Line acquisition is automatically resumed when forward motion is resumed at the position where acquisition was interrupted.

– The rate converter enables the camera to acquire lines at any programmable resolution below or above the resolution of the motion encoder.

This provides designers with an amazing degree of freedom in the application development process.

This provides designers with amazing freedom and flexibility in the application development process.

and is implemented by splitting the encoder input signal using a programmable integer multiple.

input signal using a programmable integer multiplier.

When activated, this feature records metadata beside image data. Line metadata are captured every acquired image line.

Line-scan Metadata insertion

Buffer metadata are only captured when the first image line of a buffer is acquired.

The metadata are composed with a configurable set of general purpose event counters, quadrature encoder

The metadata are composed with a configurable set of general purpose event counters, quadrature encoder position counters and/or I/O line status.

This feature allows line-scan applications to correlate image data with system events including motion encoder positions.

Line Scan Trigger Capability

– The Coaxlink image acquisition card controls the camera scan rate based on signals received from the motion encoder.

If the part is moving faster, the camera’s acquisition line rate will increase.

If the part is moving slower, the camera’s acquisition line rate decreases.

– The Coaxlink board interprets the A/B signals from the Quadrature Motion Encoder to know in which direction (forward or backward) the part is moving.

– The Coaxlink card can also be commanded to acquire laser lines when the object is moving only forwards or only backwards.

– When a backward movement is detected, the function called ‘Backward movement cancellation’ stops the acquisition.

Area Scan Trigger Function

– Triggers are used to initiate acquisition when a part is in place. Hardware triggers come from Coaxlink’s I/O lines.

Software triggers are from the application.

– Controllable delay triggers to control the point at which image acquisition is delayed.

– Trigger extraction feature allows certain triggers to be skipped.

– Camera exposure control allows the application to control the exposure time of the camera.

– When the system starts to acquire images, the Coaxlink capture card generates a signal at

an appropriate point in time to control the lighting equipment connected to the output.

Line Scan Trigger Capability

Coaxlink supports both continuous roll scanning (to inspect infinite, continuously moving surfaces without losing lines)

and discrete target scanning (to capture images of targets moving in front of the camera).

(to capture images of targets moving in front of the camera).

– Triggers are used to initiate acquisition when the part is in position. 

Hardware triggers are from the motherboard I/O lines. Software triggers come from the application.

– Once initiated, the acquisition will continue indefinitely (for rolling the network):

– Continue indefinitely (for rolled-net monitoring applications)

– continue for a programmable number of lines (to acquire a target image of known length)

– continue until an end trigger signal is received (to acquire variable length target images)

– Controllable delay trigger to delay the start of acquisition by a programmable number of lines.

What are the benefits of using CoaXPress-over-Fiber for my application?

• Ultra-high data and frame rates

• Many accessory and cabling options to cover any length requirement

• Low CPU overhead, low latency, low jitter image acquisition

• Highest camera count per PC performance

• Very competitive cost/performance ratio

• Wide industry acceptance due to JIIA and IEEE standardization

What are the jitter and latency of CoaXPress-over-Fiber? How do they compare to “traditional” CoaXPress?

CoaXPress-over-Fiber is based on the CoaXPress protocol and it exhibits the same high performance as CoaXPress in terms of jitter and latency.

In addition, as CoaXPress-over-Fiber supports higher transmission speed compared to CoaXPress, the jitter and latency will be further improved in these versions.

What is the maximum cable length with multi-mode fibers?

With a standard 40GBASE-SR4 QSFP+ Optical Transceiver Module and an MTP/MPO multi-mode fiber cable, the maximum cable length is 150 meters.

This solution is suitable for machine vision applications.

What is the maximum cable length with single-mode fibers?

With a standard 40GBASE-ER4 QSFP+ LC DOM Optical Transceiver Module and an LC-Duplex single-mode fiber cable,

the maximum cable length is 40 kilometers. This solution is suitable, for example, for video transmission applications.

What are the pros and cons of using fiber optics?

Pros

• First and foremost, cable length is not an issue anymore as fiber connectivity is basically not limited in length.

• Fiber optics provide more bandwidth, as connectivity at 10 and 25 Gbps per fiber is standard today and widely used in data centers.

• Fiber optics are immune to electrical noise, which will be a significant advantage on the production floor and in some medical applications.

• Fiber optics are lighter and smaller in size than the equivalent copper cabling,

making it appropriate for applications where this characteristic is essential, like in aircrafts or vehicles.

Cons

• There is no “power over fiber”. As signals in fiber optics are transmitted using light,

there is no way to transfer power over fiber optics and devices such as cameras must be powered separately.

What are the cable options for CoaXPress-over-Fiber?

One of the most important benefits of CoaXPress-over-Fiber is the wide variety of connectivity options already available from multiple companies.

The initial connectivity options for CoaXPress-over-Fiber and the Coaxlink QSFP+ at 10 Gbps are SFP+ and QSFP+ (Quad, or four times SFP+) modules.

The advantage of using modules compared to fixed interfaces is that ports can be equipped

with any suitable type of transceiver as required by the application.
