Example 8. Active upload
Application: Suited for the logistics industry to measure the information about the exterior of a passing
object. The overall area and placement of an object can be calculated based on the fixed scan cycle and
scan result of each cycle. The overall volume can be calculated from the two groups of products. It can also
be used for correction applications in the printing and textile industries.
Description of automatic upload operation procedure:
1. After product is set in measurement mode, power is turned off and then turned on again. After
success, it will flash once every 2 seconds. (Product only needs to be set once.)

0).

Description of setting automatic scan cycle:
Scan cycle = beam scan time + data upload time + delay time 1 + delay time 2.
For beam scan time, refer to Table 4-1.
Data upload time depends on total bytes of uploaded data and communication format. Refer to
Table 4-2 and Table 4-3.
Delay time 1: Unit is 0.1msec multiplied by set value.
Delay time 2: Unit is 1msec multiplied by set value.
