PB-SIO4A Introduction

ID 19958, Rev. 0300Page 1 - 4 ® PEP Modular Computers GmbH

This piggyback is fitted with DUART devices (two driver/receiver devices each handling

two of the four serial channels), as well as a GAL device containing the specific interrupt

handling logic and other features such as the I.D. number.

The optoisolated versions have eight optocouplers which are replaced with wire bridges

on the non-optoisolated versions.

For operational configuration of this piggyback there are solder jumpers located both on

the front and rear side of the board.
