The write/read area for transponders is located on the end face as well as on the top and
bottom of the front section of the enclosure.
The antenna of the RF680M is linearly polarized. For successful reading and writing, the
dipoles of the transponders and the antennas of the RF680M must be in parallel. Note the
technical data of the individual transponders.
The following figure shows the positioning of transponders in front of the antenna. The
maximum working range is achieved above and below the read head.
