readily available from commercial distributors. GE Fanuc recommends
that you purchase rather than make transceiver cables.
Transceiver Description
Depending on your particular application, any of several types of user-supplied
transceivers may be used. The two most commonly used in industrial environments are:
10Base5 and 10Base2. A typical configuration for each unit is shown in Figures B-3 and
B-4.
