Introduction

General Purpose Inputs/Outputs (GPIO) consisting of simple relay contact closures, is still of common use in Broadcast facilities. In some cases, a certain "logic" is desired between some GPIs and GPOs. The system presented here, GP-LOGIC, provides the means for doing that by allowing the user (engineer) to define that logic in terms of Boolean expressions.

Since we are not manufacturers, GP LOGIC will be provided as a kit: separate pieces that engineers need to put together and configure according to their needs. This manual provides all the information engineers need for successfully deploying and configuring a GP LOGIC system in their Broadcast facilities.
