How do I know if a cable is faulty?
The LED lights will indicate pin continuity issues, including open pins, shorts, or swapped wires.
How can I confirm the tester is working before testing my cables?
Connect the Sniffer and Sender directly to each other—this should light up all LEDs. If LED A does not light up, the battery may be low. Replace the 23A 12V battery and test again. If the issue persists, reach out for further troubleshooting.
How do I use the Cable Matters XLR Sniffer/Sender?
Connect the Sender and Sniffer to each end of a 3-pin XLR or DMX cable. The LED indicators will show if the cable is wired correctly or has faults.
What battery does the tester use?
It uses a 23A 12V battery, which is included for immediate use.
Can I use this tester with 5-pin DMX or other cable types?
No, this tester is designed for standard 3-pin XLR and DMX cables only.
