Logic inputs are defined as

1 logic High (+5V)
X State has no effect
The National Instruments DAQ analogue outputs are single ended with a common reference
connection whilst its analogue inputs should be operated in NRSE (Non-referenced single-ended
mode), refer to the relevant National instruments DAQ User manual for further information.
The power supply to the DUT has a dual rail output with a range which is twice the level of the
control voltage input from the NI DAQ system. The control voltage range of 0 to +/-10V will
correspond to a voltage output of 0 to +/-20V from the power supply.
The X, Y & Z Channel drive signals are balanced outputs with a range twice that of the control
voltage input from the NI DAQ system. The control voltage range of 0 to +/-10V will correspond to
a voltage output on the drive signals of 0 to +/-20V.
The power supply monitor voltage returns half the actual measured voltage.
The power supply currents return the current measured across a 1 Ohm (1%) resistor.
Reserved lines may be used for later enhancements by Bartington Instruments.
All Reserved lines must be held at logic High (+5V).
Lines marked No Connection Should be left disconnected.
