Front Connector Pin Assignment and Labeling on the CP 343-2
The CP 343-2 has internal contacts for two AS-i cables that are jumpered internally
on the CP. This allows the CP 343-2 to be "looped" into the AS-i cable.
Notice
The load capacity of the contacts is a maximum of 4 A. If this value is exceeded
on the AS-i cable, the CP 343-2 must not be "looped into" the AS-i cable but must
be connected by a separate cable (only one pair of contacts used on the
CP 343-2).
For further information on connecting the AS-i cable, refer to Section 2.2.
