NTRODUCTION

 

 

The Trilogy 331-00-xx Mentor CX Changeover Unit is designed to complement the Trilogy RG 

Reference Generator. The Mentor product family is suitable for any digital or mixed format 

environment where a high quality digital SPG is required. Mentor CX provides a manual or automatic 

changeover between a pair of Mentor RG generators, providing the maximum possible security for 

on-air applications. 

 

The following features and facilities are offered: 

 

•

 

Compact 1RU rack mounting package matching the Mentor RG 

•

 

Single or redundant dual power supplies 

•

 

Base Mentor CX provides: 

o

 

4 channels which monitor and switch Black and burst,  

Tri-Level-Sync, AES/DARS, word clock, 10 MHz and 27 MHz 

o

 

2 channels which monitor and switch SDI – SD/HD/3G signals but do not detect or 

report the standard 

o

 

Monitoring and switching of balanced AES and LTC signals 

•

 

Comprehensive range of expansion modules, up to a total of 18 channels 

•

 

Both actively monitored and passively switched channels for a range of signals 

•

 

Front panel control and status indication 

•

 

Vector web management, tightly integrated with Mentor RG provides full setup, monitoring 

and control 

 

In addition, an internal redundant power supply is available to increase MTBF, or to allow AC power 

diversity in critical applications. An Ethernet port is provided for the Vector browser based 

management feature and also facilitates software upgrades. 

 

This User Guide concentrates on the operational aspects of the Mentor CX and includes a full 

technical specification.
