ThingMagic M6e User Guide
1 Introduction
This document applies to the ThingMagic M6e high-performance, 4-port Ultra High Frequency (UHF)
RAIN® Radio Frequency Identification (RFID) module, as well as the M6e-A, M6e-PRC, and M6e-JIC
modules. All versions are referred to as M6e in this manual, with any exceptions expressly noted.
ThingMagic M6e is a high performance, embedded module that you can integrate with other systems to
create RFID-enabled products. This document is for hardware designers and software developers.
Applications to control the M6e module and derivative products can be written using the high level
MercuryAPI Ver. 1.29.4 and later. 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 www.jadaktech.com. Note that
the M6e-JIC module requires firmware version 1.21.0 or higher.
M6e Variations
There are four hardware variations of this module.
M6e
Designed to operate in the North American (902-928 MHz) and European (865-858 MHz) regulatory
regions. The North American region is limited to a transmit power of +30 dBm to conform to FCC
regulations for unrestricted use of a module of this type.
M6e-A
Operates in the same bands as the M6e module but will transmit at power levels up to +31.5 dBm in the
North American region. There are additional restrictions that a user must adhere to operate a module of this
power level in regions that adhere to FCC regulations.
M6e-PRC
Obsolete. This module was designed for the Chinese market and operates in both the high China band
(920 to 925 MHz) and the low China band (840 to 845 MHz). It has been replaced by the M6e-JIC module.
M6e-JIC
This module is designed to meet the demanding requirements for high power UHF RFID modules in China
(920 to 925 MHz), Japan (916.8 to 920.8 MHz), and Israel (915 to 917 MHz) bands.
Release Notes
The information in this document is relevant to M6e modules with Firmware Ver. 1.21.2 and later. This
firmware is compatible with the M6e, M6e-A and M6e-JIC modules. This firmware is not compatible with
any other ThingMagic modules such as the Micro or Nano modules.
M6e firmware version 1.21.2 has been developed in conjunction with version 1.29.4 of the MercuryAPI and
should be used with that version (or higher) to achieve best results. Previous versions of the API will not
support all the features of this firmware release. See the API release notes and MercuryAPI Programmers
Guide for further information on its features and functions.

ThingMagic M6e User Guide
2 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
(regulatory requirements permitting).
NOTE: The RF ports can only be energized one at a time.
NOTE: FCC/NA Region max RF power is 30 dBm for the M6e module. For 31.5 dBm operation in the FCC/
NA Region the M6e-A module must be purchased.
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. (A higher numerical value indicates a better
match.) 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.
•
Automatically if the antenna passes DC current.
•
Manually by doing periodic checks of the ability of ports to pass DC.
•
Manually by doing periodic checks to determine if the return loss is below a value that indicates an
antenna is present (a value of -10 dBm is a good threshold).
Regardless of how the reader is used, it is generally recommended that antenna detection be enabled as it
helps protect the module from possible damage.
For antennas to be detected automatically by DC current, the M6e antenna must pass some DC current
across the center pin and ground, i.e., must present between 0 Ohms and 10 kOhms DC resistance.

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 amp per pin rating, which mates with Molex
housing p/n 51021 -1500 with crimps p/n 63811-0300. See Cables and Connectors for more information on
typical cable parts.

ThingMagic M6e User Guide
Control Signal Specification
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.
NOTE: It is not recommended to use the UART interface when planning to operate the module in Tag
Streaming/Continuous Reading mode. The UART interface (both the module side and the host side)
cannot detect physical disconnections, as can the USB Interface, simplifying reconnection.
TTL Level UART Interface

(Tied to ground through a 10k ohm pull-down resistor)
A level converter could be necessary to interface to other devices that use standard 12V RS232. Only three
pins are used 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.

NOTE: The baud rate 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 115200 will be used. If the module returns
to the bootloader from Application Firmware mode, then the current state and baud rate will be
retained.

ThingMagic M6e User Guide
USB Interface
Supports USB 2.0 full speed device port (12 Megabits per second) using the two USB pins (USB_DM and
USB_DP).
Serial Number Added to USB Device Descriptor
Adding a serial number to the USB device descriptor allows the host to assign a COM port number which
follows the device regardless of which physical USB port it is plugged into.
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. Consult the M6e Specifications 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

