The uses a 3.5mm TRRS (4-pole) or TRS (3-pole) jack for programming, located on the rear panel. Unlike many other mobile radios that use an RJ45 mic port for data, the KT-8900 utilizes a standard audio-style connector for its serial interface. Programming Cable Pinout (3.5mm Jack)

Use heat-shrink tubing to protect the joints and make the cable sturdier. Software Tips CHIRP Support: Most QYT KT8900

Before diving into the pin numbers, let’s clarify the "top" reference. The QYT KT8900 uses an connector for programming, identical to an Ethernet plug. However, unlike network cables, the pinout is not T568A or T568B.
