GND of the DS1103 is internally connected to PC ground.
VCC pins The following I/O pins provide access to the PC power supply VCC
(5 V):
N
DS1103 and Sub-D connector The DS1103 provides three VCC
lines. The total load of every VCC line (VCC1, VCC2 or VCC3) must
not exceed 500 mA.
CP1103/CLP1103 connector panels All VCC1, VCC2, and
VCC3 lines of the DS1103 are connected on the CP1103/CLP1103
and called VCC. The total load of all connector pins that provide
access to the PC power supply must not exceed 1.5 A (CP1103) or
0.75 A (CLP1103).