•
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 inputs 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 automated configuration into outputs is prevented if the module is held in the boot
www.JADAKtech.com
ThingMagic M6e User Guide
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 line (pin 15) is configured as an input. The input value will determine whether
the Boot Loader will wait for user commands (if pulled LOW) or immediately load the Application Firmware
image and enter application mode (if left open or pulled up). After that action is completed, the line is
configured by the firmware as an output line. Whenever the module is in bootloader the line is in the
bootloader state and 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 (1.5k ohm to ground).
See Note about baud rate applicable when using TTL Level UART Interface.
Power Requirements
RF Power Output
The M6e supports separate read and write power levels which are command adjustable via the
MercuryAPI. Power levels must be between:
•
Minimum RF Power = +5 dBm
•
Maximum RF Power = +31.5 dBm (+/- 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.
NOTE: FCC regulations limit the maximum RF Power to 30 dBm in NA Region. For 31.5 dBm operation
in the NA Region the M6e-A must be purchased.
Special RF Power Output Requirements for the M6e-A
Warning:
Operation of the M6e-A requires professional installation to correctly set the TX power for
the RF cable and antenna selected.
www.JADAKtech.com
ThingMagic M6e User Guide
Power Settings for Authorized Antennas and Cables
The M6e-A has been designed to operate with the antennas listed in Authorized Antennas list using the
cables in the M6e-A Authorized Cables list. For any combination of antenna and cable the maximum RF
power is determined from antenna gain (Max Linear Gain value from antenna list) and antenna cable loss
(Insertion Loss value from cable list) using the formula:
Pmax = 36 dBm - Antenna Gain + Cable Loss
For example, for the Laird S8658WPL and the ThingMagic CBL-P6 6ft cable the following calculation can
be performed:
Max linear antenna gain = 6 dBiL
Minimum cable insertion loss = 0.8 dB
Pmax = 36 - 6 + 0.8 = 30.8 dBm
The maximum RF power that may be set using this configuration is 30.8 dBm (see Warning above).
Power Supply Ripple
The following are the minimum requirements to avoid module damage and ensure performance and
regulatory specifications are met. Certain local regulatory specifications may require tighter specifications.
•

Environmental Specifications
Operating Temperature
The M6e module may be considered as a single electronic component. It is designed so that all the internal
components have safe margins to their thermal limits when the heat spreading plate (bottom, non-labeled
side) does not exceed 70°C. The heat spreading plate temperature must not exceed 70° C. Heat sinking
will be required for high duty cycle applications.
When heat spreading plate reaches 70°C, the RF Shield (top, antenna connector side) may exceed 70°C,
which is acceptable.

NOTE: Survival level varies with antenna return loss and antenna characteristics. See ElectroStatic
Discharge (ESD) Considerations for methods to increase ESD tolerances.
Warning:
The M6e antenna ports may be susceptible to damage from Electrostatic Discharge
(ESD). Equipment failure can result if the antenna or communication ports are
subjected to ESD. Standard ESD precautions should be taken during installation and
operation to avoid static discharge when handling or making connections to the M6e
reader antenna or communication ports. Environmental analysis should also be
performed to ensure static is not building up on and around the antennas, possibly
causing discharges during operation.

3 Firmware Overview
New Features - Version 1.21.2
Margin Read Support for Monza6 Tags
MarginRead is an EPC Gen2 compliant custom command supported by tag chips with the “Integra” feature.
This command allows a reader to explicitly verify that the non-volatile memory (NVM) in the tag chip is not
weakly written, guaranteeing a minimum margin on NVM. It is used for quality control to ensure data
integrity and for failure analysis.
There are several ways that the MarginRead command could be used with Monza 6. A recommended use
of MarginRead is independent verification of the encoding quality, either on a sample basis or for diagnosis
during failure analysis.
MarginRead Description
When data is written to a tag using the Gen2 protocol, charge is built up in the memory cells until they
reach the appropriate level. Once that happens, the tag returns a "done" signal telling the interrogator
(reader) or encoding system that the write operation has completed successfully.
It is a known field issue that not all encoding systems properly wait for the "done" signal and instead
issue a read operation to check if the data is correct. A read operation may return correct data even if
the write operation did not complete successfully.
A partially charged memory cell might retain data for a limited time but then it will lose data integrity
over time. Data retention could be for an unpredictable amount of time from a few minutes to several
years.
A fully charged memory cell will retain data for a long period of time. Specifically, the Monza 6 tag is
expected to retain data for up to 50 years.
The MarginRead command allows customers to check if Monza 6 tag chip memory cells are fully
charged.
MarginRead may be used for diagnostics for data integrity issues in the field. If MarginRead indicates
an issue, then the encoding method should be investigated.
Refer Mercury API v1.29.4 release notes for API commands to work with this functionality.
NXP UCODE7 Configuration Support
Prior to UCODE 7, NXP supported a set of custom commands that could change the configuration word
values. Unfortunately, these commands that were developed for the G2i line of tags do not work for the
UCODE 7 tags. A new custom command has been implemented in M6e FW to change NXP UCODE7
configuration word for M6e modules (Nano does not support custom commands).
UCODE7 no longer supports ChangeConfig commands. An alternative way to change the configuration
word for UCODE7 tags has been developed.
UCODE7 configuration word contains 2 different types of bits:

