30 10 Saving the configuration The configuration of a DIS-2 module can be exported as a file and thus backed up. In addition to re-establishing an individual module, the configuration can also be transferred to several modules simultaneously Saving the configuration file To transfer and save the configuration save on the configuration PC, click on Config File > Save. You can decide which configuration groups should be included in the backup In the Config File Management dialog. Fig IMPORTANT If you wish to transfer the configuration at a later date to several devices, you must not save the Network settings configuration group. IMPORTANT If you wish to transfer Track settings, Encoder settings and Video standard to a module which originally had different settings in these areas, the module s images or tracks must be deleted. Click on OK after the selection has been made. Follow the instructions in the download dialogs and save the configuration file. The configuration file is a plain text file. The file name contains the IP address of the relevant module. 30

31 10.2 Sending the configuration file The configuration file saved on the configuration PC can be sent to an individual module. This allows the configuration to be restored on the module that is currently connected. In addition the configuration file can also be sent to several modules at the same time. This is a very effective method of configuring several modules identically in terms of certain configuration groups Individual module To restore the configuration of an individual module, first establish a connection to this module. Open the Config File Management dialog using menu points Config File > Send. Click on Search (Durchsuchen). Select the relevant configuration file on your configuration PC. Click OK. Fig At the end of the transfer the system will display a list of transferred (or skipped) configuration groups. Fig Several modules The prerequisite for this method is that all the relevant devices are integrated in a LAN (with suitable cabling and a separate IP address for each device). In addition the password must be identical for all the devices. Before the configuration file is sent, it must be saved as described above. However, the Network settings configuration group must not be included in the file that you save. If these settings were included, the same IP address would be sent to all the modules. Since, however, every IP address in the LAN must be unique, this would cause massive problems in the LAN. 31

32 IMPORTANT Ensure that the Network settings configuration group is not sent to the modules. To send the configuration file, first establish a connection to one of the receiving modules. Log on and open the Config File Management dialog using menu points Config File > Send. Click on Search (Durchsuchen). Select the relevant configuration file on your configuration PC. Check the Broadcast checkbox. Enter the first and last IP address of the relevant module group. The configuration will be sent to all the IP addresses between Start IP and Last IP. Enter the administrator password in the Password field and click on OK. IMPORTANT The password must be identical for all the modules. This is the case with the default setting (password = 3). Fig After confirming by clicking on OK the transfer will be started. When it has finished, the system will display a list of transferred (or skipped) configuration groups. 32

33 11 Info and log 11.1 Information dialog General information about the module will be displayed in an information dialog. Open the DIS-2/M DecoderPro dialog via About. Fig The following will be displayed: Type of module Version number of the device software Version number of the decoder Version number of the Linux kernel Serial number Information about the Uptime will be displayed in the bottom section MAC adress The MAC address of the network interface is displayed in the Network settings dialog. Open the Network settings dialog via Common settings > Network. Fig Event log Current errors are displayed as a list but they will not be saved.
