This cable is fitted with 2.5 mm stereo jack and based on the FTDI FT232RL USB to serial UART interface. It is designed specifically for quick and easy programming via USB port of Yaesu VX-8G, VX-8GE, and VX-8GR handheld transceivers. The power supply is done over the USB interface, following the USB 2.0 specifications. This is not a straight forward cable, there is an internal converter circuit board (interface) mounted in the USB shell. This single programming cable-interface completely replaces Yaesu CT-143 Serial Data PC Cable.
The cable communicates directly with a computer through the now popular and standard USB interface. A physical Serial Port connection is not needed since the FTDI drivers emulate a virtual Serial Port which communicates with a radio at the required TTL voltage levels. The programming cable is compatible with all Windows, Linux, and Mac operating systems that support USB operation. Please note that the Programming Software is not supplied with the cable.
Virtual COM Port Drivers are available at the FTDI website. Virtual COM port (VCP) drivers cause the USB device to appear as an additional COM port available to the PC. Application software can access the USB device in the same way as it would access a standard COM port. Installation guides are available from the Installation Guides page of the Documents section of the FTDI website for selected operating systems.
