Planning Guide
Introduction
The information in this section is an overview of the Trinix Digital Video
router; as well as a guide to help understand the Trinix Routing switcher’s
configuration possibilities.
If you are installing the router at this time, please read this section before
reading the Hardware Installation section.
The details that are needed for the planning and designing of your facility
with the Trinix router in mind are included in this section.
The beginning of this section includes the conceptual descriptions and
drawings for those who need a basic understanding of the product and its
configuration options. Later subsections provide additional detail such as
connection diagrams and ordering information.
Grass Valley recommends that you terminate all unused outputs. Properly
shielded 75-ohm terminators or spare infrastructure coax cables should be
used. This step will ensure EMC compliance. Spare BNC panels that are not
connected to boards do not need to be terminated.
Grass Valley recommends that the cable lengths be no less than 10 Meters
(32.8 Feet) when re-entering the Trinix routing switcher through 3Gb/s
Input boards. This length does not apply to HD and SD operations.
