existing resource.
^RSR

refresh rate for a

^RAF, ^RMF - Embedded Codes
The ^RAF and ^RMF commands add and modify any and all resource parameters by sending embedded codes
and data:
"'^RAF-<resource name>,<data>'"
"'^RMF-<resource name>,<data>'"
The <data> variable uses the embedded codes described in the following table:
^RAF, ^RMF - Embedded Codes
Parameter Embedded Code
protocol
user
password
host
file
path
NXD-430/NXD-435 4.3" Wall/Flush Mount Touch Panels
Modifies any and all resource parameters by sending embedded codes and data.
Since the embedded codes are preceded by a '%' character, any '%' character contained
in the URL must be escaped with a second '%' character (see example).
The file name field (indicated by a %F embedded code) may contain special escape
sequences as shown in the ^RAF, ^RMF - Embedded Codes section on page 107.
Syntax:
"'^RMF-<resource name>,<data>'"
Variables:
• resource name = 1 - 50 ASCII characters
• data = Refers to the embedded codes, see the ^RAF, ^RMF - Embedded Codes section
on page 107.
Example:
SEND_COMMAND Panel,"'^RMF-Sports_Image,%ALab%%5FTest/
Images%Ftest.jpg'"
Changes the resource 'Sports_Image' file name to 'test.jpg' and the path to 'Lab_Test/
Images'.
Note that the %%5F in the file path is actually encoded as %5F.
Syntax:
"'^RSR-<resource name>,<refresh rate>'"

resource name = 1 - 50 ASCII characters.
refresh rate = Measured in seconds.
Example:
SEND_COMMAND Panel,"'^RSR-Sports_Image,5'"
