The DL40 Plus address is optional if triggering a message via the
keyboard. If no DL40 Plus address is sent, the message will be
triggered on the DL40 Plus that the keyboard is plugged into. If a
DL40 Plus address is specified, the message will run only if the
address is 127 or if it matches the address of the DL40 Plus that
the keyboard is plugged into. If no DL40 Plus address is sent
when using the RS-485/RS–232 link, the message trigger will be
ignored.

If no DL40 Plus address is sent, the backslash ( \ ) is optional.

If the Remote I/O Port is inactive or faulted, the Last State switch
(number 8 on SW2) must be ON to trigger messages from the
keyboard or via the RS-485/RS–232 Port.
