14. The transmission start delay is the amount of time between the point where the camera begins reading out the acquired image data from the sensor to the point where it begins transmitting the data for the acquired image from the buffer to the host PC Note that if the averaging feature is used the concept of the transmission start delay as described above does not apply In this case the acquired images are not transmitted individually but will be used for creating an averaged image which is transmitted The exposure start delay varies from camera model to camera model The table below shows the exposure start delay for each camera model Camera Model Exposure Start Delay piA640 210gm gc 12 44 us piA1000 48 gm gc 48 96 us piA1600 35 gm gc 35 59 us piA1900 32 gm gc 66 45 us piA2400 12gm gc 103 20 us piA2400 17 gm gc 75 43 us Table 11 Exposure Start Delays Basler pilot 95 Image Acguisition Control Note that if the debouncer feature is used the debouncer setting for the input line must be added to the exposure start delays shown in Table 11 to determine the total start delay For example assume that you are using an piA640 210 camera and that you have set the cameras for hardware triggering Also assume that you have selected input line 1 to accept the hardware trigger signal and that you have set the Line Debouncer Time Abs parameter for input line 1 to 5 us In this case Total Start Delay Sta

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 by packet n 1 In this case as soon as packet n 1 enters the receive window packet n will be detected as missing Basler pilot 29 Basler Network Drivers and Parameters General Parameters Enable Resend Enables the packet resend mechanisms If the Enable Resend parameter is set to false the resend mechanisms are disabled The performance driver will not check for missing packets and will not send resend requests to the camera If the Enable Resend parameter is set to true the resend mechanisms are enabled The performance driver will check for missing packets Depending on the parameter settings and the resend response the driver will send one or several resend requests to the camera Receive Window Size Sets the size of the receive window Threshold Resend Mechanism Parameters The threshold resend request mechanism is illustrated in Figure 14 where the following assumptions are made Packets

The main advantage of the performance driver is that it significantly lowers the CPU load needed to service the network traffic between the PC and the camera s 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

38. Basler pilot Features Using the Luminance Lookup Table to Get 8 Bit Output As mentioned above when the camera is set for a pixel format where it outputs 12 effective bits the lookup table is used to perform a 12 bit to 12 bit conversion But the lookup table can also be used in 12 bit to 8 bit fashion To use the table in 12 bit to 8 bit fashion you enter 12 bit values into the table and enable the table as you normally would But instead of setting the camera for a pixel format that results in 12 bit camera output you set the camera for a pixel format that results in 8 bit output such as Mono 8 or YUV 4 2 2 Packed In this situation the camera will first use the values in the table to do a 12 bit to 12 bit conversion It will then truncate the lowest 4 bits of the converted value and will report out the remaining 8 highest bits Changing the Values in the Luminance Lookup Table and Enabling the Table You can change the values in the luminance lookup table LUT and enable the use of the lookup table by doing the following Use the LUT Selector to select a lookup table Currently there is only one lookup table available i e the luminance lookup table described above Use the LUT Index parameter to select a value in the lookup table The LUT Index parameter selects the value in the table to change The index number for the first value in the table is 0 for the second value in the table is 1 for the third value in the table is 2

45. Specifications Reguirements and Precautions 1 Avoiding EMI and ESD Problems The cameras are frequently installed in industrial environments These environments often include devices that generate electromagnetic interference EMI and they are prone to electrostatic discharge ESD Excessive EMI and ESD can cause problems with your camera such as false triggering or can cause the camera to suddenly stop capturing images EMI and ESD can also have a negative impact on the quality of the image data transmitted by the camera To avoid problems with EMI and ESD you should follow these general guidelines Always use high quality shielded cables The use of high quality cables is one of the best defenses against EMI and ESD Try to use camera cables that are the correct length and try to run the camera cables and power cables parallel to each other Avoid coiling camera cables If the cables are too long use a meandering path rather then coiling the cables Avoid placing camera cables parallel to wires carrying high current switching voltages such as wires supplying stepper motors or electrical devices that employ switching technology Placing camera cables near to these types of devices may cause problems with the camera Attempt to connect all grounds to a single point e g use a single power outlet for the entire system and connect all grounds to the single outlet This will help to avoid large ground loops Large ground loops ca
