  • Long Cable lengths up to 100 meters using standardized connections.
  • One cable solution can provide digital video, power, trigger and GPIO
  • Cost effective cable solutions which are hot pluggable.  
  • Real time behavior with fixed, very low latency transmission.  
  • Potential to re-use existing coaxial cable to upgrade image systems.  

CoaXPress is an interface which requires a frame grabber on the host computer which communicates with the camera.  

Teledyne Dalsa has recently adopted CoaXPress into the popular Xtium family of frame grabbers providing a robust solution based on the current Xtium platform.  

The Xtium-CXP PX8 is based on the industry standard PCI Express Gen 2.0 expansion bus to deliver high speed access to host memory over 8 lanes.  Featuring a half length PCIe card with 4 input channels of up to 6.25 Gb/s, fully supported by Dalsa's Sapera LT SDK.



What is the key differentiator of the Xtium-CXP PX8 CoaXPress frame grabber?  

Free Run Time licences
When using Teledyne Dalsa's Sapera processing library, the Xtium series offers free run-time licenses for Sapera processing standard Run-Time (RTL).  The standard tools include access to over 350 highly optimized image processing functions and tools for area based search, blob analysis and image calibration!  If you are already using Sapera processing, you have an immediate cost savings!

Trigger to Image Reliability framework
The Xtium series support Sapera LT’s Trigger-to-Image (T2IR) framework for maximum reliability of the image acquisition system. The T2IR functions provide critical, real-time details of system events that help track and monitor acquisition, transfer, and control processes to ensure reliability of the imaging system.  System up-time is increased and cost are lowered and all free of charge as part of the Sapera LT SDK.

How do you get the most pixels for your money? Check out the new Dalsa Nano C4900 camera!


Teledyne Dalsa has continued expanding its Genie Nano GigE vision camera series. Introducing the Nano C4900 GigE camera based on the ON Semiconductor AR1820HS 18 Megapixel Back Side Illuminated (BSI) image sensor with a resolution of 4912 x 3684.

Attractively priced below $600, this just may be the most pixels for your money!

Furthermore, Teledyne DALSA’s “Burst Acquisition” feature provides frame rates of 13 fps @ 18MP pixels resolution while maintaining superb image quality!





 

If the attractive price for 18 MP is not enough to get you excited, there are a few other aspects of this camera worth discussing further.  

 

  • Back Side Illuminated Technology (BSI):  If we were to look at this sensor 5 years ago and see a pixel size of 1.25um, we’d assume that is not light sensitive.  On the contrary as ON Semiconductor flipped the pixel upside down!  Traditional image sensors were front illuminated where the photo detectors were towards the back of the pixel stack.  In turn, there was loss in this method as it interfered with overall light reaching the detector.  Back side illuminated sensors have the same elements, but the photo detector was moved forward to not have as much loss due to internal wiring and reflections.  BSI technology improves the change of photons being captured from 60 to 90% on average providing high sensitivity even in small pixels!
  • Burst Acquisition mode:  The Nano C4900 has 200 MB of internal memory allowing image capture at higher rates exceeding the GigE bandwidth for periods of time.  This mode is very useful for applications needing a rapid series of images at intervals.  
  • Rolling Shutter with Global Reset:  Rolling shutter image sensors have the benefit of lower cost typically, but are limited to stationary objects due to image distortion. However, thanks to a the global reset feature, distortion is minimized by allowing all the lines to be exposed with read out of the lines there after.  
  • Extended Operating Temperature range:  Nano cameras have an operating case range of -20 to 60 deg. C.  This provides higher temperatures versus the competition. 
  • 1 / 2.3″ Image Format: High resolution cameras typically have relatively large formats which increases the cost of lenses.  As the pixels are relatively small, the image format is only 1/2.3 allowing lower cost lenses to be used.  


18 Megapixels, 13 frame/sec, high sensitivity, overall low cost creates possibilities!  

Applications may include: 

  • Low light, high magnification medical applicications
  • Industrial Metrology
  • Intelligent traffic solutions (ITS)
  • Microscope applications
  • Unmanned Aerial

Need high resolution, global shutter cameras still in a compact format?   Dalsa is now shipping the following new high resolution cameras: 

Dalsa Nano M4020 (IMX304) – 12MP,  4112 x 3008, 20 fps

Dalsa Nano M4030 (IMX267) – 9MP, 4112 x 2176, 30 fps

Can I just get my camera cables from the internet (or why do your cables cost so much!)

