During the Data and Image export operation the sensor's output channels might become full. This can occur if the sensor is
producing export data (frames) faster than the data can be exported from the device (due to bandwidth limitations) or faster
than the client is reading the channel export data.

This setting affects how the sensor will behave in this situation.

• Select Hold READY to ensure that all frames are transmitted. In this case, the READY signal will remain inactive (sensor

is busy) until the new frame has been added to the channel for transmission. Triggers might be missed during this time.

• Select Do not hold READY to cause the sensor to discard the new frame if the channel is full and thus activate the

READY signal immediately after the current inspection is complete. In this case, the discarded frames will not be trans-
mitted.
