the outgoing host message if nothing is received from the scale.

trailing edge of the box is the reference point. Trailing is the normal setting for a
message from scale.

to Trigger Line, enter the measured distance from the trigger to
the expected scale transmission location on the conveyor belt. This distance will
have been set up in the scale configuration. This parameter specifies the distance
from the Trigger Line (Trigger Source) to the expected receiving point of the Proto-
col Index. It is used together with the Minimum Distance betw
een Two Consecu-
tive Parcels parameter to assign the Protocol Index information to the correct
pack.
12. Select Upstre
am or Downstream from the Distance to Trigger Line State.
13. Enter a distance in the Min Distance be
tween Two Consecutive Objects text field.
This specifies the minimum distance (in mm) between two consecutive packages.
It is used to compensate for imprecision in the Distance from Protocol Index to
Trigger Line parameter by virtually lengthening the package.
