From the K3S manual, p. 18: *Set the CONFIG:RS232 menu parameter to USB. Exit the menu.* • With the USB cable plugged in and the K3S turned on, determine which COM or sound device ports have been assigned to the K3S. This can be done from within applications. On Windows PCs, an alternative is to locate the Device Manager (Start > Control Panel > System > Hardware), and view its list of Ports. When you plug in the USB cable from the K3S, a new COM port will appear in the list.
If you don't have this item set, the K3 won't recognize the USB connection and will be expecting a serial port connection. In your MAC look for new connections after you set CONFIG:RS232 to USB. If it's already at USB and won't recognize, then you need to call Elecraft tech support. 73, Guy On Sat, Feb 25, 2017 at 1:42 PM, PHILIP GRAITCER <[email protected]> wrote: > I am unable to connect the USB on my K3, modified with a KIO3B set of > boards, to my MacMini, running OS10.9.5.
