The United Electronic Industries DNR-12-1G Series RACKtangle I/O Chassis are compact (3U), rugged Ethernet I/O racks. Though the backplane electronics are identical to the PowerDNA
Cube series, the DNR-12-1G Series RACKtangle I/O Chassis provides two Gigabit Ethernet (100/10 Base-T compatible) interfaces and slots for up to 12 I/O boards. Front-loading slots allow the I/O boards to be quickly and easily installed and removed. These capabilities dramatically increase performance and simplify system reconfiguration when necessary. The backplane within the rack contains no active electronic components, ensuring the rack itself has an almost unlimited MTBF. It also means that all active components are on easily replaceable I/O modules, offering an extremely short MTTR in critical applications. DNR Series I/O boards are electronically identical to the DNA boards developed for use in UEI's I/O Cubes. The DNR-12-1G Series is supported by a complement of I/O boards. The DNR-12-1G Series RACKtangle I/O Chassis is ideally suited for a wide variety of industrial, aerospace, automotive, and laboratory data acquisition and control applications.
The bulk of the rack is dedicated to the I/O slots. Options for the I/O slots include: analog input boards to measure voltage, current, strain gages, thermocouples and more, analog output
boards with outputs to ±40V or ±50 mA, digital I/O interfaces for logic and "real-world" signal levels, counters and timers, quadrature encoder inputs, and communications interfaces for ARINC-429/453/708/664, MILSTD-1553, RS-232/422/485 and the CAN bus.
A variety of Ethernet based communications "modes" provide the interface between the host PC and the DNR rack. Largely transparent to the user and fully compliant with standard Ethernet operation, these communications modes have been optimized for certain application types. The first is simple, single point, programmed I/O. This mode is simple and is suitable for most systems where high speed or precise sample timing are not required. The second mode is the ACB (Advanced Circular Buffer). In ACB mode, data is written to and from buffers on the I/O boards rather than directly to the Ethernet port. ACB mode is preferred for high speed acquisition/control or where precise timing is required, as the buffers are large enough to ensure data is not lost due to Ethernet timing latencies. The third mode, is DMAP. In DMAP mode, cubes use DAQBIOS Ethernet protocol to ensure deterministic real-time performance and achieve sub-millisecond response times across more than 1000 I/O (analog and/or digital) points. Finally, there are two high speed messaging modes that allow real-time performance when transferring data to and from any of the communications I/O boards (e.g. the ARINC-429 or CAN-bus interface).
The DNR-CPU-1000 United Electronic Industries Replacement RACKtangle CPU Module may still be available for purchase and support from Artisan Technology Group beyond End-Of-Life (EOL) by the manufacturer (OEM).
