CHAPTER 2 INSTALLATION AND
SPECIFICATIONS
Introduction
This chapter provides information for connecting and mounting the PL3307 decoder.
General Information
Grounding
The mounting holes for the PL3307 include exposed copper that may, if necessary, be used to electrically
ground the decoder to the host using metal screws. If installing the PL3307 in a host where there is a potential
to inject ground noise, use nylon or other non-conductive hardware. In this case the PL3307 ground is provided
through the host connector.
Electrical Isolation
Both sides of the PL3307 decoder board include components and electrical conductors that must be isolated
from contact with components on the host device. See
PL3307 Decoder Board on page 2-3 .
Electrostatic Discharge (ESD)
The PL3307 decoder is protected from ESD events that can occur in an uncontrolled environment, however,
use care when handling the module and apply standard ESD precautions such as using grounding wrist straps
and handling only in a properly grounded work area.
Environment
Enclose the PL3307 decoder sufficiently to prevent dust from gathering on the printed circuit board and
components. Dust and other contaminants can eventually degrade performance. Motorola does not guarantee
performance of the decoder when used in an exposed application.
