8440
CAN, GPS
Overview
The 8440 card supports both simple monitoring, where messages are read and logged from the bus, and PID mode, where automatic PIDs can be requested under user control. CAN Bus gives the flexibility of access to the tens or hundreds of parameters that are already present on an automotive vehicle or even modern aircraft communication bus.
The 8440 card supports two separate independent CAN Bus inputs for dual system monitoring and capture.
A GPS option is available so that position, velocity or accurate wall clock time can be recorded with the data. Further there are GPS options that have different specification depending on the customer’s requirements.
