INSTRUMENTATION PORT AND DEVICES
The Instrumentation Port (I/P) is used to connect the tester to one or more devices which are used to expand
the diagnostic capability of the tester. The I/P connector receives signals which provide a serial
communication link from “smart” instrumentation devices. These devices contain microprocessors which
can perform specific diagnostic functions and send information to the tester.
The Instrumentation Port also contains circuits which can be used for making direct signal measurements.
This capability is used to support instrumentation devices which may not require a microprocessor. The
Diagnostic Test Lead set is an example of this type of instrumentation device.
