Communications signal from LRIS2K to VCD
The LRIS2K has several modes defined for some parameters, owing to which it can operate
in different noise environments and meet different application requirements.
Load modulation
The LRIS2K is capable of communication to the VCD via an inductive coupling area
whereby the carrier is loaded to generate a subcarrier with frequency f
generated by switching a load in the LRIS2K.
The load-modulated amplitude received on the VCD antenna must be of at least 10mV
when measured as described in the test methods defined in International Standard
ISO10373-7.
Subcarrier
The LRIS2K supports the one-subcarrier and two-subcarrier response formats. These
formats are selected by the VCD using the first bit in the protocol header. When one
subcarrier is used, the frequency f
When two subcarriers are used, the frequency f
is 484.28 kHz (f
continuous phase relationship between f
Data rates
The LRIS2K can respond using the low or the high data rate format. The selection of the
data rate is made by the VCD using the second bit in the protocol header. It also supports
the x2 mode available on all the Fast commands.
