Using the sot com m and , you d eterm ine thecam era’s ou tpu t rate. These tw o com m and s w ork together to d eterm ine you r final cam eraou tpu t configu ration.You can fu rther configu re you r read ou t u sing the smm com m and to select the cam era’spixel read ou t d irection.The follow ing tables su m m arize the possible cam era configu rations for each of the H S-xxcam era m od els. Refer to the figu re below for a d escription on how to select you r cam e raou tpu t.Figure 25: How to Read the Camera Link TablesCamera Link Mode Configuration (Controlled byclm command)Readout Direction(Controlled bysmm command)Pixel RateConfiguration(Controlled by sotcommand)Command Camera LinkConfigurationCamera Link Taps BitDepthsmm 0 increment =1smm 1 increment = -1clm 2 Base 2 Camera Link tapswhere:1 = CCD taps 1 +22 = CCD taps 3+48 smm 0 =CL tap 1 (1-2048)CL tap 2 (2049-4096)smm 1 = CL tap 1 (4096-2049)CL tap 2 (2048-1)sot 160 = 80 MHzstrobe(max line rate36kHz)sot 80 = 40 MHzstrobe(Max line rate18kHz)Find the rows in the tablewith a line rate greater thanor equal to your desiredline rate.From the rows determined in part A,find the values in the tablewith a throughput greater than or equalto your your required throughput.sotFrom the rows determined bypart B, find the Camera Link modeswith your desired bit depth.From the remaining rows determinedin part C, select an acceptable Camera Linkconfiguration. If none of the remainingconfigurations are acceptable for your system,you will have to reduce your bit depthor line rate.Set the pixel readout direction.Note: Horizontal binning reducesthe number of pixels sent to theframe grabber by the binning factor.Note: In the follow ing tables, a CCD tap refers to the actu al physical taps on the sensor ,w hile the Cam era Link taps refer to the w ay the d ata is configu red for ou tpu t overCam era Link.
