Every application is different, and ACCES can easily tailor a system to a users specific needs. After listening to our customers, ACCES has developed a system design and integration team focused on the development of powerful, yet simple to use, data acquisition systems. These include extensive CPU and peripheral capabilities and the integration of a generous selection of our (or customer-specified) data acquisition, I/O, or special-function PC/104 boards. Custom development can include minor variations of standard boards and systems to completely custom interfaces and configurations. ACCES has the in-house engineering resources to design, develop, supply and support custom embedded systems at the board, software and system level.
