C:\MyData\sn_timestamp.txt is Figure 21 - KTSync® Synchronization Settings$

KDC User Manual 61 Revision 3.05.R6 Copyright ® 2014, KoamTac, Inc. the default directory. If this directory is not created, you will be prompted to create it before data can be uploaded to a file.  Active Window - This option means scanned barcode data is sent directly to the active program running on your device as if the data was being entered directly from a keyboard.  Microsoft Excel - This option means barcode data is being imported directly into Microsoft’s Excel. Various parameters can be set when uploading data to Excel.  Select from Current Running Application – This option allows you to select a currently running application for data synchronization. Note: • Data synchronization begins immediately if Automatically After Connection is selected. If not selected, data synchronization is started manually by the user. • Users SHOULD NOT operate the PC during the synchronization process. It can interrupt the process causing unreliable results. 5.3.2 Synchronization Methods Fast Synchronization in Burst Mode The KDC can synchronize data to a host device in Burst mode or Sequential mode. Burst mode provides the fastest synchronization process but could result in error in a poor Bluetooth environment. Fast synchronization in burst mode is only recommended with USB connection. Synchronize Normal Data The KDC will synchronize Normal Data only in KDC memory if Synchronize Normal Data option is selected. If you want all data in KDC memory synchronized, you should select Synchronize Normal Data and Synchronize Application Data. Synchronize Application Data The KDC will synchronize Application Data only in KDC memory if Synchronize Application Data option is selected. If you want all data in KDC memory synchronized, you should select Synchronize Normal Data and Synchronize Application Data. Clear KDC Memory after Synchronization The stored barcode data is cleared from the KDC memory after synchronization if this option is selected.

Synchronization of date and time occurs after the data is uploaded to the host device. Delays You can set transmission delays between barcodes and characters during the synchronization process. It is important to set proper delays to prevent errors during the transmission of collected barcodes. Some Windows applications such as Excel require longer delay times. Attachments Timestamp, Barcode Type, and Serial Number can be attached to the scanned barcode by selecting these options. The Serial Number of the KDC can be attached to the Start or End of Record. Prefix and Suffix  Enter the characters you want appended to the front (Prefix) or back (Suffix) of the barcode in the Prefix and Suffix fields.  The character set is any combination of ASCII characters including alphanumeric, line feed (“\n”), and carriage return (“\r”). Order and Delimiter  Select Order of Data – Type, Data, and Timestamp  Select the Delimiter between Data – Tab, Space, Comma, and Semicolon  Select the Delimiter between Records – None, LF, CR, Tab, and <LF & CR> 5.3.5 Application Options Synchronize Non-Compliant Data The KDC will synchronize both compliant and non-compliant data (filtered data) if Synchronize Non-Compliant Data option is Enabled. Consolidate Steps in One Record KTSync will consolidate the data collected in Step 1 with the data collected in Step 2 and/or Step 3. Data will be consolidated into one record instead of individual data records for each step when Consolidate Steps in One Record is Enabled. Non-complete records, i.e. three steps were defined but data was only collected for two steps; would be discarded if this option is Enabled. Attach Quantity Quantity would be attached to the left or right of the data if this option is Enabled.$
