The OME-PIO-D24U provides 24 TTL digital I/O lines. The OME-PIO-D24U consists of three 8-bit bi-directional ports. The 8-bit ports are named port A (PA), port B (PB) and port C (PC). All ports are configured as inputs upon power-up or reset.

The OME-PIO-D56U provides 24-bit bi-directional digital I/O, 16-bit digital inputs and 16-bit digital outputs. The 24-bit bi-directional digital I/O uses one 37-pin D-sub connector (CON3). The 16-bit digital I/O uses two 20-pin headers (digital inputs on CON2 and digital outputs on CON1). The 20-pin digital I/O headers can be extended to the PC slot window by using the OME-ADP- 20/PCI adaptor. The OME-PIO-D24U has one D-sub connector only. It can be installed in a 3.3 V or 5 V PCI bus and supports true "Plug & Play."
