Convertors speed analogue video over IP
The iPort PT1000 ANL-2/12 and ANL-2/6 analogue video IP engines are billed as the industry's first analogue-to-IP convertors for applications requiring machine vision-grade performance.
Communications software speeds video transmission
A novel high-speed PC communications software package aims to slash the cost, enhance the performance and increase the flexibility of vision systems with large processing overheads.
The PT2000-CLM is designed for high-bandwidth vision applications that send imaging data to PCs for immediate processing, such as postal sorting systems and the high-speed inspection systems used by manufacturers of flat panel displays and semiconductor wafers.
Pleora's CLM engine converts imaging data from medium-rate CameraLink cameras into IP packets and sends it to PCs at rates of up to 200Mbyte/s over two ordinary GigE copper cable links.
The engine supports traditional point-to-point connections between cameras and PCs, as well as high-speed, packet-switched GigE vision networks interconnecting one or more cameras to one or more PCs.

More flexibility for video transmission
Pleora Technologies has made key enhancements to its iPort Vision Connectivity Solution that allow designers to substantially improve the performance and flexibility of GigE-based imaging systems.
In all configurations, the PT2000-CLM delivers the low, predictable end-to-end latency (or delay) and instantaneous triggering required by advanced, real-time image processing systems.
"The PT2000-CLM meets growing customer demand for high-bandwidth camera-to-PC connections that leverage the economy, ease of use, and flexibility of commercial GigE equipment", said Alain Rivard, Vice-President of Engineering, Pleora Technologies.
"The engine drives cost and complexity from medium-rate CameraLink installations by eliminating or reducing the need for specialised PC hardware like frame grabbers and DSP boards".
Pleora's iPort PT2000-CLM is compatible with most medium-rate CameraLink models, including the industry-dominant 160MHz, four-tap configuration.
The engine can reconstruct images from camera pixel taps prior to GigE transport, reducing the CPU processing load when data arrive at the PC.
The CLM engine offers flexible real-time triggering via Boolean combinations and camera control signals.
These are delivered through a fully featured GPIO (general purpose input/output) interface with two TTL inputs and outputs, one LVDS input, an optically isolated input and output, multiple programmable timers and rescalers, and a signal delayer with a 32-event queue.
The PT2000-CLM allows vision system designers to build flexible, high-bandwidth vision applications using economical, widely available, commercial GigE switches and PC NICs.
With the CLM engine, designers can, for instance, build systems with multiple cameras, multicast data from cameras to multiple PCs, or distribute image processing functions across multiple PCs.
Separate PC frame grabbers and DSP cards are not required.
As part of Pleora's iPort Vision Connectivity Solution, the PT2000-CLM is delivered with powerful PC software: two iPort IP device drivers, one for each GigE link, and the iPort software development kit (SDK).
The drivers, which run on standard NICs, stream incoming video data into PC memory using only 1% of CPU capacity.
This leaves ample power available for the simultaneous processing of vision applications.
The SDK is an advanced user interface that eases applications development.
