Disable Character

Specifies the value of the USB-COM host command used to disable the reader.

ASCII characters or any hex value from 0 to 0xFF can be selected.

To set the value:

1. Determine the desired character or value. A setting of 0xFF indicates the Disable Character is not used

(not available).

2. Use the ASCII Chart on the inside back cover of this manual to find the hex equivalent for the desired

character/value.

3. Go to page 20 and scan the ENTER/EXIT PROGRAMMING MODE barcode to enter Programming

Mode.

4. Scan the barcode: SELECT DISABLE CHARACTER SETTING.

5. Scan the appropriate two alphanumeric characters from the keypad in Appendix D, Keypad, that repre-

sent the desired character/value in step 1 above. The second character will cause a two-beep indication.

6. Scan the ENTER/EXIT PROGRAMMING MODE barcode to exit Programming Mode.

This completes the procedure. See Table 30 for some examples of how to set this feature.
