... Analogue gain may be set for an input level of 50mV – 2V without appropriate test equipment. Contact factory for details 2. Carrier detect on RX2M mutes the AF and DATA outputs when RF input signal is <-123dBm. This can be factory disabled if required. 3. There are no pullups on the open collector outputs. External pull-up resistor should be used. ...

... For TX2M, TXD (Pin Serial Port can be switched from PGM (Pin C6) to MOD TXD (Pin C8) with no RS232 driver in between. However, in RX2M, MOD RXD (Pin C9) requires an RS232 line driver before it can be connected to RXD (pin serial port. Some of the RS232 line drivers can be powered from the regulated +4 ...

... 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 ...
