  • Page 5: Internal Data Buffer

    Internal data buffer  KDC200 has 200K bytes flash memory where it stores the read barcodes. Its capacity, in terms of number of barcodes, depends on the size of barcodes. Barcodes are stored sequentially as they are scanned in the internal flash memory.

  • Page 6: How Many Barcodes Can We Store

    Therefore, KDC200 can store 10,240 UPCA barcodes. If different length barcodes are mixed, user cannot compute a priori what the maximum number of barcodes is. What happens when this buffer is full?  When the internal flash memory is full, KDC200 displays buffer full message and ignores the command to scan barcodes.

  • Page 7: Command Set

    Command Set  KDC200 has various commands and they are quite simple. They are shown in the following table. Command Input Output Description Returns current battery capacity(value = 0-100) None value @ Returns current settings of Bluetooth options. None value @ Turns off Bluetooth power...

  • Page 8: B' Command

    Parameters: None Format: ‘B’ Output: ‘xxxx@’ where xxxx is the capacity of battery ( 0 – 100) in hex and @ means the end of data Purpose: Read the battery capacity of KDC200. ‘bT0’ command  Parameters: None Format: ‘bT0’ Output: ‘xx@’ where xx(1 byte) is the current selected Bluetooth options.

  • Page 9: Bt3' Command

    Parameters: 0 or 1 Format: ‘bT30’ or ‘bT31’ Output: ‘@’ if successful. ‘!’ if failed. This command is failed if sent when KDC200 is connected to HOST. Purpose: Enables(1)/Disables(0) KDC200 to try to connect to Bluetooth HOST automatically after power on. ‘bT4’ command ...

  • Page 10: Bt70' Command

    5 minute if value is 0 and 30 if value is greater than 30.  ‘C’ command  Parameters: Date and Time value to be set in KDC200 Format: ‘CYMDHmS’ where Y is year(0 means 2000), M is month(1-12), D is day(1-31), H is hour(0-23), m is minute(0-59) an S is second(0-59).

  • Page 11: D' Command

    Parameters: None Format: ‘D’ Output: ‘!’ – KDC200 internal flash memory is full or Reading failure ‘@’ – Barcode reading success Purpose: Turns the motor on, then turns the laser on and starts scanning. When a barcode is found or if timeout occurred, it stops the motor and turns off laser.

  • Page 12: H' Command

    “Hxxxx#” where xxxx is the value of parameter in hex. Output: ‘!’ – invalid parameter. ‘@’ – all other times. Purpose: Selects if KDC200 need(1)/doesn’t need(0) to handshake with HOST while sending packet data. KDC200 doesn’t do handshake if sending barcode only. ‘h’ command  Parameters: None Format: ‘h’...

  • Page 13: L' Command

    ‘N’ Output: ‘xxxxxxxx@’ where xxxxxxxx is the number of stored barcodes and @ means the end of data Purpose: Read the number of stored barcodes in KDC200 internal flash memory  ‘O’ command  Parameters: The options (it is unsigned 32-bit number) Format: ‘Oxxxxxxxx#’...

  • Page 14: O' Command

    ‘o’ Output: ‘xxxxxxxx@’ where xxxxxxxx is the selected barcode options and @ means the end of data Purpose: Read the barcode options saved in KDC200. Please see the table of command ‘O’ for detail explanation of options ‘P’ command  Parameters: None.

  • Page 15: P' Command

    Output: A multi-byte string (see below). KDC200 sends only one barcode data at one time. Purpose: Read the Nth barcodes data stored in KDC200 internal flash memory. Does not erase the barcode. Where: S : Start byte 0x03(1 byte) N : Total number of bytes to be sent(3 bytes)

  • Page 16: S' Command

    KDC200 Programming Manual ‘S’ command  Parameters: The symbology selection (it is unsigned 32-bit number) Format: ‘Sxxxxxxxx#’ where xxxxxxxx is the value of parameter in hex. Output: ‘!’ – invalid parameter. ‘@’ – all other times. Purpose: Enables the selected symbologies. Example: Sending “Sffffffff#”...

  • Page 17: T' Command

    Purpose: Selects how KDC200 handles scanned barcode. If the value xxxx is 0: KDC200 doesn’t store scanned barcode in the memory and just transmits it to the host. 1: KDC200 stores scanned data in the memory and transmits it to the host.

  • Page 18: W' Command

    ‘@’ – all the times. Purpose: Wake up KDC200 from sleep mode. To ensure that KDC200 woke up from sleep, it is required to send ‘W’ command many times. If KDC200 replied with ‘@’, then KDC200 is already woke up from sleep mode. ‘w’ command ...

  • Page 19: Z' Command

    Where: Barcode data is the actual read barcode data CR is 0x0d(‘\r’) LF is 0x0a(‘\n’) PACKET DATA Where: S : Start byte 0x03(1 byte) N : Total number of bytes to be sent(3 bytes) C : Total number of each barcode data(1 byte) Y : Type of each barcode(1 byte) D : Actual barcode data of each barcode(variable size) T : Timestamp of each barcode(4 bytes)
  • Page 20 KDC200 Programming Manual...

  • Page 21: Packet Data

    Wedge mode If KDC200 read a barcode and configured to send packet data, KDC200 waits for 1 second to get a response from HOST after sending a read barcode data to HOST. KDC200 goes to ready mode upon receiving either success or failure response.

  • Page 22: Synchronization Mode

    KDC200 exits waiting state if it receives any response from HOST. KDC200 replies to HOST with sending ‘@’ for a success response. KDC200 waits for 1 second and exits waiting state with sending a ‘!’ to HOST if there is no response from HOST.

  • Page 23: Miscellaneous

    KDC200 sends one to three leading “NULL” bytes with barcode payload or packet KDC200 Bluetooth module goes to sleep mode if not used for a while. KDC200 sends out one to three NULL bytes to wake up Bluetooth module before sending out barcode payload or packet. Application should ignore...
