The Sealevel Systems’ PIO-48 digital I/O interface is designed around two 8255 chips, each providing 24 I/O lines. The board has a Dip-switch for flexible I/O addressing, IRQ jumpers for interrupts and two sets of connectors for each port. A standard 50-pin solid state relay I/O module connector and a 40-pin connector with power and IRQ signals is provided. The 50-pin connects (through an optional cable) to industry standard PB-8, -16 or -24 solid state relay I/O modules. The 40-pin connector, terminated in an optional DB-37 cable, matches the pin-out of “Generic” PIO-12 boards. By using the PIO-48 with two of these cables, you can get two times the I/O of the PIO-12 on one board. Also provided is a software interface that allows you to set, reset, examine or monitor any bit or I/O line. Our SeaI/O Family of Windows 98/ME/NT/2000/XP and Linux Software drivers isc included along with sample applications and utilities for rapid application development. |