1. Action bits: meant to trigger a feature upon a SELECT command on the related bit:
Parallel encoding (at address 0x202)
Tag Power indicator (at address 0x204)
2. Permanent bits: permanently stored bits in the memory
Max. Backscatter Strength (at address 0x209)
PSF Alarm bit (at address 0x20F)
Refer Mercury API v1.29.4 release notes for API commands to work with this functionality.
Gen2 Parameters in Metadata
Now that modification of the Gen2 parameters are allowed at will, it is desirable to include current Gen2
settings as metadata when tags are read so that the active setting under which the tag was read is
reported.
For example, Gen2 Q value can change dynamically so a user trying to determine the best static value
would benefit from knowing the value that the automated algorithm selected. Gen2 parameters included in
metadata are:
•
Gen2 Q
•
Gen2 Link Frequency
•
Gen2 Target
Gen2 Q, BLF and Target parameters have been added to the TagReadData.TagMetadata method. The
Read code sample in the MercuryAPI SDK shows how to activate this functionality.
Support for Acura Gen2V2 Tags
NMV2D tag support has been added in M6e FW, which returns 352 (256+96) bits in TAM2 reply for
ProtModes 0x02 and 0x03 and 256 bits for ProtModes 0x00 and 0x01. Previous release version of FW
v1.7.1 replies with 256 bits irrespective of any ProtMode.
The NMV2D tag supports the same set of commands as NXP UCODE AES tag except following:
•
NXP UCODE AES tag chip only supports ProtMode=1 while NMV2D tag supports ProtModes=0,1,2,3.
•
Untrace-Access and Untrace-Authen commands do not work for NMV2D tag as they do for UCODE AES
tag.
Refer to the Authenticate, ReadBuffer and Untraceable code samples in the MercuryAPI SDK to test this
functionality.
Support for GEN2V2 Embedded Tag Ops
In previous firmware releases, GEN2V2 operations that supported the NXP UCODE DNA tag were only
available as stand-alone, single tag functions. Now support for embedded tag operations has been added
for both NXP UCODE DNAtag and the NMV2D tag. This allows for high speed secure reading in
Asynchronous modes.
Refer to the Authenticate, ReadBuffer and Untraceable code samples in the MercuryAPI SDK to test this
functionality.
Gen2V2 Support
The M6e supports the Gen2V2 features of the NXP DNA tags. These features include:
www.JADAKtech.com
ThingMagic M6e User Guide
14
•
“Untraceable”. Ability to limit reading of all or part of EPC, TID and User memory fields by unauthorized
readers.
•
Ability to download and activate security keys.
•
Ability to authenticate tag using random challenge strings and AES encryption.
•
Ability to obtain memory data in encrypted form, which can be successfully decoded if the host knows
the key that has been activated on the tag.
•
Ability to obtain authentication and encrypted memory data from a tag buffer rather than the tag
backscattering that information to the reader immediately.
These capabilities are supported in the 1.27 version of the API and may be demonstrated using code
samples and the version of Universal Reader Assistant which is distributed with the API.
Denatran Tag Support
The M6e module supports the Denatran extension to the Gen2 protocol as a licensed feature.
Configurable T4 for Gen2 Protocol
Some sensor tags use a Select command to trigger sensor reading. The time the reader waits between the
Select command and start of inventory (when the Query command is sent) is controlled by a Gen2
parameter called the “T4 timer.” This has been updated so that the T4 timer can be set to a larger value to
ensure sufficient time for the sensor tag to obtain its reading before having to report it to the reader.
The parameter ‘PROTOCOL_PARAM_GEN2_T4’ has been added to set/get the Gen2 T4 parameter with
sub command for 0x9b and allows T4 to be set in milliseconds.
T4 value is 4-byte in length and specified in milliseconds. Minimum value of T4 allowed for 250 kHz (25us,
12.5us, 62.5us Tari) is 440usec (0x1B8) and for 640 kHz (6.25us Tari) is 220usec (0xDC). Maximum value
allowed is 1sec (0xF4240). Here is an oscilloscope trace of the reader output signal showing the effect of
changing this setting.

ThingMagic M6e User Guide
15
Refer Mercury API v1.29.4 release notes for API commands to work with this functionality.
Ability to “Read Data” Immediately After Sending a “Write EPC” or “Write Data” Command
Some sensor tags require the module to write to a memory bank to trigger the sensor measurement, then
read the sensor data field without dropping power between if the two operations are done as separate
commands. This functionality supports streamlining read-then-write operations for other applications as
well.
Read Data support has been added as an option for the Write EPC and Write Bank Data commands. This
allows the module to read the data from any of the memory banks following a successful write operation of
data to any memory bank (or write EPC) through a single command. The standard commands to Write Tag
Data and Write Tag EPC optionally includes the read memory bank, read word address, and read count to
implement this feature.
For more details on the application interface, refer to WriteTag code sample in the MercuryAPI SDK.
Decoupling Antenna Selection from AsyncOnTime
Previously when reading continuously, the reader returned to antenna one (or the first antenna in the
configured list) at the beginning of each AsynchOnTime cycle. This encouraged users to configure a high
value for AsyncOnTime to ensure all antennas would be activated each read cycle. Now some of the
settings can be changed without interrupting reading and take effect only at the beginning of the next
AsyncOnTime cycle, allowing users to set this value as low as possible.
www.JADAKtech.com
ThingMagic M6e User Guide
16
The antenna selection algorithm has been changed to recall the last antenna that was active in the
previous read cycle and start with that antenna for the next AsyncOnTime cycle. This way, the active
antenna cycles through the list with regularity and the AsynchOnTime can be optimized so on-the-fly
settings take effect as quickly as possible.
The ReadAsync code sample can be run to see the effect of this change.
Refer Mercury API v1.29.4 release notes for API commands to test this functionality.

