DAQ: Board, interface help with data acquisition


United Electronic Industries (UEI) released DNA-SL-501 serial I/O layer/board. The new board offers 4 independent, isolated RS-232, -422, or -485 ports with maximum data transfer rates up to 1 megabit/s in RS-422/485 mode. Ports are fully configured with software, and different ports may have different configurations. UEI also announced new hardware synchronization interface for the PowerDNA (Distributed Networked Automation) cube that allows data acquisition (DAQ) applications to be initiated by or clocked by user-supplied digital signals. The new interface allows multiple cubes to be synchronized with each other.

"The PowerDNA Cube has been very popular in a wide variety of DAQ applications. Many of these applications also have the need to interface to external serial instruments and equipment. The new SL-501 greatly simplifies this interface and is ideal for serial server applications," says Shaun Miller, UEI president. The new sync interface will "allow the PowerDNA cube to address many new timing critical applications."

DNA-SL-501 is priced at $650; the new sync interface is included with PowerDNA cube, an Ethernet-based data acquisition and control device with three or six open I/O slots or layers.
