Note
In a DM frame, you can create
looping inputs by adding a
T-connector on the input
connection and changing the
input termination mode jumper
setting to external termination.
(The internal termination setting
is used for non-looping inputs.)
For BMFL modules, the input
termination jumper default
mode is for external
termination. This is the setting
you will need if you are using a
looping input.
