Piranha ES-xx User Manual03-032-20070-02 Teledyne DALSA38Figure 13: Binning Start and End Values when using a Region of InterestIn this exam ple a region of interest is set to inclu d e pixels 4 to 9 and horizontal binning isset to 2. Becau se pixel 3 is now inclu d ed in the sam e d ata grou p as pixel 4, the re gion ofinterest w ill now inclu d e the d ata from pixel 3. Also, pixel 10 is inclu d ed in the sam e d atagrou p as pixel 9, so pixel 10 is now part of the region of interest. To see how the region ofinterest start and stop valu es have been rou nd ed , u se the com m and get roi.Setting Vertical BinningSyntax: Increases the vertical pixel pitch and light sensitivity by d ecreasingvertical resolution. Vertical binning is also useful for increasingframe rate in Area Mod e. Vertical binning in TDI Mod e shouldonly be used if your w eb’s shaft encod er provid es a red uced ratioof pulses to match w eb speed .Syntax: sbv iSyntax Elements: iVertical binning value. Available values are 1 (factory setting,no binning) to 4 (ES-82 mod el) or 1 to 8 (ES-80 model).N otes:  You w ill have to recalibrate the camera after changing binningvalues. Increasing the vertical binning, d ecreases the maximumallow able line rate. You may have to enter a new cameraframe rate after changing vertical binning values if the currentvalue becomes invalid . The camera send s a w arning messagein this situation.Example: sbv 23.3.5 Exposure Mode and Line/Frame RateHow to Set Exposure Mode and Line/Frame RateYou have a choice of operating the cam era in one of tw o exposu re m od es. Depend ing onyou r m od e of operation, the cam era’s line/ fram e rate (synchronization) can be generatedinternally throu gh the softw are com m and ssf or set externally w ith an EXSYN C signal(CC1). When operating in TDI Mod e, it is im portant that the line rate u sed m atches thew eb speed . Failu re to m atch the w eb speed w ill resu lt in sm earing.
