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.
Publication 1747-5.32–April 1998
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.

General Operation
The adapter has no microprocessor on board that scans or controls the
1746 backplane. The scanner board contains the I/O scanner
microprocessor and connects to the I/O backplane via the parallel cable
(1747-PCIC) and adapter module.
The control program running on the PC monitors and controls the 1746
I/O via the scanner’s dual port memory. All LED indicators on the adapter
are controlled by the scanner.

Understand CSA Hazardous Location Approval
CSA certifies products for general use as well as for use in hazardous locations. Actual CSA
certification is indicated by the product label as shown below, and not by statements in any
user documentation.
Example of the CSA certification product label:
To comply with CSA certification for use in hazardous locations, the following information
becomes a part of the product literature for this CSA-certified industrial control product.
• This equipment is suitable for use in Class I, Division 2, Groups A, B, C, D, or non-hazardous locations
only.
• The products having the appropriate CSA markings (that is, Class I, Division 2, Groups A, B, C, D) are
certified for use in other equipment where the suitability of combination (that is, application or use) is
determined by the CSA or the local inspection office having jurisdiction.
Important: Due to the mo dular nature of a programmable control system, th e product with the highest
