Connecting your accessories to
SO401
in/out connector,
you will implement Single Ended
Input/Output configurations.
Removing all
2 contacts jumpers
inserted between
PL402&PL403
or
PL403&PL404,
the
in/out lines
of our modules will be directly available on
PL402
and
PL404
connectors.
In such a way, you will be able to implement fully Differential Input/Output configurations.
Only with GC864-QUAD/PY-C2 modules the
Ear output
lines are AC coupled.
