TransCore 0596465PT15 Manuel D’Utilisation

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.
Interference may degrade both reader and tag performance. Existing interference at 
the site may be shielded, removed, or positioned further from the Encompass 4H 
Reader. Strong RF sources of any frequency, in proximity to the tag, can preclude the tag 
receiving the reader interrogation (

All construction work at the site must be completed before installing the Encompass 
4H Reader. Electrical and communications cables should be installed according to all 
applicable local and federal building code requirements. Specific instructions for posi-
tioning and installing the Encompass 4H Reader are discussed in 

Chapter 4, ”Install-

ing the Encom pass 4H Reader”. 

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. 

Cable length for power and communications depends on the physical characteristics 
of the Encompass 4H Reader installation site.
