Programming Cable The programming UART chip is in the radio, not the cable, and the proper drivers load automatically making the cable virtually Plug and Play.   What makes this radio unique is the programming cable is a standard USB to Micro-USB cable.  As shown in the picture below, there are two input areas. One is for the programming cable, the other for accessories. The accessory jack is an HYT style.  This is not compatible with the Kenwood K1 jack found on many handhelds.
