The DNA/DNR/DNF-DIO-480 are universal digital I/O boards for use in UEI’s Cube/RACKtangle/FLATRACK I/O chassis respectively. The board offers 32 independently configureable DIO channels that can be set as input our output, and are compatible with everything from 3.3V TTL levels to 55 V industrial signal levels.

Each of the 32 bits may beindependently set as inputor output. When configuredas inputs, the logic levelthresholds may be set with275 mV resolution. Theinputs have programmablepull up/down resistors thatallow inputs to monitorcontacts connected to asupply voltage or ground.Inputs are sensed with a 400kHz A/D converter so highand low voltage thresholdsare programmable andallowing change of statedetection with 5 μsresolution. Digital input datamay be streamed at 200kHz, and to ensure no lostdata the DIO-480 provides a32-bit by 4096 FIFO.

he outputs can be set as current sourcing (a switch between Vccand the output), current sinking (a switch between Gnd and theoutput), push-pull (connect to Vcc or Gnd but not at the same time).The digital outputs can also be configured as flexible controllerswith PWM and 16-bit pulse width resolution or soft-start. ThePWM/soft-start parameters are selectable on a per-channel basis. Theoutputs are protected with 1.25 Amp fast-blow fuses.

The digital input data may be streamed to FIFOs with timestamps. Din timestamps are generated at the start of the scan.

The board is supported by a variety of cable and screw terminal optionscertain to meet the needs of almost all users. For those wishing to create theirown cables, all connections are through a standard 62-pin “D” connectorallowing OEM users to build custom cabling systems with standard, readilyavailable components.

The DNx-DIO-480 is supported by a complete software “suite” includingsupport for Windows, Linux and all popular RTOS. Windows support isprovided by the UEIDAQ Framework which includes a powerful softwareinterface to Windows programming languages and DAQ applicationsincluding VISTAS, LabVIEW and MATLAB. An extensive factory writtensoftware suite is also provided for all popular “non-Windows” operatingsystems including Linux, VXworks, QNX, RTX, INtime and more. All softwaresupport includes extensive example programs that make it easy tocut-and-paste the I/O software into your applications.
