Installation Instructions
Chassis Interface Module for
1746 Local I/O
(Catalog Number 1747-PCIL)
Use this document to install the Chassis Interface module for 1746
Local I/O and connect it to a PCI Bus card for 1746 Local I/O.
The Chassis Interface module works with the PCI Bus card
(Cat. No. 1747-PCIS/PCIS2) and a connecting cable to make up
the 1747 PCI Bus Interface.

Compliance to European Union Directives
If this product bears the CE marking, it is approved for installation within
the European Union and EEA regions. It has been designed and tested to
meet the following directives.
EMC Directive
This product is tested to meet Council Directive 89/336/EEC
Electromagnetic Compatibility (EMC) and the following standards, in
whole or in part, documented in a technical construction file:
• EN 50081-2 EMC - Generic Emission Standard, Part 2 - Industrial
Environment
• EN 50082-2 EMC - Generic Immunity Standard, Part 2 - Industrial
Environment
This product is intended for use in an industrial environment.
Low Voltage Directive
This product is tested to meet Council Directive 73/23/EEC Low Voltage,
by applying the safety requirements of EN 61131-2 Programmable
Controllers, Part 2 - Equipment Requirements and Tests.
For specific information required by EN 61131-2, see the appropriate
sections in this publication, as well as the following Allen-Bradley
publications:
• Industrial Automation Wiring and Grounding Guidelines For Noise
Immunity, publication 1770-4.1

4 Chassis Interface Module for 1746 Local I/O
Setting the Jumper
The adapter has three separate jumpers on board.
Last State Jumper
Watchdog JumperUser Jumper
Watchdog Connector
(Internally connected to
the watchdog jumper
Last State Jumper
This jumper defines the state of I/O in case of a communication failure.
You must set the jumper to one of the following two settings:
• Last State –When communication with the scanner is lost (for
example, the cable is unplugged or the computer is turned off),
the 1746 I/O will hold their last state.
• Reset – When communication with the scanner is lost,
the 1746 I/O will be reset.
Watchdog Jumper
This jumper is internally connected to the watchdog connector. A detailed
explanation of this jumper’s usage is on the next page.

Chassis Interface Module for 1746 Local I/O 5
User Jumper
Your software application program has the ability to read the state of this
jumper. If you are using the API software, refer to publication 1747-6.5.3.
If you are using another software application refer to the documentation
for that software.
Using the Watchdog Jumper with the External Watchdog Connector
This jumper works in junction with the watchdog connector on the front
of the chassis interface module. The watchdog connector output is a solid
state switch that can switch a voltage range of 4.5V dc to 26.4V dc. The
connector plugs onto the front of the chassis interface module.
You need an external power supply to use the external watchdog. Adjust
the external load switched by the watchdog output to 20mA or less. The
watchdog output is normally off and turns on as a result of a watchdog
timeout condition due to an internal hardware failure. When this condition
occurs, a red indicator will light up on the status LED.
You must adhere to the watchdog output polarization to guarantee proper
operation.