Any channel frequency can be requested that is between the upper and lower bounds, but
the module will silently round down to the nearest channel that is the lower bound plus an
integer multiple of quantization steps.
The new Asian regions have been added to Reader.Region method. Refer Mercury API v1.29.4 release
notes for more information.
Support for Set/get Quantization Value and Minimum Frequency in Open Region
The Open region as defined in previous releases was intended for testing only. To permit the most flexibility
in defining channels, it allowed a minimum channel step size (quantization) of 25 kHz. The Open region is
not recommended to support channel plans which could not be easily accommodated by changing the hop
www.JADAKtech.com
ThingMagic M6e User Guide
19
table of existing regions, because such a small step size will result in lower channel frequency stability.
(This setting not only defines the minimum step size that can be set, but also represents how often the
channel is nudged back to its desired value, with more frequent nudges creating a more stable channel.)
To allow the Open region to be used more flexibly, the setting of the quantization value is now permitted. It
may be any value between 15 kHz and 6 MHz but must divide evenly into 6 MHz (6000 kHz). If not, an error
will be returned (error code number 105).
To permit the largest quantization value possible, setting the minimum frequency value for the Open region
is allowed. (Smaller quantization values are often driven by the rule that all channels must be an integral
multiple of the quantization value above the minimum frequency value.)
Only the Open region supports changing of the quantization value. Quantization values less than 100 kHz
are not recommended except for laboratory testing to maintain a high degree of channel frequency stability
and prevent interference with other readers or RF services.
Refer to Mercury API v1.29.4 release notes to activate this functionality.
Operational Notes
When the Truncation filter is applied, the tags will return data even if the Access Password is not correct.

Boot Loader
The boot loader provides low-level functionality and 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. 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
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 www.jadaktech.com.
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 firmware, 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
The M6e does not support installing customer applications on the module. All reader configuration and
control is performed using the documented MercuryAPI methods in applications running on a host
processor.
The M6e supports Autonomous Operation, where configuration settings and a basic read plan can be
stored in the module and executed whenever the module is power up, or whenever it is both powered up
and a selected GPI line is asserted.
Autonomous Operation Support
A read plan can be saved which allows the module to automatically begin continuously reading, and
optionally return data memory values, whenever the module is powered or whenever one of its GPI lines is
asserted. An Autonomous Configuration Tool is available to configure the settings and read plan necessary
to implement this feature.

4 Communication Protocol
Serial Communication Protocol
The serial communication between a computer (host) and the M6e is based on a synchronized commandresponse/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.

The M6e does not support programming to the serial protocol directly. All user interaction with the M6e
must be performed using the MercuryAPI.

quiet for 100ms before transmitting on the
same channel again.
Multi-Channel Mode
• Set by leaving the default or manually
setting more than one frequency in the hop
table. In this mode the module will occupy
one of the configured channels for up to
four seconds, after which it may switch to
another channel and immediately occupy
that channel for up to four seconds. This
mode allows for continuous operation.

lower power channels the RF level will be
limited to the outer channels limit, 100mW or
+20dBm.
Note: With the M6e-PRC hardware the 840
to 845MHz band is also supported as
the PR2 region. It is not supported on
the standard M6e, M6e-A, or
M6e-JIC modules.

Open Region
No regulatory compliance
enforced
Allows the module to be manually configured
within the full capabilities supported by the
hardware, see Regional Frequency
Quantization table. No regulatory limits,
including: frequency range, channel spacing
and transmit power limits are enforced. The
Open Region should be used with caution.
The regional functionality is set using the MercuryAPI. Setting the region of operation configures the
regional default settings including:
•
Loads the Frequency Hop Table with the appropriate table for the selected region.
•
Sets the PLL Frequency Setting to the first entry in the hop table, even if the RF is off.
•
Selects the transmit filter, if applicable.
Frequency Setting
The modules have a PLL synthesizer that sets the modulation frequency to the desired value. Whenever
the frequency is changed, the module must first power off the modulation, change the frequency, and then
turn on the modulation again. Since this can take several milliseconds, it is possible that tags are powered
off during a frequency hop. In addition to setting the default regional settings, the M6e has commands that
allow the transmit frequency to be set manually.
Warning:
Use these commands with extreme caution. It is possible to change the module’s
compliance with the regional regulations.

Frequency Units
All frequencies in the M6e are expressed in kHz using unsigned 32-bit integers. For instance, a carrier
frequency of 915 MHz is expressed as 915000 kHz.
The hop table for any region may consist of any permitted channels within the frequency limits for that
region. A permitted channel is one that is at the lowest permitted frequency or is a multiple of the minimum
channel step size, up to the highest permitted frequency. The following table gives the frequency limits and
minimum channel step size for all regions.

and M6e-JIC have different ranges for their Open region. 840 to 845 MHz and 920
to 925 MHz for M6e-PRC, 915 to 925 MHz for the M6e-JIC.
The user may define channels in a hop table to the nearest kHz (within the high and low frequency limits)
without receiving an error message, but if that request is not for a permitted channel, the actual frequency
used by the reader will be the first permitted channel below the requested frequency. For example, in the
NA region, setting a frequency of 902,999 kHz results in a setting of 902,750 kHz.
An error message will result if an attempt is made to set channels outside of the allowed frequency range
for a region. Changing regions will automatically re-install the default hop table for that region, erasing any
custom channels which may have been defined.
Frequency Hop Table
The frequency hop table determines the frequencies used by the M6e when transmitting. The hop table
characteristics are:
•
Contains up to 62 frequencies.
•
Valid frequencies for the region currently selected.
•
Inability to change individual entries after uploading without reloading the entire table.
www.JADAKtech.com
ThingMagic M6e User Guide
•
26
Frequencies used in the order of entries in the table. If regulatory requirements state that channels must
be hopped in random order, then the frequency list of channels must be randomized before downloading
the hop table into the module.
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, that is, transmitting on one port and receiving on
another.
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.

