Omega Engineering PCI-DAS1200 manual ORFN3&,$LDJUDP6

1.0 INTRODUCTION

The PCI-DAS1200 and PCI-DAS1200/JR are multifunction measurement and control boards designed to operate in computers with PCI bus accessory slots. The difference between the boards is that the analog ouput functions are not supported by the /JR board. The architecture of the boards is loosely based on the original CIO-DAS16; the standard of ISA bus data acquisition. Much has changed though, and all of it due to improvements in technology. Surface mount packaging technology and custom ASICS allow a far greater range of control over programmable options, such as calibration, triggering, synchronization, and data transfer.

Even the connector has changed. New, denser connectors allow up to 100 signal lines where 37 was once the standard.

The PCI-DAS1200 and PCI-DAS1200/JR are completely plug-and-play. There are no switches or jumpers on the board. All board addresses are set by your computer’s plug-and-play software.
