Chapter 3 Configuring the DL50 Setting Switches Figure 3.2 illustrates how to select the various functions with DIP switches. Figure 3.
Chapter 3 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.
Chapter 3 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.

Chapter 4 Installing the DL50 Wiring Recommendations Careful wire routing helps cut down on electrical noise. To reduce electrical noise, the DL50 should be connected to its own branch circuit. (See the next section for power requirements in the European Union or EFTA regions.)The input power source should be protected by a fuse or circuit breaker rated at no more than 15 Amps. Route incoming power to the DL50 by a separate path from the communication cables.
Chapter 4 Installing the DL50 Grounding Recommendations Grounding is an important safety measure in electrical installations. Grounding also helps eliminate the effects of noise due to Electromagnetic Interference (EMI). An authoritative source on grounding requirements is the National Electrical Code published by the National Fire Protection Association of Boston, Massachusetts.
Chapter 4 Installing the DL50 1. Connect ground wire to the chassis grounding terminal. Then verify that the factory installed earth ground wire is connected between the chassis PE (Protective Earth) terminal and the earth ground terminal on the power input connector. Note: If the power lines enter the left side of the display, route the AC lines through the cable guides on the upper part of the display. Route the communication lines through the cable guides on the bottom half of the display. 2.
Chapter 4 Installing the DL50 RS-232 Connections The RS-232 interface allows connection of a single DL50 display, with a maximum recommended cable length of 50 feet Figure 4.9 shows the location of the DL50’s RS-232 port terminals. The terminals are labeled: RS-232 Connection Terminals Terminal Number* Label Definition 1 T Transmit Line 2 R Receive Line 3 GND Signal Ground * Pin #1 is on top. RESET Figure 4.
Chapter 4 Installing the DL50 Figure 4.10 shows a typical connection between a host device RS-232 port and the DL50 display. The DL50 display is considered a “DTE” (Data Terminal Equipment) device. The connection diagram assumes that the RS-232 port of the host device is also a “DTE” type, as most are. If instead it is a “DCE” (Data Communications Equipment) type, you should interchange the wires on pins 2 and 3.
Chapter 4 Installing the DL50 RS-485 Connections The RS-485 interface has these advantages over the RS-232 • Improved noise immunity. • DL50 displays can be a distance of up to 4000 feet (1200 m) from the host device. • Up to 32 devices can be connected directly to the RS-485 port of the host controller. Up to 100 DL50 displays can be addressed when line drivers are used. Figure 4.11 shows the location of the DL50’s RS-485 port terminals.
Chapter 4 Installing the DL50 Figure 4.12 shows a typical connection between a host device RSĆ485 port and DL50 displays. We recommend that you use Belden 9842 cable. Note that pin or terminal numbers are not shown for the host device. This is because the terminal numbers vary for different products. For actual pin numbers, refer to the appropriate host device product literature. We recommend that you connect the shield to ground at one end only, as shown. Figure 4.
Chapter 4 Installing the DL50 Connection to DL20/DL40 “Master” Displays As previously described, a DL50 display can be connected to the RS-232 or RS-422 port of a DL20 display or the RS-485 port of a DL40 display (Master). When this type of configuration is used, all messages are stored in the Master DL20/DL40 displays. All the host controller is required to do is trigger a particular message stored in the Master DL20/DL40 display.
Chapter 4 Installing the DL50 Note: If noise problems occur between a DL20 master display and a slave DL50 display (RS-232), we recommend that you connect the shield of the communication cable to chassis ground at both ends. The earth ground for each device must be the same potential to insure that ground currents do not flow. Connect the slaves to the master using Belden 9842 cable. Figure 4.14 shows the DL40 to DL50 wiring connections. Figure 4.
Chapter 4 Installing the DL50 Connection as Slave to DL20 “Master” RS-232 Port It is also possible to use the RS-232 output of the DL20 to connect to one DL50 slave, however the distance limitation is 50 feet. These connections are shown in Figure 4.15. Figure 4.
Chapter 4 Installing the DL50 Connection to Personal Computers The DL50 display may be connected to personal computers through an RS-232 port. Either Simplex or Duplex protocol may be used in applications with a personal computer as host. • For single-point connections of 50 feet or less, the DL50 RS-232 port may be connected directly to the personal computer RS-232 port. See Figure 4.16. Figure 4.

