Slave Mode Operation
Dataliner (DL) Slave mode allows multiple slave displays to display
different messages while connected to a single master device. Each
slave display is assigned an address and only displays messages sent
to that address. DL40 Plus Slaves assigned the same address display
the same messages. Messages sent to address 127 (global address) are
displayed on all slave displays regardless of their assigned address.
Note: If a DL40 Plus is used as a master display, make sure it is
configured for DL Slave protocol on it’s communication port (RS-
232 or RS-485).
DL Slave Mode is selected by DIP switch settings as described in
Chapter 2.
