If you suspect a wiring error in a cable or just do not know how the pins are connected, you may show the cable's schematic on your monitor for review. CableEye's software draws this wiring diagram automatically. Use the cursor keys to highlight a connection of interest, as shown in red below. You are looking at an exact screen image from a PC monitor, not a drawing. (additional descriptive text continued below)
The small buttons with red arrows on each side of the drawing show the direction of view into the connectors. In this case, we are looking into the pins of the left connector and the terminations (where the wires are soldered or crimped to the pins inside the connector) of the right connector. Click either button to redraw that connector looking in the opposite orientation.
Quickly alternate the display between the correct schematic
and the faulty one to immediately detect subtle differences in
wiring. Print any of the error displays for hard copy of the faults.
