User Manual

For any (external) antenna connection the maximum cable length
allowed can produce a decibel loss no greater than 6dB. Each coax
cable type and gauge will have different loss characteristics and the
installer should contact the cable supplier to determine the suitability
any cable for their application.
In most locations, it is probable that null spots will exist in the
coverage of any single antenna. If a tag is in a null spot even though it
is within range of an antenna it will not be interrogated. This is
typically not a problem when tags are moving through a read zone,
but if the tags must be interrogated while stationary it will be
necessary to create redundancy in the read zone.
7 i-Q Tags
IDENTEC i-Q tags are available in a number of configurations to
match the tag with the application. Tags of different types can be
mixed in a single system and can be interrogated simultaneously by
an i-CARD. Tags are available as read only, read/write with 8 KB of
memory, and a read/write tag with and optional temperature
monitor. Tag memory is expandable to 32KB.
