5 Installation
This chapter describes the installation and antenna connection
procedure for an i-CARD in mobile equipment, such as a handheld
scanner. For installation in an i-PORT, see the i-PORT Reference
Manual.
Important Note to Installer:
This device requires professional installation by a certified
electronics technician or electrical engineer, following each and all
procedures of the installation manual. This device is only legal to
operate in conjunction with the antenna type approved by FCC and
Industry Canada.
The installer is taking legal responsibility that all steps outlined in
the IDENTEC installation manual have been executed properly, and
that the installed device is complying with FCC Part 15 and the limits
for a ‘Class A Digital Device’, as defined by Industry Canada.
5.1 Physical Installation
The I-CARD plugs into either an i-PORT’s appropriate slot, or into
any PCMCIA slot with a 5V supply voltage.
5.2 Electrical Installation
Every time the i-CARD’s 5V power is cycled it is being reset.
Thereby, a default sequence table is automatically loaded, limiting
RF output power to a low level. The receiver sensitivity is also limited
in this process.
6 i-CARD Antennas
Antennas for use with the i-CARD are required to have a gain equal
to or less than 3dB
(ic)
. It is recommended that the antenna
polarization should be elliptical or circular, although in applications
where the orientation of the tag is in a consistent and known position
linearly polarized antennas can also be used.
Normally, a miniature antenna, like a quarter-wavelength whip, a
bent half-wavelength dipole or a subminiature patch antenna should
be used. These antennas would typically be integrated in the portable
device.
