Stream Channel Destination Address; Heartbeat - FLIR GRASSHOPPER 3 Series Technical Reference

2.4.4.1 Stream Channel Destination Address

The stream channel destination address (SCDA) register is used to specify the streaming destination IP address.
The default SCDA is the IP address of the network or computer to which the camera is connected. It can be set
within a range so that the camera sends data as a multicast. As long as switches in the path between the sender
and receivers support and are configured for multicasting, multiple receivers can listen to the data stream from the
camera.
Multicast addresses are between 224.0.0.0 and 239.255.255.255.
To control SCDA use:
GenICam—GevSCDA in the
n

2.4.4.2 Heartbeat

The heartbeat is a mandatory GigE Vision feature to monitor the connection between an application and the
camera. The application must continually reset the heartbeat timer, or the camera assumes an error has occurred
and shut down the connection.
In general, the FlyCapture API manages the heartbeat at a low level; however the following two features are
controllable: Heartbeat Timeout and Heartbeat Disable.
Heartbeat Timeout
Heartbeat timeout is the time, in milliseconds, that the camera waits between resets from the application.
Heartbeat timeout can be set between 500 ms and 10 seconds. The default setting is 3000 ms (3 seconds). If
there is no communication between the camera and the application for longer than the timeout value, the
connection is shut down.
To control Heartbeat Timeout use:
GenICam—GevHeartbeatTimeout in the
n
FlyCapture API—The FlyCapture SDK supports configuring heartbeat timeout. For more information,
n
consult the FlyCapture SDK Help.
Heartbeat Disable
The heartbeat is enabled by default. Heartbeat disable allows the heartbeat function in the camera to be disabled.
To disable Heartbeat use:
GenICam—GevGVCPHeartbeatDisable in the
n
Registers.
FlyCapture API—The FlyCapture SDK supports configuring heartbeat timeout. For more information,
