Hi John, If you have *CONFIG: RS-232* set to *USB*, then both K3 serial ports are fixed at 38400 baud, so you have to use that setting in the SteppIR controller, and set the radio type to Elecraft (or Kenwood).
A custom cable is required to allow the SteppIR auto-track to work via the K3 9-pin serial port at the same time. This is something I implement in my Serial Box (S-BOX <https://bit.ly/S-BOX>) offering so that one can use standard economical serial cables and omit all Y-adapters and expensive custom SteppIR cables. The serial cable connection from the SteppIR to the K3S serial port (via the Elecraft RJ-45 to DE-9F adapter cable, P/N E980297) must make no connection on Pin 3 (TXD), and Pins 7 and 9 must be shorted. Finally, a logging program must be actively polling the K3, or CONFIG:AUTO INF must be set to AUTO 1, or else the SteppIR won't get any frequency data. If you are also connecting a P3 via the CBLP3Y, then a serial Y-cable or S-BOX must be connected to the P3 "PC - RS232" port, with one side going to the CBLP3Y male DE-9 connector, and the other side going to the SteppIR cable. 73, Bob, N6TV https://bit.ly/S-BOX https://bit.ly/Y-BOX On Fri, Jul 31, 2020 at 12:36 PM John Simmons <jasimm...@pinewooddata.com> wrote: > K3 won't do both RS232 and USB at the same time.
