network. When a device has a neighbor list or neighbor filter setting filled in
for a port, any device that has an address greater than or equal to 4000 will be
allowed to connect to that device regardless of the neighbor filter.
PakBus/TCP Server Port
This setting specifies the TCP service port for PakBus® communications with
the datalogger. Unless firewall issues exist, this setting probably does not need
to be changed from its default value.
PakBus/TCP Password
Specifies the password that will be used to authenticate any incoming (server)
or outgoing (client) PakBus®/TCP sessions. This password is used by the
server to generate a challenge to any client that connects to the PakBus/TCP
server port. If the client fails to respond appropriately, the connection will be
terminated. If this password is blank (the default value), no such authentication
will take place.
PakBus/TCP Client Address (1-4)
This setting specifies the IP address of an outgoing PakBus®/TCP client
connection that the NL200/201 should maintain. If the connection fails, the
NL200/201 will retry until the connection succeeds. No entry or a setting of
0.0.0.0 specifies that no client connection will be made.
PakBus/TCP Client Port (1-4)
This setting specifies the TCP port of the outgoing PakBus®/TCP client
connection. Typically, it is not necessary to change this entry from its default.

PakBus Routes (read only)
This setting lists the routes that are known to the NL200/201. Each route
known to the NL200/201 will be represented by the following four components
separated by commas and enclosed in parentheses. The description of each
component follows:
Port Number
Specifies a numeric code for the port that the router will use. It will
correspond with one of the following:
0 CS I/O
1 RS-232
100 PakBus®/TCP Connection — If the value of the port number
is 100 or greater, the connection is made through PakBus/TCP.
Via Neighbor Address
Specifies the address of the neighbor/router that will be used to send
messages for this route. If the route is for a neighbor, this value will be
the same as the address.
