WARNING!
Operation of the M6e module requires professional installation to
correctly set the TX power for the RF cable and antenna selected.
EMC FCC 47 CFR, Part 15
Industrie Canada RSS-210
Federal Communication Commission Interference Statement
This equipment has been tested and found to comply with the limits for a Class B
digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to
provide reasonable protection against harmful interference in a residential installation.
This equipment generates uses and can radiate radio frequency energy and, if not
installed and used in accordance with the instructions, may cause harmful interference to
radio communications. However, there is no guarantee that interference will not occur in a
particular installation. If this equipment does cause harmful interference to radio or
television reception, which can be determined by turning the equipment off and on, the
user is encouraged to try to correct the interference by one of the following measures:
 Reorient or relocate the receiving antenna.
 Increase the separation between the equipment and receiver.
 Connect the equipment into an outlet on a circuit different from that to which the
receiver is connected.
 Consult the dealer or an experienced radio/TV technician for help.
This device complies with Part 15 of the FCC Rules. Operation is subject to the following
two conditions: (1) This device may not cause harmful interference, and (2) this device
must accept any interference received, including interference that may cause undesired
operation.
FCC Caution: Any changes or modifications not expressly approved by the party
responsible for compliance could void the user's authority to operate this equipment.
This transmitter module is authorized to be used in other devices only by OEM
integrators under the following conditions:
1. The antenna(s) must be installed such that a minimum separation distance of 25cm is
maintained between the radiator (antenna) & user’s/nearby people’s body at all
times.

Communication Regulation Information
10
2. The transmitter module must not be co-located with any other antenna or transmitter.
As long as the two conditions above are met, further transmitter testing will not be
required. However, the OEM integrator is still responsible for testing their end-product for
any additional compliance requirements required with this module installed (for example,
digital device emissions, PC peripheral requirements, etc.).
Note
In the event that these conditions can not be met (for certain configurations
or co-location with another transmitter), then the FCC authorization is no
longer considered valid and the FCC ID can not be used on the final product.
In these circumstances, the OEM integrator will be responsible for re-
evaluating the end product (including the transmitter) and obtaining a
separate FCC authorization.
The OEM integrator has to be aware not to provide information to the end user regarding
how to install or remove this RF module in the user manual of the end product.
User Manual Requirement
The user manual for the end product must include the following information in a
prominent location;
“To comply with FCC’s RF radiation exposure requirements, the antenna(s) used for this
transmitter must be installed such that a minimum separation distance of 25cm is
maintained between the radiator (antenna) & user’s/nearby people’s body at all times and
must not be co-located or operating in conjunction with any other antenna or transmitter.”
AND
“The transmitting portion of this device carries with it the following two warnings:
“This device complies with Part 15....”
AND
“Any changes or modifications to the transmitting module not expressly approved by
ThingMagic Inc. could void the user’s authority to operate this equipment” “

Industry Canada
Under Industry Canada regulations, this radio transmitter may only operate using an
antenna of a type and maximum (or lesser) gain approved for the transmitter by Industry
Canada. To reduce potential radio interference to other users, the antenna type and its
gain should be so chosen that the equivalent isotropically radiated power (e.i.r.p.) is not
more than that necessary for successful communication.
This radio transmitter (identify the device by certification number, or model number if
Category II) has been approved by Industry Canada to operate with the antenna types
listed below with the maximum permissible gain and required antenna impedance for
each antenna type indicated. Antenna types not included in this list, having a gain greater
than the maximum gain indicated for that type, are strictly prohibited for use with this
device
Operation is subject to the following two conditions: (1) this device may not cause
interference, and (2) this device must accept any interference, including interference that
may cause undesired operation of the device.
To reduce potential radio interference to other users, the antenna type and its gain should
be so chosen that the equivalent isotropically radiated power (e.i.r.p.) is not more than
that permitted for successful communication.
This device has been designed to operate with the antennas and cables listed in
Authorized Antennas and Authorized Cables tables. Antennas or cables not included in
these lists are strictly prohibited for use with this device.
To comply with IC RF exposure limits for general population/uncontrolled exposure, the
antenna(s) used for this transmitter must be installed to provide a separation distance of
at least 25 cm from all persons and must not be collocated or operating in conjunction
with any other antenna or transmitter.

16 Hardware Overview
Hardware Interfaces
Antenna Connections
The M6e supports four monostatic bidirectional RF antennas through four MMCX
connectors: labeled J1 through J4 on the module. See Cables and Connectors for more
information on antenna connector parts.
The maximum RF power that can be delivered to a 50 ohm load from each port is 1.4
Watts, or +31.5 dBm (operation above 30dBm requires a professional installer).
Note
The RF ports can only be energized one at a time.
Antenna Requirements
The performance of the M6e is affected by antenna quality. Antennas that provide good
50 ohm match at the operating frequency band perform best. Specified sensitivity
performance is achieved with antennas providing 17 dB return loss or better across the
operating band. Damage to the module will not occur for any return loss of 1 dB or
greater. Damage may occur if antennas are disconnected during operation or if the
module sees an open or short circuit at its antenna port.
Antenna Detection
To minimize the chance of damage due to antenna disconnection, the M6e supports
antenna detection. Detection can be done automatically or manually, the choice of which
is configured through API calls. Regardless of how it’s used it is generally recommend
that antenna detection be enabled as it helps protect the module from possible damage
due to return losses less than 1 dB.
Digital/Power Connector
The digital connector provides power, serial communications signals, shutdown and reset
signals to the M6e module, and access to the GPIO inputs and outputs. These signals are
provided through connector part number: Molex 53261-1571 - 1.25mm pin centers, 1

