Flexible Acquisition Timing with “Slow Bits”
It’s not unusual to find boards with channel/gain lists, but for the ultimate in flexibility, UEI allows you to do plenty with the 256-entry list on PowerDAQ boards. For instance, the same channel can appear multiple times in the list, effectively changing its sampling rate compared to the others. In addition, we give you more control over individual channels beyond selecting their order and gain. For example, you can increase the acquisition time for just one channel so as to ensure accuracy at high gains, or to work with a sluggish sensor – without slowing down all the others. To do so, you insert a Slow Bit, which adds a user-configurable delay after a particular entry.

Sophisticated Digital I/O Cards
It’s easy to knock out a digital I/O board using an 8255 or equivalent chips, but do not expect high-speed performance. Using the same DSP technology as our multifunction cards, our digital I/O cards work with 16-bit line drivers that allow you to configure startup states. Also thanks to the DSP, you can employ three counter/timers, four 100 nsec interrupt lines and two Enhanced Synchronous Serial Interfaces that ease interfacing to codecs and other telecom-related devices with high-speed serial I/O streams, a feature you’ll not find elsewhere. Again, as with analog inputs, you can stream digital values to memory or disk at high rates.
