Title: Tripp Lite Omni Pro 450 serial cable diode?
Post by: Aristarco on Jan 30, 2019, 16:05
According to the Omni Pro 450 (675) cable pinout, there's a diode going from pin 7 at the female DB9 (PC side) to pin 2 of male DB9 (UPS side). Is the anode connected to pin 7 and cathode to pin 2? Or vice versa?
