J1939
A family of vehicle-network standards commonly used for communication between commercial vehicle electronic systems.
THE CONNECTION STARTS HERE
Real vehicle data.
A deliberate connection.
An ELD experience starts with the right information from the truck. Hardware, software, and vehicle compatibility must be considered together.

KNOW YOUR VEHICLE
Compatibility is specific.
A vehicle interface is not a universal answer. Vehicle generation, network protocols, connector, firmware, and software support all affect the result.
Assessment should establish which required engine values are available, how reliably they can be captured, and what happens at engine start, shutdown, and disconnect.
Start a compatibility conversation ↗J1708 / J1587
Technologies found in older heavy-duty vehicle networks. A suitable gateway must support the actual protocol and messages used by the vehicle.
Bluetooth
The local transport between a supported interface and mobile device. Wireless connectivity alone says nothing about the completeness of engine data.
Hardware selection requires evidence.
No production hardware compatibility is represented here. NEXIQ Blue-Link 2 is a candidate for evaluation, not a selected or validated production interface. Double M ELD does not claim a NEXIQ partnership.
Any candidate must be assessed as part of the complete system. A diagnostic interface does not independently establish that an ELD meets regulatory requirements.

your operation.
One truck or an entire fleet. Start with what matters to you.
