#146069 - of course, you need to connect gnd Responding to: ???'s previous message |
if we dont connect GND together then we cant Run the RS232 interface Right!.
of course, you need to connect gnd to gnd, what else would the signals reference to? What exactly you want to indicate. you said "I am connecting both the ground together with a conductor so ground problem isnt a problem." what I "want to indicate" is that connecting gnd to gnd does not guarantee that "ground problem isnt a problem" Erik |
