Closing the switcher
To close the switcher when you have finished performing a procedure in this
chapter, do the following:
1. Reinstall any cables you removed. To connect a self-latching cable to a
receptacle, align the holes in the connector with the pins in the
receptacle, and press evenly until the receptacle tabs lock into
place.
2. Place the top cover (and the front cover if a firmware upgrade was
performed) in place and replace all the screws that were removed in Opening
the switcher on page B-2.
Installing and removing video and audio modules
The Matrix 50 Series switchers are field upgradeable. The following procedures
guide you through the process of:
• Upgrading from composite video (one video module) to S-video (two video
modules) or HDTV/component video (three video modules)
• Upgrading from S-video (two video modules) to component video (three
video modules)
• Downgrading from any of the above configurations
• Adding or removing audio capabilities
• Changing to a different switching matrix configuration (from an 8 x 4
configuration to a 12 x 8 configuration, for example)
1. Audio modules are always installed on the bottom of the switcher chassis
(figure B-2). Removing or installing an audio board cannot be
accomplished with video modules in the way. If changing the audio
configuration of your switcher, remove all video modules first.
2. Video planes in the Matrix 50 Series switcher are configured from the top
down; if the switcher is configured for composite video, only the top video
location is used; if configured for S-video, the top two locations are used.
3. When adding video modules, the new module(s) must be of the same
matrix configuration (8 x 4, 8 x 8, 12 x 4, or 12 x 8) as the existing
module(s).
