NL200/201 Network Link Interface

key and certificate are loaded successfully, the TLS Status field should read
“Initialized”.
To use TCP Encrypted Communication, select the Use IP Connection check box
in DevConfig. Input the NL200/201’s IP address (or press the browse button to
select it from a list of NL200/201s connected to the network) and press Connect.
If the status of the TLS stack is “Initialized”, the NL200/201 will
automatically negotiate a secure TLS connection with DevConfig as
long as the Use IP Connection option is selected.
Encrypted Communication is required to change the TLS Private
Key and/or TLS Certificate via TCP. The private key and
certificate cannot be initialized via TCP, since the connection is not
encrypted. They must be initialized through a direct USB
connection to the NL200/201.
When the NL200/201 is in bridge mode, it cannot be configured via
a network connection. It can only be configured via USB and RS-
232.
8. Applications
8.1 Working Around Firewalls
The NL200/201 can be used to provide a connection between LoggerNet and a
datalogger when both are behind firewalls. The NL200/201 must be on a public
IP address and will act as a common meeting place for all PakBus
communications.

DevConfig (see Section 6,
Configuring the NL200/201 ).

On the NL200 tab:
