Existing Interference
Interference from RF and electrical sources can degrade system performance and must
also be considered in the site design. Fluorescent lights, neon signs, nearby radio sta-
tions, or power lines can interfere with the optimal operation of the system. The mag-
netic impulse noise from relays that control gate opening and closing can also disrupt
the RF signal.

netic impulse noise from relays that control gate opening and closing can also disrupt
the RF signal.
Interference may degrade both reader and tag performance. Existing interference at
the site may be shielded, removed, or positioned further from the Encompass 4/4800
Multiprotocol Reader and/or antenna. In some cases, changing the operating fre-
quency of the Encompass 4/4800 Multiprotocol Reader may provide a simple solu-
tion. Readers in proximity should have at least a 2 MHz frequency separation. See

Electrical and Communications Requirements
All construction work at the site must be completed before installing the Encompass
4/4800 Multiprotocol Reader . Electrical and communications cables should be
installed according to all applicable local and federal building code requirements. Spe-
cific instructions for positioning and installing the Encompass 4/4800 Multiprotocol
Reader are discussed in Chapter

Junction Box
Use a watertight junction box that meets applicable local and national building codes
for connecting power and communications wiring. The junction box houses the termi-
nal strip for power and communications connections. TransCore recommends a
NEMA Type-4 junction box with a back mounting panel.

Power and Communications Cables
Cable length for power and communications depends on the physical characteristics
of the Encompass 4/4800 Multiprotocol Reader installation site. Table 2-1 lists acces-
sory kits available for cabling options based on your site’s requirements.
