To answer your question, you can read the data on your PC using the
hyperterminal utility under Programs Accessories Communications.
You will need a serial cable and working COM port.

You are only interested in 2,3,5 on a 9 pin connector.

gives a picture. You can get an RS232 to USB cable for anywhere in the
range of $7 to a Belden at about $30. I got one at Fry's of the $7 variety
last year to run to my Garmin 162 for firmware and map uploads from the
laptop. IF no data coming in swap 2 & 3. A few years ago we got PCMCIA
RS232 comm cards for a project I worked on. the USB are cleaner and nicer
and cheaper. If you have an older PC they might still have a comm port.

Hmm. Nema only has 2 (data & common) common is, much of the time, just ground.

For instance, Garmin GPS has only 2 wires for NEMA (data IN and data OUT) --
you use ground for the common)

SO if I want to READ data, I'd just use 2 & (5 or 9)?

Thanks
