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 23cm is
maintained between the radiator (antenna) & user’s/nearby people’s body at all
times.
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 23cm 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” “

14 Mercury6e Introduction
Hardware Interfaces
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 Watt,
or +30 dBm.
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

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.

(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).
Hardware Interfaces
Hardware Overview 19
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
Hardware Interfaces
20 Hardware Overview
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).
Power Requirements
Hardware Overview 21
Power Requirements
RF Power Output
The M6e supports separate read and write power level which are command adjustable
via the MercuryAPI. Power levels must be between:
– Minimum RF Power = +5 dBm
– Maximum RF Power = +30 dBm (+0.0/- 0.5 dB accuracy above +15 dBm)
Note
Maximum power may have to be reduced to meet regulatory limits, which
specify the combined effect of the module, antenna, cable and enclosure
shielding of the integrated product.
Power Supply Ripple
The following are the minimum requirements to avoid module damage and to insure
performance and regulatory specifications are met. Certain local regulatory specifications
may require tighter specifications.
5 Volt +/- 5%,
Less than 25 mV pk-pk ripple all frequencies,
Less than 11 mV pk-pk ripple for frequencies less than 100 kHz,
No spectral spike greater than 5 mV pk-pk in any 1 kHz band.

Boot Loader
28 Firmware Overview
Boot Loader
The boot loader provides low-level functionality. This program provides the low level
hardware support for configuring communication settings, loading Application Firmware
and storing and retrieving data to/from flash.
When a module is powered up or reset, the boot loader code is automatically loaded and
executed.
Note
Unlike previous ThingMagic modules (M4e and M5e) the M6e bootloader
should effectively be invisible to the user. The M6e is by default configured
to auto-boot into application firmware and for any operations that require the
module be in bootloader mode the MercuryAPI will handle the switching
automatically.
Application Firmware
Firmware Overview 29
Application Firmware
The application firmware contains the tag protocol code along with all the command
interfaces to set and get system parameters and perform tag operations. The application
firmware is, by default, started automatically upon power up.
Programming the M6e
Applications to control the M6e module and derivative products are written using the high
level MercuryAPI. The MercuryAPI supports Java, .NET and C programming
environments. The MercuryAPI Software Development Kit (SDK) contains sample
applications and source code to help developers get started demoing and developing
functionality. For more information on the MercuryAPI see the MercuryAPI Programmers
Guide and the MercuryAPI SDK, available on the ThingMagic website.
Upgrading the M6e
New features developed for the M6e are made available to existing modules through an
Application Firmware upgrade, along with corresponding updates to the MercuryAPI to
make use of the new features. Firmware upgrades can be applied using the MercuryAPI
to build the functionality into custom applications or using the MercuryAPI SDK demo
utilities.
Verifying Application Firmware Image
The application firmware has an image level Cyclic Redundancy Check (CRC) embedded
in it to protect against corrupted firmware during an upgrade process. (If the upgrade is
unsuccessful, the CRC will not match the contents in flash.) When the boot loader starts
the application FW, it first verifies that the image CRC is correct. If this check fails, then
the boot loader does not start the application firmware and an error is returned.
Custom On-Reader Applications
30 Firmware Overview
Custom On-Reader Applications
The M6e does not support installing customer applications on the reader. Continuous
reader, tag streaming, scripting and other methods of configuring the module to operate in
an autonomous or semi-autonomous reading modes maybe supported through the
MercuryAPI but custom application cannot be installed on the module.
Communication Protocol 31
Communication Protocol
The following section provides an overview of the low level serial communications
protocol used by the M6e.
Serial Communication Protocol
32 Communication Protocol
Serial Communication Protocol
The serial communication between a computer (host) and the M6e is based on a
synchronized command-response/master-slave mechanism. Whenever the host sends a
message to the reader, it cannot send another message until after it receives a response.
The reader never initiates a communication session; only the host initiates a
communication session.
This protocol allows for each command to have its own timeout because some
commands require more time to execute than others. The host must manage retries, if
necessary. The host must keep track of the state of the intended reader if it reissues a
command.
Host-to-Reader Communication
Host-to-reader communication is packetized according to the following diagram. The
reader can only accept one command at a time, and commands are executed serially, so
the host waits for a reader-to-host response before issuing another host-to-reader
command packet.

