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 Basler performance driver uses a receive window to check the status of packets The check for missing packets is made as packets enter the receive window If a packet arrives from higher in the sequence of packets than expected the preceding skipped packet or packets are detected as missing For example suppose packet n 1 has entered the receive window and is immediately followed
