A.4 Power jumper
To prevent the NL241 from being powered over the CS I/O port, remove the two screws on the
top of the NL241, remove the NL241 top cover, remove the jumper above the mode button and
place it so that it is connected to only one post. With the jumper connected to only one post, the
NL241 can only be powered from the barrel connector. With the jumper connected to both posts,
the NL241 can be powered from the CS I/O port or from the barrel connector.
