8. TROUBLESHOOTING
8.1. Introduction
This section provides information on maintaining, troubleshooting and repairing the
IEEE-488 interface card.
8.2. Periodia Maintenance
The IEEE-488 interface card has no internal adjustment and does not require periodic
calibration. Bowever, the following actions are recommended for preventive mainte-
nance on a once-a-year basis (or more often, in high humidity environments).
The IEEE-488 bus connector (CN1) and the golden fingers for the PC I/O slot should
be cleaned to prevent wax and dirt build-up. Spray the contacts lightly with a good
contact cleaner, such as trichflorethlyene and use a cotton swab to rub off the dirt and
excess cleaner.
8.3. Troubleshooting Procedure
The majority of problems are due to poor cabling, contacts or incorrect device
programming.
The remedy for these two problems is to keep the connector and golden fingers clean
and tight and also to read each device’s manual to gain an understanding of its unique
initialization and setup requirements. For other problems, the troubleshooting guide
lists the symptom, probable cause and suggested corrective action.
