SmartPass® Integrated Reader 2450 MHz (High Voltage) System Guide
to reach and return from a tag within the designated range. Also, if the antenna
becomes misaligned or some nearby permanent structure is added or removed,
system operation can be seriously affected. SmartPass should be placed in an area
where it is not likely to be bumped out of alignment.
Other SmartPass Units in the Area
If multiple SmartPass readers are installed near each other, they must be configured
with a frequency separation of at least 3 MHz.
Note: Never install two SmartPass reader systems directly facing each other, or
SmartPass receiver circuitry and decoder will not operate reliably
Junction Box
A junction box is needed at the site. TransCore recommends a NEMA Type 4 or IEC
IP54 junction box with a back plate. The junction box will house the terminal strip
for communications and power.
The junction box must be a watertight box that meets applicable local and national
building codes. It must have watertight conduit for any cables that will attach to
SmartPass. SmartPass will be used with a 90–260 V AC power supply. The box must
have conduit on both the supply and reader sides. SmartPass is fitted with a 1.3-cm
pipe NPT-threaded connector that allows watertight conduit to be installed.
Caution
Power and communications lines must use separate conduits.
Vorsicht
Strom- und Kommunikationsleitungen müssen durch getrennte Kabelkanäle
geführt werden.
Precaución
Se deben emplear conductos separados para las líneas de alimentación y de
comunicaciones.
Précaution
Les lignes d'alimentation et de communications doivent emprunter des conduits
différents.
Attenzione
Le linee dell’alimentatore e di comunicazione devono usare condutture separate.
