Elecraft K3 MCU version 5.33 added the new "USB SAFE" option as a default (CONFIG:PTT-KEY, Tap '1'), which prevents unexpected transmissions when you restart Windows or reconnect an FTDI adapter.
This works fine when controlling a K3 or K3S via USB, but it doesn't help when using an FTDI USB-to-Serial adapter for CW / FSK / PTT keying on a separate serial port. I've published a 2-page document online, with screen shots, describing step-by-step how to use the Windows Device Manager to correct the default "Serial Enumerator" and "Modem Control" options set by the FTDI drivers, options which Windows unfortunately enables every time you connect a new FTDI adapter. Every FTDI port must be independently configured at least once. The short link to the online document is here: https://bit.ly/FTDItip These FTDI settings are also recommended when using the S-BOX-USB <https://bit.ly/S-BOX> with a K3 or K3S, especially when used with the RemoteHams "Use RTS as Power" option. If anyone on this list uses a MAC or Linux box with an FTDI adapter or FTDI KUSB cable, and the macOS offers the equivalent device options, please send me the screen shots (.PNG format preferred), and I'll add them to the document. Thank you! 73, Bob, N6TV https://bit.ly/S-BOX ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to [email protected]
