NL200 Network Link Interface

standard IP connection. Once the private key and certificate are loaded

successfully, the TLS Status field should read “Initialized”.

You are then able to open a secure browser connection to your datalogger.

HTTPS is the only protocol that is currently supported. (FTPS,

Telnet SSL, and others are not supported.)

NOTES

See your datalogger manual for more information on using

HTTPS with your datalogger.

7.4.2 DevConfig TCP Encrypted Communication to the NL200

In order to use DevConfig TCP Encrypted Communication to the NL200, you

will need to load your TLS Private Key and TLS Certificate into the NL200.

This is done from the Settings Editor | TLS tab in DevConfig. Once the private

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’s IP address (or press the browse button

to select it from a list of NL200s connected to the network) and press Connect.

If the status of the TLS stack is “Initialized” then the NL200 will

automatically negotiate a secure TLS connection with

DevConfig if the Use IP Connection option is selected.

NOTES

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.

When the NL200 is in Bridge Mode, it cannot be configured via

a network connection. It can only be configured via USB.

7.4.3 TLS Serial Server

The NL200 supports connections from TLS clients. However, Campbell

Scientific does not have any applications that support TLS. Therefore, the TLS

client must be supplied by the user.

In order to use TLS Serial Server, you will need to load your TLS Private Key

and TLS Certificate into the NL200. This is done from the Settings Editor |

TLS tab in DevConfig. Once the private key and certificate are loaded

successfully, the TLS Status field should read “Initialized”.

You can then use DevConfig to set your RS-232 port or CS I/O port to TLS

Serial Server.

Your user-supplied client will then be able to connect the NL200’s TLS Serial

Server.
