====== Reprogramming the DBBC ======
Sometimes the DBBC needs reprogramming because channels have been dropped or spectra look strange. To do this, preferable in a gap between scans, follow the following steps:
  - Open a VNC connection to the DBBC. At Hobart, connect to 131.217.63.248:0 <code>Applications --> Auscope Hobar --> VNC -->dbbchb </code>
  - You should see a window named ''DBBC2 Control DDC v104_2.exe''. Close it and then restart it from the desktop. When prompted to reconfigure press "y", it takes about 2 minutes.
  - It is then necessary to make sure the DBBC is synchronised with the station PPS. After some time, in eremotectrl type:<code>dbbc=pps_sync</code> You should then see a row of LEDs on the DBBC flash in sync, once a second.
  - Lastly, the Mark5 time needs synchronising. To do this, open a terminal on pcfshb and type <code>fmset</code> In the interface, type ''S'' followed by ''y'', then press the **ESC** key.
  - In the oprin window on pcfshb, type <code>mk5=dot?</code> and check that you see ''syncerr_eq_0'' and ''FHG_on'' (or ''FHG_off''). If you see something like ''syncerr_gt_3'' then ''fmset'' may need to be run again. 
  - Also check that the maser-GPS and delay through the DBBC are the same (to within a microsec) with the ''maserdelay'' and ''clkoff'' commands which read the Agilent counters.
  - If one or both counters are not responding to these commands, you will see an error message like this <code>ERROR sp   -4 GPIB Device time-out on response c2</code> To fix this, try re-setting the counters. In the ''oprin'' window, type <code>counter</code> and try the ''clkoff'' and ''maserdelay'' commands again.
