1708Crocodile - Contactless SAE J1708 Bus Reader
Free Shipping Within The United States!
The 1708Crocodile is designed for secure data reading from an SAE J1708 bus (SAE J1587) of vehicles. The contactless reader is used within vehicle telematics and GPS tracking systems for receiving various parameters of vehicle operation from the bus, such as speed, RPM, oil pressure & temperature, fuel volume & consumption, and more.
The data reading occurs without electrical connection and without damaging wires. The 1708Crocodile works in “listen-only” mode, i.e., it does not change original SAE J1708 messages and does not transmit any signals.
All Crocodile contactless readers have a built-in voltage regulator, which allows to power the reader from the on-board electrical network of a vehicle without using any power adapters.

About SAE J1708/J1587
SAE J1708 is a standard used for serial communications between ECUs on a heavy-duty vehicle and between a computer and the vehicle. Regarding the Open System Interconnection model (OSI), J1708 defines the physical layer. Standard higher-layer protocols that operate on top of J1708 are SAE J1587 and SAE J1922. The protocol is maintained by SAE International.

OBD-II & Electronic Engine Management Systems
On-board diagnostics (OBD) is an automotive term referring to a vehicle's self-diagnostic and reporting capability. OBD systems give the vehicle owner or repair technician access to the status of the various vehicle subsystems. The amount of diagnostic information available via OBD has varied widely since its introduction in the early 1980s versions of on-board vehicle computers.
