Campbell Scientific NL100 Network Link Interface - Manual (Page 20)

NL100/105 Network Link Interface
take place over a port other than the Ethernet connection, this setting can be
disabled. When enabled, there is one option to configure:
PakBus/TCP server port number - Enter the port number, in the range
of 1 to 65000, that will be used for communication. The default port
number is 6785.
2.4.3.8 PakBus/Tcp Client Config
Enabling this option will set up the NL100/105 to act as a client in a PakBus
network. In this mode, the NL100/105 will actively maintain a TCP/IP
connection with a PakBus/Tcp server over the 10 Base-T connection.
Server IP Address - The Server IP address is the address of the server
to which the NL100/105 will attempt to connect and act as a client.
Server IP Port Number - The Server IP port number is used to specify
the port number of the PakBus/TCP server to which the client will
attempt to connect.
This option is typically used when the NL100/105 is configured to
communicate with another NL100/105 over an Ethernet connection, so that the
two PakBus networks served by the NL100/105s can be merged. In most
situations, this setting can be disabled.
2.4.3.9 MODBUS/TCP Gateway Config
When this setting is enabled, the NL100/105 will translate MODBUS/TCP
packets that arrive on the 10 Base-T link for use in a PakBus network. The
translation provided by this mode is MODBUS/TCP message format to
MODBUS RTU serial message format. Unless you are setting up a PakBus
network to also handle MODBUS communication packets, this setting can be
disabled.
2.4.3.10 Telnet IP Port Number
This setting is used to specify the IP port number that will be used for Telnet
sessions with the NL100/105. The default value is 23.
Telnet Session Password - The Telnet Session Password is the string
that must be entered to communicate with the NL100/105 over a
Telnet session. The string can range from 1 to 20 alphanumeric
characters and is case-sensitive. This security measure is
implemented to help prevent unauthorized users from gaining access
to the NL100/105 device.
2.4.3.11 DevConfig Security Code
Campbell Scientific's Device Configurator (or DevConfig) is an application
that is used to configure dataloggers and peripheral devices for communication
and to download new operating systems. A security code can be set in the
NL100/105 so that communication using DevConfig is not possible unless the
security code is sent when the application tries to communicate with the
device. This security code helps to prevent unauthorized changes to a device.