63811-0300. See Cables and Connectors for more information on typical cable parts.
Control Signal Specification
TTL Level UART Interface
The module communicates to a host processor via a TTL logic level UART serial port or
via a USB port. Both ports are accessed on the 15-pin Digital/Power Connector. The TTL
logic level UART supports complete functionality. The USB port supports complete
functionality except the lowest power operational mode.
Note
Power Consumption specifications apply to control via the TTL UART.

TTL Level RX
V-Low: -0.3 to 0.6 VDC
V-High: 2.2 to 5 VDC
(Tied to ground through a 10kOhm pull-up resistor. It is not harmful, but not
recommended to drive the input above 3.3 V.)
A level converter could be necessary to interface to other devices that use standard 12V
RS232. Only three pins are required for serial communication (TX, RX, and GND).
Hardware handshaking is not supported. The M6e serial port has an interrupt-driven
FIFO that empties into a circular buffer.
The connected host processor’s receiver must have the capability to receive up to 256
bytes of data at a time without overflowing.
Baud rates supported:
– 9600
– 19200
– 38400
– 115200
– 230400
– 460800
– 921600
Note
The baudrate in the Boot Loader mode depends on whether the module
entered the bootloader mode after a power-up or through an assert or “boot
bootloader” user command. Upon power up if the Reset Line is LOW then the
default baud rate of 9600 will be used. If the module returns to the
bootloader from Application Firmware mode, then the current state and
baudrate will be retained.
USB Interface
Supports USB 2.0 full speed device port (12 Megabits per second) using the two USB
pins (USB_DM and USB_DP).

General Purpose Input/Output (GPIO)
The four GPIO connections, provided through the M6e Digital Connector Signal Definition,
may be configured as inputs or outputs using the MercuryAPI. The GPIO pins connect
through 100 ohm resistors to the high current PA0 to PA3 pins of the AT91SAM7X
processor. The processor data sheet can be consulted for additional details.
Pins configured as inputs must not have input voltages that exceed voltage range of -0.3
volts to +5.5 volts. In addition, during reset the input voltages should not exceed 3.3V.
Outputs may source and sink 16 mA. Voltage drop in the series 100 ohm resistor will
reduce the delivered voltage swing for output loads that draw significant current.
Input Mode
– TTL compatible inputs,
– Logic low < 0.8 V,
– Logic high > 2.0V.
– 5V tolerant
Output Mode
– 3.3 Volt CMOS Logic Output with 100 ohms in series.
– Greater than 1.9 Volts when sourcing 8 mA.
– Greater than 2.9 Volts when sourcing 0.3 mA.
– Less than 1.2 Volts when sinking 8 mA.
– Less than 0.2 Volts when sinking 0.3 mA.
Module power consumption can be adversely affected by incorrect GPIO configuration.
Similarly, the power consumption of external equipment connected to the GPIOs can also
be adversely affected. The following instructions will yield specification compliant
operation.
On power up, the M6E module configures its GPIOs as outputs to avoid contention from
user equipment that may be driving those lines. The input configuration is as a 3.3 volt
logic CMOS input and will have a leakage current not in excess of 400 nA. The input is in
an undetermined logic level unless pulled externally to a logic high or low. Module power
consumption for floating inputs is unspecified. With the GPIOs configured as inputs
and individually pulled externally to either high or low logic level, module power
consumption is as listed in the M6e Power Consumption table.
GPIOs may be reconfigured individually after power up to become outputs. This
configuration takes effect either at API execution or a few tens of milliseconds after power
up if the configuration is stored in nonvolatile memory. The configuration to outputs is

defeated if the module is held in the boot loader by Reset Line being held low. Lines
configured as outputs consume no excess power if the output is left open. Specified
module power consumption is achieved for one or more GPIO lines set as output and left
open. Users who are not able to provide external pull ups or pull downs on any given
input, and who do not need that GPIO line, may configure it as an output and leave it
open to achieve specified module power consumption.
Configuring GPIO Settings
The GPIO lines are configured as inputs or outputs through the MercuryAPI by setting the
reader configuration parameters /reader/gpio/inputList and /reader/gpio/outputList. Once
configured as inputs or outputs the state of the lines can be Get or Set using the gpiGet()
and gpoSet() methods, respectively. See the language specific reference guide for more
details.
Reset Line
Upon power up the RESET (pin 15) line is configured as an input. The input value will
determine whether the Boot Loader will wait for user commands or immediately load the
Application Firmware image and enter application mode. After that action is completed, this
line is configured as an output line. While the unit continues to be in bootloader the line is
driven high.
Once in application mode, the RESET line is driven low. if the module returns to the
bootloader mode, either due to an assert or “boot bootloader”, the RESET line will again
be driven high.
To minimize power consumption in the application, the RESET line should be either left
open or pulled weakly low (10k to ground).
