Qyt - Kt8900 Programming Cable Pinout Top

This report provides the pinout mapping for the QYT KT-8900 programming cable when viewed from the top (connector face toward you). It covers the common 6-pin cable used to connect the radio's programming/data port to a USB-to-serial adapter or programming box.

Connect the wire intended for the USB adapter's pin to the Ring 1 tab. qyt kt8900 programming cable pinout top

A straight or crossover Ethernet cable will not work. The voltages are wrong, and Ethernet uses differential pairs (TX+/TX-), not single-ended TTL. This report provides the pinout mapping for the

On the USB adapter, TXD must connect to the radio’s RXD (Pin 6). Similarly, the adapter’s RXD connects to the radio’s TXD (Pin 3). This is a classic null-modem style connection. and Ethernet uses differential pairs (TX+/TX-)
