Campbell Scientific NL100 Network Link Interface - Manual (Page 17)

NL100/105 Network Link Interface
Config” option must be enabled (Section 2.4.3.7) or you will not be able to
communicate with TCP/IP through the NL100/105 to the PakBus devices on
that port.
When configured for PakBus, the NL100/105's RS-232 port has the following
settings:
RS-232 bps - This is the bits per second (bps) at which the NL100/105
will communicate using the RS-232 port. This is a fixed rate (i.e., it is not
a maximum baud rate or an autobaud rate). Note that the CR10XTD-PB
and the CR510TD-PB can communicate at a maximum baud rate of 9600
bps, so to communicate with one of those dataloggers, this setting must be
9600 bps or less. The default rate is 115K bps.
PakBus Beacon Interval - The NL100/105 can be set to transmit a beacon
to a PakBus network via the selected port. The beacon allows the
NL100/105 to determine which devices in the PakBus network it can
communicate with. Note that because a beacon is broadcast to all devices,
it can interfere with other communication in the network (such as RF), so
a frequent beacon may not be desirable. If 0 is entered, no beacon will be
sent; the default beacon is 60 seconds.
RS232 Verify Interval - This is the interval at which a PakBus
communication link will be verified over the RS232 port. If
communication does not take place with a PakBus device within the
verify internal, a packet will be sent to test the communication link. In
most instances, this setting should be left at the default of 0, which will
set a verify interval of 2.5 times the Beacon Interval.
If both the beacon interval and verify interval are set to 0, a verify interval
of 5 minutes will be used.
RS232 Neighbor list - Enter a list of addresses for PakBus devices with
which the NL100/105 can communicate over the RS232 port. The
addresses are specified individually, with a space separating each address,
or a range of addresses can be entered by separating them with a hyphen
(e.g., 1 3 6 10-15, sets PakBus addresses 1, 3, 6, 10, 11, 12, 13, 14, and 15
as neighbors). If a Neighbor list is entered, the NL100/105 will ignore
packets from any device which is not in the list (unless the address of the
device sending the packet is 4000 or greater). If 0 is entered for this
parameter, the NL100/105 will respond to any device that sends a packet
and will automatically add that device to its neighbor list.
TcpSer - This option configures the NL100 to act as a TCP/IP based serial
server when communicating with a datalogger over its RS-232 port.
RS-232 bps - This is the bits per second (bps) at which the NL100/105
will communicate using the RS-232 port. This is a fixed rate (i.e., it is not
a maximum baud rate or an autobaud rate). Note that the CR10(X),
CR510, and CR200 can communicate at a maximum baud rate of 9600
bps, so to communicate with one of those dataloggers, this setting must be
9600 bps or less. The default setting is 115K bps.
