[Elecraft] K3s USB failure?

[Jack Brindle]

Make sure that BOTH DE9 connectors are firmly plugged onto the P3. I ran not this situation myself over the weekend. The serial data needs to flow through the P3 and back to the K3S where it is then used. If one of the DE9s is not properly connected you won’t have a full path and the USB will not work properly.

In my case I forgot to connect the top DE9 onto the P3 and things didn’t;t work. As soon as the connector was plugged in, the software (N1MM+) became very happy.

73!
