 + 
 +==== Telescope ==== 
 + 
 +cacor setup? 
 + 
 + 
 +==== DAS ==== 
 + 
 +  * Make sure the "8 bit" cable is connected between DAS "DigiOut" board and VSIC 
 +  * Set VSIC to mode **** (Huygens) 
 +  * Configure DAS using ''msl_f.pro'' profile. This gives a 4 MHz band, offset from central ATCA IF frequency by -3 MHz. 
 + 
 +==== Recording ===== 
 + 
 +Record the data using the command: 
 + 
 +   vsib_record -m 2 -bits 8 -w 4 -x -o EXPERIMENTNAME -t Xh 
 +    
 +Where "X" is the recording time in hours. There is an alias to allow this to be simplified to: 
 + 
 +   radarrecord -o EXTERIMENTNAME -t Xh 
 + 
 +==== Realtime copying of data ==== 
 + 
 +`vsib_send` will send .lba data files when they are "complete", ie the end of 1 1 minute file in normal setup. 
 + 
 +On the recorder run (for example): 
 + 
 +   vsib_send -online -H cetus -p 11111 
 +    
 +On the receiving machine (cetus in the example above) 
 + 
 +   vsib_recv -p 11111 
 +    
 +The port numbers must match and be allowed through filewall 
 +    
 +==== Realtime spectra ==== 
 + 
 +Create realtime spectra to be loaded onto the interactive webpage: 
 + 
 +   fauto_ipp -n 80000 -bw1 2.25 -bw2 2.65 -t 60s -online -noplot -dump -command "scp %s yarrie:atca.spec" 
 +   fauto_ipp -noplot -n 4000 -t 10s -online -dump -command "scp %s yarrie:atca_full.spec"' 
 + 
 +Create realtime spectra in ".rdr" format and copy to the ATNF ftp area (using `vsib_send`): 
 + 
 +   fauto_ipp -n 4000000 -bw1 2.4 -bw2 2.5 -t 1s -online -dump -radar -noplot -lo 7159 -command "vsib_send -p 50001 -H cetus %s"  
 + 
 +This requires a vsib_recv process running on "cetus", on port 50001: 
 + 
 +   vsib_recv -p 50001
