3.2.2 Working with Tags
Single-axis Readers are tag orientation sensitive.
Reading and writing speeds depend on reader-tag communication speeds and
channel numbers (communication protocol), amount of information to be read
and/or written and number of tags presented at a time. The additional number
of tags and information to be read and especially written slow down read-write
communication. Please consult Sato Vicinity or your support organisation
regarding these issues for your specific application.
Please note that tags and Readers can be incompatible with each other.
Bigger tags can typically work with all types of Readers. Smaller tags require
higher field strengths to communicate with a Reader and as a result they
may not communicate with some Readers or have to be closer to a
Reader antenna to function. Please consult Sato Vicinity or your support
organisation regarding these issues for your specific application.
3.2.3 Installation Requirements
The MDR-3021AT is a stand-alone peripheral desktop device that does not require special
installation or tuning of an internal antenna.
Power supply requirements:
Mains input:
110 - 240 VAC @ 50/60 Hz
Low voltage input (MDR-3021AT):
12 VDC @ 2.5A
3.2.4 Tag to Reader Orientation
As the MDR-3021AT is a single axis reader the RFID tags should always be presented facing the
Reader surface to ensure optimum performance. Although the tags may still work at some angle
depending upon the distance between the tag and the Reader & the type of tag used this is not how
the MDR-3021AT reader was designed to work.
