3.1 Typical Connections for the SRV02 – FLEXGAGE Experiment
The following table describes the typical setup using the complete Quanser solution. It is
assumed that the FLEXGAGE is being used along with an SRV02, UPM and Q8 DAQ
board.

6-pin mini
DIN to 6-pin

This cable results in delivering a ±12V bias
to the potentiometer and measuring the
potentiometer signal voltage on S2 of the
UPM.

Stereo DIN.
The terminal board should supply the
encoder with the +5V and ground. The load
shaft position signal will then be measure on
Encoder channel 0.

6-pin DIN to
4-pin DIN.
This connects the output of the amplifier to
the motor. You can use a variety of cables
resulting in a different gain from input to
output. The cables available are Gain=1,
Gain=3, Gain=5.
Analog Signals
(To A/D)
Analog input
channels 0-3
on the DAQ.
5-pin DIN to
4x RCA.
From the UPM, connect all the analog
sensor signals to the terminal board such
that S1 is measured on analog input 0. S2 -
AI # 1, S3 - AI # 2, S4 - AI # 3.
Analog output
channel 0 on the
DAQ.
UPM input
(From D/A)
RCA to 5-pin
DIN.
This is the command output from the DAQ
that will be amplified and drive the motor.

3.2 Calibrating the Strain Gage
The FLEXGAGE uses a strain gage mounted at the base of the link to measure the
deflection of the tip of the link. Before the module is shipped, the unit would have been
fully calibrated to the correct specifications. The following section will describe the
calibration routine in order to ensure the unit maintains its correct calibration and thus
remains operating correctly.
This section describes functional tests to determine if your FLEXGAGE sensors are
operating normally. It does not cover any performance tests. All these tests require an
understanding of Simulink (or Labview), WinCon (or equivalent), and Q8 (or equivalent
data acquisition board you are using). You should be able to “build” a controller that can
measure and apply desired signals.
