GPIB VISA test panel: problems viRead

[borjabm]

Hello everyone!
Let me a very short introduction about myself, I'm a Industrial Engineering student from Spain and I'm doing the master thesis in "Universität der Bundeswehr München", and I'm quite rookie in this field.

I'm writing here because I'm trying to connect the controller of an insrtument "Micromanipulator, Model 6600 CONTROLLER" (I guess none of you have heard about it ever) to the labview by GPIB but I'm not able to get a good response from the instrument.

So, in order to check the conexion between both, I used "NI Measurement and Automation" software, and there I see the conection with the instrument is established, and the device status said "This device is working properly", then I go to the "VISA Test Panel" and if I write anything, standar commands or random letters, I can see in the return status "Operation completed succesfully", but when I go to viRead I always get the same message in the buffer, that in ASCII code is a string of dots ".............." occupying all the space that I gave it previously in the Count.

I would be very thankful if any of you can tell me some way to try to make it work. Thanks in advance.

What does the programming manual for that instrument say about its GPIB communcation capabilities?

The point is that it is an old equipment, so I have some manuals about other newer instrument (from 2001) and I don't know exactly what I can take from it. I sent some emails to get the manuals of my version, but while, I'm trying with common commands like *IDN?/n (that is the default command in the buffer of the viWrite) and with commands from that manual like prbpos.

Additional information:

    Angilent 82357B USB / GPIB

    Windows xp

    NI MAX V 5.3.3 f2

    Original software to the equipment (according with this manual): pcBridge 3 (2001) & National Instruments AT-GPIB/TNT

Attached the manual of a newer version:

The point is unless you know what the particular instrument will respond to, you are just wasting your time.
