The compare tool compares the calculated Cyclic Redundancy
Check (CRC) of the configuration stored in the project database with
the CRC of the configuration stored in the Reader. Compare is
useful when checking if a Reader’s configuration has been changed
to determine if an upload or download is necessary.
Note: Reader configurations cut and copied between projects may
not match when compared due to differences in the label
configurations between projects.
To use compare:
1. Make sure the software is on-line by clicking the Go On-Line
icon or by selecting Go On-Line from the Communications
menu.
Note: The Query dialog may be displayed when you go on-line
(depending on your preference settings). Refer to page 2–19.
2. Select the Reader configuration you want to compare with the
actual configuration stored within the Reader.
3. Click the Compare tool icon or select Compare from the
Communications menu.

If the Reader configuration has been compared and does not match

configuration stored in the Reader, the database and connection icons
appear green.

stored in a Reader, the database and connection icons appear yellow.
