The DS1103 provides three VCC lines. The total load of
every VCC line (VCC1, VCC2 or VCC3) must not exceed
0.5 A.
n CP1103/CLP1103 connector panels
The VCC1, VCC2, and VCC3 line of the DS1103 are
connected on the CP1103/CLP1103 and called VCC.
The total load of all connector pins that provide access
to the expansion box power supply must not exceed 1.5
A (CP1103) or 0.75 A (CLP1103).
