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.

(range 1..65535)

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.
