Overview
Xtium2-CLHS PX8 User's Manual
DTE: Intelligent Data Transfer Engine
The Xtium2-CLHS PX8 intelligent Data Transfer Engine ensures fast image data transfers between
the board and the host computer with zero CPU usage. The DTE provides a high degree of data
integrity during continuous image acquisition in a non-real time operating system like Windows.
DTE consists of intelligent DMA units with auto-loading Scatter-Gather tables.
PCI Express x8 Gen3 Interface
The Xtium2-CLHS PX8 is a universal PCI Express x8 Gen3 board, compliant with the PCI Express
3.0 specification. The Xtium2-CLHS PX8 board achieves transfer rates up to 7.0Gbytes/sec. to host
memory. Note that performance can be lower depending on PC and/or programmed configuration.
The Xtium2-CLHS PX8 board occupies one PCI Express x8 Gen3 expansion slot and one chassis
opening.
Important:
•
To obtain the maximum transfer rate to host memory, make sure the Xtium2-CLHS PX8 is in a
computer with a Gen3 slot. The board will work in a Gen1, Gen2 or Gen3 slot, but only with a
quarter or half the possible transfer performance respectively.
•
The system motherboard BIOS should allow setting the PCIe maximum payload size to 256 or
higher. Systems with fixed settings of 128 will limit performance for transfers to host memory.
•
If the computer only has a PCI Express x16 slot, test directly (use the supplied
or review the computer documentation to know if the Xtium2-CLHS PX8 is supported. Computer
motherboards may only support x16 graphic video board products in x16 slots.
Advanced Controls Overview
Visual Indicators
Xtium2-CLHS PX8 features 3 LED indicators to facilitate system installation and setup
Status LEDs Functional Descriptions
). These indicators provide visual feedback on the board
status and camera status.
External Event Synchronization
Trigger inputs and strobe signals precisely synchronize image captures with external events.
Camera Link HS Communication Port
A single Sapera LT Acquisition Device provides access to the Camera Link HS camera configuration
via the board device driver. The communication port presents a seamless interface to access
GenICam camera features.
Quadrature Shaft Encoder
An important feature for web scanning applications, the Quadrature Shaft Encoder inputs allow
synchronized line captures from external web encoders (see
). The Xtium2-CLHS
PX8 provides a RS-422 input that supports a tick rate of up to 5 MHz.
