I am connecting both the ground together with a conductor so ground problem isnt a problem. WRONG that fallacy has killed many a project. connecting 'ground' to ground' through a series of inductors (the equivalent circuit of a wire) is no panacea. Hi Erik if we dont connect GND together then we cant Run the RS232 interface Right!. What exactly you want to indicate. APC |
