7.6.2 XDSCAP Program
This program performs the task of XDS data recovery. XDS recovery must first be
enabled through the appropriate XDS Filter command. Script file examples for
setting the XDS Filter are shown below.
The program is invoked by typing: SI File_name <ENTER>
When the program is invoked, the PC screen displays:
EEG CCD2 XDS Data Recovery Test Program Version x.xx
Slave Address is 28h
The responding slave address is reported to the screen.
When communication is acknowledged, the program displays all XDS data recov-
ered from those packets that were enabled through the XDS Filter command:
{01,03}Current Program{00}{0F,7F}....etc
The ASCII characters are displayed as ASCII characters, while the nonprinting char-
acters are displayed by their Hex values within curly braces. Byte pairs, such as
Class, Type, are shown as pairs within the curly braces, separated by a comma, for
example: {01,03}.
If no data is received within approximately 45 seconds, the program times out,
reports Data Not Available, and exits.
NOTE: The XDSCAP program can also be exited by entering a Control+C (^C) character.
