Digital I/O Cards
The circuits use an 82C55A PPI with mode 0 supported. Ports A, B and C are buffered with 74ABT245 transceivers and pulled up to 5V.
The optional 82C54 has three-sixteen bit down-counters within one chip. These counters are useful for making frequency outputs, measuring frequency of square waves, pulse width outputs, pulse width measurements etc. Software drivers are provided on CD.
Modified-COTS (MCOTS) Customization
ACCES can tailor any standard product to your precise requirements — electrical, mechanical, firmware, environmental, or connector-level. Common MCOTS options include alternate I/O ranges, isolation enhancements, firmware changes, private labeling, conformal coating, extended temperature operation, ruggedized enclosures, and military-grade components. If this product is close but not a perfect fit, our engineering team can deliver a rapid-turn MCOTS variant with minimal NRE and dependable, Made-in-USA quality.
