4 Connecting the Camera
4.1 USB Vision Overview
Ratified in 2013, the USB Vision standard is a popular interface for industrial cameras connected to
computer systems. Teledyne Lumenera USB 3 cameras comply with the standard as defined by the
USB3 Vision Technical Committee of the Automated Imaging Association (www.visiononline.org).
The AIA USB3 Vision implementation uses the programming interface (API) previously defined by
the GenICam™ standard for access and control features in compliant imaging products, which
simplifies applications design and integration (device discovery, device control, event handling,
data streaming, etc.) for camera and system manufacturers.
For viability in real world machine vision environments, the standard also specifies locking USB 3
compliant connectors such as the USB 3.0 Standard-B and USB 3.0 Powered-B connector.
See Switching a Lumenera camera from LuCam mode to USB3 Vision mode to use cameras
with the Sapera LT development environment.
4.2 Connecting Power
Lt-Ux0x-xxxxx and Lt-Ux1x-xxxxx USB 3 cameras may be powered directly by the USB 3
computer port. This method provides a cabling solution for testing or for imaging installations
where camera acquisitions are only software controlled and require no external I/O.
Lt-Ux2x-xxxxx XL series cameras must be powered through the external interface
header. The external interface header also provides access for hardware input and output signals.
See section I/O Connector Pinout Details for the I/O connector and power supply specifications.
When the camera receives power, the status LED will indicate that the camera has initialized and is
ready:
• Lt-Ux0x-xxxxx and Lt-Ux1x-xxxxx: steady green
•
Lt-Ux2x-xxxxx: steady blue
4.2.1 Connectors
Depending on model, the camera has two or three connectors:
•
USB 3 – USB 3 connection to a computer
•
Lt-Ux0x-xxxxx and Lt-Ux1x-xxxxx: data and power
• Lt-Ux2x-xxxxx: data only
•
External Interface Header – Used for external signal connections and for camera power
• Lt-Ux0x-xxxxx and Lt-Ux1x-xxxxx: optional power
• Lt-Ux2x-xxxxx: required power
