Each TetraScience Link has up to 4 data streams (A-D). If you have one sensor, you'll only see stream A, if you have two sensors, you'll see A and B, and so on. A possible problem is that one or more feeds will stop outputting data. Below are steps you should take before contacting support.


What does it mean if my device is 'not streaming'?
If the device is online, as indicated by the green icon, but no data shows on the graph or real-time readout, the device is not streaming.


  1. Check if your sensor(s) are plugged into the USB port. If not, plug them back in.
  2. Reboot the link by disconnecting the power cord, waiting 10 seconds, and then plugging it back in. 
  3. Make sure the sensors are plugged into the correct USB ports (A, B, C or D). You can find the USB port specified on the lower left corner of the device panel. In the panel above (Link tsdev-30-A), the instrument listed is the sensor, and it goes in port A. 
  4. Try plugging in a sensor from a working device, and see if it starts streaming. If this works, let us know.
