The battery charger has a 9-pin female connector (connector DB9, see fig..4) on which the analog signals
can be seen and used to monitor and control the equipment.
BASIC STATE OF BATTERY CHARGER
DESCRIPTION
Positive MASTER output (650mA max). By drawing 100mA the error is less than 0.7%.
Positive SLAVE A output (650mA max). By drawing 100mA the error is less than 0.7%.
Not connected or if it present, positive SLAVE B output (650mA max). By drawing 100mA the error is less
than 0.7%.
Basic state of battery charger (20 mA max).
Battery charger total current positive shunt (10 mA max). The transduction ratio is 100mV/100A.
GND signal 1 (V master).
GND signal 2 (V slave A).
GND signal 3 (V slave B, if it present).
