The KXUSB cable plugs into the common USB port on a computer and creates a virtual COM port, when the appropriate drivers are also installed on the computer.  





Q:  I have an Apple computer and a Linux computer.  Do I need to order the KXSERa instead of the KXUSB?

A:  No.  At order time, a KXSERa cable can be substituted for the KXUSB.  The KXSER cable is designed to connect to a 9-pin COM port on a computer.  

If you have a USB port on your computers, we recommend the KXUSB cable that ships automatically with the KX3 or KX2 and other Elecraft products.

Q:  I have an older laptop that still has a 9-pin COM port on it but it also has USB ports available.  Which cable should I use?

A:  Where possible, we always recommend the KXUSB cable.  This cable provides the flexibility to connect to most any newer computer available today.

Q: I ordered the KXSERa cable when I ordered my KX3 and KX2.  I have now changed computers which only has USB ports.  What should I do?

A:  You can order the KXUSB cable separately as Elecraft product KXUSBa.
