VL21 Description
The Rand McNally Vehicle Link VL21 ELD records driving and on-duty time for FMCSA-compliant logging. Plug the 9-pin J1939 connector to the ECM and run logs on Android.
It switches between On Duty, Driving, Off Duty and Sleeper Berth automatically, completes inspection reports and trip sheets electronically, and shows on-screen alerts for potential HOS violations. Adapters are required for OBD-II or 6-pin ports, and a subscription is required.
