Re: [Elecraft] KIO2 and KUSB for K2?
Paul, You must construct the special cable that is specified in the KIO2 manual - you can make it a short one if you want. That cable has a DE9 connector on the PC end which you can plug into a serial port or into a USB to serial adapter - The KUSB sold by Elecraft is a good choice -- if you choose another USB to serial adapter, make certain it uses the FTDI chipset. 73, Don W3FPR On 8/23/2021 1:22 PM, Paul Huff wrote: I am thinking about adding the KIO2 RS-232 serial interface to my K2 but I don’t know very much about computer hardware.

Or is there something else that would be needed? *** Not sure about the KIO2, but I did peruse the data on the serial port included on the KPA100, which is probably the same. In the case of the KPA100, you MUST use a custom cable - either supplied by Elecraft, or made up with their schematic. This is because Elecraft used "spare" pins on the serial connector for things that have nothing to do with serial communications. For serial comm, you connect ONLY pins 2,3 and 5 on the 9-pin serial connector. pin 2 is TxD ( data from the K2 to the computer ), pin 3 is RxD ( data from the computer to the K2 ), and pin 5 is the common/ground. Again, this is specific to the KPA100; I don't know if it applies also to the KIO2, but I suspect that it does. - Jerry KF6VB __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to arch...@mail-archive.com
[Elecraft] KIO2 and KUSB for K2?
I am thinking about adding the KIO2 RS-232 serial interface to my K2 but I don’t know very much about computer hardware. Would the KUSB serial cable that is also sold by Elecraft then be needed to connect the KIO2 to the USB port on my Mac computer? Or is there something else that would be needed?
