It also has a more robust packet resend mechanism For more information about compatible Intel chipsets see the Installation and Setup Guide for Cameras Used with Basler s pylon API AW000611xx000 The performance driver uses two distinct resend mechanisms to trigger resend requests for missing packets The threshold resend mechanism The timeout resend mechanism The mechanisms are independent from each other and can be used separately However for maximum efficiency and for ensuring that resend requests will be sent for all missing packets we recommend using both resend mechanisms in a specific optimized combination as provided by the parameter default values The performance driver s parameter values determine how the resend mechanisms act and how they relate to each other You can set the parameter values by using the pylon Viewer or from within your application software by using the pylon API Note The parameter default values will provide for the following The threshold resend mechanism precedes the timeout resend mechanism This ensures that a resend request is sent for every missing packet even at very high rates of arriving packets The timeout resend mechanism will be effective for those missing packets that were not resent after the first resend request We strongly recommend using the default parameter settings Only users with the necessary expertise should change the default parameter values The Basle

Bandwidth Assigned parameter values and see if the sum is now less than 125 MByte s 5 2 1 A Procedure for Managing Bandwidth In theory managing bandwidth sharing among several cameras is as easy as adjusting the inter packet delay In practice it is a bit more complicated because you must consider several factors when managing bandwidth The procedure below outlines a structured approach to managing bandwidth for several cameras The objectives of the procedure are To optimize network performance To determine the bandwidth needed by each camera for image data transmission To determine the bandwidth actually assigned to each camera for image data transmission For each camera to make sure that the actual bandwidth assigned for image data transmission matches the bandwidth needed To make sure that the total bandwidth assigned to all cameras does not exceed the network s bandwidth capacity To make adjustments if the bandwidth capacity is exceeded Step 1 Improve the Network Performance If you use as recommended the Basler performance driver with an Intel PRO network adapter or a compatible network adapter the network parameters for the network adapter are automatically optimized and need not be changed If you use the Basler filter driver and have already set network parameters for your network adapter during the installation of the Basler pylon software continue with step two Otherwise open the Network Connection Pro
