The Mantis™ II System by RF Code is an RFID monitoring system
designed to report Tags within defined Reader operating ranges. The system
utilizes “beacon” Tags that periodically report their presence with an encoded
radio transmission. The Mantis™ II Reader is a dual-channel radio receiver
tuned to the Mantis™ Tag transmission frequency of 303.825 MHz.
This manual provides the instructions for the Mantis™ II Reader setup and
operation. This Reader has different modes of operation and optional
functions that are user-selected depending on the system’s operational
requirements.
The instructions in this manual show how to install, configure, and upgrade
the Mantis™ II Reader as well as tips on Mantis™ Tag placement and
antenna optimization. Operational instructions for the Mantis™ II System
using the TAVIS™ Concentrator software by RF Code are found in the
The Mantis™ II Reader is housed in a 5 x 5 x 1.5 inch (12.7 x 12.7 x 3.81
cm) metal chassis and contains the internal components of a RFID Reader
combined with connections to allow for both Ethernet and serial port
connectivity.
Front View – LED Indicators
Figure 2.1 – Mantis™ II Reader (front view)
shown with standard ¼-wave helical antennas.
Three LEDs are mounted on the front of the Mantis™ II Reader.
•Unlabeled LED – This LED is used for a feature that is not
implemented in this version of the Reader.
•On-Ready LED – This LED indicates that the Reader has power
applied through an external power adapter.
•Tag Activity LED – This LED is used for two purposes: (1) to show
the status of the Reader while in standby mode and (2) to show Tag
detections while in operation.
•While Operating – The Tag Activity LED flashes intermittently,
indicating the Reader has read one or more Tags each time it flashes.
Because the Reader can decode Tags faster than the light can be
turned on and off, a single flash may indicate more than one Tag
being decoded.
•While in Standby Mode – The Tag Activity LED turns on and off at a
distinctive rate that indicates the Reader is in standby mode.
Rear View – Data Connections
Figure 2.2 – Mantis™ II Reader (rear view) showing connections for
Network/Ethernet (RJ-45), Power, and Serial/COM (RS-232).
Several connections are housed on the back of the Mantis™ II Reader.
•Ethernet – RJ-45 Ethernet jack. The Ethernet connection has a link-
state “LINK” LED and collision “COL” LED such as those found on
common Ethernet network connections. The LINK light stays solid
when there is no network activity and flashes when activity is present.
•Power – A plug allows for connection to both AC and DC power
sources. Power requirements are 12 to 28 VDC and 9 to 20 VAC.
Figure 2.3 – Standard ¼-wave helical antennas shown in various positions.
Each antenna post supplies an RF signal to the two parallel radio receivers in
the Mantis™ II Reader. Antenna input impedance is 50 ohms nominal.
Both the type of antennas used and the Reader range setting determine the
effective read range. The normal Reader-range features are defined using
¼-wave helical antennas.
These antennas are appropriate for most Reader applications. Optional
antennas that offer diverse receiving properties or extend the range of the
Reader are available for the Mantis™ II Reader. Contact your Mantis™ II
Reader distributor for more information.
The Mantis™ II Reader has two receiver channels that can operate
independently or jointly to provide Tag signal diversity reception. The Reader
can operate with one antenna on either antenna post, but the benefit of
receiver diversity reception is obtained with both antennas attached.
Depending on the location and orientation of the Tags, the signal path from
each Tag to the Reader may vary. Consequently, this may allow only one
antenna to receive the signal.
To achieve the best receiver diversity:
•Antenna Angle from Reader – It is desirable to have the antennas
positioned at different angles from the Reader.
•Antenna Angle from Each Other – Antennas should be at 90-
degree angles relative to each other. It may be necessary to
experiment with antenna positions to achieve optimum coverage.
•Height – As a rule, the higher a Reader is positioned above the
ground or floor, the better the Reader’s detection range.
WARNING – Do not allow antennas to overlap. Keep the antennas

separated. Allowing the antennas to overlap reduces the
effectiveness of each antenna.
•Separation – Maintain a 4-to-6-foot separation between the Reader
antennas and potential RF radiators such as computers, monitors,
printers and electronic office equipment. The local radio environment
can limit the Reader’s effective range.
•Height – Do not operate the Reader on or close to the floor or
ground. Grounded and reflective metallic structures around the
Reader and/or Tags affect the system performance. For best results,
the Reader should be mounted as high as reasonably possible.
WARNING – Readers should not be positioned close to ceilings as
they act as ground planes.
TOOLS – Low loss SMA coaxial extension cables may be used to
separate the antennas from the Reader.
NOTE – Optional antennas that offer diverse receiving properties or
extend the range of the Reader are available for the Mantis™ II
Reader. Contact your Mantis™ II Reader distributor.

Environmental Limits
The Mantis™ II Reader is approved for use within the temperature ranges
set forth below.
• Operation: -20 to +70 degrees Celsius.
• Storage: -40 to +80 degrees Celsius.
Tag Positioning
Wherever possible, Mantis™ Tags should be placed in the same orientation
(plane) in order to optimize the Reader’s ability to receive t r ansmissions
from the Tag. The Tags should not be placed closer than ½ inch in proximity
to one another.

File System
All embedded operating systems, signal processing software, and
configuration options of the Mantis™ II Reader are stored in a flash-based
file system internal to the Reader. If any changes or updates are required,
the files are collected in a directory on the PC, packaged into a new file
system, and then transferred to the Reader by TFTP (Trivial File Transfer
Protocol).
Upgradeable Firmware
The Mantis™ II Reader has the ability to be updated as new firmware is
released. It is vital that these updates be obtained directly from RF Code or
its authorized source, since these files define the operation of the Reader and
if defective, the files will render the Reader inoperable.
U
NOTE – The Mantis™ II Reader can only be configured through an
Ethernet connection via the RJ-45 jack on the rear of the Reader.
WARNING – When an Ethernet connection is made directly between
the Reader and a PC, a cross-over network cable is required.
WARNING – Firmware updates should be obtained directly from RF
Code or its authorized source. If defective, these files will render the
Mantis™ II Reader inoperable.
