Transport Layer Control Features and Nodes

Transport layer control features in high-speed cameras from Emergent Vision Technologies play a pivotal role in streamlining data handling processes. These features ensure efficient, reliable data transmissions and enhance diagnostic capabilities, crucial for maintaining system integrity and performance optimization.

The network and data transmission control and diagnostic features focus specifically on maximizing data transmission efficiency and reliability. This includes ensuring data integrity and facilitating comprehensive system diagnostics to prevent and quickly resolve issues. Timestamp and synchronization features are essential for coordinating precise timing across multiple devices or frames, integral in complex imaging tasks requiring synchronized data collection. Additionally, the SFP module diagnostic features provide critical real-time health and performance assessments of network links. These diagnostics monitor various parameters such as type, power levels, voltage, and temperature, which are vital for preemptive maintenance and efficient troubleshooting, thereby minimizing downtime and enhancing system reliability.

You can use the features with Emergent's eCapture Pro application. Alternatively, you can use the features with Emergent's eSDK API and the feature nodes. The \EVT\eSDK\Examples\EVT_TransportLayerControl directory contains example code that demonstrates how to programmatically use the transport layer control features.

Note: Each Emergent camera provides some or all of the following features and nodes, depending on the camera model.
