Granville-Phillips Vacuum Measurement System Series 307

[Randy-MIT]

Hi,

I’ve been looking for a driver to control my Granville-Phillips Vacuum Measurement System Series 307, but without much luck. The controller I’m using has an IEEE 488 interface. Does any know where I might look?

Thanks,

Randy L.

Hi Randy,

I don't have experience with this particular instrument but you can usually find instrument drivers here. However, I did not see one for the instrument you are using.

Hopefully someone else who is more familiar with this device will know where else to look.

Good luck!

Does anyone have a Granville-Phillips 307 LabVIEW driver for establishing an RS232 communication? This driver exists overseas at companies that utilize the Granville-Phillips 307 and LabVIEW and my computer lacks the language adaptation software.

This VI will poll the instrument for the channel A and B data and write it to a text file.  I think I wrote this for a 307, but I'm not sure.

Please excuse me but

Did you know if you used it for 307 or for other controller. Also can you repost your file since the old one does not have writefile.vi

Thanks,

Tony

Sorry, I don't have that on this computer.  I will fire up my old computer tomorrow to see if it is there.  The file writing VI didn't do anything special.  It just wrote a timestamp and the channel values to a text file.  Anyways, I am sure that I would do the whole thing differently these days, but it did work well.

Hi

maybe this can help you. It is however ment for the 370 or I made a few years ago a mistake.

The INIT initializes the port,
measure and activate are the low level routines. (activating the ion gauge)

read_P is a higher level routine that switches the ion gauge on when the pressure is low enough, not to hurt the ion gauge.

the control helps in selecting the correct device.

happy wiring

Hi,

I am trying to use the program (for 370) but it keeps on giving me error (code: 1073807339). Do you know what changes can I possibly make so that it works?

Hi Tony

This means a timeout. in fact the error is neagtaive: -1073807339
The minus sign is part of the tour.

This could also mean a false wiring scheme, RS232 is a standard called this way because nobody knows anymore what is 2(sending or receiving)
and 3 (receiving or sending) so I ende up saying RS232 means Regularly Soldering 2-->3-->2 and again because the soldering was right but the baudrate was not.
Or something like it.

Do you have a manual with commands from the 307 ?
And do you really have baudrate and handshake ok, and also CTS and DTR effectively connected.
The CTS means do not send yet
The DTR means I am powered on.

and all these details need to be correct or you get a timeout.


You can also look with an oscilloscope if the 307 is talking back at all.

Albert,

Code works great! Thanks for the upload. For those of you still having problems, I have an older model 307 (apparently they updated these after Brooks bought GP) and it was essentially plug and play. Some of you errors might be do to communication problems.
