Communication Connections and Setup
Chapter Objectives
This chapter describes how to connect the MicroView terminal to
communicate with peripheral devices. It contains the following
sections:
Wiring Guidelines
Here are some recommendations on how to reduce noise on the
communications connections:
•
Careful wire routing helps reduce or minimize electrical noise.
Route incoming power to the terminal by a separate path from
the communications cables.
•
Do not run communications wiring and power wiring in the
same conduit.
•
Where communications and power wiring must cross, make
their intersection perpendicular.
•
Proper grounding helps to limit the effects of noise due to
Electromagnetic Interference (EMI). To avoid problems caused
by EMI, all cables must be shielded and grounded at one end.
Grounding is also an important safety measure in electrical
installations.
