Troubleshooting and Repair
5.1
INTRODUCTION
This section describes the maintenance testing, troubleshooting, and repair
procedures for ICS's Model N4865A GPIB
LAN Adapter.
5.2
MAINTENANCE
The N4865A does not require periodic calibration and has no internal adjust-
ments. However, if the N4865A is used in an application where the IEEE 488
bus cables are frequently changed, the N4865A's IEEE 488 Bus Connector
may occasionally require cleaning to remove wax and dirt buildup. New bus
connectors are shipped with a brightener (thin wax like fi lm) on them. Depend-
ing upon usage, enough of the brightener may buildup on the N4865A's bus
connector to cause intermittent operation.
The brightener is an organic compound and may be cleaned off by washing the
connector with a mild detergent solution followed by an alcohol wash.
5.3
TROUBLESHOOTING
Table 5-1 lists several common fault indications and suggests actions that
can be done to either clear the fault or isolate the problem to a faulty piece of
equipment. Table 5-2 lists the N4865A's self test error codes and most prob-
able faulty component.