Multiplexing up to 32 Ports
The M6e module can use 3 GPO lines to control an external multiplexer which expands one RF port to 8
RF ports.
The following table provides the list of all possible “logical” antenna ports and how the selection of that port
affects the GPO line state and which physical antenna is active. If you are using fewer than 3 GPO lines to
control the module or using fewer than the 4 physical ports, do not include the logical ports in your port list
that do not correspond to desired GPO and antenna configurations. When a port is not defined as a GPO
control, you can assume it is low with respect to the chart.
NOTE: Use of fewer than the maximum number of ports and GPO lines will result in gaps in the logical
antenna list. This is desirable because assigning additional GPO lines to multiplexer control will
not change the port assignments already established with fewer lines. If the non-contiguous
numbering is undesirable, you have the option to rename any logical port.

The additional GPO line is configured just like the first two, using the /reader/antenna/ portSwitchGpos
parameter. Once GPO lines are configured to act as multiplexer controls, you may use the virtual port
numbers as if they were physical ports on the reader.
Port Power and Settling Time
The M6e allows the power and settling time for each logical antenna to be set using the reader
configuration parameters /reader/radio/portReadPowerList and / reader/antenna/settlingTimeList,
respectively. The order the antennas settings are defined does not affect search order.
NOTE: 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 multiplexers to fully switch
to the new port before a signal is sent, if necessary. Default value is 0.

Support for Return Loss Measurement
The firmware estimates the return loss of individual antenna ports, based on multiple readings at multiple
channels within the active region. (For the North American region, with 50 channels, this measurement can
take as long as 600 msec). The return loss value can be obtained through the API by getting the “/reader/
antenna/returnloss” parameter value as well as by using the “CmdGetAntennaReturnLoss” method. The
sample code “ReaderStats” illustrates the recommended method for obtaining this information. The values
returned will look like this:
Antenna Return Loss
Antenna 1 | 30
Antenna 2 | 4
Which indicates a return loss of 30 dB for antenna 1, and 4 dB for antenna 2.
This measurement loses accuracy as the numbers increase due to the impact of internal signal reflections
that increasingly obscure the measurement of the small signal reflected only at the antenna.
The return loss is measured at an RF level of +15 dB to limit impact to other services that are running in the
same region while the return loss measurement is being made.
NOTE: The M6e uses a small amount of DC current to detect antennas. Use of this method to determine
if an antenna is present and of the return loss to determine if the antenna is tuned to the correct
frequency is the best way of ensuring maximum performance for the channel of operation.
Protocol Support
The M6e has the ability to support many different tag protocols. Using the MercuryAPI ReadPlan classes
the M6e can be configured to single or multi-protocol Read operations. The current protocols supported are
(some may require a license to enable):
•
ISO 18000-6C (Gen2)
•
IP-X
•
ISO 18000-6B
•
AEI ATA

Notes
Default
NOTE: It is important that the /reader/baudRate is greater than /reader/ gen2/BLF, in equivalent
frequency units. If it is not, then the reader could be reading data faster than the transport can
handle and send, and the reader’s buffer might fill up.
Protocol-Specific Functionality
The host can “get” many settings when it first connects to a module to determine whether the settings are
as desired or need to be changed. Now, an additional “get” can determine if any optional Gen2 extensions
have been enabled for the module. (Only one custom extension is offered - IAV Denatran support.) The
parameter to get protocol extensions is /reader/Gen2/ProtocolExtension.
See the MercuryAPI Programmers Guide and language specific reference guides for details on supported
Gen2 command functionality.

IP-X
The M6e supports multiple IP-X profiles including the ability to specify the Return Link Frequency, encoding

which can operate under multiple profiles.
ISO 18000-6B
The M6e supports multiple ISO-18000-6B profiles including the ability to specify the Return Link
Frequency, encoding, Forward Link Rate and modulation scheme. The protocol options are set in the

Delimiter
ISO18000-6B tags support two delimiter settings on the transmitter. Not all tags support both delimiters,
some tags require the delimiter be set to 1, but the default is 4.
The delimiter setting is set using the MercuryAPI Reader Configuration Parameter:
/reader/iso180006b/delimiter
www.JADAKtech.com
ThingMagic M6e User Guide
33
In addition to setting the delimiter to 1, a TagFilter of the class ISO180006b.Select must be used in order to
read certain ISO18000-6b tags, specifically one of the following options must be used:
GROUP_SELECT_EQ
GROUP_SELECT_NE
GROUP_SELECT_GT
GROUP_SELECT_LT
GROUP_UNSELECT_EQ
GROUP_UNSELECT_NE
GROUP_UNSELECT_GT
GROUP_UNSELECT_LT
AEI ATA
AEI ATA Protocol with Stop Trigger Read Plan
The AEI ATA protocol is supported on the M6e module with an optional license key. The ATA protocol is
supported under a Stop Trigger Read Plan so that results can be provided continuously instead of at the
end of a read cycle.
Universal Reader Assistant now supports readers which have been licensed to read the AEI ATA or IP-X
protocols. The “Tag Inspector” tab can interpret the information in AEI ATA tags per the AAR S-918
encoding standard.
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 Tag Streaming/
Continuous Reading mode.
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:
Tag Buffer
Total Entry Size
Field
Size
Description
68 bytes
(Max EPC
Length = 496bits)
EPC
Length
2 bytes
Indicates the actual EPC length of the tag
read.
PC Word

