2.2 Communication with the NL100/105
2.2.1 Establishing the Initial Communication
Once the physical connection has been made, communication should be
established with the NL100/105 using a terminal communications package. The
steps below demonstrate configuring the NL100/105 using HyperTerminal,
which is shipped with Windows operating systems.
The NL100/105 is shipped from the factory with its RS-232 port
set in the ConfMon mode (configuration monitor). Refer to
Section 2.2.2 if the RS-232 port has been set to some other
configuration and direct communication is necessary.
Ensure the NL100/105 has an appropriate power source applied. (Refer to
Section 2.1, above.)
Create a new connection in HyperTerminal. Choose the COM port to which the
null-modem cable is connected, and set the baud rate to 115,200 bps. Most of
the other settings can be left at the default (data bits = 8, parity = none, stop bits
= 1). Flow control should be set to none.
Once HyperTerminal indicates you are connected, press <Enter> a couple of
times to gain the attention of the NL100/105. When communication is
established, the current port settings will be returned, followed by the
NL100/105 prompt line:
NL100/105 (ver, show, edit, defaults, reset, help, bye):
To set up the NL100/105 for communication with the network, go into the Edit
menu (Section 2.3.3 Edit) and complete the appropriate information. Note that
the Ethernet 10 Base-T connection must be configured (Section 2.3.3.5) and at
least one of the other port options.
2.2.2 Establishing Communication Outside of ConfMon Mode
If the RS-232 port has been disabled or set to some configuration other than
ConfMon, communication can still be established with the NL100/105 by
connecting the boot jumper.
To access the boot jumper, remove the NL100/105's cover by removing the
four screws at the corners.
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.
