Simultaneously Acquire Network and Direct Sensor Data

A hallmark of DAWN is that it simultaneously acquires several types of data including GPS, CAN bus, and direct sensor data. Acquiring sensor data is needed to overcome any limitations of the network because the data is either too slow or the network does not have the required information.

The analog sensor data is acquired using the A/D converter on the same box that acquires the other data. Another option for sensor data is to have a separate CAN instrumentation network where the sensors’ signal conditioning also has an A/D that outputs CAN data which is acquired on a different CAN port (channel) than the in-vehicle network.

A third option is to use one of the 200 models of A/D hardware that Snap-Master supports. You have several interface options to the PC including USB, Ethernet, or PCI as described in the I/O hardware section. If you already own hardware listed in the Analog I/O section then you can use it with DAWN. Some network interface hardware also has 6 to 16 channels of analog hardware.

With Snap-Master’s instrument window and icons representing elements it is easy to define the functionality you need. Acquire either network data, analog data, or both simultaneously. Also compare newly acquired data to some reference data to perform pass/fail testing.
