Camera Performance and Features  

Measuring Line Rate (Trigger) 

See Camera Control Category in Appendix A for GenICam features associated with this section and 

how to use them. 

 

Related Feature: Measured Line Rate  

 

The Measured Line Rate command is used to read the line (trigger) rate being applied, externally 

or internally, to the camera. 

Maximum Line Rate 

The maximum line rate that the camera can achieve is determined by the number of CLHS lanes 

used and by the number of cables installed, as shown in the following table: 

 

Maximum Line Rate (1 sensor line output, 8 bit)

143 kHz 

NA 

ML-HM-16K30H-00-R 

NA 

NA 

300 kHz 

Minimum Line Rate 

The minimum line rate for all camera models is 0 kHz. Cameras go to full stop without image 

anomaly. 

Scan Direction  

See the section Camera Control Category in Appendix A for GenICam features associated with this 

section and how to use them 

 

Related Feature: sensorScanDirectionSource, sensorScanDirection 

 

A multiline camera requires the user to tell the camera the direction of travel of the object being 

imaged. 

 

The scan direction is set using the sensorScanDirectionSource command. The options are: Internal, 

Line 2 (pin 6 on the GPIO connector), and the rotary encoder feature (using pin 5 and pin 6 of the 

GPIO connector). 

 

When set to internal, use the sensorScanDirection feature to set the direction.
