KIO2 RS-232 to USB?

My computer does not have a 9 pin serial port. I have a 9 pin to USB
prolific cable/adapter that I use to connect my Ten-Tec RX320, that also
has a 9 pin serial port, to the computers USB.
The manual for the KIO2 says you can use a 24 pin to 9 pin adapter, but it
does not mention connecting to USB. Since the cable is so specialized for
the KIO2 to K2 can I connect it with the 9pin to USB prolific cable? I
don't want to short anything out etc...

Thanks and 73,
Tom Bewick, k2bew

Re: KIO2 RS-232 to USB?

Hi, Tom -

I don't have the specific DB9 to USB adapter that you have, but do this one:

https://www.startech.com/Cards-Adapters/Serial-Cards-Adapters/1-Port-USB-Serial-RS232-Adapter-Cable~ICUSB2321F

which I use with both the KIO2 as well as the DB9 port on the KPA100 and it
works great.

From what I've read, the FTDI chipset, which the Startech product
implements, is the best choice in this application.

Best -

From experience I find the units from R T Systems are 100% reliable. Much more so than the office supplies, electronics stores, Walmart and such. Plus if you have questions, a phone call allows one to speak with a real person in the USA.

Be absolutely sure to use the cable as described in the K2’s KIO2 manual to connect the K2 to the USB adapter. Using a straight-through cable will cause damage to the K2.

Also a lot of people have issues with Prolific chipset USB cables, especially on Windows 10. The cables with FTDI chipset are much more reliable.

Re: KIO2 RS-232 to USB?

Thanks for all the feedback. Yes, I built the cable that came with the it
and I am definitely going to use it put the 9 pin to USB on the end of it,
I know you cannot any other 9 pin cable.
Also I will get a proper cable with a good chipset to take it to USB.

Re: KIO2 RS-232 to USB?

In reply to this post by K2bew

Tom,

Do NOT connect a standard serial cable or a USB to RS-232 adapter to the
K2 (KIO2) AUX IO connector. Note that it is labeled AUX IO and NOT
RS-232. It contains internal K2 signals for external Elecraft gear such
as the KAT100, KRC2 or the XV series transverters.

Build the special K2 to PC cable if you have not done so already, and
connect it to an RS-232 port on the computer. If you do not have RS-232
ports, then you will need a USB to RS-232 adapter. Those with an FTDI
chipset such as the Elecraft KUSB work best. Those with a prolific
chipset are problematic.

73,
Don W3FPR
