[WORKED!!!] Connecting TDS210 to computer via RS323 serial to USB
gkmaia:
I am trying to connect my TDS do my MAC via a RS323.
So far my MAC can find something is connected via USB serial.
TDS has been configured to hardcopy via RS323. But when I press HARDCOPY no data comes through. Has anyone successfully achieved that?
I tried to scope the pins on my RS323 to see if I could find any trace of TX or RX flowing but found just low amplitude noise or ground. And then maybe see if my cable was set wrong. Did try that on my TDS210 and TDS220 both with their on expansion cards.
Video bellow shows my usb/serial cable getting data from my signal generator and sending data to my scope. So far the cable is working fine.

I finally managed to get data out of my old TDS210!!!!
If anyone needs to do the same here is my setup. Costed $5.
You will need to tweak the serial cable and connect pin 3 of the scope RS232 to pin 2 of the usb/serial cable if you get a male DB9. I have ordered a female one and will check if pins lineup when it arrives.
You should get a file on terminal like the calibration.txt bellow. Just add the .eps to the text file and convert it to an image on https://www.epsconverter.com/

Just moved it.
Maybe not a great achievement but it is cool anyway to get my old TDS talking to my computer.
