*** This product has been phased out and replaced by PIO-D48U ***

The PIO-D48 provides 48 TTL digital I/O lines. The PIO-D48 consists of six 8-bit bi-directional ports. The 8-bit ports are named port A (PA), port B (PB), and port C (PC). Port C can be split into 2 nibble-wide(4-bit) ports. All ports are configured as inputs upon power-up or reset. The PIO-D48 has one D-Sub connector and one 50-pin flat cable connector. Each header can be connected to a 50-pin flat cable. The flat cable can be connected to the ADP-37/PCI or ADP-50/PCI adapter. The adapter can be fixed on the chassis. It can be installed in a 5 V PCI bus and can support true "Plug & Play".
