Parts for the customer end of the cable
can be of any industry-standard manufac-
turer. Use of a shielded-type connector is
recommended.
Cable should be constructed with data-
comm-quality cable that has an overall
mylar foil shield and braided-shield,
terminated to the appropriate pins and
connector shell at each end of the cable.
Twisted-pair 28GA cable is preferred,
with any of the pairs used for non-paired
signals.
The table on the right shows the pinouts
for the connectors.
