Extron Electronics MTPX Plus Series User Guide - Manual (Page 36)

Definitions
The following Extron matrix switcher terms are used throughout this manual:
Tie — An input-to-output connection
Set of ties — An input tied to two or more outputs.
NOTE: An output can never be tied to more than one input.
Configuration — One or more ties or one or more sets of ties
Current configuration — The configuration that is currently active in the switcher (also
called configuration 0)
Global memory preset — A configuration that has been stored. Up to 32 global memory
presets can be stored in memory. Preset locations are assigned to the input buttons and
(where necessary) output buttons. When a preset is retrieved from memory, it becomes the
current configuration.
All models have 32 presets. On the MTPX 128 Plus, which has fewer than 32 input and
output buttons, preset numbers that are too high to be available from the front panel are
still accessible under remote or Ethernet control.
Room — A subset of outputs that are logically related to each other, as determined by the
operator. The switchers support up to 10 rooms, each of which can consist of from 1 to 16
outputs.
Room memory preset — A configuration consisting of outputs in a single room that
has been stored. When a room preset is retrieved from memory, it becomes the current
configuration.
Power
Apply power by connecting the power cord between the switcher and an AC source. The
switcher performs a self-test that flashes the front panel button indicators red, green, and
amber and then turns them off. An error-free power-up self-test sequence leaves all input,
output, and control buttons either unlit or showing background illumination and the Video
button and the Audio button lit.
The current configuration and all presets are saved in non-volatile memory. When power is
applied, the most recent configuration is retrieved. The previous presets remain intact.
If an error occurs during the self-test, the switcher locks up and does not operate. If your
switcher locks up on power-up, call the Extron S3 Sales and Technical Support Hotline. See
the
end of this guide for the phone number in your region of the world.
Front Panel Security Lockouts
In the procedural descriptions that follow, it is assumed that the switcher is in Lock mode 0
(fully unlocked). The following two Lock modes are also available:
• Lock mode 1 — All changes are locked from the front panel (except for setting Lock
mode 2). Some functions can be viewed.
• Lock mode 2 — Advanced features are locked and can be viewed only. Basic functions
are unlocked.
NOTE: The switcher is shipped from the factory in Lock mode 2. See “ Setting the
Front Panel Locks (Executive Modes) ” on page 59 for a detailed list of basic
and advanced functions and the procedure to set the various front panel locks.
