arc monochromator driver

[josan]

hi,

can anyone help me how to control arc spectrapro model275 using labview.

i didnt have instrument cd.so do not have that spectrapro_sdk driver.do anyone have this driver

I tried to find your instrument on our instrument driver site (www.ni.com/idnet), but it is not listed.

How is your PC communicating to your instrument?  If it is through GPIB or serial, LabVIEW comes with example programs that write and read via GPIB and Serial communication.

In LabVIEW, you can click on Help>>Find Examples to open the NI Example Finder. Here, you can go to the Hardware Input and Output folder and browse for Serial or GPIB examples (depending how you are communicating with your instrument). These examples show you how to use Write and Read functions to communicate with your Serial/GPIB device.

I did a program for an ARC Triax 180 monochromator a few years back.  The monochromator used serial communication and was very easy to program.  I didn't need, nor write, any kind of driver program.  I think that all of the information that I needed was available at the ARC website.

hi

thanks for replying. communication with instrument is using  serial port.

ya i have use some of the serial  write and read  VI. i send a string and was able to retrieve it. but i am confused how to take spectrum ,set wavelength ,grating turret etc using  that basic serial read write Vi.

i am able to communicate ,but not able to take reading measurement etc

do anybody has vi made for it.

thanks

hi

actually i check arc site but i didnt find any software or driver to control monochromator.

suprisesingly i even didnt see my model there.

thanks

Do you have any of the documentation that came with the monochromator?  If not, call and see if they will send you a copy of the documentation.  Setting wavelength, etc. was easy, but I used my own detector so that this was a separate process.  I could probably send some of my code, but it won't do everything that you need.  If you can get the documentation I could post some of my code to show how I implemented the process.

hi john

actually i call them up few days ago.they send some codes,which i already has.

this are like <goto> , <nm> ,<turret> etc string.

but i didnt now what to do with command using labview.

i use some commands in labview basic serial read and write and was able to retrieve it .

it mean communication is there.

my problem i s how to set various parameter like wavelength ,grating etc. and take spectrum.

can u plz assist

i wil appreciate ur effort

thanks

josan,

I have attached the subvis that I used to set the grating and the wavelength, along with their associated subvis.  Hopefully this will be helpful to you.  Basically you just send serial strings using the command set that ARC gave you.
