3.4.2 Back
The single connector at the back side of the µCROS SL is the POWER/CAN/IO Connector.
This connector bundles all the measurement signals and the power supply which usually
are part of the test rig. This feature facilitates fast connect and disconnect of the µCROS
SL from the device under test. The ordering code and the pinout of the connector are
described in section 7.8.3 on page 30.

5 Functional description
5.1 Analog Inputs
The analog inputs of the µCROS SL are semi-differential inputs with a input range of ± 2 V
between Analog IN CHx GND and the negative power supply UB- and a range of 0 V to
40 V between Analog IN CHx + and Analog IN CHx GND. The Analog IN CHx GND pins
are independent of each other so a differential voltage between each of the pins as well
as UB- is acceptable as long as it stays within the ± 2 V limit. This design compensates
potential differences between the the µCROS SLs UB- supply and the point of the analog
measurement without compromising the accuracy of the measurement. If the increased
accuracy isn’t needed the Analog IN CHx GND pins may be connected to UB- at the
POWER/CAN/IO connector.
