RFID on leeky

hi

i am trying on leeky(em4095 RFID reader v2.0) project.
the problem i face is i cant read the tag...when i connect it to the hyperterminal.it only show em4095 RFID reader v2.0. when i attach the tag..no signal is captured..the tag i use is em4100..

i try to measure the signal waveform on 2 point of the antenna..one end i get is sinewave and the others end is square wave...Y?? i thought both should be square wave? the squarewave i get is approximate 125khz..

so anyone can help me out?

thanks....
