System Startup
This section describes how to turn on and perform the initial startup of the Model
4000 Switcher. It is designed to assist you in verifying proper operation of the
system, as well as allowing you to reconfigure the preset (default) definitions of
video sources and other system parameters.
System setup is divided into the following areas:
■
Preliminary Steps— Describes the basic requirements for bringing the sys-
tem to the power-on stage. Initial checks, test/monitoring equipment
needs, and verification of proper operation are included.
■
Power Up—Describes powering up the frame and control panel and any
necessary adjustments to be made at initial installation.
■
System Configuration—This section summarizes what system parameters
must be set up using the main soft panel menus to configure the switcher.
■
System Timing—Controls on the Sync Generator allow you to move the
timing of the whole switcher—and the input timing window—relative to
the analog reference.
Preliminary Steps
Before bringing the system on-line, there are several preliminary checks and
preparations to be made.
WARNING
You should observe normal precautions when working around high current,
low voltage power supplies. Always remove rings, wrist watches, etc. before
working inside any of the systems components.
1. Verify that all cabling is clear of cooling fans and that there are no loose tools
or other metal objects near power supply buses or connections.
2. Check that all modules are seated firmly in the frame.
3. Verify that the Control Panel and Signal Processor Frame AC power cables are
properly connected.
