LONG nPixelClockFreq; Pixel clock frequency (MHz)
TCHAR tcRegisterChecksum[ MAX_CHECKSUM_LEN ]; Register chcksum (ASCII hex)

Sequence structure defines:
#define MAX_SEQ_BARCODES 12
#define MAX_NUM_START_CHARS 32
#define SEQ_ALL_LENGTH 9999
Sequence structure masks:
#define SEQMASK_MODE 0x00001 sequenceMode
#define SEQMASK_BARCODES 0x00002 dwNumBarCodes & seqBarCodes[]
#define SEQMASK_ALL 0x00003 Everything
Individual sequence barcode structure:
typedef struct _tagSeqItem
{
LONG nSymId; Symbology identifier SYM_xxxx
LONG nLength; Match length or 9999 to match any length.
TCHAR tcStartChars[ MAX_NUM_STAR1 ]; Matching string (from start)
} SeqBarCode_t, *PSeqBarCode_t;
Sequence structure:
typedef struct _tagHHP_SEQUENCE_MODE
{
DWORD dwStructSize; Size of structure in bytes
DWORD dwMask; Mask of active items
HHP_SEQ_MODES sequenceMode; Disabled/Enabled/Enabled & Required
DWORD dwNumBarCodes; This MUST be sent if sending seqBarCodes
SeqBarCode_t seqBarCodes[ MAX_SEQ_BARCODES ]; Barcodes to sequence in order they are to be
sent
TCHAR tchSeqCmdBlk[ SIZE_OF_SEQUENCE_BLOCK ];
} HHP_SEQUENCE_MODE, *PHHP_SEQUENCE_MODE;
Decode method stucture masks:
#define DCMASK_MAX_MESSAGE_LENGTH 0x00001 Maximum length of decoded string. This item is Read Only.
#define DCMASK_DECODE_MULTIPLE 0x00002 Look for and report all barcodes in captured frame.
#define DCMASK_USE_AIMERS 0x00004 Use aimers when capturing barcodes.
#define DCMASK_PRINT_WEIGHT 0x00008 Relative contrast between barcode and background (0-9).
#define DCMASK_DECODE_METHOD 0x00010 Normal, linear codes only. Fastest (may miss codes at edges
of image).
#define DCMASK_CENTER_ENABLE 0x00020 Only accept barcodes whose boundaries intersect center win-
dow.
#define DCMASK_CENTER_WINDOW 0x00040 Rectangle about center of image for previous mask.
#define DCMASK_ILLUMINAT_LED_COLOR 0x00080 Illumination LED color to use.
#define DCMASK_ALL 0x000ff All structure members are active.
Decoder functionality settings:
typedef struct _tagHHP_DECODER_CONFIG
{
DWORD dwStructSize; Size of structure in bytes.
DWORD dwMask; Mask of active items.
DWORD dwMaxMsgSize; Maximum length for any returned barcode string. This is a read
only value.
BOOL bDecodeMultiple; Decode and send all symbols decoded with first frame where at
least 1 symbol is found.
