TIWAY I Overview

The Series 500 NIM provides several features which ensure maximum
network signal integrity.

•

Each communication port is provided with a “jabberstop” circuit to
disable the port’s transmitter in the event of a communication port
failure. Such failures can cause continuous network transmission
which would dominate the communication channel.

•

Built–in self tests guard against failure of the NIM itself. Chapter 3
provides a complete description of these built-in tests.

To date there have been four releases of Series 500 NIM software.
