Typical Applications of the Maintenance Window

In the following section, the typical applications of the Maintenance Window are shortly described.

First, read out the version of the firmware currently loaded. Compare it with the current firmware version recommended by DHD. If you have to update the firmware, proceed as described in the Update page.

First, read out the version of the kernel currently loaded. Compare it with the current kernel version recommended by DHD. If you have to update the kernel, proceed as described in the Update page.

Mixer snapshots save the overall condition of a mixing device. Using the Maintenance Window, you can save the Snapshot 0 that can be loaded to the console by the user. Snapshot 0 is the default setup that is loaded after a system reset. This setup can only be saved in the Maintenance Window. From the console it can be loaded but not saved. (See Device/Mixer 1 to 4)

If you change a core in a system, you might have to update the firmware of the core (see Update). The same applies for the kernel of the core (see Update). Further on, you may have to request new license codes from DHD after exchanging the core (see Enter License).

When exchanging other modules, these update processes are not necessary, because they get the software from the core device automatically.

If it makes sense, you can also replace a newer firmware version by an older one. This may be helpful if you want to insert a new core in a system with older firmware, whereas the core has been shipped with new firmware. If in doubt, ask your DHD vendor or the DHD support prior to any downdates!

Check the current license information for the device. To do this, in the main menu click Firmware and in the next view click License Information. (See Main Window/License Information)

You need a firmware license code for operating the system and optionally software license codes for PC software like Remote Control or for feature upgrades, for example the Enhanced DSP Processing. If you want to enter a new license code, use the command Enter License. (See Enter License)
