Cable Installation (Interface Specific)

RS485

The following steps describe how to properly install the cables for an RS485 scanner application. The scanner must then be configured to match the host’s RS485 parameters. Cable installation alone does not guarantee that the scanner will communicate properly with the host system.

Note: Configuration bar codes are located in the MetroSelect Configuration Guide (PN 00-02407x) and the MS2xxx Stratos Series Configuration Addendum (PN 00-02034x).

1.Turn off the host system.

2.Plug the 10-pin RJ45 end of the RS485 interface cable (PN 57-57212x-N-3) into the 10-pin socket labeled ‘Scanner Host 46xx’ on the bottom of the scanner. Refer to the figure on page 27.

3.Connect the other end of the RS485 cable to communication port 9 on the host device.

Stop: Before continuing, verify that the RS485 cable is connected to the appropriate interface socket on the scanner. An incorrect cable connection can cause communication problems or potential damage to the scanner and/or terminal.

Note: Plugging the scanner into the serial port of the host device does not guarantee that scanned information will appear at the host device. A software driver and correct configuration settings are also required for proper communication to occur.

4.Plug the external power supply (PN 46-002xx) into the 3-pin Molex socket labeled ‘DC Power In’ on the bottom of the scanner.

Note: Check the AC input requirements of the power supply to make sure the voltage matches the AC outlet. The outlet should be located near the equipment and be easily accessible.

Using a switched AC outlet is recommended. The switch should be located on the operator’s side of the checkout counter in close proximity to the scanner to facilitate calibration and service of the unit.

5.Connect AC power to the transformer. If the AC outlet is equipped with an on/off switch, turn the power on.

6.Turn on the host system.

7.Configure the scanner to match the host system’s RS485 parameters.

Note: Refer to the MS2xxx Stratos Series Configuration Addendum (PN 00-02034x) under Scanner Configuration Bar Codes: IBM 3rd Generation Communication Defaults and IBM 3rd Generation Protocols.

Additional general configuration bar codes can be found in the MetroSelect Configuration Guide (PN 00-02407x).
