TB7300 Installation and Operation Manual Connecting to the Base Station 35© Tait Limited November 20174.4.4 Working with Configuration FilesAt any time, you can save the current configuration settings as a file(Tools > Files > Configuration > Backup configuration). This is stored inthe base station, but we recommend that you download it and store it onyour computer as an off-site backup. The base station identity and networkidentity are not saved as part of the configuration file.You may want to develop a master configuration and upload it to all basestations in the network. The master configuration can contain all thedifferent channel configurations and can be common to all base stations.The base station identity selects the default channel.Base stations are delivered with a default configuration which providesa safe set of values. We recommend that you download it and store it onyour computer as a backup before changing and saving any configura-tion settings.You can also generate a report containing all the base station’sconfiguration settings (Tools > Files > Configuration > Configurationreport), which can be saved as a text file. We recommend that you do thiswhen the base station is commissioned. This report can be useful later ifthere is a problem with the base station. Comparing the original report withthe later one may highlight changes in configuration that are causing aproblem.4.4.5 Single or channel group base stationsBase stations can operate singly, or as part of a simulcast or voted channelgroup. Channel group operation is enabled in the channel group profile:(Configure > Channel Group > [name]), and the channel group that is in-use is selected in the channel table (Configure > Base Station > Channels> [name]). To disable channel group operation, deselect the ‘enable’ check-box in the profile referenced by the channel. For more details, see the DMRSimulcast and Voted Channel system manual.4.4.6 Marshaling or transmit delayAs an IP connected base station, transmitters must buffer the signal to betransmitted so that variations in delay in the IP network do not cause thetransmitter to underrun.Non-simulcast channels use a configurable transmit delay: After the signalto be transmitted arrives at the transmitter, the transmitter buffers thatsignal for the nominated delay before beginning transmission. The amountof transmit delay required varies with the QoS (specifically, jitter) of the IPtransmission network.
