DAWN Hardware Models
DAWN works with SAE J2534 compatible devices. Combine HEM Data’s feature-rich software with the best hardware for your application. Some hardware is small and wireless, so you can be outside the vehicle and still acquire data with a laptop. Other DAWN hardware units are designed to serve as loggers to start and stop with the vehicle and work over an extended temperature range. These units do not require a laptop in the vehicle.
DAWN hardware models offer a variety of interfaces to the computer, including Ethernet, USB, and wireless. If you already own a J2534 device, DAWN probably works with it so you only need to buy the DAWN software. Let us recommend the best DAWN hardware model based on your requirements.
