datalogger. If the TLS Proxy Forward Physical Port is specified to be the Ethernet
port, the NL200/201 will open the TCP connection over Ethernet on the TLS
Proxy Forward IP Address.
In order to communicate with the NL200/201 TLS server, the client application
must open a socket to that server. The socket of the NL200/201 TLS server is
uniquely identified by the IP address and a port number. This entry is where the
port number of the NL200/201 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
NL200/201 will attempt to open a TCP connection to the datalogger on the Secure
Proxy Forward Port Number. Also, regardless of this setting, the NL200/201
Secure Proxy Server will always listen on the secure HTTP (HTTPS) port number
443. If a secure connection is established on this port, the NL200/201 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 NL200/201 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 NL200/201 will then open a TCP connection
with the datalogger over the CS I/O port and do unencrypted data transfer with the
datalogger. If the TLS Proxy Forward Physical Port is specified to be the Ethernet
port, the NL200/201 will open the TCP connection over Ethernet on the TLS
Proxy Forward IP Address.
TLS Proxy Forward IP Address
Secure communications received on the NL200/201 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 NL200/201 will obtain the IP address of the datalogger automatically. If
the TLS Proxy Forward Physical Port is specified to be the Ethernet port, 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 NL200/201 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 NL200/201 will then open a TCP connection
with the datalogger over the CS I/O port and do unencrypted data transfer with the
datalogger. If the TLS Proxy Forward Physical Port is specified to be the Ethernet
port, the NL200/201 will open the TCP connection over Ethernet on the TLS
Proxy Forward IP Address.
In order to communicate with the connected datalogger’s TCP server, the
NL200/201’s TCP client application must open a socket to that server. The socket
of the datalogger’s TCP server is uniquely identified by an IP address and a port
number. This entry is where the port number of the NL200/201’s TCP client is
set. The datalogger’s TCP server port must be set to communicate on this port
number.
If secure communications come in on the TLS Proxy Server Port Number, the
NL200/201 will attempt to open a TCP connection to the datalogger on the TLS
Proxy Forward Port Number. Also, regardless of this setting, the NL200/201 TLS
Proxy Server will always listen on the secure HTTP (HTTPS) port number 443. If
a secure connection is established on this port, the NL200/201 will attempt to
communicate to the datalogger on the HTTP port 80.
