USB 6212 and TxD and RxD signals

[Lawaetz]

Hello, 

I am relatively new to LabView.

We have a USB-6212 and I want to use it to read outputs from a digital newtonmeter. 

The newtonmeter has serial port. From the newtonmeter manual I have the following pinout (here I have attached a couple of screenshots, hope they show up correct)

My question is:

How do I handle TxD and RxD signals in Labview? Can it be done with the hardware (computer, NI USB-6212, newtonmeter with serial port)? 

The application does not need to log at high speed - 100 Hz is more than enough

Thanks in advance,

You can save a lot of time and money by purchasing a USB-RS232 adapter like https://www.ni.com/en-us/support/model.usb-232.html

Thanks for the reply.

I see you recommend a new piece of hardware

However, we want to connect some other items simultaneously, where the USB-6212 is well-suited

Is there a way I can use the USB-6212 directly?

Not inherently, because all that you've is just a generic DIO, you've to implement the UART protocol in your application by using bit-bang.

You can still use the 6212 for the other items in your setup and use a USB-RS232 convertor for this TxD and RxD signals.
