holmarc stepper motor control

[BHARATHINDIAN]

hi,
    I have a stepper motor controller  by HOLMARC and they said it is labview compatible. Since they haven't provided any information in their manual about how to interface it with labview can u pls tell me how to interface non NI motor controller?

Hello BHARATHINDIAN,
I am assuming that your device is being connected to your computer through a serial port and since I am unaware of the LabVIEW version you are using do you mind posting with the answer to that in your next post as well. If my first assumption is correct, the simplest way to interface with your device with LabVIEW is to open the Basic Serial Read and Write.vi in the example finder. You can navigate to this by clicking on Help<<Find Examples<<Hardware Input and Output<<Serial<<Basic Serial Read and Write. Once this example is open, make sure to correctly identify the port,data bits, parity, and baud rate that your device will communicate at.
Another option that will allow you to use LabVIEW to work with your device is to look at the following Developer Zone article on creating your own Instrument Driver for the device you are using. Thanks again and have a great day!

Hello BHARATHINDIAN,
I also want to make sure that you have NI-VISA and NI-Serial installed along with LabVIEW which will allow you to communicate with your USB-RS232. After installing these drivers, with your hardware not attached to your computer, and you reattach your device, does it show up in Measurement & Automation Explorer under devices and interfaces. Refer to the attached picture if you have questions on where to look for the device. Once this is setup, you will be able to directly refer to your device in the LabVIEW example mentioned previously, which if configured correctly should allow for communiction. Thanks again and have a great day!