62 bytes
Contains the tagʼs EPC value.
Tag CRC
2 bytes
The tagʼs CRC.
Tag Read Metadata
www.JADAKtech.com
ThingMagic M6e User Guide
34
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 Streaming/Continuous Reading
When reading tags during asynchronous inventory operations (MercuryAPI Reader.StartReading()) using
an /reader/read/asyncOffTime=0 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.
NOTE: It is recommended the USB Interface be used when operating the M6e in continuous reading
mode. When the TTL Level UART Interface is used, it is not possible for the module to detect a
broken communications interface connection and stop streaming the tag results.
Tag Read Metadata
In addition to the tag EPC ID resulting from M6e inventory operation each TagReadData (see MercuryAPI
for code details) contains metadata about how, where and when the tag was read. The specific metadata
available for each tag read is as follows:
Tag Read Metadata
Metadata 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
Multiplexer, 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 Metadata is
not retrieved from the Tag Buffer between read commands
there will be no way to distinguish order of tags read with
different read command invocations.
Tag Data
When reading an embedded TagOp is specified for a
ReadPlan the TagReadData will contain the first 128 words 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 (0°-180°).
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.
www.JADAKtech.com
ThingMagic M6e User Guide
35
Meta-data Control at Module Level
The meta-data selection information is transferred to the module and the module only reports desired
values, resulting in a small increase in performance under some circumstances. No additional configuration
parameters are necessary to take advantage of this feature.
Filtering on Tag Length and EPC Truncation
The Universal Reader Assistant can filter based on tag length and EPC truncation:
•
Only return tags if the EPC is of the expected length, which weeds out stray and phantom tags.
•
Only announces tags whose EPCs contain a certain beginning value and length. The desired EPC value
includes both the PC word (which gives the EPC length) and the desired starting value for EPC. Tags
do not respond if they do not have that start value and length; they only respond with the unique portion
of their EPC (not the shared prefix value) to increase performance.
Note that “EPC Truncate” is difficult to distinguish between a normal filter on EPC ID because the part of
the EPC that is not reported by the tag is appended to the EPC as reported in the tag results screen.
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 /reader/radio/enablePowerSave. Controls power savings while transmitting.
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 M6e Power Consumption. The behavior of each mode and impact on RF
command latency is as follows:
•
PowerMode.FULL – 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.
•
PowerMode.MINSAVE – This mode 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. This mode may add up to 50 ms of delay from idle to RF on when initiating an RF operation.
•
PowerMode.SLEEP – 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. PowerMode.SLEEP is not supported when using the
USB interface. Using the setting PowerMode.MEDSAVE is the same as SLEEP.
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:
www.JADAKtech.com
ThingMagic M6e User Guide
36
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.
Event Response Times
The following table provides some metrics on how long common M6e operations take. An event response
time is defined as the maximum time from the end of a command (end of the last bit in the serial stream) or
event (e.g. power up) to the response event the command or event causes.

Set the Duty Cycle for Continuous Reading
The module can control the duty cycle, allowing the host less interaction with the module and permitting
greater control under Autonomous Operation. The Autonomous Configuration Tool supports duty cycle
control, to complement support in emerging versions of module firmware. This allows the module firmware
to control duty cycle to save battery life and reduce temperature rise.
Change Settings During Continuous Reading
A subset of available settings can be changed while the reader is actively reading. This allows the host to
optimize settings on-the-fly. Settings that are supported during continuous reading are:
•
Global TX Read Power
•
Global TX Write Power

No special command is needed to set parameters during continuous reading. The API will automatically
send the correct command to the module based on its knowledge of the state the module is in.
Universal Reader Assistant can change settings during continuous reading. Any settings in the “Display
Gen2 Settings” category can be altered, as well as the global read and write power levels (although write
power is of limited use since the “write” tag operation cannot be specified under continuous reading in the
Universal Reader Assistant).

Changes to the power levels are applied silently. Changes to Gen2 parameters result in a pop-up progress
bar which disables further changes until the one you made is applied.
License Handling
The M6e module supports protocols and features that are activated by installation of a license key. The
Universal Reader Assistant Firmware Update panel is used to install license keys.

Federal Communication Commission (FCC) 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.

