Encoder Timeout

In line scan cameras, the encoder timeout feature sets how long the internal logic should wait before considering the current frame aborted due to absent or slow encoder pulses.

The timeout value is measured in cycles of the camera’s timestamp clock, not in microseconds. The frequency of this clock is defined by the GEV Timestamp Tick Frequency, which varies by camera model. For example:

• 10GigE cameras use a frequency of 150,000,000 Hz (150 MHz)
• 25GigE and 100GigE cameras use a frequency of 400,000,000 Hz (400 MHz)

To convert a timeout value to seconds, divide it by the current GEV Timestamp Tick Frequency. For instance, a timeout value of 600,000 corresponds to 4 ms on a 150 MHz clock.

Note: This feature's value limits can be influenced by other features, such as line time, so recheck the values after adjusting related features.

GP_ENC_TIMEOUT node

• Access mode: Read/Write
• Node type: Uint32

You can use the eSDK API functions to:

• get and set the node’s current value, and
• get the node’s minimum and maximum values, and the node’s value increments.
