Write Page
Use the
Write
page to replace the id or data that is
encoded on a tag.
Consider the following guidelines when writing to tags:
•
Always place a tag 0.3–0.6m (1–2ft) from the
antenna when writing data. The tag may be
damaged if it is too close to the antenna.
•
Only unlocked tags can be written.
•
The id or data to be written must match exactly
the number of hexadecimal characters (numerals
from 0-9 and letters from A-F) specified by the
tag’s protocol. For example: 64-bit EPC1 tag ids
are 16 hexadecimal characters long.
•
To write one tag, place the tag in the antenna field.
If multiple tags are present, they will all be
encoded with the same EPC data.
•
Use the antenna connected to port 1 of the reader
