Cable Testers

About

This cable tester is designed to evaluate if a USB-C to USB-C cable connection works properly.  The cable tester verifies that the internal connections used to transmit and receive power & data at both ends are working properly.  This test will identify faults in the connection associated with specific components of the internal construction and wiring.

How to Use

Interpreting the Results

Simply connect the cable at both ends using the tester’s USB-C ports on the left and right sides.

It is important to note that a cable operating normally will not illuminate all LEDs.  Non-illuminated LED’s do not necessarily indicate a failed cable.

A properly working cable will illuminate all lights except for the D+ and D- pair in one column. This can be on the left or right column as shown below.

TetherBoost Pro USB-C Core Controller Extension Cable + TetherPro USB-C to USB-C cable:

First, test the standard USB-C cable alone in order to confirm that the cable is working properly.  Once confirmed, insert the TetherBoost Pro USB-C Core Controller Extension Cable between the tester and the standard cable that has been confirmed to work properly.  The TetherBoost Pro USB-C Core Controller Extension Cable can be connected on either side of the tester.

A properly working cable will illuminate GND (x2) and VBUS (x2) in both columns, CC1, CC2, D+, and D-. This can be on the left or right column as shown below.

The following conditions DO NOT indicate a cable fault.

• When testing the CUC15 Cable, D- and D+ will not illuminate on one side.  This is normal and does not indicate a fault in the cable.  A working cable would exhibit the D- and D+ LEDs illuminated on one side, and not on the other.
• When testing some cables, particularly the TBPRO3, some lights will be faintly illuminated.  This is normal and does not indicate failure.
• Rotating the cable connector 180º on the left side of the tester will flip the symmetry of the lights.

How to replace the battery

The cable tester uses a CR2032 battery.

To replace the battery, use the following instructions:

1. Open the case using the included Hex key to remove the hex screws in the top left and bottom right corners.

2. Remove the top portion of the case

3. Remove the battery by sliding it to the right out of the battery bracket.

4. Insert a new CR2032 battery with the positive contact (+) facing up.

5. Realign the top portion of the case and retighten the hex screws.
*Note, do not overtighten!  Tighten the screws until the top case becomes flush with the bottom portion.  Overtightening will crack the exterior of the case.

Note: The tester does not consume power while not in use
