The default on cameras with asettable clock speed is 40 MHz.Setting the Camera Link Clock SpeedOn camera models with a settable clock speed, you can set the speed with the CameraConfiguration Tool Plus (CCT+) or by using binary write commands from within your own applicationto set the camera’s control and status registers (CSRs).With the CCT+With the CCT+ (see Section 7.1 on page 230), you use the Camera Link Clock parameter in theOutput Mode parameters group to set the clock speed.By Setting CSRsYou set the clock speed by writing a value to the Clock Speed field of the Camera Link Clock SpeedCSR (see page 239).See Section 7.2.2 on page 238 for an explanation of CSRs and Section 7.3.1 on page 282 for anexplanation of using read/write commands.Model Camera Link Clock SpeedspL2048-39kc 40 or 80 MHzspL2048-70kc 40 MHzspL4096-39kc 40 or 80 MHzspL4096-70kc 40 or 80 MHzspL8192-39kc 40 or 80 MHzTable 8: Camera Link Clock Speed(s)