Protocol Fault Errors
Message
Code
Cause
Solution
FAULT_NO_TAGS_FOUN
400h
A command was received
(such as read, write, or lock)
but the operation failed. There
are many reasons that can
cause this error to occur,
including:
• No tag in the RF field
• Read/write power too low
• Antenna not connected
• Tag is weak or dead
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 tags of the
same type to rule out a weak tag.
If none passed, then it could be
software configuration such as
protocol value, antenna, and so
forth, or a placement configuration
like a tag location.
FAULT_NO_PROTOCOL_
DEFINED
401h
A command was received to
perform a protocol command
but no protocol was initially
set. The reader powers up
with no protocols set.
A protocol must be set before the
reader can begin RF operations.
FAULT_INVALID_PROTO
COL_SPECIFIED
402h
The protocol value was set to
a protocol that is not
supported with the current
version of software.
This value is invalid or this version
of software does not support the
protocol value. Check the
documentation for the correct
values for the protocols in use and
that you are licensed for it.
FAULT_WRITE_PASSED
_LOCK_FAILED
403h
During a Write Tag Data for
ISO18000-6B or UCODE, if
the lock fails, this error is
returned. The write command
passed but the lock did not.
This could be a bad tag.
Try to write a few other tags and
make sure that they are placed in
the RF field.
FAULT_PROTOCOL_NO_
DATA_READ
404h
A command was sent but did
not succeed.
The tag used has failed or does
not have the correct CRC. Try to
read a few other tags to check the
hardware/software configuration.
FAULT_AFE_NOT_ON

