Round Robin Mode
In the Round Robin mode of operation you can specify both an OFF state
message and an ON state message for each input. Messages are scanned in
sequence beginning with data line D0 and ending with data line D15. If
several inputs are ON, the DL5 displays the messages in the sequence that
they are scanned. The following table lists the message numbers that are
assigned to each of the sixteen inputs.
Notice that each of the sixteen data lines listed in the table has both an ON
message number and an OFF message number assigned. You do not have to
program both an OFF and an ON message for each input. You can program
only an ON or only an OFF state message; or no message at all.
Data Line No.
ON Message No. OFF Message No.
