• Manufacturer: Radiometrix Ltd

Transmitter variant
RX2M is designed to be pin and polarity compatible with existing industry standard modules. AF and
Data Output are inverted relative to original transmitted signal.
The transmitter is available in two variants – TX2I and TX2M
The non-inverting transmitter called TX2M frequency modulates the carrier frequency in the normal
sense whereby higher modulating voltage increases the carrier frequency and lower modulating voltage
decreases the carrier frequency which results in an inverted AF and Data output on the receiver. This
will be the standard module and exact plug-in replacement for existing industry standard modules.
The inverting transmitter called TX2I reverses the Frequency Modulating order whereby the higher
modulating voltage decreases the carrier frequency and lower modulating voltage increases carrier
frequency which results in non-inverting AF and Data output on the receiver. This variant can be used
for applications where data inversion will be problematic.
