B.7 Power Jumper (NL201 only)
If you wish to prevent the NL201 from being powered over the CS I/O port,
remove the two screws on the top of the NL201, remove the NL201’s top cover,
remove the jumper indicated below and place it so that it is connected to only one
post. With the jumper connected to only one post, the NL201 can only be powered
from the barrel connector. With the jumper connected to both posts, the NL201
can be powered from the CS I/O port or from the barrel connector.
