*1) Each of the connectors,
CNUSR11 and CNUSR12, are
assigned with the same pin
number, creating 2 systems in
each terminal. It is absolutely
necessary to connect the 2
systems.
*2) You can see in the diagram that
connector CNUSR2 has 2
terminals and 2 systems (16/17
indicates 2 terminals at pin
number 16 and pin number 17).
It is absolutely necessary to
connect the 2 systems.
