National Instruments Introduces Ethernet Data Acquisition Platform

National Instruments announced the new Ethernet-based NI CompactDAQ modular data acquisition system, which combines the ease of use and low cost of a data logger with the performance and flexibility of modular instrumentation.

The new NI cDAQ-9188 chassis is designed to hold eight I/O modules for measuring up to 256 channels of electrical, physical, mechanical or acoustic signals in a small (25 by 9 by 9 cm), rugged form factor. With more than 50 different I/O modules to choose from, engineers and scientists can build remote or distributed, high-speed measurement systems using standard Gigabit Ethernet infrastructure. In addition, NI CompactDAQ simplifies initial setup with zero configuration networking technology and a built-in, Web-based configuration and monitoring utility.

“We chose NI CompactDAQ because of the flexibility offered by a diverse set of I/O modules and the scalability of Ethernet infrastructure,” said Randy Recob, Senior Test Engineer, Sub-Zero, Inc. “The flexibility of Ethernet allows us to more easily standardise our test systems by eliminating many of the physical constraints required by more traditional PC interfaces. We have used National Instruments data acquisition hardware and software in our test applications for years because of the measurement accuracy, system stability, and ease of use available with their solution.”

• Uses patented NI Signal Streaming technology to deliver high-bandwidth data over Ethernet to a host computer.
• NI Signal Streaming provides the ability to maintain bidirectional analog and digital waveforms continuously over a TCP/IP connection.
• With NI-STC3 timing and synchronisation technology, each chassis also can manage up to seven separate hardware-timed I/O tasks at different sample rates, including analog I/O, digital I/O and counter/timer operations. In addition to the Ethernet chassis, the NI CompactDAQ platform includes a four- and an eight-slot USB chassis and NI C Series I/O modules.
• C Series modules offer integrated signal conditioning and multiple connectivity options to create custom, mixed-measurement systems specific to the needs of an application.
