Wi-Fi Module For Machines

Posted on April 21, 2014

In an effort to make machine diagnostics and serving simpler, HED Inc. has developed the CL-T04 CANect Wi-Fi module designed to allow data from a vehicle or off-highway machine’s CAN system to be accessed by any device that has Wi-Fi capability and the capability to connect to a web browser. Using a smartphone, tablet or laptop, the user can accomplish a range of tasks, including viewing live vehicle data, setting vehicle parameters, reprogramming vehicle control software, viewing historical data and trends for prognostics, etc.

The Wi-Fi module is able to link the vehicle CAN bus, via two CAN ports, with an HTML website that is hosted locally on the module. Vehicle data can then be pushed to a secure server via a mobile hotpot or router.

The CL-T04 module is equipped with a powerful 32-bit Freescale Cortex A8 ARM processor running a Linux operating system. The open-source based Linux OS and HED’s SDK allows OEMs to develop their own HTML 5/ PHP based website to be hosted locally on the module.  The IP-67 waterproof module can be mounted anywhere on the vehicle and the internal Wi-Fi antenna provides an operating range of up to 200 ft. from the machine, HED said.
