1 Optional output from monitor.
2 Note: The IEEE-1394 internal cable bundle
needs an outer shield to minimize internal
crosstalk within the cable construction. The outer
EMI containment shield for the IEEE-1394 func-
tion will be provided by the overall P&D cable
shield. If the internal bundle shield for IEEE-1394
is required, this may be terminated to pin #18. It
is recommended that this implementation be
evaluated in the case where both Charge Power
return and the IEEE-1394 internal cable bundle
shield will be commoned to pin #18.
