Operation Modes Two modes of operations: Mode 1: Check cables without details: does NOT require other devices (PC) Using a simple push putton, following the steps described on the label, after the first short press, the DB 9 connector check start. The related green LED starts to blink: after the cable test if is passed, the LED reamain in ON state, otherwhise the LED is starting to bilnk fast. At the next short press, the DB 25 check is starting and the results are visible on the associated LED, blinking if failed, ON if check is passed. Mode 2: Check cables with detailed informations, it requires a lan connection and a telnet terminal. It works with push button AND with these commands: ?
