Appendix C. NL240 Settings
TLS Proxy Server Port Number
When doing TLS Proxy communications, the NL240 TLS server maintains a
secure connection with a remote client. If the TLS Proxy Forward Physical
Port is specified to be the CS I/O port, the NL240 will then open a TCP
connection with the logger over the CS I/O port and do unecrypted data
transfer with the datalogger. If the TLS Proxy Forward Physical Port is
specified to be Wi-Fi, the NL240 will open the TCP connection over Wi-Fi on
the TLS Proxy Forward IP Address.
In order to communicate with the NL240 TLS server, the client application
must open a socket to that server. The socket of the NL240 TLS server is
uniquely identified by the IP address and a port number. This entry is where
the port number of the NL240 TLS server is set.
The TLS client needs to be set to communicate on this port number. If secure
communications come in on the Secure Proxy Server Port Number, the NL240
will attempt to open a TCP connection to the datalogger on the Secure Proxy
Forward Port Number. Also, regardless of this setting, the NL240 Secure
Proxy Server will always listen on the secure HTTP (HTTPS) port number
443. If a secure connection is established on this port, the NL240 will attempt
to communicate to the datalogger on the HTTP port 80. (range 1..65535)
TLS Proxy Forward Physical Port
When doing TLS Proxy communications, the NL240 TLS server maintains a
secure connection with a remote client. If the TLS Proxy Forward Physical
Port is specified to be the CS I/O port the NL240 will then open a TCP
connection with the logger over the CS I/O port and do unecrypted data
transfer with the datalogger. If the TLS Proxy Forward Physical Port is
specified to be Wi-Fi, the NL240 will open the TCP connection over Wi-Fi on
the TLS Proxy Forward IP Address.
TLS Proxy Forward IP Address
Secure communications received on the NL240 TLS Server will be forwarded
on a non-secure TCP connection to this IP address. If the TLS Proxy Forward
Physical Port is specified to be the CS I/O port, this setting is not set by the user
since the NL240 will obtain the IP address of the datalogger automatically. If
the TLS Proxy Forward Physical Port is specified to be Wi-Fi, the forward IP
address must be specified. Enter the IP address of the destination datalogger
here.
TLS Proxy Forward Port Number
When doing TLS Proxy communications, the NL240 TLS server maintains a
secure connection with a remote client. If the TLS Proxy Forward Physical
Port is specified to be the CS I/O port, the NL240 will then open a TCP
connection with the datalogger over the CS I/O port and do unecrypted data
transfer with the datalogger. If the TLS Proxy Forward Physical Port is
specified to be Wi-Fi, the NL240 will open the TCP connection over Wi-Fi on
the TLS Proxy Forward IP Address.
In order to communicate with the connected datalogger’s TCP server, the
NL240’s TCP client application must open a socket to that server. The socket
