Open a VNC session to the DBBC you want to configure from the Applications menu on Ops4:
C:\DBBC_CONF\ are several configuration files for different experiment types. The configurations used for IVS are:
dbbc_config_file_geo.txtfor R1 and R4 geodesy
dbbc_config_file_geo_16.txtfor AUSTRAL sessions
dbbc_config_file_APSG_CRF.txtfor APSG, CRDS and CRF geodesy
dbbc_config_file_T2_OHIG.txtfor T2 and OHIG
The default configuration is kept in
dbbc_config_file.txt and this will be loaded when the server software is started.
(If you want to change the default, Copy (i.e. Do NOT rename) the appropriate file to
Check to see if a program called
DBBC Control net.exe is running. If not, start it and say “y” when asked if you want to use the default config, otherwise “n”.
DBBC Control net.exe which can be found on the Desktop. If you didn't accept the default config, load the file you want now with the LOAD command. e.g.:
Then configure the DBBC with a
Configurations will take about 2 minutes.
When the configuration is complete, synchronise the DBBC to the station pps with the following command:
Enter Command: pps_sync
You now need to set up the IF system. The commands to do this depend on the IVS observation and the station.
For R1, R4, CRF, CRDS, AUSTRAL and RDV experiments on they should be:
dbbcifa=1,agc,1 dbbcifb=4,agc,4 dbbcifc=2,agc,2 dbbcifd=2,agc,2 dbbcform=geo
For APSG, OHIG and T2 experiments, for all stations they should be:
dbbcifa=1,agc,1 dbbcifb=4,agc,1 dbbcifc=2,agc,2 dbbcifd=2,agc,2 dbbcform=geo
Recommended DBBC power levels can be found here. Current target values for the total power readings is 56000. this can be checked by the command: ifa, ifb, ifc or ifd. If the levels are too high or low, then adjust the attenuation on the IF box. Note that the levels on IF C (e-remote control command: ifc) are a bit low. Don't worry about it.
