AN-X4-AB-DHRIO Data Highway Plus Module
The AN-X4-AB-DHRIO module running Data Highway Plus (DH+) firmware connects a computer
or other device on Ethernet to an Allen-Bradley Data Highway Plus network.
The AN-X4-AB-DHRIO (DH+) module:
• can act as any valid Data Highway Plus station number, from 0 to 77 octal
• supports all Data Highway Plus baud rates, 57.6, 115.2 and 230.4 Kbaud
• maintains Data Highway Plus diagnostic counters
• can route messages from Ethernet to Data Highway Plus, using IP aliasing
• can route messages from Data Highway Plus to destinations on Ethernet, using the router function
You can use the AN-X4-AB-DHRIO (DH+) module with Rockwell programming software to
communicate with PLCs such as the PLC-5 over Data Highway Plus from a computer on Ethernet.
Refer to page 18 for details.
You can use a DDE or OPC server, for example RSLinx, on Ethernet to access Data Highway Plus
using the AN-X4-AB-DHRIO (DH+). Refer to page 23 for details.
The AN-X4-AB-DHRIO (DH+) module has a web interface for configuration of the Data Highway
Plus station number and baud rate and for monitoring diagnostic counters and the active station list.
You can communicate with the module using any standard web browser.
The AN-X4-AB-DHRIO (DH+) module monitors the Data Highway Plus network traffic and
displays usage statistics such as:
 overall network loading

AN-X4-AB-DHRIO (DH+) Page 7
 the percentage of network time used for the commands from each station plus the percentage
of network time used by responses to those commands, to identify the stations creating the
most network traffic
 the amount of network time used by each station in sending responses to other stations, to
identify heavily loaded stations
Refer to page 44 for details.
You use the web interface to send various configuration files to the AN-X and to retrieve them, and to
update the AN-X firmware.
A jabber inhibit timer is implemented in the module’s hardware. If the network transmitter is on
longer than 150% of the longest network frame time, the transmitter is forced off and the module is
placed into a safe fatal failure state.
Hardware Features
The module has:
• LEDs to indicate the status of the connection to the Ethernet, its own internal state, and the
state of the connection to the Data Highway Plus network
• an Ethernet connector
• a 3-pin Phoenix connector to connect to the Data Highway Plus network
• a power connector
• a microSD card for storage of configuration data and firmware
The pinouts on the power and the Data Highway Plus connectors match those on the AN-
X2.
Cables for the AN-X2 can be connected to the AN-X4 without change, though they may need to
be rotated 180 degrees.

Package Contents
• AN-X4-AB-DHRIO module
• Phoenix Power and Data Highway Plus connectors
Using the MicroSD Card
The AN-X4 microSD card stores configuration data and firmware.
There are no restrictions on the size or speed of the card. The format must be FAT-16 or FAT-32.
The microSD card must be present while the AN-X4 is running.
WARNING! Do not remove the microSD card while the AN-X4 is powered on!
There are several configuration files on the SD card.
Function File
Ethernet configuration IPCfg\IPConfig.txt
Data Highway Plus Configuration Dhp\AnxDhpCfg.txt
Alias Configuration Dhp\AnxDhpCfgHmiAlias.txt
Router Configuration Dhp\AnxDhpCfgRouter.txt
Firmware to run Firmware\FirmwareCfg.txt
All files should be created and editied with a plain text editor such as Windows Notepad.
If the AN-X4 is inaccessible from Ethernet because of its settings, or is in an unknown state, you can
power down the AN-X4, remove the microSD card and edit the file IPConfig.txt. Refer to page 14
for details.
When you have finished editing the file, reinsert the card in the slot at the back of the AN-X4 and
restart the AN-X4.
WARNING!
If you remove the card to edit the configuration file, push the card in
straight or the card might fall inside the case and you will have to
disassemble the AN-X4 to retrieve it .

Comparison with the AN-X2
If you are familiar with the AN-X2, or are replacing an AN-X2 with an AN-X4, you should be
aware of the following:
 The power and Data Highway Plus cables are the same, but may need to be rotated 180
degrees.
 The configuration files are similar but are saved in different locations on the microSD
card
 The web interface is improved
 The errors displayed on the LEDs have changed
 You can run different versions of the same firmware, e.g., Data Highway Plus firmware,
for example for debugging
 As shipped, searches for a DHCP IP address at startup for 10 seconds, then reverts to
static IP address 192.168.0.246
 Case is smaller

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.
