1-2 Introduction to the DL40 Plus Slave
Operating Modes
The DL40 Plus Slave has four operating modes:
• DL Slave
• PV Slave
• Terminal
• Diagnostic
DL (Dataliner) Slave Mode
Use this mode when connecting the DL40 Plus Slave to a DL40 Plus
master display or an enhanced PanelView terminal such as the
PV1400e. One or more DL40 Plus Slaves may be connected to a
single DL40 Plus using an RS-485 link (multidrop) or an RS-232 link
(single drop only).
Each DL40 Plus Slave may be individually addressed to display only
the messages sent to a specific address. Displays with the same
address display the same messages. Addresses 13 and 18 are not
valid, see page 2-3.
PV (PanelView) Slave
Use this mode when connecting a single DL40 Plus Slave to the
printer port of a standard PanelView operator terminal (PV550, 600,
900, 1000 or 1400). The DL40 Plus Slave displays any text that
would normally be sent to a printer. The DL40 Plus Slave may be
connected to the PanelView using the RS-232 port. Only one display
may be connected on the communication link, the DL40 Plus Slave is
not individually addressable in this mode.
Terminal Mode
In this mode, the DL40 Plus Slave can receive data from any device
capable of sending serial ASCII characters. The ASCII characters
sent by the host device control the message text, line scrolling and
formatting of the messages. Only one display may be connected on
the communication link, the DL40 Plus Slave is not individually
addressable in this mode.
Diagnostic Mode
Use the diagnostic mode for basic setup and troubleshooting. In this
mode, the DL40 Plus Slave displays the hex value of all the data it
receives. An indication is provided if there is a communication error.
