The following information is for the EMANT300, EMANT380
The Screw Terminals Application Adaptor connects the pin out of the DB25 connector of the EMANT300 Low Cost USB Data Acquisition Module or the EMANT380 Bluetooth Data Acquisition Module to screw terminals.
It is used for rapid prototyping of PC or Smartphone Based Data Acquisition Solutions. Together with the EMANT300 Low Cost USB Data Acquisition Module or the EMANT380 Bluetooth Data Acquisition Module, they allow for quick connection to real world sensors and signals without the need for soldering.
It has a 2-layer prototype board with plated through 26 x 25 grid holes for user defined signal conditioning.

Note: If you are making any analog input measurements, pin 4 REFIN- must be connected to pin 2 AGND. When you do this the internal reference is correctly set up.
Pin 2 is connected to pin 4 in other application adaptors that measure analog inputs, like the light application adaptor and strain application adaptor. Not all applications require this connection eg when using an external reference or making ratiometric measurements. If you are using the internal reference (default setting), this must be done.
