both antenna 1 and antenna 2 of which can be connected with external antenna. XCRF-504W is four-ported reader, antenna 1, antenna 2, antenna 3 and antenna 4 of which can be connected with external antenna. In the case that the reader you ordered is multi-ported, it is necessary to connect the unused antenna ports to 50Ω /20W dummy load in order to protect the reader.
1.1 System Advantage From the point of data collection, radio frequency identification system completely resembles bar code system. In the course of data collection, bar code system adopts one-way communication, i.e., bar code sensor (reader) reads information from bar code in non-touch way. During such information flowing, bar code is totally in a passive and subordinate position and the communication is one-way, i.e., information is transmitted to bar code sensor from bar code tag.

Chapter 3: RF Communication Generally, the system performance of the devices employing radio communication technology is very sensitive to signal interference and attenuation. This chapter addresses the optimisation issue of radio frequency communication between XCRF-500 reader series and electronic tag, which includes: （1） Signal interference （2） Signal attenuation （3） Optimisation of system performance 3.
other devices; ø Radiation source of other radio frequency (RF); The influence of these interference sources can be eliminated or reduced by adjusting the installation position and direction of the reader and antenna. When radio frequency (RF) interference or noise exists, the performance of reader system (exchange data with electronic tag) will dramatically decline. The reader can only “receive” one signal at any time, not able to differentiate the unexpected “noise” and expected “useful RF signal”.
3.2 Signal attenuation/reflection Signal attenuation refers to the natural attenuation of signal strength with the distance increasing. Meeting blocks during signal transmission might also cause attenuation.
within reading area. When the electronic tag is positioned in dead corners, the communication between reader and tag will be very poor.
3.3 Optimisation of system performance Generally, it is impossible to precisely predict the system performance of the reader under any given circumstance (the root is the complexity of electromagnetic radiation, including the frequency stability of signal source, the direction of antenna, antenna side- lobes and the environment). However, the suggestions below are instructive to optimising the system performance in practice. ø Elaborately design and install the antenna of reader.
ø reading range could be affected by the nearby metal articles like the household appliance, equipments, metal frames, etc. ø Make sure that the objects attached with the electronic tags to be identified stay within the valid reading area for longer than 10 milli-second (regarding XCTF-5000 electronic tag). ø The polarization direction of the reader antenna shall be the same as that of the electronic tag antenna.
constant is usually larger than that of the air, and thus its effective wave length is shorter than that in the air), if its effective electrical length is adjusted to the optimal length in the air (the corresponding reading distance to the reader-writer is the longest), and when the antenna is packed in the non-conduct material, the electrical length of the antenna should be shortened to parallel the optimal effect in the air.