CCITT CRC-16 Calculation
The same CRC calculation is performed on all serial communications between the host
and the reader. The CRC is calculated on the Data Length, Command, Status Word, and
Data bytes. The header is not included in the CRC.

User Programming Interface
The M6e does not support programming to the serial protocol directly. All user interaction
with the M6e must be performed using the MercuryAPI.
The MercuryAPI supports Java, .NET and C programming environments. The
MercuryAPI Software Development Kit (SDK) contains sample applications and source
code to help developers get started demoing and developing functionality. For more
information on the MercuryAPI see the MercuryAPI Programmers Guide and the
MercuryAPI SDK, available on the ThingMagic website.

Antenna Ports
Functionality of the Mercury6e 39
Antenna Ports
The M6e has four monostatic antenna ports. Each port is capable of both transmitting and
receiving. The modules also support Using a Multiplexer, allowing up to 16 total logical
antenna ports, controlled using two GPIO lines and the internal physical port J1/J2/J3/J4
switching.
Note
The M6e does not support bistatic operation.
Using a Multiplexer
Multiplexer switching is controlled through the use of the internal module physical port J1/
J2/J3/J4 switch along with the use of one or more of the General Purpose Input/Output
(GPIO) lines. In order to enable automatic multiplexer port switching the module must be
configured to use Use GPIO as Antenna Switch in /reader/antenna/
portSwitchGpos.
Once the GPIO line(s) usage has been enabled the following control line states are
applied when the different Logical Antenna settings are used. The tables below show the
mapping that results using GPIO 1 and 2 for multiplexer control (as is used by the
ThingMagic 1 to 4 multiplexer) allowing for 16 logical antenna ports.
Note
The Logical Antenna values are static labels indicating the available control
line states. The specific physical antenna port they map to depends on the
control line to antenna port map of the multiplexer in use. The translation
from Logical Antenna label to physical port must be maintained by the
control software.

Settling time is the time between the control lines switching to the next
antenna setting and RF turning on for operations on that port. This allows
time for external multiplexer’s to fully switch to the new port before a signal is
sent, if necessary. Default value is 0.
Tag Handling
Functionality of the Mercury6e 43
Tag Handling
When the M6e performs inventory operations (MercuryAPI Read commands) data is
stored in a Tag Buffer until retrieved by the client application, or streamed directly to the
client if operating in Streaming mode [Not Yet Implemented].
Tag Buffer
The M6e uses a dynamic buffer that depends on EPC length and quantity of data read.
As a rule of thumb it can store a maximum of 1024 96-bit EPC tags in the TagBuffer at a
time. Since the M6e supports streaming of read results the buffer limit is, typically, not an
issue. Each tag entry consists of a variable number of bytes and consists of the following
fields:
The Tag buffer acts as a First In First Out (FIFO) — the first Tag found by the reader is the
first one to be read out.
Tag St r eam ing
When reading tags during inventory operations (MercuryAPI Reader.Read() and
Reader.StartReading()) by default the M6e “streams” the tag results back to the
host processor. This means that tags are pushed out of the buffer as soon as they are
processed by the M6e and put into the buffer. The buffer is put into a circular mode that
keeps the buffer from filling. This allows for the M6e to perform continuous search
operations without the need to periodically stop reading and fetch the contents of the
buffer. Aside from not seeing “down time” when performing a read operation this behavior
is essentially invisible to the user as all tag handling is done by the MercuryAPI.

