2-about the voltage when measure the voltage coming on pin 2 of RS232 cable I found -10.4v I'm using a Multimeter I'm afraid this is not a valid test at all: Think about what an RS232 signal looks like - how can that possibly relate to a multimeter voltage reading?! Do you have access to an oscilloscope? |
