1.9. Shielding

In case of increased interference, shielded bus cables are recommended

for both intra and inter-module wiring . In addition, shielding should

also be employed for power supply and signal cables.

Shielding Recommendations:

1. The shield should be connected with protective grounding at each bus

connection.

2. The shield should be applied several times along the course of

the cable.

3. The shield should be applied directly to the computer, or to separate shield

rails.
