Device Drivers for Ohaus Defender series balances

[cndrsen]

Are there device drivers for the Ohaus Defender series balances? Specifically one that would support model T51P. I have tried turning off the ID query on the drivers that support other Ohaus models, but this does not seem to work.

Any help would be greatly appreciated!

Good afternoon,

All the 3rd party instrument drivers NI offers can be found at ni.com/idnet.  Since I don't see your scale on it, we do not offer any drivers for it.  You can, however, create your own instrument driver.  NI offers a class on how to create instrument drivers, which uses VISA commands to communicate with the instruments.

Regards,

Lisa

cndrsen, have you had any luck with the T51P? I've tried writing my own driver using Visa, but keep getting crashes and hangups.

Has anyone had any luck with this? I'm looking for a labview driver for the Defender 3000 T31P Model. Or has anyone got a vi that i could modify/use?

Any help would be appriciatted.

Cheers

Pete

Forgot to post - here's the plugin I wrote for a Ohaus T51P connected to a Defender 5000 scale.

Hi Brendan,

I couldn't find a driver online for your specific model balance (T31P Defender 3000). You can request a new 3rd Party Driver from NI at the link below.

I also wanted to get you an article that might be useful in transitioning your Defender 5000 scake read to your Defender 3000 scale. I don't think there should be many changes to get this to work with your 3000 series scale.

Let me know if there are any other issues you're running into!

I found the below VI in the end that worked well. Just had to change the input string to "P\r\n" (being careful of the string input properties as backslash code property is enabled) and then do some post processing to remove unwanted string elements from the output.
