Physically, the modules can be distributed around the vehicle, making efficient use of available space. The system is easily expanded to include additional channels or features as a project progresses.

Furthermore, there are a range of different module types, each of which can be networked together to form a larger system, or in some cases, the functionality of different modules can be combined into the same module. Below are brief descriptions of each of the main module types:

Input Expansion Module
The Input Expansion Modules feature 8 universal sensor inputs - each input can be individually configured to measure analogue signals, frequency signals or to measure the signal from Stack’s proprietary DSP interface modules. Each input can be recorded at up to 200Hz.

Video & Data Synchronization Module
The Video Modules facilitate video input and data synchronization to a recording device and connects between a remote mounted camera and a digital video recorder, such as the Stack Harsh Environment DVR.

CANbus Gateway Module
The CANBus Gateway module acts as a bridge between a vehicle host CANBus network and the Stack data acquisition system.

Sensor Interface Module
The Sensor Interface Modules have direct sensor inputs for 5 low resolution configurable inputs, a dedicated RPM signal input and 2 pulse inputs.

Display Module
The Display Driver Modules can drive a wide choice of analogue dials and LCD read-outs, allowing up to 7 LCD read-outs modules and 2 analogue dials to be connected.

Recorder Module
The Recorder Module supports a wide range of recording strategies and feature solid state non volatile battery backed up memory - that will not be lost even in the event of a high impact accident.
