[GreenKeys] USB to RS-232

[Ralph Irish]

A few weeks back, I decided to see if I could get back on packet radio.  There is a system in downtown
Detroit, just sitting there, waiting for business.  Sadly, it has no internet connection as it once did,
but is still in a good location with decent 'altitude' for the antennas.

I asked a local computer repair guy if he knew of a way to convert an RS-232 signal to a USB connector
without extensive use of software drivers?  He spent a few minutes on the internet and found a cord/cable
device for a few bucks.  It is a 30" cable with a USB connector on one end and a DB9F on the other.  Also
included was an adaptor that allowed one to use an RS232 signal emerging from a DB25 connector.  I've not
yet tried it.  I'm assuming that inside the DB9 connector is some electronics that convert the signals as
needed.

I'm not familiar with the manufacturer (China) but here are all of the details from the package:

SKU OC-1061-US   
SIENOC USB to RS@#@ DB9  le Converter Cable 2.5ft

So, this might be the proverbial 'quick and dirty' way of putting that old PK-232 back into service with
a computer that has no RS232 connector.

If there are any questions, I can't answer them, at least at this time.

My next chore is to see if I have any Mac software in the house that will work on much later Operating
Systems.  I may not be out of the woods yet!

In their early work life, I used them for machine interfaces as many older PLC’s and other industrial controllers used RS-232.  I’m looking to the future when batteries die or other failures of these PC’s.  I have replaced the hard drives in both of these already and no telling how long parts will be available.
