Trolley Scan(Pty) Ltd
Datasheet - OEM Receiver Module
The receiver module contains the frequency synthesizer, modulator and pre-amplifier for the energising section of the reader; and the magnetic mixers, I & Q preamps, DSP processor and RS232 drivers for the receiver. The module is programmed to implement the Trolleyponder(RIST) protocol for multiple transponders.
The receiver input stage uses a magnetic mixer so as not to overload in the presence of the energising field while being able to detect the very weak transponder data signal at the same operating frequency.
The Enhanced sensitivity handles extremely low power versions of EcochipTag transponders - that is transponders that operate on less than 200uW.
