PIO-D48SU
The PIO-D48SU supports 3.3 V/5 V PCI bus. These cards provide 48 TTL digital I/O lines, and these lines are grouped into six 8-bit bi-direction ports. Every three 8-bit ports are grouped as port A (PA), port B (PB) and port C (PC) on a connector, and the port C can be split into 2 nibble-wide(4-bit) parts. All ports are configured as inputs upon power-up or reset.
The PIO-D48SU also adds a Card ID switch and pull-high/ pull-low resisters for DI on board. Users can set Card ID on a board and recognize the board by the ID via software when using two or more PIO-D48SU cards in one computer. The pull-high/ pull-low resisters allow the DI status to be specified when the DI channels are unconnected; the DI status will remain in high or low status other than floating.
