Fluke 8845A Ethernet communication with labview 8.5

[Ziv G]

I try to control a 8845A fluke DMM with Labview 8.5 through ethernet communication,
and I have already downloaded the driver of 8845A fluke from the website,
 but by running the initialize.vi , I get an error, the error is " -1073807339 VISA Read in Fluke 884X Series.lvlib:Initialize.vi"  
 
Could anyone give me some help. Thanks a lot.

Ziv,

You need to verify that the driver you downloaded supports ethernet.  It sounds like you are trying to use a driver that supports GPIB or serial.

Hello,

Thank you very much for your very quick answer. I saw that the driver as is appear in the website is supports  GPIB or Serial , as you said.

Did you know if there is a  driver that supports ethernet somewhere?

this is the link for what I downloaded :

The driver is written with VISA and it should work with no modification. Did you first use MAX to locate the instrument? If you did, the VISA Resource Control should list it and you should be able to select it. To locate it in MAX, right click on Devices and Interfaces and select Create New>VISA TCP/IP Resource. You should first determine from Fluke whether the instrument is VXI-11 complian or not.

Thank you.

 I used MAX to locate the instrument. I see it in the VISA Resource list in the VI font panel and I selected it. But I don't know wheater the instrument is VXI-11 complain or not, and I didn't see any list of VXI-11 instrument so I created it from "Manual Entry of Raw Socket".

 Did it important to know if it's VXI-11 complain or not??

If it's  VXI-11 complain  about what it affect me as a user?

Thanks

Hello,

The driver does not support Ethernet interface because it is not VXI-11 complaint.  We verified this when developing and testing the driver and confirmed this with Fluke.

I have modified this driver so that it works. I am not going to post it because it is straight forward to fix.

The problem is with the commands that the multimeter is expecting an "\n" at the end of read and writes.

So quite simply set Surpess End Enable to false - this fixes the reads

and replace VISA Write in each VI with a find\replace with the VI found here

Hope this saves a few days of someone elses life...
