This read-write object inverts the transmit data polarity: normal(0) or inverted(1). Like cdd564RxDataInversion but on the transmit side, this flips the logical sense of the outgoing bit stream to match a polarity convention expected by specific far-end equipment, a setting sometimes needed purely for interoperability with a particular vendor's demodulator rather than reflecting any actual fault. If a far-end demodulator from a different vendor reports consistently garbled data despite a clean RF lock, toggling this object is one of the standard interoperability fixes to try before suspecting a deeper protocol incompatibility.
