QYT KT-8900 Go to product viewer dialog for this item. programming cable utilizes a standard or TRRS (Tip-Ring-Ring-Sleeve) audio jack interface, though only three connections are required for data transfer. The pinout typically follows the standard found in many similar Chinese mobile radios. Programming Cable Pinout (3.5mm Jack)

If you are trying to build your own cable or repair a broken one, the layout on the PCB inside the connector shell is crucial. The standard "Kenwood 2-pin" style (which many mistakenly try to use) separates the Speaker and Mic into two distinct plugs.

Here is the typical logic flow for the connector found on the QYT KT-8900 accessory port:

Never connect standard RS-232 serial cable lines (which operate at ±12V) directly to these pins. The QYT KT-8900 The standard "Kenwood 2-pin" style (which many mistakenly

To interface this radio with a computer, you cannot use a straight-through audio cable. You must use a USB-to-TTL serial adapter module (such as an FTDI, CP2102, or CH340 chip) that operates at . The serial adapter translates the computer's USB signals into the asynchronous serial data that the radio's microprocessor understands. Exact Pinout Configuration

Solder or connect the opposite end of the cable to your USB-TTL module terminals (TXD, RXD, and GND). Double-check that your lines cross correctly: , and Radio TX to USB RX . 5. Software Driver and Testing Configurations
