USB to RS232/DB9 adapter

[Julius Fazekas n2wn]

Hi Chuck,

I had similiar experiences with several USB adapters.
It seems to be an issue, not just with the K2, but
other devices as well.

Drivers may help, configuration is important as well.
On my laptop, the default com port was com11. Your
equipment might be looking for a device on a different
com address (ie N1MM looks for com1, but you can set
it for a different port).

Don's point is important to remember, you still have
to use the K2 DB9 cable to interface to the USB
adapter.

I also found many of the multiport USB devices were
useless (or more of a pain to use than they were
worth).

This is what I found that worked (except I can't use
it to send CW via N1MM) with the K2 and my computer:
Tripp Lite U209-000-R Serial Adapter - mini USB Type A
- DB-9 - male . Your mileage may vary ;o)

73,
Julius

I wonder if you laptop can deliver enough current? This is an important
consideration that is often overlooked, some USB chipsets are feeble.

Hi Simon,
Mine is very loosely refered to as a laptop, is more
like a portable desktop (pushing 10 pounds). I also
had problems with two different desktops. According to
our IT group, compatibility is an issue with some of
these.
Cheers,
Julius

G'day,

|I wonder if you laptop can deliver enough current? This is an important

The USB cable that came with a recently bought Iomega external slim-line
hard drive had two PC USB port plugs to a single hard drive plug just in
case a single PC port couldn't deliver the current.

Regards,

Mike VP8NO
