Headset Jack Ring-Out Tool — LEMO® 6-Pin ANR Multimeter Adapter (6-Position, Dongle Style)

Chasing a dead ANR, mystery hum, or no-mic drama? Before you start pulling trim, plug this electrical troubleshooting dongle into the 6-pin LEMO panel jack and let your meter call the shots—quick checks up front can help you avoid tearing out interior just to test.

What it is

• Dongle w/ integrated LEMO 6-pin plug: Short, flexible lead with a solid LEMO plug at the end—easy on the jack, easy in tight panels.
• 6-position selector switch: Click through the usual suspects—Mic Hi, Mic Lo, Phones L, Phones R, Phones Return/Shield, ANR Power/Return (continuity only)—one at a time for clean, isolated checks.
• Multimeter-ready: Single 4 mm banana port sized for Whiskey Victor Tools meter leads. Set your DMM to continuity/ohms and start beeping.
• Compact & labeled: Lives in the top drawer; crisp legends so you don’t test the same line twice.

Why you’ll like it

• Targeted electrical checks at the jack: Confirm mic, phones, and ANR power line continuity (power OFF) before you chase wiring down the cabin.
• Find the fault fast: Jack, line, splice, or feed—narrow it down in minutes.
• Shop-floor simple: Beep = good. No beep = problem. That’s the plot.

Quick start — ring-out in minutes

1. Master OFF. (Silence is golden—and safe.)
2. Plug it in: Seat the LEMO 6-pin fully.
3. Hook up your meter: Lead into the 4 mm banana; set to continuity/ohms.
4. Find your audio panel: Locate the other end of the wire and adapt using Walts Avionics D-Sub adapters and long reach tool.
5. Click the switch: Each position isolates one conductor—verify mic, phones L/R, return/shield, and ANR power/return continuity (again, power OFF).
6. Log it & fix it: Beep good? Move on. No beep? You just found your next direction.
