1.3 XCRF-500 reader series
XCRF-500 reader series are designed for reading and writing
UHF tag of XCTF-5000, while keeping compatible with
AMTECH vehicle tag.
XCRF-500 reader series provides 1 to 4 radio frequency
interfaces for external radio frequency antennas. Radio
frequency cable should employ low loss cable, and the length
of radio frequency cable equipped with reader is 10 meters.
Lengthening the radio frequency cable or using general radio
frequency cable will affect the reading/writing range of reader.
Note:
(1) Joint between radio frequency cable and reader is N-type
joint, connection of which should be tight and reliable.
Over-tight joint connection would damage the joint socket,
while a loose one would cause system performance decline
(reading/writing distance).
(2)Switching on the power and transmitting microwave prior to
disconnecting antenna might cause serious damage to the
system.
(3) Unused antenna port should be connected to 50Ω /20W
load.
