Reading the LEDs

Reading the LEDs of the MPX 423 A matrix switcher is the primary means of

controlling your inputs and outputs. The unit uses a series of LED colors and

actions to indicate the status of each group and/or tie.

When in audio-only or video-only mode

•A lit input LED represents a tie.

• The lit I/O LEDs show the signal type (audio or video).

When in A/V mode

• A lit input LED represents a video-only tie.

•A flashing input LED represents an audio tie.

•A flashing audio I/O LED represents audio that follows the video signal.

• An active video LED is always lit.

A flashing output LED represents a muted state.

Determining the current switcher mode

As shown at right, the current switcher

mode is indicated by the front panel input

LEDs of the Computer group.

Using the Switching mode

In order to select or view the single and separate modes of the MPX 423 A, use the

Switching mode. To use this state to check the unit’s current mode status, do the

following:

1. Select an output (1 or 2).

2. Press the Mode button for approximately 3 seconds, until the Single and

Separate LEDs light. The flashing LED indicates the active mode.

Here, you can choose between Single and Separate mode, and view which one is

currently active.

In Switching mode, the only active front panel LEDs are those within the Computer

group (Mode, Single, and Separate indicators) shown above and in figure 3-3. This

signifies that the unit is in “mode indication” (i.e., you cannot view the current

inputs). If a selection is not made during this “mode indication” phase, Switching

mode times out.

To change the mode, continue to hold the Mode button and press the button that

corresponds to the setting you want to change. Figure 3-3 on the following page

shows the front panel buttons and LEDs that are active during Switching mode.

Release the Mode button and the front panel LEDs resume input indication.

Changes to the Single Switcher mode and Separate Switcher mode take effect

when the button is released.
