repeated if the last message in the chain has auto repeat selected.
Selecting a Background Message
The background message is displayed when the message trigger queue is
empty. Background messages can be the time of day or any other message.
The prompt for the background message looks like this:
The current background message number is displayed. You can enter a valid
message number between 1 and 1022 and press [Return]. Entering 0 disables
the background message. A background message can be chained to other
messages. The messages automatically repeat until a message is triggered.
Important: The background message or the last message in a background
message chain SHOULD NOT have auto repeat enabled. Enabling auto
repeat could cause improper operation.
