Vertex VX-820 / 920 Series CT-109 USB Programming Cable
This cable is based on the Prolific PL-2303TA USB to Serial Bridge Controller, and designed specifically for quick and easy programming via USB port of the following Vertex Standard VX-820/920 series handheld transceivers: VX-821, VX-824, VX-829, VX-921, VX-924, VX-929, VX-P821, VX-P824, VX-P829, VX-P921, VX-P924, and VX-P929. 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 interface cable completely replaces Vertex CT-109 COM-port interface kit. 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 supplied 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 operating systems that support USB operation. Please click here to download necessary USB drivers. This zipped file is completed with full driver installation instructions. Please note that the Programming Software is not supplied with the cable.
