Dataliner (DL) Slave Mode
Chapter Objectives This chapter describes the operation of the DL5 Slave in DL Slave Mode
and contains the following topics:
• Slave mode description
• Slave mode protocol
• Example messages
• Display options
• Clearing one or more lines
Slave Mode Operation DL Slave Mode is selected through the configuration menu as described in
Chapter 3. Dataliner (DL) Slave mode allows one or more DL5 Slaves to
display different messages while connected to a single master device such
as a DL40 Plus master display.
Important: If you are using a DL40 Plus as the master, configure its
communication port for DL Slaves (refer to the DL40 Plus user manual,
Publication 2706-6.1). This configures the DL40 master to send message
data in the DL Slave format.
In DL Slave Mode, the DL5 Slave accepts messages in the format:
16 Characters to Display

126 (20hex to 7Ehex) are supported. Any valid ASCII character, upper or
lower case can be sent however, lowercase letters are displayed as
uppercase. All control characters within the message text field, except
[Ctrl][F] and [Ctrl][R], are ignored. If fewer than 16 characters are sent, the
remaining character positions are filled with spaces. Appendix B shows
the DL5 Slave character set.
