Section 1 — Introduction
The System
The Series 6000 system comprises video, audio and control level (RS422)
routers, all based on the standard block size of 16 inputs to 16 outputs.
Video and audio matrices are housed in separate rack-mount frames
complete with power supply and microprocessor control.
Units are stacked together to provide multiple levels. For example, a
system could be provided with serial digital, composite video, three levels
of component video, four levels of audio, time code and RS422.
Remote control panels are usually supplied as part of a system and these
are connected back to the frames by a single coax
Quick-Link Bus through
each of the frames and remote control panels in the system.
The Frame
The frames are of solid construction and house plug-in modules. The main
router modules — video, audio or control level — are located on the left-
hand side and the power supply module(s) on the right.
The plug-in modules are positively locked in place to prevent them from
coming loose when installed in a mobile vehicle. Yet they can be easily
removed from the front of the frame by removing the front panel/local
control panel and releasing the modules held in place by special quick
release handles. The modules may be removed while the unit is under
power.
Analog Video Routing
The Series 6000 analog video matrix is suitable for wideband applications.
There are two 1RU frames, 16x4 and 16x16. The 3RU 32x32 matrix is built
from four 16x16 modules. These are organized in pairs so that each pair
provides 32x16 (32 inputs to 16 outputs). The pair of modules is bolted
together with connectors between them, and slides into the frame as a pair.
The upper module of the pair is fully loaded but the lower module contains
only the input and crosspoint stages. The upper module of the pair routes
inputs 1–16 and the lower module inputs 17–32.
Two of these 32x16 pairs of modules are used to build up a 32x32 matrix.
The upper pair of modules routes outputs 1–16 and the lower pair outputs
17–32.
In a single frame, there is no redundant power supply available. Dual
power supplies can be installed in the 3RU frame.
