SensorDAQ (SDAQ) is a lab interface for use with LabVIEW and engineering education. The analog output on SensorDAQ is on the screw terminal connections. It has a 0 to 5 volt output. There are two ways to make the connection from SensorDAQ to the Power Amplifier (PAMP):

Make the connection via the BTA connector
Use a cable with a BTA connector on one end and bare wire on the other, such as the Analog BTA Cable (CB-BTA). Pin 1 on the BTA plug (the farthest from the tab) should be wired to the #9 screw terminal (analog out) on the SensorDAQ. Pin 2 on the BTA plug base of the connector should be wired to the #10 screw terminal (ground). For a complete BTA pinout diagram, see here: https://www.vernier.com/til/5457 Using this connection, the Power Amplifier will increase the voltage by a factor of 2.

The advantage of this method of connection is better resolution on the analog output, since you are using the full range of the SensorDAQ analog output. A sample VI showing how to control the SensorDAQ analog output is included in the SensorDAQ Examples folder.

Make the connection via the 3.5 mm input using a mono audio connector
The tip of the connector should be wired to the #9 screw terminal (analog out) on the SensorDAQ. The base of the connector should be wired to the #10 screw terminal (ground). Using this connection, the Power Amplifier will increase the voltage by a factor of 10. This means that you should only use SensorDAQ analog output settings up to one volt.

This method allows you to simultaneously use the BTA connector on the Power Amplifier to connect to the SensorDAQ. You can then read the current sensor built into the Power Amplifier with SensorDAQ.
