4. CAENET Interface
Besides the RS232 interface, the V793 can be remotely controlled by a standard PC (with
an A303A board installed) via CAENET interface. For details on the A303 board installation
and operation, please refer to the
Mod. A303A High Speed CAENET PC Controller User’s
Manual.
4.1. The V793 CAENET Controller
An example program (v793caenet.exe) is available from CAEN FTP site
ftp://ftp.caen.it/pub/DocCaen/icarus
to control the V793 via CAENET on Win platform. The
v793caenet.exe program requires the A303A to be installed at I/O space address hex
H280. The full v793caenet.exe source code is available from
ftp://ftp.caen.it/pub/DocCaen/icarus/v793caenet.zip
. For details on the CAENET commands
format please refer to APPENDIX A.
Connect the V793 to the A303A on the PC via a 50 Ohm coaxial cable (the CAENET line
needs to be terminated on the last board) and then run v793caenet.exe. Insert the CAENET
station number according to the thumble switches setting on the module’s front panel and
then press OK; the V793 DACs values, the voltage measured by the ADCs on the
CON_HV1…4, DGND, +5VA, +5VD and –5VA lines, the CAENET station number and the
Enable, Test and DRV lines status will be displayed on the screen as illustrated in Fig. 4.1.
To set any EN_BRD line status, simply click on the relevant box and then press the Set
button; to set the DACs value, click on the relevant box and insert the desired value (hex)
then press the Set button (FFF corresponds to +2.5 V). The DACs values and the EN_BRD
lines status set by the User are stored in memory after module power OFF. The voltage
measured by the ADCs on the CON_HV1…4, DGND, +5VA, +5VD and –5VA are
displayed on the screen.
