Setup

• connect DVM:
  • use DB9-male--DB9-female straigh-through serial cable
  • in the HPDVM, set communications to 115200 baud, RTS/CTS flow control, 8bit, no parity
• setup ser2net:
  • setup set2net per ser2net instructions, use this ser2net.conf file:

### HP DVM
3001:raw:600:/dev/ttyS0:115200 -XONXOFF -RTSCTS LOCAL
#3003:raw:600:usb-4-2.3-1.0:115200 -XONXOFF -RTSCTS LOCAL

• • in start_daq.sh, add this before start of mhttpd:

$HOME/packages/ser2net/ser2net -c $HOME/online/ser2net.conf -p 3000

• • start ser2net using above command
  • "telnet localhost 3001", type "*IDN<enter>", the DVM should respond with it's model number identification
• setup fedvm:
  • cd ~/packages; git clone http://ladd00.triumf.ca/~olchansk/git/frontends.git
  • cd frontends/fedvm
  • make
  • ./fedvm.exe
  • it will complain about stuff
• setup ODB:
  • set /eq/dvm/settings/device to "localhost:3001" (address of ser2net)
  • restart fedvm
  • set /eq/dvm/settings/Config to:

[0] func "volt:dc",(@101:120);volt:dc:range:auto on,(@101:120)
[1] SENS:VOLT:DC:NPLC 10,(@101:120)

• • set /eq/dvm/settings/scan to:

[0] rout:scan (@101,102,109,110)

• • set /eq/dvm/settings/ScanPeriod[0] to "60000" (in milliseconds)
  • restart fedvm
  • it should read the voltages on channels 101 and 102 into ODB /eq/dvm/variables
