@ CAEN N1419 Set programmable parameters - see CAEN N1419 manual p.16 (attachment 1) INTERLOCK = CLOSED CONTROL = REMOTE Set front panel switches HV on/off/kill = ON No interlock jumpers @ AIDA server From a command terminal, login to nnrpi1 using ssh, set device permissions, and launch putty. ssh -X nnrpi1 -l npg password: : : : % sudo chmod 777 /dev/ttyUSB2 % putty & From the putty window sequentially select 'USB2', 'load' and 'open' - this will select and load a saved serial session for device /dev/ttyUSB2 and launch a command terminal for the serial session. Enter the command 'caen' followed by return. Note the command is not echoed. The CAEN HV interface should appear. Enter the command 'd' to display/modify parameters. See CAEN N1419 manual pp.27-29 for further commands. See attachment 2. N.B. The above procedure assumes: /dev/ttyUSB0 = USB-controlled ac mains switch (device pl2303) /dev/ttyUSB1 = serial link to FEE64 system console (device FT232RL) /dev/ttyUSB2 = CAEN N1419 (device FT232BM) However, these assignments may vary. You can use the command dmesg to check assignments.

You should then set the device permissions for *each* /dev/ttyUSB[n] and start a putty session for *each* CAEN N1419 module. You can distinguish CAEN N1419 modules by the address (Addr) label shown in the CAEN display.
