| (...) OK, well I think it is isolated at the pseudo-MAX232 chip. Did you get the +10 v power supply pin on the p-MAX ok? It's at pin 2. Measure it w/r/t ground and you should get +10v. Before you order a real Maxim, check the polarity of your (...) (28 years ago, 3-Jan-97, to lugnet.robotics.handyboard)

| Here is the relevant part of the test instructions: Finally, the MAX232's ability to transmit data to the host computer is tested. Again using pin 7 of J9 as a ground reference, measure the voltage at pin 3 of J9. This is the MAX232's serial output. (...) (28 years ago, 3-Jan-97, to lugnet.robotics.handyboard)
