Description
I have a bunch of these that were manufactured but they're all DB25. Now days, RS232 Serial connectors are all DB9s. I made one by hand w/ solder DB9's (M/F) connectors with the PCB board pinched between the solder lugs. I don't have a case/labels, so I made sure the LEDs were laid out in the same order/position as my DB25 model.
It answers the questions: (instantly)
1) Do I need a NULL Modem?
2) Is there power on these pins?
