how to communicate with Kubler encoder

sisco79901 · ‎10-30-2008

Hi, I need to communicate with a Kubler RS485 encoder that use Esc comands (<ESC>00P<CR><LF> for position). I have been using VISA VI's with other instruments for some time with no problems. I have computers with windows Vista and XP and it seems Esc commands need real time that Win XP/Vista does not support. Any help will be appreciated. Thank's

Dear sisco79901,

What encoder model you are using? This is the closest I could find:

http://www.clrwtr.com/PDF/Kubler/Kubler-9081-Absolute-Encoders.pdf

And for this and other models I've looked up, you set up the hardware configuration by setting certain lines either low or high before powering the encoder.

Can you provide a link to the spec sheet or manual for your specific encoder? I also have not found any reference to these Esc commands in any of the Kubler literature I've looked at thus far.

If you are sending commands to specific control lines in terms of setting that voltage low or high, you can use any device that will output the appropriate voltage (MIO DAQ card for instance) and the DAQmx driver in LabVIEW.

If you have to send these commands over RS-485, then you can still use the NI-VISA driver, as it does support RS-485 serial communication.

How Do I Enter the Escape (ESC) Character in LabVIEW 6.1?
