Whatsminer Signal Cable Specifications

FAQ — Whatsminer 16p-18p Signal Cable

Q: Will it work on newer M50 / M60 series?
A: This cable is specifically validated for M20 / M21 / M30 / M31 / M50 test fixture combinations. M50 / M60 use different connectors and likely need different signal cables. For mixed M20 / M50 fleets, contact us with your test fixture model for compatible cable recommendations.

Q: 16-pin or 18-pin end — which side connects to the hashboard?
A: Verify by counting pins on your existing failed cable's hashboard-side connector. Different test fixture builds use the pinout in different orientations. The cable can typically be installed in either direction electrically — the connector geometry determines fit.

Q: How do I know if the cable matches my test fixture?
A: Before purchase, inspect the plug count and pin spacing against your test fixture's existing cable. Photo verification is the safest approach for non-standard test fixtures.

Q: Bulk pricing for Whatsminer repair shops?
A: Yes — email contact@lys-sz.com with your fleet maintenance volume for tier pricing on multi-cable orders.
