•
Set the unit numbers for each of the V530-R150s.
(In this example, the unit numbers are set to 00, 01, and 02.)
•
After the V530-R150 reads a code, it holds the data without
outputting it. Polling commands are sent out in order from the
host and the data is downloaded.
Note If a reading trigger is turned ON before the data is downloaded,
the V530-R150 will operate as shown below and the previous
reading data will be overwritten.
