You can also remove multiple mountpoints by highlighting them using +Shift and +Ctrl.</p><p>BNC automatically allocates one of its internal decoders to a stream based on the stream's 'format' and 'format-details' as given in the sourcetable. However, there might be cases where you need to override the automatic selection due to incorrect sourcetable for example. BNC allows users to manually select the required decoder by editing the decoder string. Double click on the 'decoder' field, enter your preferred decoder and then hit Enter. The accepted decoder strings are 'RTCM_2.x', 'RTCM_3.x', and 'RTIGS'.</p><p>In case you need to log the raw data as is, BNC allows users to by-pass its decoders and and directly save the input in daily log files. To do this specify the decoder string as 'ZERO'.</p><p>BNC can also retrieve streams from virtual reference stations (VRS). To initiate these streams, an approximate rover position needs to be sent in NMEA GGA message to the NTRIP broadcaster. In return, a user-specific data stream is generated, typically by a Network-RTK software. This stream is customized to the exact latitude and longitude as shown in the 'lat' and 'long' columns under 'Mountpoints'. These VRS streams are indicated by a 'yes' in the 'nmea' column under 'Mountpoints' as well as in the sourcetable. The default 'lat' and 'long' values are taken from the sourcetable. However, in most cases you would probably want to change this according to your requirement. Double click on 'lat' and 'long' fields, enter the values you wish to send and then hit Enter. The format is in positive north latitude degrees (e.g. for northern hemisphere: 52.436, for southern hemisphere: -24.567) and eastern longitude degrees (e.g.: 358.872 or -1.128). Only mountpoints with a 'yes' in its 'nmea' column can be edited. The position should preferably be a point within the coverage of the network.</p>"));
