PCI Express Digital I/O Cards with Counters and COS Detection
PCI Express Digital I/O Cards with Counters and COS Detection
PCIe-DIO-24D/DC/DS/DCS
This product is a x1 lane PCIe DIO board available in four models ranging from basic DIO to advanced COS detection and Counter/Timer capabilities. The card emulates an 8255 compatible chip, providing 24 DIO lines. The DIO lines are grouped into three 8-bit ports: A, B, and C. Each 8-bit port is configured via software to function as either inputs or outputs. Port C can be further broken into two 4-bit nybbles via software and configured as either inputs or outputs. Each DIO line is buffered and capable of up to 32mA source/sink. The VCCIO logic level is globally configured via jumper selection as 5V, 3.3V, 2.5V or 1.8V. Also, ports A, B, C low nybble, and C high nybble are individually software selected as pull-up or pull-down through 10kΩ resistor networks. The last configured pull-up/down state is stored in on-board non-volatile memory and automatically applied at the next power up. The board is shipped factory default as pulled-up. I/O wiring connections for this board are via a male 37-pin D-sub connector. A ribbon cable can be used to connect this card to termination panels.
