... Adjacent input channels are paired; moving the jumper changes both of the paired channels (LN4_IN–LN5_IN), and moving the jumper on JP24 changes LN0_IN– LN1_IN and LN2_IN–LN3_IN. At the present time Rabbit Semiconductor does not offer the software drivers to work with single-ended negative voltages, but the differential mode described below may be used to measure negative voltages ...

... NOTE: Remember to cycle the main power off/on any time the RCM4200 is removed from the Prototyping Board or motherboard since that is where the backup battery would be located. Rabbit Semiconductor’s Technical Note TN235, External 32.768 kHz Oscillator Circuits, provides additional information about the current draw by the real-time clock oscillator circuit. ...
