Touch the left-hand number to set the lower limit for "Warning". Touch the
right-hand number to set the lower limit for "Fail". The lower limit of "Fail"
must be equal to or greater than the lower limit of "Warning" (defining a
"Within limits" range in between them).
When you select the check box, you can enable various thresholds. Touch
the Setup button to display the Ethernet threshold setup dialog box.
In the dialog box, select the check boxes for the relevant thresholds and
then touch the Close button to list them on the Thresholds screen. You
can select/deselect all check boxes in the dialog box by using the Select all
/ Clear all buttons. Touch the individual value fields either in the dialog box
or in the list on the screen to specify the threshold values.
The Network Master transmits the 32-bit "jam sequence" eight times when the
Ethernet frames collide at any point in the frame. This collision motion is
different from the definition of the IEEE Standard.
In the "back off" process of the Network Master, the maximum wait time is
expanded up to the 12 power of 2. Moreover, the Network Master does not
discard the frame when the collision has occurred 16 times.