Tag Read Meta Data
Tag Read Meta Data
44 Functionality of the Mercury6e
Tag Read Meta Data
In addition to the tag EPC ID resulting from M6e inventory operation each TagReadData
(see MercuryAPI for code details) contains meta data about how, where and when the tag
was read. The specific meta data available for each tag read is as follows:
Tag Read Meta Data
Meta Data Field Description
Antenna ID The antenna on with the tag was read. If the same tag is read
on more than one antenna there will be a tag buffer entry for
each antenna on which the tag was read. When Using a Multi-
plexer, if appropriately configured, the Antenna ID entry will
contain the logical antenna port of the tag read.
Read Count The number of times the tag was read on [Antenna ID].
Timestamp The time the tag was read, relative to the time the command to
read was issued, in milliseconds. If the Tag Read Meta Data is
not retrieved from the Tag Buffer between read commands
there will be no way to distinguish order of tags read with dif-
ferent read command invocations.
Tag Data When reading an embedded TagOp is specified for a Read-
Plan the TagReadData will contain the first 4 bytes of data
returned for each tag.
Note: Tags with the same TagID but different Tag Data
can be considered unique and each get a Tag
Buffer entry if set in the reader configuration
parameter /reader/tagReadData/
uniqueByData. By default it is not.
Frequency The frequency on which the tag was read
Tag Phase Average phase of tag response in degrees
LQI/RSSI The receive signal strength of the tag response in dBm.
GPIO Status The signal status (High or Low) of all GPIO pins when tag was
read.
Power Management
Functionality of the Mercury6e 45
Power Management
The M6e is designed for power efficiency and offers several different power management
modes. The following power management modes affect the power consumption during
different periods of M6e usage and impact performance in different ways. The available
power management modes are:
Power Modes - set in /reader/powerMode - Controls the power savings when the M6e
is idle.
Transmit Modes - set in
Power Modes
The Power Mode setting (set in /reader/powerMode) allows the user to trade off
increased RF operation startup time for additional power savings. The details of the
amount of power consumed in each mode is shown in the table under Power
Consumption. The behavior of each mode and impact on RF command latency is as
follows:
Power Mode 0 – In this mode, the unit operates at full power to attain the best
performance possible. This mode is only intended for use in cases where power
consumption is not an issue. This is the default Power Mode at startup.
Power Mode 1 – This mode may add up to 50 ms of delay from idle to RF on when
initiating an RF operation. It performs more aggressive power savings, such as
automatically shutting down the analog section between commands, and then
restarting it whenever a tag command is issued.
Power Mode 2 – This mode essentially shuts down the digital and analog boards,
except to power the bare minimum logic required to wake the processor. This mode
may add up to 100 ms of delay from idle to RF on when initiating an RF operation.
Power Mode 2 is not supported when using the USB interface.
Note
See additional latency specifications under Event Response Times.
Transmit Modes
The Transmit Mode setting (set in /reader/radio/enablePowerSave) allows the
user to trade off RF spectral compliance with the Gen2 DRM Mask for increased power
savings while transmitting. The details of the amount of power consumed in each mode is
shown in the table under Power Consumption. The behavior of each mode is as follows:
Power Management
46 Functionality of the Mercury6e
DRM Compliant Mode
This mode maximizes performance in dense reader environments, minimizing
interference when used with other M6e or similar DRM-compliant readers, and is fully
compliant with the Gen2 DRM spectral mask.
Power Save Mode (non-DRM Compliant)
This mode reduces the power consumption during RF operations but is not 100%
compliant with the DRM spectral mask. This can result increased interference with other
readers and reduce overall systems performance.

FAULT_NO_TAGS_FOUND – (400h)
Cause
A command was received (such as like read, write, or lock) but the operation failed. There
are many reasons that can cause this error to occur.
Here is a list of possible reasons that could be causing this error:
No tag in the RF field
Read/write power too low
Antenna not connected
Tag is weak or dead
Solution
Make sure there is a good tag in the field and all parameters are set up correctly. The best
way to check this is to try few tags of the same type to rule out a weak tag. If none
passed, then it could be SW configuration such as protocol value, antenna, and so forth,
or a placement configuration like a tag location.
FAULT_NO_PROTOCOL_DEFINED – 401h
Cause
A command was received to perform a protocol command but no protocol was initially
set. The reader powers up with no protocols set.
Solution
A protocol must be set before the reader can begin RF operations.

A demo application which supports multi-protocol reading and writing is provided in the
MercuryAPI SDK package. The source code for this example is included in the
MercuryAPI SDK package under /cs/samples/M6e-Read-Write-Demo-Tool. See the
MercuryAPI Programming Guide for details on using the MercuryAPI.
Demo Tool Notes
The region is only changed upon initialization. You must disconnect the reader,
change the region, and then “Initialize Reader” to change this value.
The protocol search display is only updated when one of the “Read” buttons is
pressed, not when the choice is made via the pull-down menu
“Read on all connected antennas” automatically activates antenna detection and will
ignore ports with an undetectable antenna. To read on these ports, the antenna port
must be explicitly selected.
The “Total tags read in x seconds” display only works for the “Read Once” function,
not Start/Stop Reads.
When “Start Reads” is clicked the M6e will read for the specified timeout with a 2
second delay (RF off) between reads. It is not a continuous read.
