Telnet/TCP Connections
The S530 provides support for Telnet/TCP connections via two internal Ethernet interfaces. Refer to the
menu for information on how to configure these.
All Telnet connections are TCP connections but not all TCP connections are Telnet connections. A Telnet
connection is made to the S530 by using the Telnet protocol and by specifying a TCP port address. ‘Telnet’ refers
to a TCP connection made on port address 23, which specifies that characters are supposed to be handled a
certain way. The S530 supports Telnet connections and also supports some custom assigned port numbers to
facilitate certain connection features.
The following information assumes that you know how to run your computer to establish and use Telnet/TCP
connections and only require the specific information relating to the S530 features. Port numbers below include
"x“ where "x“ is the corresponding S530 file or port number. (ie; 2101 refers to the telnet passthrough connection
made on serial port 1.)
•
Port Address 200x
: A connection to port 200x is just like a regular Telnet connection to port 23, except it
sets the default file for retrieving data or the default port when the
BYPASS
command is given.
•
Port Address 210x
: A connection to port 210x routes you directly to the device connected to the
corresponding serial (I/O) port. A banner message will be displayed indicating you are connected to that I/O
port. To disconnect from this access mode press the <ESC> key twice. Refer to the Passthrough section in
this chapter for more information.
•
Port Address 220x
: A connection to port 220x is referred to as a Real-Time Socket. These are sockets
that are dedicated to exporting data from file "x“ in the S530. If there is any data already stored in a particular
file, it will first be transferred out of the S530 to the user or machine initiating the connection. After all the data
currently in the file is transferred out, any data that is coming into the S530 will be immediately transmitted out
and across this connection. Refer to the
menu for information on how to configure
these.
