Net F/T Installation and Operation Manual

8. Common Gateway Interface (CGI)
The Net F/T can be configured over Ethernet using the standard HTTP get method, which sends configuration
variables and their values in the requested URL.
Each variable is only settable from the CGI page which is responsible for that variable. The following tables list
each CGI page and the settable variables associated with it.
URLs are constructed using the syntax:
http:///?
where:
http://
indicates an HTTP request
is the Ethernet address of the Net F/T system
/ a separator
the name of the CGI page that holds the variables you will be
accessing
? a separator marking the start of variable assignments
a variable assignment using the format described below
a variable assignment using the format described below, but the
variable name is proceeded by an ampersand. This variable
assignment is optional and may be repeated for multiple variables.
Variables are assigned new values using the syntax:
variableName=newValue
where:
variableName
is the name of the variable to be assigned
= indicates assignment
newValue
is the value to be assigned to the variable. Text for text variables
should not be enclosed in quotes. To include the ampersand character
in text for a text variable use %26. Floating point numbers are
limited to twenty characters.
Example:
http://192.168.1.1/setting.cgi?setcfgsel=2&setuserfilter=0&setpke=1
tells the Net F/T at IP address 192.168.1.1 to set CGI variables
setcfgsel to 2, setuserfilter to 0, and setpke to 1.
The maximum length of these URLs may be determined by a number of factors external to the Net F/T.
Exceeding the maximum length may result in an error or variables being incorrectly set.
