See my other post on the multimeter itself: True-RMS Digital Multimeter Uni-T UT61E
First, I set up my Raspberry Pi with Arch Linux ARM using my script arch-linux-to-sdcard.sh (which follows the instructions on http://archlinuxarm.org/platforms/armv6/raspberry-pi).
Then I log in via SSH and set up everything on the command line:
The Rohde & Schwarz HMC 8043: A 3 channel power supply 0-32V, max. 3A, 100W.
- Total output power: 100W
- Maximum current per channel: 3A for HMC8043
- Half-19″ form factor, rack mountable
- FuseLink, FuseDelay, EasyArb, EasyRamp
- LXI, LAN, USB (TMC and virtual COM port)
- Data logging directly to flash drive (csv file)
The default ports are:
- Raw TCP:...
- HMP4030: 3 × 0 V to 32 V/0 A to 10 A (384 W)
- HMP4040: 4 × 0 V to 32 V/0 A to 10 A (384 W)
- Low residual ripple due to linear postregulators
- Realtime voltage, current and power values
- High setting and readback resolution:

The ITR 90 transmits the measured values via RS232. The protocol is given in the detailed manual.
I wrote a software to read out the vacuum gauge with you computer:
Mapping of the RS232 port to the DSUB15 connector on ITR90:
|Connector DSUB15||Meaning RS232|
|Pin 13||TxD (Transmit Data)|

The XGS-600 Gauge Controller accepts any of three different kinds of gauge cards which, between them, operate all Agilent vacuum gauges. Choose from
- Convection gauges such as thermocouple or ConvecTorr
- Hot filament ion gauges
- Inverted magnetron (cold cathode or Penning) gauges
Up to six cards can be installed in the XGS-600 Controller, in...

Plug'n'Play on Linux
Plug the Prologix GPIB-USB Controller in on your Ubuntu 11.04 machine (most probably it will work on most older versions too) it directly shows up as a serial port via USB, such as
/dev/ttyUSB0. No additional drivers needed. Here is the output of
dmesg when you plug it...
