6.4 Configuring the NL200/201 via RS-232
Accessing the configuration terminal menu via RS-232 requires the
NL200/201 to be power cycled, so physical access to the device will
be required. A null modem serial cable will be needed; one is not
provided with the NL200/201.

Using a null modem serial cable, connect your computer’s serial port to the
port labelled “RS-232” on the NL200/201.

Connect to the NL200/201 using a terminal emulator. DevConfig’s
“unknown” device type or HyperTerminal are examples of simple terminal
emulators. The default settings for this interface are 115200 baud, 8 stop bits,
no parity, 1 stop bit, no flow control.

Power cycle the NL200/201 and repeatedly press Enter at the terminal.


7. Operation
This section describes how to configure your NL200/201 for different operational
modes. See Section 4,
Overview , for help in determining which mode to use.
7.1 PakBus Router
When the RS-232 or CS I/O port is configured as a PakBus router, the NL200/201
can route packets to other devices in the network that it has in its routing table.
These are devices that the NL200/201 has learned about through beaconing or
allowed-neighbour lists.
Beacon Interval – Devices in a PakBus network may broadcast a hello-message
to other devices in order to determine “neighbour” devices. Neighbour devices
are devices that can be communicated with directly by the current device without
being routed through an intermediate device. A beacon in a PakBus network helps
to ensure that all devices in the network are aware of which other devices are
