router to allow scheduled collection of a network of data loggers every 15 minutes, consider
setting the Verify Interval to 30 minutes.
Neighbors Allowed (RS-232 port only) – Used to set a list of “acceptable neighbors” which the
NL241 expects to hear from within set intervals (the verify interval). If the NL241 does not hear
from neighbors in this list within the verify interval, it will attempt to contact them on its own. It
will ignore all devices it hears that are not on the Neighbors Allowed list except if the PakBus
address is ≥4000. Following a hello message, devices with PakBus addresses ≥4000 are
automatically accepted as neighbors.
8.2.1.1 Physical setup
Using the supplied serial cable, connect the NL241 CS I/O port or RS-232 port to the data logger
CS I/O or RS-232 port, respectively. The NL241 will be powered if connected via CS I/O.
Alternatively, power the NL241 through the barrel-connector jack located on the edge of the
device. Connect the NL241 to your local wireless network by attaching an antenna to the NL241
Antenna connector. Ensure that the device is powered up by inspecting the LED.
8.2.1.2 Configuring the NL241
RS-232 PakBus router
1. Connect to the NL241 in
Device Configuration Utility
(see
2. On the NL241 tab, set Bridge Mode to disable.
3. On the RS-232 tab:
a. Set Configuration to PakBus.
b. Set Baud Rate to baud rate of attached device.
c. Set Beacon Interval, Verify Interval, and PakBus Neighbors Allowed as described
above. Often, the default values can be used. However, an allowed neighbors list can
be useful in restricting communications paths.
4. On the Network Services tab, make note of the PakBus/TCP Service Port. (The default
PakBus/TCP Service Port is 6785. Unless firewall issues exist, it is not necessary to change
the port from its default value.)
