====== Device Menu ======
===== Reconnect =====
The ''Reconnect'' command interrupts the TCP/IP connection between the Maintenance PC and the selected device and opens it again. This way, the current settings of the device are read out automatically.
**Tip**\\ For certain functions, transferring the commands can take quite a while, longer than the Refresh process of the Maintenance Window. In this case, the old values are shown although the new one are available to the hardware already. Use the ''Reconnect'' function to check the settings if in doubt.
===== Network Config =====
With this command, you open the ''Network Config'' window of the Maintenance software. In this window you can change the IP settings of the selected device.
After selecting a system by right-clicking on it in the device list in the Maintenance Window, a contextual menu opens that allows access to the IP settings using the command ''Network Config''.
[{{ tb5:mtn5-2.png?133x66 |//Contextual menu after right-clicking on a device.//}}]
There are two ways to change the IP configuration of a DHD system:
[[#requested_device_is_available_in_the_list_a|(a) The requested device is available in the list on the left of the Maintenance Window.]]
[[#requested_device_is_not_available_in_the_list_b|(b) The requested device is NOT available in the list on the left of the Maintenance Window.]]
==== Requested device is available in the List (a) ====
- Right-click on the device name in the list.
- In the contextual menu, select ''Network Config''
- The ''Network Config'' window opens and shows the IP configuration of the device.
[{{ :tb8:maintenance:network-config.png?nolink |//The "Network Config" window shows the current IP configuration of the connected device.//}}]
In the ''Network Config'' window, you can change the current IP configuration of a certain device.
=== Serial No ===
The device the network settings of which are shown, is always represented by its ''Serial No''. This serial number is unambiguous and valid for only one controller. The field is used to read out settings of devices that are located in a different network segment. Find more details on this in the following section "[[#requested_device_is_not_available_in_the_list_b|Requested device is NOT available in the list (b)]]".
=== Hardware Name ===
Every Series 52 system can be assigned a ''Hardware Name'' for better identification of the system. This name helps to identify the device in the network. You can choose any name, it can be up to 30 digits long but may not contain spaces. Special characters that are not allowed, can not be entered. In the Maintenance Window only the first 10 digits of the hardware name are shown.
=== Automatically via DHCP ===
If a DHCP server is located in the network that manages the IP configuration of the selected device, select the option ''Automatically via DHCP''.
=== Fixed - Fixed IP setting ===
If you have no access to a DHCP server or want to adjust the IP configuration manually, first select ''Fixed'' and then enter the appropriate values (''IP-address, Subnet Mask, Gateway, Broadcast'') into the appropriate boxes.
**Tip**\\ As factory default DHD devices will be delivered with IP basic settings based on their MAC address. See [[network:ip#ip_basic_settings|IP basic settings]] for more information.
**Important**\\ In case of question concerning the parameter settings, ask your IT department or your system administrator.
=== Time Server ===
Series 52 systems have an internal system time that can be synchronised using a NTP Time Server. To do this, enter the IP address of your NTP Time Server in the ''Time Server'' box.
Depending on your chosen time server you may need to enter some further settings. Click ''Setup time zone and DST'' to be able to enter a general time zone offset and if necessary the settings for the daylight saving time.
**Tip**\\ A standard Windows PC can be used as a NTP time server, see [[:installation:windows_ntp_time_server|Configure Windows as a NTP time server]]
With 52/XC2/XD2/XS2 cores you also can define two additional Time Servers. If the primary time server is not reachable, the core will use ''Additional Time Server 1''. If ''Additional Time Server 1'' is not reachable, the core will use ''Additional Time Server 2''.
==== Requested device is NOT available in the List (b) ====
You need to add the device manually to your list by using the DHDCS - see [[dhdcs:logging_menu#add_device|Add device]].
After adding the device manually to the DHDCS it might be possible, that the ''Network Config'' window opens with all boxes empty. Click ''Retrieve Current''.
[{{ :tb8:maintenance:network-config2.png?nolink |//Entering the serial number of the desired device.//}}]
This way the device will transfer the current IP settings. These are then shown in the ''Network Config'' window and can be changed there.
Changing the data is carried out exactly as described in [[#requested_device_is_available_in_the_list_a|Requested device is available in the List (a)]]. Changed data are finally transferred to the device by clicking ''Send''.
Nevertheless, if the device is not reacting, communication could be blocked by certain IP settings. In this case it is recommended to adjust the IP settings of the PC to the ones of the device. To do this, temporarily change the IP address of the PC to the one valid for the device. (see [[network:ip|IP basic PC settings]])
==== There is no communication possible with the device ====
If, despite all efforts, the device is not reacting although there is a physical connection to your network, the communication might be blocked due to the current security settings in the network. In this case, check which measures for a higher network security may be dropped (e.g., firewalls, router, managed switches, …).
For solving the connection problems, contact the responsible IT department and check which of the measures described in the network specification have to be done to establish a communication between PC and DHD system.
===== Enter License =====
**See [[licensing:start|Licensing Pages]] for more Information.**
Using this command, you can enter the license codes. There are license codes for the firmware, for software operation snd for feature upgrades, like the ''Enhanced DSP Processing'' license.
**Note**\\ An invalid firmware license code allows unrestricted operation of a device for 600 operating hours, this corresponds to 25 days non-stop operation. After that, the message ''License invalid'' is shown in the module display and TFT displays. Apart from this message, the mixer operation is still unrestricted (except the enhanced DSP functions). After 800 hours of operation without a valid firmware license, the system is interrupted by a random reset approx. once per hour.
Generally, only one license code is necessary for operating one DHD system. Each system has its own license code based on the serial number of the device. You find the serial number under ''Serial Number Device'' in the firmware section after selecting a device.
**Important**\\ You can also get the license for a Communication Controller module. When exchanging this module, you might need a new firmware license code that you can request from DHD.
In most cases, DHD products are delivered with a temporary license code (''valid until''…). As soon as the system has become the property of the customer, DHD sends the permanent license code by e-mail. When you have received the license code, copy it by pressing ''Ctrl+C''. Then select the desired device in the device list and select ''Enter License''. Then, insert the code into the box by pressing ''Ctrl+V'' and confirm by clicking ''OK''. The code is transferred to the device.
Check whether the license code was accepted. To do this, in the main menu, click ''License Information''. If you read ''Firmware License: unlimited valid'' or for temporary licenses ''valid until'' with a new date, the transfer was successful.
**An invalid license code will be ignored!**
===== System Status =====
==== Save To File ====
In the ''Device'' menu, select ''System Status - Save to File'', to save the currently read out status of the device. A file named ''System_Status____
