UEI-RSS Serial Server Makes PowerDNx Serial Devices Accessible as Standard Windows or Linux Serial Ports

Walpole, MA - United Electronic Industries (UEI) is pleased to announce the release of the UEI-RSS Serial Server. The new software makes UEI's popular line of PowerDNx DNx-SL-501 and DNx-SL-508 devices accessible as standard Windows or Linux serial ports. The serial server allows up to 255 serial ports to be controlled by a single PC over a single Ethernet port. The new RSS not only allows users to expand the number of standard serial ports available on a single PC, it also allows these ports to be mounted remotely. Using UEI's standard chassis, the ports may be located up to 100 meters from the host; while utilizing the Fiber interface cubes, the serial ports may be up to 20 kM from the host. The UEI-RSS Serial Server is included with the purchase of UEI's DNx-SL-501, and DNx-SL-508 devices.

The setup and operation of the UEI-RSS is quick and easy, allowing the user to install the application, assign devices to ports, and save configurations in a matter of minutes. The status window displays each port's status and incoming/outgoing traffic. Status for each port is updated once a second. The UEI-RSS runs as standard communications ports in Windows XP, Windows Vista, and Windows 7 (32- and 64-bit), and Linux.

With the UEI-RSS Serial Server, UEI continues its mission to provide the most innovative data acquisition and control solutions in the marketplace.

About the "Cube"
UEI's powerful "Cube" architecture is a compact (4 x 4 x 4" or 4 x 4 x 5.8") Ethernet-based I/O platform. It may be deployed in five configurations: 1) Ethernet I/O slaved to a host PC, 2) Stand alone Data Logger/Recorder, 3) Linux-based Programmable Automation Controller (UEIPAC), or 4) Simulink / RTW target (UEISIM), 5) Modbus TCP based I/O slave (UEI Modbus). Each Cube consists of a core module (with processor and network interface) and three or six open I/O slots. Users select the deployment option and I/O boards that meet their system requirements. With over 30 I/O boards available, there's sure to be a configuration to meet any application requirement. A six-slot Cube provides up to: 150 analog inputs (up to 24 ICP channels), 192 analog outputs, 288 digital I/O, 48 counter or quadrature channels, 72 ARINC-429 channels and/or 24 Serial or CAN-bus ports. A full description of the "Cube" is available at

About the RACKtangle
The RACKtangle I/O chassis offers a similar capability as the cube, but in a more conventional, 3U rack form factor with easily accessed front-loading I/O boards. In addition, it offers 12 I/O slots and supports up to 300 A/D (including up to 48 ICP channels), 394 D/A, 576 DIO, 144 ARINC-429 or 96 CAN or Serial I/O ports. The Gigabit interface also provides two independent ports, one used for primary system control and the second used for real-time diagnostics. The HalfRACK chassis is the same except with 6-slots.
