rel=\"noopener\">CoaXPress<\/a> in machine vision inspection and metrology systems is partially due to the higher video data rates enabled.\u00a0 But in multi-camera systems, the smaller more flexible cables are an advantage to fit in tight spaces and enable moving heads.<\/p>\n<p><!--more--><\/p>\n<p style=\"padding-left: 300px;\"><a

rel=\"noopener\">CoaXPress<\/a> imaging systems, the cable selection can be relatively simple.\u00a0 For others where a very long cable length is required, or there is a constantly moving imaging head (as common with <a href=\"https:\/\/www.adimec.com\/Free-ePaper-CoaXPress-for-Multiple-Camera-Systems\" target=\"_blank\" rel=\"noopener\">multi-camera systems<\/a>, such as with <a href=\"https:\/\/www.adimec.com\/Machine-Vision-Camera-Requirements-for-3D-AOI\" target=\"_blank\" rel=\"noopener\">AOI<\/a>), cable selection is more challenging.<\/p>\n<p>So the first step with cable selection is to consider these 3 requirements:<\/p>\n<ul>\n<li>The speed configuration<\/li>\n<li>Cable length<\/li>\n<li>Cable flexibility<\/li>\n<\/ul>\n<p>&nbsp;<\/p>\n<p><strong>Frame speed over cables:<\/strong><\/p>\n<p>For details on the different frame speeds or bit rates over CoaXPress cables:<\/p>\n<p><a

Machine Vision Requirements<\/a><\/p>\n<p>&nbsp;<\/p>\n<p><strong>Cable Length:<\/strong><\/p>\n<p>One of the advantages of CoaXPress over other interface standards such as Camera Link and USB 3.0, longer cable lengths (i.e. 7 meters) can be used without repeaters which effect signal integrity.\u00a0 For most machine vision systems, longer lengths are not required.<\/p>\n<p><a

Flexibility:<\/strong><\/p>\n<p>What is of more concern is the flexibility of the cables required.\u00a0 If the wrong cable is selected, there could be failures.\u00a0 One problem is that there is no standard definition of high flex cables.<\/p>\n<p>&nbsp;<\/p>\n<p>The cable supplier can provide data\/reference numbers on the following:<\/p>\n<ol>\n<li>Flex test<\/li>\n<li>Twisting test<\/li>\n<li>U-shape bending test<\/li>\n<li>Moved bending test<\/li>\n<li>Cable bear bending test<\/li>\n<\/ol>\n<p>&nbsp;<\/p>\n<p>If a highly durable, high flex cable is required, we recommend acquiring some samples and testing them under the system conditions.\u00a0 Within the CoaXPress protocol, there is a link test to check the data between the camera and frame grabber for errors.\u00a0 This is called the Bit Error Rate Testing and can help you verify the cable selection.<\/p>\n<p>&nbsp;<\/p>\n<p>Contact us with any questions or for a free application note on using the Bit Error Rate Testing with the Euresys CoaXlink frame grabbers.<\/p>\n<p>&nbsp;<\/p>\n<p>Related Posts:<\/p>\n<p><a
