Downloading Match Codes via DH485 Protocol with an SLC 5/03 or SLC 5/04 Controller

Overview

Hardware Requirements

This application describes how to download match codes to the bar code reader from an SLC 5/03 or SLC 5/04 controller using DH485 protocol in master and slave modes.

DH485 Master is used for bar code data traveling at medium or slow speeds. Data is sent to the SLC 5/03 or SLC 5/04 controller whether it was requested or not by the SLC 5/03 or SLC 5/04 controller.

DH485 Slave is used for bar code data traveling at high speeds. The SLC 5/03 or SLC 5/04 controller initiates the request for bar code data.

Refer to chapter 3 for a listing of additional host commands and response codes.

The hardware items required for this application are:

• 2755-SN3, -SN5, or -SN8 AdaptaScan Bar Code Reader

• 2755-PW46 or -PW47 Power Supply

• 2755-NC43 or -NC48 Configuration Cable

• 2755-NB40 or -NB41 Wiring Base (Ser. A/Rev. B or higher)

• 1747-L532, -L541, -L542, or -L543 SLC Processor

• 1746-A4, -A7, -10, or -A13 Chassis

Ground Screw on Wiring Base

The wiring base of the AdaptaScan Reader has an RS-485/RS-422 terminal block for point-to-point or network connections.

This section shows three connection options:

• Connecting readers to SLC 5/03

• Connecting readers to SLC 5/04 using two 1747-AIC Modules

• Connecting readers to SLC 5/04 using one 1747-AIC Module

Note: You can use the 1761-NET-AIC Advanced Interface Converter in place of the 1747-AIC Module.

Important: The DH485 network cable requires proper shielding,

grounding and termination. Refer to Data Highway/Data Highway Plus/Data Highway DH485 Cable Installation Manual (Publication 1770-6.2.2).

Publication 2755-6.8

Important: When setting up a DH-485 network using an

AdaptaScan, make sure that the nodes on the network are in sequential order. The SLC 5/03 or 5/04 should be Node 1, and AdaptaScan should be Node 2, and each node after that should be 3, 4, and so forth. If other DH-485 nodes are needed (i.e. DTAM, etc...), the AdaptaScan node number(s) must be first. Node gaps must be avoided in order to prevent the AdaptaScan from Soliciting of Successor (SOS). By preventing SOS, bar code throughput is maximized as it is sent to the SLC. In other words, when setting up the AdaptaScan via DH-485 the first priority is to process bar code data instead of finding node gaps.

Connecting Readers to SLC 5/03 Controller

You must use a link coupler if the distance between the reader and the SLC is greater than 15.2 meters (50 feet). The reader can connect directly to another RS-485/RS-422 device. Point-to-point and network connections are the same.

This section provides the SLC ladder logic program for CALL 22. The BASIC module is located in slot 1 of the SLC chassis. The SLC 500 processor is located in slot 0.

At rung 2.0, data is copied from the M1 file when the handshake bit (I:1.0/8) is set by the BASIC module. The SLC processor sets the handshake bit (O:1.0/8) once the data has been copied out of the M1 file. Setting the bit triggers the BASIC module to turn off bit I:1.0/8. The first word of the M1 file contains the byte count and this word is not included in the data byte count. The following ladder logic program example has a maximum of 6 bytes of data. I:1.0/8 is the handshake bit from the BASIC module to the SLC processor. O:1.0/8 is the handshake bit from the SLC processor to the BASIC module.
