Use the read configuration command to read configuration data for the
specified blocks (Upload Configurations). The command has the following
structure:
>RC,CBn [CR]
Where n = 1 to 213 (individual blocks)
X – Y (range of blocks X through Y)
* (all of the blocks)
This function can only be executed once per command.
Refer to Appendix C for a description of the configuration blocks. You
cannot use this command while the Color CVIM module is in the SETUP
mode.
Examples:
>RC,CB135 [CR] Reads configuration block 135.
>RC,CB99,CB7,CB1[CR] Reads configuration blocks
1, 7, then 99.
>RC,CB1–213[CR] Reads all of the configuration
blocks .
After executing a command, the Color CVIM module will return: [CR][LF]
followed by the data. If you do not have the proper command structure, the
Color CVIM module will return: ?[CR][LF]. The format of the requested
data is in an ASCII representation of the specified block(s) in bytes. Each
byte is represented by two hexadecimal characters (00 through FF) followed
by a space. The first two words are the signature word indicating block type
and number (refer to appendix D). Twenty bytes of data are transmitted in a
line terminated with a [CR][LF]. The size of the configuration block(s)
determines the number of lines that are returned.
