[Elecraft] RS232 interface

[G4GNX]

I just got round to trying to interface my K3 to a PC.

I starred off with 2 different Prolific USB/RS232 cables, but although they both showed up as correctly installed drivers.
I tried running the K3 Utility but although it did seem to communicate once when I tried “Check communication”, but refuses to exchange data and gives “Not read EEPROM” errors.
That said, the same cables will not communicate with my Power Chute UPS, so I’m assuming that there is a levels problem with the Prolific cables? Can anyone confirm this.

I have now ordered a genuine FTDI cable, as that’s the recommendation by Elecraft.

I presume that there’s nothing to setup in the K3 and K3/Utility communication is automatic.
