IDC cable tester (Arduino based)

This is a IDC cable tester is more advance using Arduino Mega board. IDC cable is often also known as ribbon cable or flat cable. Typically the adjacent wire to wire pitch is 1.27mm.

This project comes with a big Alphanumeric display to test the cable without needing the tester connected to a computer.

Using only a simple 555 timer and 4017 IC chip. Very similar to the one above.

Another same project replicated by another electronic hobbyist.

IDC Ribbon Cable Tester circuit

This is a less complicated IDC cable tester with using any microcontroller. Simple circuitry that can check for connection and short circuit in your IDC cable.

There is also an explanation of how the circuit works. This can give you a more detail understanding of designing your very own cable tester.

PIC Cable Tester
Schematic for PIC Cable Tester

PIC Cable Tester

This network cable tester (PIC Cable Tester) uses microchip microcontroller PIC16F877A.

It comes with two RJ45 socket and can identify common Ethernet patch cable or cross cable. The design comes with LED indicator for the display of the connection.

Report of the cable connections will be generated and display on the LCD display screen.

Schematic and source code is available.
