KDC User Manual BLUETOOTH
86
The KDC provides two data formats, Barcode Only and Packet Data.
⚫ Barcode Only: The KDC transmits scanned barcodes only. You may incorporate
appropriate data transmission error detection and correction mechanisms in this mode.
KDC supports a selection of various termination characters for Barcode Only format.
You may select <NONE>, <CR>, <LF>, <CR+LF> or <TAB> as the termination
character.
⚫ Packet Data: KDC transmits packet data with checksum to minimize transmission errors.
KTSync sets Data Format to Packet Data format upon execution.
➢ You may change Data Format to Barcode Only if you would prefer to use the
Barcode Only mode. However, the KDC would stay in Packet Data mode if KTSync
is aborted abnormally. If this is the case, you may have to change the KDC back to
Barcode Only mode manually.
• Barcode Index: KDC20i/30i/200i/250i/300i/270i/350i/400i/470i/500i add 4 bytes
barcode index to maintain last synchronized barcode information.
- This optional index would be added if data format is “Packet Data”.
- 4 bytes index would be added before “@” when responding to “p”
command.
- 4 bytes index plus “@” character would be added after checksum byte if the
user scans a barcode and wedges to the host.
Data Editor
The KDC provides various data editing options.
⚫ Prefix - Enables user to add a prefix to scanned data that may then be wedged to the
host. The Prefix must be defined in the KTSync. The maximum length for a Prefix is 11
characters.
This Prefix option is different from the Prefix option in KTSync, which attaches the
prefix to data during synchronization.
The user may also define the prefix by scanning characters defined in Appendix
C&D(E&F for KDC500). as shown below in the special barcodes.
