Genie Color Series-GigE Vision Camera Operational Reference

73
GevSupportedOptionalCommandsConcatenation = Indicates if multiple operations in a single
message are supported. GevHeartbeatTimeout = Current heartbeat timeout in milliseconds.
GevTimestampTickFrequency = 64-bit value indicating the number of timestamp clock ticks in
1 second.
GevTimestampControlLatch = Latches the current timestamp value of the device.
GevTimestampControlReset = Resets the timestamp count of the device.
GevTimestampValue = Latched 64-bit value of the timestamp. Value must first be latched using
GevTimestampControlLatch.
GevStreamChannelSelector = Indicate which stream channel to configure.
GevSCPInterfaceIndex = Index of network interface.
GevSCPSPacketSize = The size of the stream packet to send on this channel.
GevSCPD = Delay (in 1µs) to insert between each packet for this stream channel.
Other networks parameters may be available through the 3rd party package used.
Sapera Supported Features List
The Genie features and its currently set values can be read by a Sapera application. The Sapera tool CamExpert is
an example of an application that reads and writes Genie parameters to control its operation. The following tables
group the Genie features by their feature type—STRING, ENUM, INT32, BOOL, and describe their possible values
and limits. Following the feature type tables, Genie features are also summarized as function groups, which allows
quick review of features associated with operational functions (such as trigger).
Accessing Features with + LT
When working with Genie features, the SapAcqDevice class provides functions for accessing features from devices
such as a GigE-Vision camera. The class also contains functions for sending commands and registering events to
devices.

SapAcqDevice::GetFeatureInfo returns information on a feature associated with a specified name or
index.

SapAcqDevice::SetFeatureValue writes a new value for a feature.

All information about the feature is stored in a SapFeature class object.
An important factor when reading or modifying Sapera features values is the feature Write Mode. Each Genie
feature description includes the access type and write mode as defined in the following table.
Access Type Write Mode
RO Read Only Invalid Write Not Valid
RW Read or Write Always Write Always (anytime)
Wo Write Only N.acq Write when transfer object Not Acquiring
N.conn Write when transfer object is Not Connected
Refer to the + LT Programmer's manual (OC-SAPM-SPPP0).
