[Elecraft] Can not connect KIO3B USB with my MacMini

[Guy Olinger K2AV]

>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.
