Series KUSB-3100 USB-based data acquisition (DAQ) measurement solutions are an alternative to ISA, PCI and PCMCIA data-acquisition cards. The compact DAQ measurement tools offer easy installation with plug-and-play capability and easy portability. Using USB as an interface for data acquisition lessens the dependence on PC motherboard technology where slots for plug-in boards are required. Consists of five different multi-function modules that cover a broad range of applications.

Users can install a module without cracking open a PC to add a board, configure DIP switches and IRQ settings, or search for the correct device driver, then reboot the system. Units connect to USB ports on a PC via a standard cable. The PC automatically identifies modules and installs the necessary software to operate the unit.

Can be installed or removed while the computer is running. Offer lower noise sensitivity than PC plug-in boards. Most provide a 500V isolation barrier from the PC, protecting the computer and the input device from damage caused by voltage spikes, surges or shorts. This protection also prevents the computer operating system from shutting down.

Support USB full-speed data rates, for data acquisition sampling rates as high as 100 kHz. Model KUSB-3116 is fully USB 2.0 compliant, providing functionality at the 480 Mbits/sec data transfer rate. Customers can perform multiple I/O operations simultaneously at throughput rates up to 500 kHz in each direction. KUSB-3100 modules are powered directly from the USB port via the USB cable or through a simple connection to an external power source.

Check Plot Online is a PDF preview tool that provides engineers with an accurate, convenient view of circuit board designs prior to production.

"Traditional Gerber viewers don't always show the actual manufactured image
without time-consuming setup," said Ron Huston, founder and CEO. "Our new PCB Check Plot Online delivers an accurate representation of the final design, allowing engineers to avoid costly redesign efforts and project delays once a circuit board moves into the manufacturing phase."

Engineers upload Gerber files to the FreeDFM.com Web site and receive feedback within minutes. The feedback highlights potential design for manufacturability problems and suggests modifications. The free service requires no commitment to order.

Tough, lint-free UltraClean #810B SmartWipes offer the cleanroom-grade quality and cleaning performance of #810, but cost less because they are bulk-packaged by machine rather than hand-stacked. The Class 100 grade polyester wipes offer a range of industrial cleaning applications with extremely low particle generation and soluble extractables. Have good absorbency, resistance to tearing and softness; clean aggressively but will not scratch surfaces. Manufactured from 100% continuous filament polyester fiber with a knit construction and pattern, become softer when wet, while maintaining high tensile strength. Unaffected by solvents, generate very low electrostatic discharge.

Measure 9 X 9", meet Federal Standard 209D and are laundered and dried in a cleanroom environment.
