5-2 Obtaining angular degrees of a tilted barcode
Angular degrees when a workpiece is read from the front are obtained.
* If it is read from angles other than the front, correct angular degrees cannot be
obtained.
* Set the "partition mark" for SR to ":" (colon).

6 Editing read image file names
6-1 Appending read data to the read image file name
* The read data is specified as the image file name. If a code with exactly the same
data contents is read, the same image file name is adopted. In this case, the old
file is overwritten.
6-2 Appending date and time to the read image file name
* When setting the time on the SR-D100 Series, synchronize the time when setting
with the AutoID Network Navigator.
* When setting the time on the SR-1000/750 Series, prepare the SNTP server on
the same network and enable the synchronization with the SNTP.
6-3 Appending date and time and read data to the read image file name
* When setting the time on the SR-D100 Series, synchronize the time when setting
with the AutoID Network Navigator.
* When setting the time on the SR-1000/750 Series, prepare the SNTP server on
the same network and enable the synchronization with the SNTP.