Appendix C: Environmental Considerations
ElectroStatic Discharge (ESD) Considerations
Warning:
The M6e antenna ports may be susceptible to damage from Electrostatic Discharge
(ESD). Equipment failure can result if the antenna or communication ports are
subjected to ESD. Standard ESD precautions should be taken during installation to
avoid static discharge when handling or making connections to the M6 reader
antenna or communication ports. Environmental analysis should also be performed
to ensure static is not building up on and around the antennas, possibly causing
discharges during operation.
ESD Damage Overview
In M6e-based reader installations where readers have failed without known cause, ESD has been found to
be the most common cause. Failures due to ESD tend to be in the M6e Power Amplifier (PA) section. PA
failures typically manifest themselves at the software interface in the following ways:
•
RF operations (read, write, etc.) respond with Assert - 7F01 - indicating a fatal error. This is typically due
to the module not being able to reach the target power level due to PA damage.
•
RF operations (read, write, etc.) respond with No Antenna Connected/Detected even when a known
good antenna is attached.
•
Unexpected Invalid Command errors, indicating command not supported, when that command had
worked previously. A command may become unsupported when the reader, during its self-protection
routines, has returned to the bootloader to prevent any further damage. This jump to boot loader caused
by power amp damage occurs at the start of any read tag commands.
Determining that ESD is the root cause of failures is difficult because it relies on negative result
experiments, i.e., it is the lack of failure after a configuration change, rather than a positive flag wave that
identifies it as ESD. Such flag waves are sometimes available at the unpackaged transistor level under high
power microscopy. The remoteness of microscopic examination from the installed field failures is indicative
of the high cost of using such analysis methods for investigating ESD issues. Most ESD issue resolutions
use the negative result experiments to determine success.
ESD discharges come with a range of values with vaying degrees. There will be a distribution of ESD
intensities in some installations of the bare M6e that have an ESD failure problem. There may be an issue
without knowledge of a limit in the statistics of those intensities. For the bare M6e equipped with the
mitigation methods described below, there may be an occasional ESD discharge that exceeds any given
mitigation, resulting in failure. Many installations will have some upper bound on the value of ESD events
given the geometry of that installation.
Several sequential steps are recommended for a) determining ESD is the likely cause of a given group of
failures, and b) enhancing the M6e’s environment to eliminate ESD failures. The steps vary depending on
the required M6e output power in any given application.
Identifying ESD as the Cause of Damaged Readers
The following are some suggested methods to determine if ESD has caused reader failures, i.e., ESD
diagnostics. Some of these suggestions have the negative result experiment issue.
www.JADAKtech.com
ThingMagic M6e User Guide
62
•
Return failed units for analysis.
Analysis should determine if it is the power amplifier that has failed, but won’t be able to definitively
identify that the cause is ESD. However, ESD is one of the more common causes of PA failure.
•
Measure ambient static levels with static meter, for example, AlphaLabs SVM2.
Note the static potentials floating detected. High static doesn’t mean discharges, but should be
considered cause for further investigation. High levels that keep changing are highly indicative of
discharges.
•
Touch some things around the antenna and operating area.
If you feel static discharges, that is an indication of what is in front of the antenna. What gets to the M6e
is also strongly influenced by the antenna installation, cabling, and grounding discussed above.
•
Use the mean operating time statistic before and after one or more of the changes listed below to
quantitatively determine if the change has resulted in an improvement. Be sure to restart your statistics
after the change.
Common Installation Best Practices
The following are common installation best practices to ensure the readers isn’t being unnecessarily
exposed to ESD, in even low risk environments. These should be applied to all installations, full power or
partial power, ESD or not:
•
Ensure that M6e, M6e enclosing housing (e.g., M6 reader housing), and antenna ground connection are
all grounded to a common low impedance ground.
•
Verify R-TNC knurled threaded nuts are tight. Don’t use a thread locking compound that would
compromise the grounding connection of the thread to thread mate. If there is any indication that field
vibration might cause the R-TNC to loosen, apply RTV or other adhesive externally.
•
Use antenna cables with double shield outer conductors, or full metallic shield semi rigid cables. JADAK
specified cables are double shielded and adequate for most applications. ESD discharge currents
flowing on the outer surface of a single shield coaxial cable have coupled to the inside of coaxial cables,
causing ESD failure. Avoid RG-58. RG-223 is preferred.
•
Minimize ground loops in coaxial cable runs to antennas. Tying both the M6e and antenna to ground
(per item 1) leads to the possibility of ground currents flowing along antenna cables. The tendency of
these currents to flow is related to the area of the conceptual surface marked out by the antenna cable
and the nearest continuous ground surface. When this conceptual surface has minimum area, these
ground loop currents are minimized. Routing antenna cables against grounded metallic chassis parts
helps minimize ground loop currents.
•
Keep the antenna radome in place. It provides significant ESD protection for the antenna’s metallic parts
and protects the antenna from performance changes due to environmental accumulation.
•
Keep careful track of serial numbers, operating lifetimes, and numbers of units operating in order to
determine the mean operating lifetime. This number indicates if you have a failure problem, ESD or
otherwise. After any given change, it also indicates whether things have improved and if the failures are
confined to one instantiation or distributed across your population.
Raising the ESD Threshold
For applications where full M6e power is needed for maximum tag read range and ESD is suspected, the
following components are recommended additions to the installation to raise the level of ESD the reader
can tolerate:
•
Select or change to an antenna with all radiating elements grounded for DC. The MTI MT-262031T(L,R)H-A is recommended. The Laird IF900-SF00 and CAF95956 are not recommended. The
grounding of the antenna elements dissipates static charge leakage, and provides a high pass
www.JADAKtech.com
ThingMagic M6e User Guide
63
characteristic that attenuates discharge events. (This also makes the antenna compatible with the M6e
antenna detect methods.)
•
Install a Minicircuits SHP600+ high pass filter in the cable run at the M6e (or Vega or other finished
reader) end. This additional component will reduce transmit power by 0.4 dB which may affect read
range in some critical applications. However the filter will significantly attenuate discharges and improve
the M6e ESD survival level.
NOTE: The SHP600+ is not rated for the full +31.5 dBm output of the M6e reader at +85°C. Operation at
reduced temperature is acceptable, but has not been fully qualified by JADAK.
•
Install a Diode Clamp* circuit immediately outboard from the SHP600 filter. This will reduce transmit
power by an additional 0.4 dB, but in combination with the SHP600 will further improve the M6e ESD
survival level.
* Not yet productized. Needs DC power. Contact rfid-support@jadaktech.com for details.
Further ESD Protection for Reduced RF Power Applications
In addition to the protective measures recommended above, for applications where reduced M6e RF power
is acceptable and ESD is suspected, the following protective measures can also be applied:
•
Install a one watt attenuator with a decibel value of +30 dBm minus the dBm value needed for tag power
up. Then run the reader at +30 dBm instead of reduced transmit power. This will attenuate inbound ESD
pulses by the installed decibel value while keeping the tag operation generally unchanged. Attenuators
of 6 dB have been shown to not adversely affect read sensitivity. Position the attenuator as close to the
M6e as feasible.
•
As described above, add the SHP600 filter immediately adjacent to the attenuator, on the antenna side.
•
If required, add Diode Clamp adjacent to the SHP600, on the antenna side.
Variables Affecting Performance
Environmental
Reader performance may be affected by the following environmental conditions:
•
Metal surfaces such as desks, filing cabinets, bookshelves, and wastebaskets may enhance or degrade
reader performance.
•
Antennas should be mounted far away from metal surfaces that may adversely affect the system
performance.
•
Devices that operate at 900 MHz, such as cordless phones and wireless LANs, can degrade reader
performance. The reader may also adversely affect the performance of these 900 MHz devices.
•
Moving machinery can interfere with the reader performance. Test reader performance with moving
machinery turned off.
•
Fluorescent lighting fixtures are a source of strong electromagnetic interference and, if possible, should
be replaced. If fluorescent lights cannot be replaced, keep the reader cables and antennas away from
them.
•
Coaxial cables leading from the reader to antennas can be a strong source of electromagnetic radiation.
These cables should be laid flat and not coiled.
Tag Considerations
There are several variables associated with tags that can affect reader performance:
www.JADAKtech.com
ThingMagic M6e User Guide
64
•
Application Surface: Some materials, including metal and moisture, interfere with tag performance. Tags
applied to items made from or containing these materials may not perform as expected.
•
Tag Orientation: Reader performance is affected by the orientation of the tag in the antenna field. The
ThingMagic antenna is circularly polarized, so it reads face-to but not edge-to.
•
Tag Model: Many tag models are available, each with its own performance characteristics.
Multiple Readers
•
The reader adversely affects performance of 900 MHz devices. These devices also may degrade
performance of the reader.
•
Antennas on other readers operating in close proximity may interfere with one another, thus degrading
performance of the readers. If antennas from different readers are facing each other, they should have
opposite polarity for best performance (e.g., right-hand polarized antenna facing a left-hand polarized
antenna).
•
Interference from other antennas may be eliminated or reduced by using either one or both of the
following strategies:
•
Affected antennas may be synchronized by a separate user application using a timemultiplexing strategy.
•
Antenna power can be reduced by reconfiguring the RF Transmit Power setting for the reader.
NOTE: Performance tests conducted under typical operating conditions at your site are recommended
to help optimize system performance.
