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
PC power supply must not exceed 1.5 A (CP1103) or 0.75
A (CLP1103).
Slave I/O Connector (CP31)
The slave I/O connector (CP31) is a 37-pin, female Sub-D connector
located on the front of the connector panel.
Objective
Because the pin numbering used for Sub-D connectors is not
standardized, the following figure shows the numbering scheme used
(front view).
Do not rely on the numbers written on Sub-D
connectors.
