Installation
Prevent Electrostatic Discharge
The module is sensitive to electrostatic discharge.
WARNING!
Electrostatic discharge can damage integrated circuits and
semiconductors. Follow these guidelines when you handle the module:
• Touch a grounded object to discharge static potential
• Do not touch the connector pins
Power
AN-X requires DC power input of anywhere from 12 to 24 VDC
The pins on the power connector are chassis ground, negative voltage and positive voltage. Pin 1 is
closest to the Ethernet connector.
Power consumption is 240 mA @ 12VDC or 120 mA @ 24VDC.
The part number for the power connector is Phoenix MSTB 2.5/3-ST-5.08 (1757022)
Data Highway Plus Cabling and Termination
Follow Allen-Bradley cabling recommendations for Data Highway Plus. Refer to Approved Vendor
List for DH, DH+, DH-485, and Remote I/O Cables, publication ICCG-2.2, February 1996.
The network cable must be terminated with terminating resistors attached to the physical ends of the
network, usually 82 ohm, but refer to Allen-Bradley documentation since some devices require 150
ohm terminators. There should be two and only two terminators on the Data Highway Plus network.
On the AN-X module, the Data Highway Plus connections should be line 1, shield, line 2.
