3.11. Front panel controls and LED indicators
The following elements are available on the PXN88 front panel:
MONITOR output (1) (marked with a headphones symbol): it produces the same monitoring signal already
•
available via the rear panel screw terminal block, but here on a ¼" TRS jack and with a rotary volume
control (2 ) for listening through headphones. It is especially useful for listening to input or output signals
without disturbing the normal operat ion. In 16x16 mode both PXN units receive the same signal.
The monitored signal is selected with MAJORCOM-Net Manager control software. Please refer to the
MAJORCOM-Net Manager software manual for more information.
Input LED indicators (3): indicate the presence of audio signal at the unit's input, and its intensity level
•
(green, amber and red indicate in this order the increased intensity level)
Output LED indicators (4): indicate the presence of audio signal at the unit's output, and its intensity level
•
(green, amber and red indicate in this order the increased intensity level)
Status LED indicators (STATUS):

1. If the device is configured as 8x8 MASTER, the LED is permanently off.
2. If the device is configured as 16x16 MASTER:
3. If the device is configured as SLAVE:
o
POWER: (7) illuminates when the unit is in operation. It flashes if there is an error in the unit or if
firmware is not correct. It also flashes when you update firmware
4. CLEANING
The front panel should not be cleaned with dissolvent or abrasive substances because silk-printing could
be damaged. To clean it, use a soft cloth slightly wet with water and neutral liquid soap; dry it with a clean cloth. Be
careful that water never gets into the unit through the holes of the front panel.

If everything is correct (SLAVE is connected and there is no communication error),
•
the LED quickly and continuously toggles between green (50ms) and unlit (50ms)
If there is a communication error with the SLAVE, the LED quickly toggles between
•
green (50ms) and red (200ms)
If no SLAVE is connected (or if connected equipment is another MASTER), the LED
•
slowly toggles between green (800ms) and red (200ms)
•
If everything is correct (MASTER is connected and there is no communication
error), the LED quickly and continuously toggles between orange (50ms) and unlit
(50ms)
If there is a communication error with the MASTER, the LED quickly toggles
•
between orange (50ms) and red (200ms)
If no MASTER is connected (or if connected equipment is another SLAVE), the LED
•
slowly toggles between orange (800ms) and red (200ms)
