Transceiver Variants
The transceiver is available in two variants – TR2I and TR2M
The standard TR2M, in Transmit Mode, 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 Analogue and Digital Data output on the receiver. This
variant can be used for applications where data inversion will be problematic.
The TR2I is designed to be pin and polarity compatible with existing industry standard modules.
Analogue and Digital Data Output are inverted relative to original transmitted signal in Receive Mode.
TR2I, in Transmit Mode, 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 Analogue and Digital Data output on the TR2I in Receive
Mode. TR2I can be used as an exact plug-in replacement for existing industry standard modules.