As distributors of camera systems, we hear this question many times a day. Why does your GigEor USB3 cable cost so much?  I can just buy a cable online from Amazon, Ebay, etc for $5 when yours cost $25 or more!
The answer is: You can..  sometimes… but it depends upon many things, and how critical those things are to your application. 
 
Here are 5 key variables you need to consider in a camera cable selection
  1. Distance from camera to computer
  2. Data rate in which the camera is transmitting  
  3. Importance of reliability of application 
  4. Structural integrity of connection at camera and computer
  5. Total cost of your process and / or down time

From many years of diagnosing industrial imaging problems, after incorrect software setup, BAD CABLES ARE NEXT ON THE LIST FOR  “MY CAMERA DOESN’T WORK” problems!!

Distance, the killing factor!  If you were to look at a ‘bode plot’ of the signal transmitting from the camera to the computer you would see dramatic attenuation of the signal vs. distance, and also versus the data rate. In fact, at the distance limits, you might wonder if it actually works as the signal is so low! 
GigE is rated at 100 meters, however, the signal does degrade quite a bit, so cable quality and data rate will be the determining factors.  USB3 does not have a real specification and it is difficult to find consumer grade cables greater than 2 meters in length. In fact, we have experienced poor results with consumer cables greater than 1 meter in length!
 
 
 
What are the differences between ‘Industrial’ and ‘’consumer’ cables?  
8 differences are listed below: 
  1. Industrial cables are tested to a specification for each cable.  There are no batch to batch differences. 
  2. That specification usually meets organization requirements such as IEEE or Automated Imaging Association (AIA) standards
  3. Industrial cables give you consistency from a single manufacturer (when buying online, you are not always sure you are getting the same cable)
  4. Industrial cables have over-molded connectors
  5. Industrial cables have screw locks on the ends
  6. Industrial cables are usually made with larger gauge wire
  7. Industrial cables typically specify bend radius
  8. Industrial cables are made with flex requirements (bend cycles they can meet)
When should we consider using an “Industrial cable”?  Here are a few examples to consider:
Example 1: In a research lab, using a microscope 1 meter from the computer running low data rates, non automated.
Distance is small, data rate is low, chance of someone pulling on the cable is low, and if the data doesn’t get delivered, you can re-acquire the image. There is no big need for a special cable and can buy it off the internet.
 
Example 1a:Let’s change some of these parameters, now assuming you are not in lab, but the microscope is in an OEM instrument being shipped all over the world
If the system fails because you went with an unspecified cable, what is the cost of sending someone to fix this system 3000 miles away? In this situation, even though the distance is small, and the data rate is low, the consequences of a cable failure are very high!
 
Example 2: GigE cameras running at close to the full bandwidth. If you don’t need screw lock connectors, and the distance is not too great (< 10 or 20 meters), 
You can probably get by with ‘higher quality’ consumer cables. At distances greater than 20 meters, if you care about system reliability, you will definitely want industrial cables.  
Example 3. Two to Four GigE cameras running at close to full bandwidth in a system.
 
If you need system repeatability, or anything close to determinism, you will need industrial cables. On the other hand, if you your application is not sensitive to packet re-sends, a consumer cable should work at under 20 meters
 
 
Example 4. GigE cameras in an instrument.  Regular GigE cables are just locked into the RJ45 with a plastic tab. 
 
If your product is being shipped, you can’t rely on this not to break. You want an industrial cable with screw locks.
 
Example 5. GigE cameras in a lab. 
 
Save the money and use a consumer cable!
 
Conclusions
  • If you running USB3 cables at distances more than 2 meters, DO NOT use consumer cables.  
  • If you are running multiple cameras at high speeds, DO NOT use consumer cables.  
  • Obviously, if you need to make sure your cables stay connected, and need lock downs on the connectors, you cannot use consumer cables. 
  • If you are running low speed , short distance, and you can afford to re-transmit your data, consumer cables might be just fine.
