3701 overview

The 3701 PC/104 digital I/O interface module is designed around an ASIC emulating 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. Two standard solid-state 50-pin relay rack header connectors are provided.

Sealevel's SeaI/O Classic software drivers and utilities make installation and operation easy using Windows 98, ME, NT, 2000, XP and Vista operating systems.
