5.1. Connecting with clip wires
For manual connection use set of clip wires which are delivered with the IOM6 ADIO package.
NOTE: Make sure that the Embedded system and BlueBox are not powered.
For voltage measurement
1. Connect GND from the Power Sense connector to the circuit ground of the Embedded
system.
2. Connect AIN input from the Power Sense connector to the supply voltage of the Embedded
system.
3. If the voltage is higher than 5V, use a suitable resistor divider. Enter the divider ratio as a
Voltage/Multiply factor in winIDEA configuration dialog.
For current measurement
1. Connect GND from the Power Sense connector to the circuit ground of the embedded
system.
2. Connect RS+ signal pin from the Power Sense connector to a high side of the shunt (see
Picture 2).
3. Connect RS- signal pin from the Power Sense connector to a low side of the shunt (see
Picture 2).
4. Specify the resistance of the R shunt resistor in winIDEA configuration dialog.
5. Switch ON BlueBox and embedded system power supply.
Picture 2 depicts power measurement setup. Connect with clip wires where blue arrows
indicate.
NOTE: The full-scale shunt voltage range is 250mV (e.g. a 1Ω shunt resistor gives a current
range of 250Ma).
Full-scale Shunt Voltage Shunt Resistance Full-scale Current Range Shunt Power Dissipation
