CANgate User's Manual - dataTaker

Introduction
About CANgate
CAN (Controller Area Network) is a data communication system widely used in the automotive industry.
The dataTaker CANgate allows a data logger (such as the dataTaker DT80) or a host computer to be interfaced to a CAN
network. CANgate is equipped with two standard CAN interfaces, plus a serial interface for connecting to an NMEA-0183
compatible device such as a GPS unit. Data may then be returned to the host computer or data logger via a second RS232
interface.
CANgate is capable of performing a range of functions; such as sending and receiving raw CAN messages or performing
higher-level functions to interface with ISO-14230/OBD-II and SAE-J1939 compatible devices.
The CAN ports are "hot-pluggable" and all CANgate settings are saved in non-volatile flash memory so that the unit will
resume its configured tasks following a power interruption.

About This Manual
This document is primarily a reference manual which describes the commands used to configure the CANgate. It is assumed
that the reader has some familiarity with the operation of CAN-based systems and the various communication protocols
which operate over CAN.
Note that dataTaker DeLogger software provides an easy-to-use "front end" which will generate the required logger and
CANgate commands in order to monitor and record the parameters of interest from the CAN bus. If DeLogger is used then
detailed knowledge of the CANgate commands described in this manual is not required.
