    You could try to measure if -RXD and GND are connected (Ohmmeter). If so GND (-RXD) can be connected and will be the reference for the output signal. If not I suggest you contact the manufacturer and ask them how to hook it up. The TE pin is obviously not used for normal operation.

    Btw, it's for OOK modulation.

    It means ON-OFF-KEYING. The carrier is just turned on and off bitwise. That's the modulation.
