Smart Battery (BattMan) Interface (CN5)
Table 3-5 lists the pin signals of the Smart Battery header, which provides 10 pins in 2 rows,
odd/even pin sequence (1, 2), and 2.54mm pitch.
NOTE: The # symbol indicates the signal is Active Low. Shaded table cells denote power or
ground.

Table 3-6 lists the pin signals of the Post Code Enable jumper header, which provides 3 pins in a
single row with 0.079" (2.00mm) pitch.
NOTE: The shaded table cells denote ground.
You must configure the jumper settings as

occur when using a BattMan power supply to
Power On the carrier.
