Functional Description　

The PIO-D24 provides 24 TTL digital I/O lines. The PIO-D24 consists of three  8-bit bi-direction ports. The 8-bit port are named port A (PA), port B (PB),port C  (PC). All port is configured as inputs upon power-up or reset. The PIO-D24 has one D-Sub connector,.  It can be installed in a 5 V PCI bus and can support truly "Plug & Play".

The PIO-D56 provides 24-bit bi-direction digital I/O and 16-bit digital inputs and 16-bit digital outputs. The 24-bit bi-direction digital I/O use 37-pin D-sub connector. The 16-bit digital I/O use 20-pin header.
