The DL40 Message Display offers a number of operating modes from which
to choose. Each provides you with the tools you need to perform a different
set of functions. The following paragraphs and the tables that accompany
them provide a brief overview of the various operating mode options
available to you.
Run Mode
Run Mode is the normal operating mode for the DL40. In Run Mode
messages are triggered for display on the DL40 and (if desired) on slave
message displays.
The Remote I/O version of the DL40 always comes up in the Run Mode after
reset. The Parallel Port version does, too, except when the message display’s
Run Mode/Debug DIP switch is set to Debug .