Chapter 4 Installing the DL50 Connection to Allen-Bradley Programmable Controllers Most Allen-Bradley Programmable Logic Controllers (PLCs) provide a variety of methods to interface RS-232 or RS-485 devices. They include the: Mini PLC-2 Mini PLC-2/15, -2/05, etc. PLC-2/20 (1772-LP1, -LP2) PLC-2/30 (1772-LP3) PLC-3 PLC-3/10 PLC-5 Family SLC 500 Family The most common means of providing serial interfaces for the above Programmable Controllers include the following optional modules: BASIC Module- Catalog No.
Chapter 4 Installing the DL50 BASIC Module Catalog No. 1771-DB Catalog No. 1746-BAS The Allen-Bradley BASIC Modules (Catalog No. 1771-DB and Catalog No. 1746-BAS) provide a cost-effective and efficient serial interface to Allen-Bradley PLC and SLC controllers. The BASIC Modules store all messages in battery-backed RAM or EPROM. The modules can be programmed to transmit these messages along with status or variable data from the programmable controller.
Chapter 4 Installing the DL50 Peripheral Communications Module Catalog No. 1771-GA The Peripheral Communications Module (Catalog No. 1775-GA) is only applicable to Allen-Bradley PLC-3 Family Programmable Controllers. The module plugs directly into the PLC-3 chassis. It has several serial ports and is capable of performing many unique tasks at one time for a PLC-3 System. The Peripheral Communications Module supports RS-232 serial port specifications. Figure 4.
Chapter 4 Installing the DL50 ASCII I/O Module Catalog No. 1771-DA The ASCII I/O Module (Catalog No. 1771-DA) provides a serial interface for almost all Allen-Bradley programmable controllers. It can be plugged into any slot of a standard 1771 local or remote I/O rack. The ASCII I/O Module has no memory or programming language. All DL50 display messages would be stored in the programmable controller’s memory. Figure 4.20 shows how to connect the RS-232 port of the DL50 to a ASCII I/O Module.
Chapter 4 Installing the DL50 Flexible Interface Module Catalog No. 2760-RB Use the Flexible Interface Module with either the Catalog No. 2760-SFC1 or 2760-SFC2 cartridge with Dumb Terminal (DT) protocol.

Chapter A–B 5 Serial Communications Chapter Objectives This chapter describes how to communicate with the DL50 using a simple ASCII string format. The DL50 supports both simplex and duplex communications protocols. Each will be addressed in this chapter. Protocols Simplex Communications- In this protocol, the DL50 does not provide any responses to the master device. The DL50 receives message packets from the master device and uses this information to display text.
Chapter 5 Serial Communications Simplex Protocol The simplex data packet consists of 6 data fields as shown below: Field 1 Field 2 Optional Control ASCII Text or Special Control Byte Characters 1 Byte 0-250 Bytes Field 3 Optional Display Mode 1 Byte Field 4 Field 5 Slave Address 1 Byte Field 6 Line Number Carriage Return 1 Byte 1 Byte Note: Simplex protocol is compatible with Allen-Bradley DL20 and DL40 message displays.
Chapter 5 Serial Communications Simplex Protocol (continued) Field 3: Optional Display Mode This optional field indicates how the message text is to be displayed. If this optional byte is not present, the Line Number (field 5) determines the display mode. The following control characters are used: Table 5.
Chapter 5 Serial Communications Simplex Protocol (continued) Field 3: Optional Display Mode (continued) Special Control Characters When operating in the slave mode, the DL50 will recognize the following special control characters: • Ctrl F [FLASH] The Ctrl F (decimal 6) control character causes the DL50 to toggle between flashing and non-flashing characters. Text which is between two Ctrl F characters will flash, all other characters will be non-flashing.
Chapter 5 Serial Communications Simplex Protocol (continued) Field 4: Slave Address The slave address is a single byte field that can be any value from 1- 255, except for 6, 13,16, and 18. When connecting a DL50 to a DL20/DL40 master, the illegal decimal addresses are: 0, 4, 6, 7, 13, 16, 18, 20, 22, 43, 45, 48-57, and 128-255. A display with an address of 127 will accept all message packets regardless of the address on the packet.

Chapter 5 Serial Communications Duplex Protocol Duplex Communications- In this Protocol, the DL50 provides a response to each command it receives. The response includes data checking bytes (Checksum) and a handshake byte (ACK/NAK). The DL50 receives message packets from the master device, transmits data checksum/handshake bytes back to the master, and uses the message data to display text.
Chapter 5 Serial Communications Duplex Protocol (continued) A control byte containing Ctrl-L (decimal 12) indicates that the DL50 is being initialized for the bootstrap mode. In this mode the DL50 will be idle, waiting for the host to transmit a firmware update (refer to Chapter 7). Field 2: ASCII Text or Special Control Characters This field contains the ASCII characters (up to 250) that are to be displayed by the DL50 or sent to the message buffer.
Chapter 5 Serial Communications Duplex Protocol (continued) Field 6: Message Attributes This three byte field specifies how a message is displayed. The three bytes specify: Byte 1 Byte 2 Byte 3 Display Mode Text Height Display Speed Relay Control Reserved Display Mode / Speed The first byte of the Message Attributes field specifies display mode / display speed. The first five bits indicate display mode and the last three bits indicate the display speed.
Chapter 5 Serial Communications Duplex Protocol (continued) Field 6: Message Attributes (continued) Special Control Characters When operating in the slave mode, the DL50 will recognize the following special control characters: • Ctrl F [FLASH] The Ctrl F (decimal 6) control character causes the DL50 to toggle between flashing and non-flashing characters. Text which is between two Ctrl F characters will flash, all other characters will be non-flashing.

Chapter 5 Serial Communications Duplex Protocol (continued) Field 6: Message Attributes (continued) Third Byte Message Attributes- The third byte of the Message Attributes field is reserved for future enhancements.
Chapter 5 Serial Communications Duplex Protocol (continued) Response From the DL50 To every command the DL50 successfully receives, the DL50 will provide a response. The response packet has the following format Field 1 ACK or NAK 1 Byte Field 2 Field 3 Status Byte 1 Byte Checksum 3 Bytes 1. If the DL50 Display successfully received the message packet, and is ready to process it, the DL50 sends an acknowledge response (ACK 6 decimal). In this case, the contents of the status byte are irrelevant. 2.
