NL100/105 Network Link Interface
The boot jumper is shown in Figure 2 below. The NL100/105 ships with this
jumper connected to only one post. Place the jumper so that it connects the two
posts.

FIGURE 2. NL100/105 Jumper Placement
When the jumper is in place, open the HyperTerminal connection to the
NL100/105 and power up the device. The prompt "NL100 boot" will appear.
At this prompt, press <Enter> a few times to ring up the NL100/105. If
communication is successfully established, a message will be returned
indicating that the NL100/105 is initialized, along with the jumper setting (1 =
on, 0 = off), the TCP/IP address, Telnet port address, and current
communication configuration. If <Enter> is pressed again, the NL100/105
menu prompt will appear.
After reconfiguring the NL100/105 for communication,
the jumper should be disconnected. If this jumper
remains in place and power to the NL100/105 is cycled
off and back on, the NL100/105 will remain at the
"NL100 boot" prompt and will not boot up. This will
render the NL100/105 inaccessible via remote
communications. WARNING
