Introduction to the DL50
This chapter describes the basic features, functions, and operating modes of
the DL50.
The DL50 displays high visibility messages. Messages can be viewed from
up to 240 feet (73.2 meters) away. This high visibility allows messages
(fault, status, etc.) to be seen and responded to quickly.
Messages on the 2706-F11J and -F21J units are displayed in red. Messages
on 2706-F11JC and -F21JC tricolor units may be displayed in red, green or
amber, with individual character control.
The DL50 can receive message data from several sources. Messages are sent
to the DL50 in a simple ASCII format. A DL20 or DL40 display can act as a
controller, or messages can originate from a 1771-T60 Industrial Terminal
running Allen-Bradley Distributed Diagnostics and Machine Control
(DDMC) software. A DL50 can also receive message data from other
intelligent devices such as a computer or BASIC Modules
(Catalog No. 1771-DB / Catalog No. 1746-BAS).
Features
Note: Refer to
In addition, the DL50 has:
• RS-485 port for multidrop communications.
• RS-232 port for point-to-point communications.
• Relay output for turning on a lamp, audible alarm, etc.
• Anti-glare display window.
• Variety of display modes such as wiping, smooth scrolling, etc.
• Easy DIP switch configuration.
• Multiple mounting options including: Flush Mount, Back-to-Back
Mounting, and Chain Suspension. Optional mounting brackets (Catalog
No. 2706-NJ3) are also available.
• Enclosure rated for NEMA Type 12 & 13 (UL-listed) and designed but
not UL listed for Type 4 (recommended for indoor use only).
• Universal power supply accepts 100–240 VAC and 50-60 Hz.
• Firmware (in flash EPROM) can be updated using a personal computer
and Firmware Update Disk (2706-NR4).
• Fault isolation LEDs show DL50 status and aid in troubleshooting.
• Diagnostic modes help isolate faults down to a serviceable component.
• Reduced Brightness Mode prolongs the life of the display’s electronics by
reducing heat generated, thus preventing the DL50 from exceeding the
internal operating temperature limit.

Introduction to the DL50
Descriptions
➀ OVERTEMP Indicator
The LED on the upper right hand corner of the display indicates if the DL50
is in the Reduced Brightness Mode. This LED is normally off. If the
temperature inside the DL50 reaches its internal operating limit, the DL50
will enter the Reduced Brightness Mode, and this LED will begin flashing. If
the LED is on steady, the DL50 is in an automatic shutdown mode.
The ambient temperature must be reduced to continue operation.
➁ STATUS Indicators
The two LEDs at the lower right hand corner of the display indicate the
status of the display. When operating, the LEDs are on continuously. If a
hardware fault is detected, the LEDs will flash.
➂ Relay Output Connections
These connections provide both normally open and normally closed contacts.
The relay contacts are energized when a message is received which has a line
number of 48. The relay contacts are de-energized when a message is
received with a line number of 49. The relay contact terminals are labeled:

Introduction to the DL50
Operating Modes
The DL50 operates in one of three modes:
• Slave Mode. (Chapter 6)
Slave mode is the normal operating mode of the DL50. In this mode the
DL50 will accept packets of data from either the RS-232 or RS-485 port.
The DL50 supports both simplex and duplex communications.
• Diagnostic Mode. (Chapter 8)
Use this mode if the DL50 is not functioning properly. The diagnostic
mode helps isolate faults down to a serviceable component.
• Bootstrap Mode. (Chapter 7)
Use the bootstrap mode if the firmware needs to be updated to incorporate
new features. The DL50 may be reprogrammed using either the RS-232
or RS-485 communications ports. You may program multiple DL50s
simultaneously on an RS-485 network.
Reduced Brightness Mode
In addition to the three operating modes, the DL50 may enter a Reduced
Brightness Mode if the temperature inside the enclosure exceeds acceptable
limits (+167F / +75C). In this mode, the DL50 turns on the
OVERTEMP Indicator and reduces the brightness of the display LEDs. This
reduces current consumption which reduces the amount of heat generated. If
the temperature remains too high in the reduced brightness mode, the DL50
will shut down completely. In the shutdown mode, the DL50 clears the
display leaving only the OVERTEMP LED on.
If the DL50 is operated in its specified ambient temperature range and
Note:
operating conditions, the DL50 should be able to operate at full brightness.

Configuring the DL50
Selecting Slave Address
If the “slave mode” has been selected, switches S1-1 through S1-8 define an
address for the DL50 display. The values for each switch are illustrated
below. The address of the DL50 is the sum of the values for all of the
switches (1 - 8) that are turned on.
Note: SLAVE MODE is always selected for normal operation.
Slave Address
Switch Number 1 2 3 4 5 6 7 8
Value (decimal) 128 64 32 16 8 4 2 1
Addressing Example
Switch Number 1 2 3 4 5 6 7 8
Switch Position ON OFF ON OFF OFF ON ON OFF
The above example address = 128 + 32 + 4 + 2 = 166.
Note: Appendix D provides switch positions for all possible addresses.
Note: A display with a slave address of 127 (Simplex Protocol) or 255
(Duplex Protocol) will accept all messages regardless of the message
address.
Certain other slave addresses are not valid for DL50 displays when
connected as slaves to a DL20 or DL40 master. The illegal DL20/DL40
decimal addresses are: 0, 4, 6, 7, 13, 16, 18, 20, 22, 43, 45, 48-57, and
128-255.
When multiple DL50 displays are placed on one RS-485 link, more than one
DL50 can have the same address when using Simplex Protocol. DL50’s with
the same address respond to all commands addressed to them.
Note: DL50’s operating in Duplex Protocol cannot have the same address
with the exception of address 255.

Configuring the DL50
Selecting Protocol
The DL50 communicates with a host device using strings of ASCII
characters. The DL50 can communicate using one of two protocols:
• Simplex. When simplex protocol is selected, the DL50 does not provide
any response to a master device. The master sends out packets of data,
each containing message text and other information. The DL50 uses this
information to display messages.
• Duplex. When duplex protocol is selected, the DL50 responds to
messages with handshaking and checksum bytes.
Switch S2-1 selects the protocol:
