SDI-12 communication with myRIO

[Scott0110000]

I am trying to set up communication between water potential sensors using SDI-12 communication and myRIO 1900. Can I just short the TX and RX pins to connect the data wire to both pins or is there another way of going about connecting the data wire?

I'm not familiar with the SDI-12 communication, but it seems to be some serial communication and it is documented on how to use LabVIEW to communicate with SDI devices.  Here is a link that has a tutorial.

As for you question, I would think that depending on the device, you would either use the Rx or Tx and ground the other and then process the data received, or hook up through a serial connection to the myRIO.
