Control CS-200 Konica Minolta chromameter using USB and labview

[DisplayMan]

Hi,

Does any body have any ideas about controling a Konica Minolta CS-200 chromameter using Labview. The Chromameter has an USB interface to the computer that is controlled by its own software. I dont think there is a command language available for this or any such thing. But is there a brute force way of reading measurements from CS-200.

Thank you, Jignesh

at the back of the user's manual there is this URL

for controlling the camera with an independent program

http://konicaminolta.com/products/instruments/download/index.html

download the specifications for the USB driver there

it is probably a DLL that you will need to call from LabVIEW

Thanks for the tip. The dll and instructions look comprehensive. I will have to get smart about calling external instruments from Labview.

Here is an option that might help you reverse engineer the code.

I developed a LabVIEW application a few years ago that use the Minolta CA210 color analyzers.  I used the ActiveX controls in LabVIEW to interface to the unit via USB (RS232 as well).  The unit came with software that you had to install on the target computer (it put the DLLs used to control the unit in the windows system folder and added registry entries).  There was a SDK manual that showed all of the methods and properties in the DLLs; once I figured out how to make calls via ActiveX, I was able to control the unit.

Hopefully the CS-200 can be controlled similarly.  I've attached a subVI used to initialize a CA210; hope this helps!

DisplayMan did you ever complete the labview driver for the CS-200?

Hello,

Does anyone have labview program to control minolta CS-200?

Thanks

Does anyone have labview program to control minolta CA-200 or CA-310?

I did a smal VI to do a basic color measurement with the CA-310 which uses the same driver than the CA-200.
