Pointer to a callback function (see hhpImgrSdk.h) called in response to the completion of an
asynchronous 5X00 Series function call or event. (See example on page 6-4.)
SDK Enumerated Types
Beep Options Enumeration (not an enumerated type) that can be used with an hhpSendActionCommand.
Compression_t
Enumerated type for specifying the form of compression (if any) to use when transferring an
image from the imager to the SDK. See Compression Mode Formats on page 3-4.
ConfigItems_t
Enumerated type to specify that the configuration structure is being sent to the Read/Write
config item functions.
DECODE_METHOD Enumerated type of decode methods available to decode symbols.
DECODER_TYPE Enumeration of types of decoders and, by extension, what symbologies can be decoded.
EngineType_t Describes the connection, the imager, and the type of engine.
FileFormat_t Enumerated type for specifying the format of the data returned in the HHP_IMAGE structure.
HP_ACTION
Enumerated type whose items describe which imager command functionality (beeper, aimers,
lights) is to be acted upon.
HHP_AIMER_MODES Enumerated type to specify the aimer mode.
HHP_AUTOEXPOSURE
Enumerated type to specify whether the imager tries to auto adjust the image exposure and, if
so, how.
HHP_BAUD_RATE
Enumerated type of the supported baud rates for serial devices.
Note: A special driver is required if a baud rate greater than 115200 is selected.
HHP_BEEPER_VOLUME
Enumerated type to select the imager beeper volume when sounding the beeper. This structure
is ignored for products that do not have a beeper.

Enumerated type to specify the behavior of the illumination and aimer LEDs during image
capture.
HHP_EVENT_TYPE Enumerated type that describes the type of asynchronous event being reported.
HHP_FRAME_RATE
Enumerated type to select the image capture frame rate. Only valid when no auto exposure is
selected.
HHP_GAIN
Enumerated type to select the image capture gain. This type is only valid when no auto
exposure is selected.
HHP_PARITY Enumerated type for serial parity.
HHP_SEQ_MODES Enumerated type to specify the sequence acquisition mode.
HHP_STOP_BITS Enumerated type for number of serial stop bits.

Enumerates the function result codes returned by the SDK functions. See Error Codes on page
3-1.
SetupType_t
Enumerated type for specifying whether a read configuration item call should return the current
settings or the imager default setting.
