1.0 INTRODUCTION

The PC104-DI48 is designed to have the best quality and lowest cost of any digital
input board.

The PC104-DI48 conforms to the connector pin specification of all the PC104-DIO48
digital boards and CIO-Dxx48, 96 and 192 family digital boards, so may be used in
place of one another without changing cabling or connectors.

These products are supported by Universal Library programming library.
