All settings and parameters will be reset to factory settings

and have to be readjusted to the desired values.

You have two options to reset the P56x to factory default: via web interface or front
panel keyboard.

6.1. Via front panel keyboard

To reset the P56x to factory settings perform the following steps:
s
1. Switch off the unit.
2. Press and hold the “ENTER” button on the keyboard.
3. Switch on the unit with the “ENTER” button pressed.
4. Wait a few seconds before releasing the “ENTER” button.
The P56x now shows factory settings and parameters. The IP address of the CTRL
interface is reset to the default value of 192.168.93.152. For configuration see
section 32 .

6.2. Via web interface

Refer to section 3.5.3 Hard Reboot with Defaults
Defaults.
 44

7. Error handling
In case of an error, there are three possible states:
a) The LED STATUS 1 is permanently off.
b) The LED ERROR is permanently on.
c) The LED STATUS 1 is permanently off and the LED ERROR is permanently on.
The first measure could be a re-start of the unit by either switching the AC power off
and ( after a few seconds ) on again, or by triggering a re-start through the
web-interface, or the front panel keyboard ( refer to section 6.1 Via front panel
keyboard). If the error persists, the configuration should be checked for
unreasonable parameters, like the ASI-transport stream bit rate being too low or
much too high, or an unsupported MPEG2/4-encoding bit rate.
