Serial/CAN Boards

The serial interface remains one of the most popular communications interface in industrial electronics. Though Ethernet, USB and a variety of other interfaces are gaining ground, RS-232, RS-422 and RS-485 remain as real workhorses in the industrial and laboratory markets.

Installed in PowerDNA Cube connected to a desktop, industrial, or notebook PC running Windows 2000/NT/XP/Me/9x, you can use DNA-SL layers for a variety of serial I/O applications, including; controlling instruments, connecting to human interface devices (e.g. printers, keyboards, monitors, etc), monitoring production processes, and interfacing to existing control and DAQ equipment.

Controller Area Network (CAN) is a multicast shared serial bus standard, originally developed in the 1980s for connecting electronic control units (ECUs). CAN was specifically designed to be robust in noisy environments and can utilize a differential balanced line like RS-485. It can be even more robust against noise if twisted pair wire is used. Although initially created for automotive purposes (as a vehicle bus), nowadays it is used in many embedded control applications (e.g., industrial) that may be subject to noise. Bit rates up to 1 Mbit/s are possible at networks length below 40 m. Decreasing the bit rate allows longer network distances (e.g. 250 kbit/s at 250 m).

DNA-CAN Boards are designed to meet the physical and electrical requirements for in-vehicle (automotive) networks based on CAN. Installed in PowerDNA Cube connected to a desktop, industrial, or notebook PC running Windows 2000/NT/XP/Me/9x, you can use DNA-CAN Boards for a variety of CAN applications, including automotive testing and diagnostics, prototype design, factory automation, and machine control.

UEI’s CAN interfaces are supported by the powerful UEIDAQ Framework which includes support for all popular operating systems and application languages including LabVIEW and DASYLab.

Counter/Timer Boards

Counters and timers are very common components in data acquisition and control systems. Our PowerDNA boards (layers) support a complete set of counter/timer functions including: Event counting, Frequency measurement, Pulse-width measurement, Frequency generation, Pulse and PWM generation. In addition to these standard counter/timer modes, PowerDNA boards (layers) are also available to read data from Quadrature encoders.

Avionics Boards

ARINC 429 is the avionics data bus standard used on most high-end commercial aircraft. The standard defines both the physical and electrical interfaces of a two-wire data bus as well as the data protocol to support an aircraft’s avionics network.

The DNA/DNR-429-5xx series is a family of ARINC 429 communications interfaces. The current family includes two different versions with different combinations of TX and RX channels. The DNA-429-566 offers 6 TX / 6 RX while the 429-512 provides 12 RX channels. All boards are fully compliant with the ARINC 429 spec and support both high speed (100 kHz) and low speed (12.5 kHz) operation. The channel speed is software selectable in banks of either two or three channels. Data integrity, even when all channels are set in high speed mode is assured with the use of 256 word FIFOs on all RX and TX channels

All of the DNA-429-5xx series boards are fully supported by UEI’s wide variety of software drivers and programming tools.

Power Supplies

When configuring an I/O Cube, users can choose from these layers to add the ability to generate voltages to power external devices locally. Three models with different voltage levels (±15V, +24V and ±45V) suit most industrial application requirements.

These models offer an isolated DC/DC converter, overload protection, overtemperature shutdown, and a software controlled on/off switch.
