The Onyx2 digital video multiplexer (DPLEX) hardware described in this document requires both hardware (primarily boards and cables) and software to be complete.
This guide presents the information necessary to an end user that wants to understand the hardware in an Onyx2 system with DPLEX graphics. Each chapter in the book addresses a particular area, with further refinement at the section level. References are made to external documents when needed.
This guide contains the following chapters:
Chapter 1, “Introduction to the Onyx2 DPLEX Option,” illustrates and describes the DG5 and DPLEX board assembly and provides applicable parts and safety information.
Chapter 2, “Onyx2 DPLEX Cabling Configurations,” uses text and drawings to describe the proper DPLEX cabling scheme for cascades up to eight pipes. Examples of two and three matched DPLEX cascade pairs are also provided.
Chapter 3, “DPLEX Software Configuration and Troubleshooting,” provides information on procedures for enabling or disabling a DPLEX pipe. Hardware configuration commands and other information for checking on DPLEX functions are listed.
Chapter 4, “Onyx2 DPLEX Theory of Operation,” covers basic information on the operational theory of the DPLEX video hardware.
This manual is intended to assist Onyx2 DPLEX option users to
use the DPLEX hardware options properly
understand the correct levels of software required to support the DPLEX options
reconfigure the DPLEX system cabling for different levels of functionality
run an audit of the system to check the DPLEX option graphics
