Definitions; Power/Data/Audio Led And Infrared Sensor - Extron electronics MAV 44 Series User Manual

Definitions

The following terms, which apply to Extron matrix switchers, are used throughout
this manual:
Tie — An input-to-output connection
Set of ties — An input tied to two or more outputs. (An output can never be tied
to more than one input.)
Configuration — Consists of 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 16 global
memory presets can be stored in memory. The input and output buttons are
used to select the desired preset memory location to load or retrieve a preset.
When a preset is retrieved from memory, it becomes the current
configuration. On each model, there are as many presets available from the
front panel as there are input and output buttons:
• MAV 44 models have 8 presets available on the front panel.
• MAV 48 and MAV 84 models have 12 presets available on the front
panel.
• MAV 88 models have 16 presets available on the front panel.
On smaller MAV models, presets that are not available from the front panel
are still available under RS-232 or optional IR 501 control.
Power/audio/data LED and infrared sensor
Infrared remote sensor — This sensor receives infrared (IR) signals from the
1
optional IR 501 small matrix universal remote control. The IR remote control
must be pointed within 30 degrees of this sensor for best results.
Operation of the IR 501 remote control is described in the IR 501 Small Matrix
IR Remote Control User's Guide.
The switcher's IR receiver is disabled by default and must be enabled to use
the IR remote control. See the IR receiver enable SIS command in chapter 4,
"Remote Operation" to enable the IR receiver.
Keep the switcher out of bright light to prevent interference with the IR signals
from the IR 501 remote control.
Power/data/audio LED —
2
• When lit, the Power LED indicates that power is applied to the matrix
switcher.
• When blinking off and on, the Power LED indicates that an IR signal
has been received.
• In Audio Setup mode, the Power LED also serves as an audio meter that
is tied to output 1. The LED blinks frequently when the selected input's
audio level has been adjusted to the –10 dBV internal reference level. (In
Audio Setup mode, the selected input's audio is automatically tied to
output 1.) See "Adjusting input audio gain and attenuation" on
page 3-19 and "Optimizing the Audio (Audio/Video Switchers)" on
page 3-27.
