Low-Cost Lab DIO Boards

For applications that involve a high number of digital points, UEI offers three lab PCI digital I/O boards in the PDL-DIO family with 64 I/O lines. Instead of following the industry trend of implementing discrete I/O with cumbersome and limiting 8255-type devices, we work with 16-bit line drivers under control of a DSP and custom logic.

As a result, you no longer need to create external circuitry to guarantee power-on startup states; our software allows you to configure startup states in groups of 16-bit ports. You no longer need to design separate interrupt circuitry; our hardware comes with four high-speed interrupts waiting for you to use. The digital I/O lines are protected against electrostatic discharge and automatically detect shorts on power up.

Besides digital I/O, the board features three 24-bit counter/timers as well as two high-speed ESSI (Enhanced Synchronous Serial Interface) ports. The onboard DSP and optimized PCI-bus interface also allow the card to optionally stream digital data to or from disk at rates as high as 2 MB/s and count events up to 16.5 MHz.

The PDL-DIO can be configured for 16- or 32-bit pattern I/O. It supports change detection, handshaking lines to clock parallel digital I/O and externally clocked pattern generation.

Distribution panels make all the board's I/O capabilities available for field connection. Further, an optional accessory (PDL-DIO-CONN64-4) distributes the 64 digital I/O points into four sets of 16 lines through industry-standard 50-pin IDC connectors. They, in turn, attach directly to relay panels available from UEI and many other sources.

The PDL-DIO is ideally suited for OEM applications. Optional SDRAM and firmware development kit allow customers to develop their own DSP code based on examples provided in the SDK or use this memory as a buffer for I/O operations.
