Control with HTTP commands
http://<address>/admin/set_variables.cgi?name1=value1[&nameN=valueN]
For values with spaces, encode space as %20. (i.e.: set_variables.cgi?name1=640%20x%20480)
To erase a previously set variable, simply set the variable's name with an empty space.
Example:
"http://192.168.0.129/admin/set_
variables.cgi?gpsvar1=N103%2068201%20W765%2029712&gpsvar2=S490%2018731%
20E756%2019890&gpsvar3=N123%2046891%20W345%2065431&gpsvar4=S767%2033410
%20E770%2004513"
sets:
"gpsvar1" to "N103 68201 W765 29712"
"gpsvar2" to "S490 18731 E756 19890"
"gpsvar3" to "N123 46891 W345 65431"
"gpsvar4" to "S767 33410 E770 04513"
Get variables – syntax and example
A get command returns the value of a variable (called
name
in the syntax). You can return multiple variables
at the same time by separating each variable with an "&" (as shown within the square brackets in the syntax
below).
To "get" a variable (or a list of specified variables), use the following syntax:
http://<address>/admin/get_variables.cgi?name1[&nameN]
Example
: "http://192.168.0.129/admin/get_variables.cgi?gpsvar1"
returns:
"gpsvar1=N103 68201 W765 29712"
To "get" a list of
all
variables saved to your Networked VGA Grid, use the following syntax:
http://<address>/admin/get_variables.cgi
Example
: "http://192.168.0.129/admin/get_variables.cgi"
returns:
"gpsvar1=N103 68201 W765 29712
