4 Hardware Overview
4.1
Ports and Connectors
4.1.1.1 Antenna Connections
The IZAR supports four monostatic bidirectional RF antennas through four Reverse Polarity TNC (abbreviated
to “RP-TNC”) connectors: labeled 1 through 4 on the IZAR (Figure 9).
The maximum RF power that can be delivered to a 50 ohm load from the external port is 1.4 Watts, (+31.5
dBm). Depending on the antenna used and the local regulations for your region of operation, the maximum
permitted level may be lower than this.
The RF ports can only be energized one at a time, but the reader can be configured to alternate between
antennas many times per second, often resulting in the appearance of continuous reading on all antennas.
Figure 9: IZAR RFID Antenna Ports
Antenna Requirements
The performance of the IZAR is affected by antenna quality. Antennas perform best if they provide good 50 ohm
match at the operating frequency band. The degree of antenna match is measured as a return loss, in negative
dBm units, with a higher numerical (more negative) value being a better match. Specified sensitivity
performance is achieved with antennas providing -17 dB return loss or better across the operating band.
Damage to the reader will not occur for any return loss of -1 dB or greater.
WARNING –
Damage may occur if antennas are disconnected during operation or if the IZAR sees
an open or short circuit at its antenna port.
WARNING – 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 23 cm is maintained between
the radiator (antenna) and people in front of the antenna at all times and must not be co-located or
operating in conjunction with any other antenna or transmitter unless appropriate additional proximity
restrictions are imposed.

4.1.1.3 Using Power over Ethernet (POE)
Another way of powering up the IZAR Reader is to use a single Ethernet cable that is connected to a
Power over Ethernet (PoE) network. In this configuration a power converter is not used.
To power up the IZAR Reader over a PoE network:
1. Connect one end of an Ethernet cable to the IZAR Reader
2. Connect the other end to a certified IEEE 802.3af compliant PoE port.
Note: For operation in the EU region, you must use the Ferrite Bead included with the IZAR Reader when
powering-up the Reader over a PoE network, in order to meet ETSI regulatory requirements. For the
Ferrite Bead to be effective, you must install the Ferrite Bead on the Ethernet cable at the end closest to
the IZAR Reader. Ideally, the Ferrite Bead should not be more than two inches away from the connector,
as shown in Figure below.
Figure 11: Ferrite Bead
When using PoE as a power source, the PoE must be supplied by a UL Listed ITE device.
When using PoE as a power source the unit cannot be connected to an Ethernet network with
outside plant routing, including a campus environment. The network must be contained within a
single building.
Do not use POE and DC power at the same time. If making a change, always disconnect one
before introducing the other.
4.1.1.4 Ethernet (“LAN/POE”)
The LAN interface is a 10/100 RJ45 jack with 2 indicator LEDs.
4.1.1.5 Micro USB (“Console”)
The USB 2.0 micro-USB client port looks like 3 interfaces to connected hosts:
1.
A serial “Gadget” port that provides access to the console interface
2.
A USB “thumb drive” interface that provides access to internal memory on which the USB drivers for
the console and USB LAN interfaces are stored
3.
A USB LAN interface (RNDIS). To connect to the USB console port, see Connecting to the USB
Console Port.

4.1.1.6 External Memory (“Micro SD”)
A Micro SD, 3.3 V, interface available for various standard and custom purposes. Future firmware versions are
anticipated to use this interface as a source of new firmware and for portable tag data storage.
4.1.1.7 Control and Indicator Interfaces (“GPIO”)
Four (4) Input and four 4 output opto-isolated GPIO lines, are available for customizing reader control and result
indication. The GPIO available consists of 4 lines of general purpose output, and 4 lines of general purpose
input. These lines are writeable and readable by user programs running on the reader. This is a 12-pin
connector. There is also supporting power and grounds to convert them into TTL level logic, in and out. See
Section 9:
Using GPIO
.
Figure 12: GPIO connector
4.1.1.8 Video Output Interface (“HDMI”)
The HDMI interface is not active at this time as we have been unable to find cables (with or without ferrite
beads) which will prevent RF radiation from the cables at levels higher than allowed by many regional
authorities.
4.1.1.9 USB Host
A USB 2.0 host interface provides host-USB connectivity (with 5V power) for various standard and custom
purposes. This interface will support a variety of accessories, such as wireless LAN interfaces, and adapters
that support other RFID technologies, such as Bluetooth Low Energy (BLE).

5 Programming Interfaces
5.1 Mercury API
Applications to control the IZAR Reader, and all ThingMagic reader products, can be written using the high level
MercuryAPI. The MercuryAPI supports Java, .NET and C (for on-reader applications) programming
environments. The MercuryAPI Software Development Kit (SDK) contains sample applications and source code
to help developers get started demonstrating and developing functionality. For more information on the
MercuryAPI see the MercuryAPI Programmers Guide and the MercuryAPI SDK, available on the ThingMagic
website.
5.2 Demo Applications
As the starting point for learning the capabilities of the IZAR Reader, and also a starting place for building
custom applications, a demo application is provided in the MercuryAPI SDK package. The executable for this
example is included in the MercuryAPI SDK package (available on jadaktech.com website) See the Universal-
Reader- Assistant User Guide (available on jadaktech.com website) for usage details.
5.3 LLRP
LLRP is the EPCglobal standard (http://www.gs1.org/epcrfid/epc-rfid-llrp/latest) used for communication
between the IZAR and a client application. The IZAR should be “drop-in compatible” with systems supporting
the standard LLRP protocol. Middleware such as BizTalk and WebSphere have standard LLRP adapters that
can work with the IZAR. We have also extended LLRP through custom extensions to support non-standard
configuration options and commands, which are supported by ThingMagic readers. We offer a package for
LLRP Commander which includes these extensions in XML format.
For more information on direct use of LLRP, the ThingMagic custom extensions and the open source LLRP
Toolkit please contact support (RFID-support@jadaktech.com).
5.4 On-Reader Applications
The IZAR supports running custom applications on the reader, built using the MercuryAPI C Language
interface. Most programs written using the C API can be compiled to run as a client application or run on the
reader. An application note explaining how to develop and distribute on-reader programs may be downloaded
from www.jadaktech.com.

Figure 13: IZAR Reader Interfaces
6 Setting Up the Reader
This section describes the steps necessary to setup all the necessary components and connect to the Reader’s
browser-based interface.
6.1 Equipment Required
To set up Single Reader Operation, you need the reader and some additional hardware. The additional
hardware required includes:
A computer with a web browser
Ethernet cable (CAT5e; shielded is recommended)
Antenna(s) which are tuned for the frequency range of operation.
Coax cable(s) (RP-TNC connectors)
Optionally, you should have a USB cable (PC type A connector to IZAR micro-USB connector)
in case console access is required.
Note: To initiate tag reading with the IZAR Reader, no host software is required aside from a browser. To set up
the Reader as part of a larger scale deployment that uses a LAN connection, refer to Networking Settings.
6.2 Setup Procedure
The steps required to set up and run the IZAR Reader are contained in the following sections:
Connecting Antenna(s) to the Reader
Powering Up the Reader
Connecting Your PC to the Reader
Communicating with the Reader using a Link-local Address
Logging On to the Reader
In this procedure, various interfaces will be described. They are shown in thre Figure below.
6.2.1.1 Connecting Antenna(s) to the Reader
The IZAR Reader supports up to four monostatic antennas. The default power setting is a convenient way to set
the power of the antennas, although per-antenna settings are supported. See Settings page for configuration
options. Before you apply power to the Reader, you must connect at least one antenna to an RFID antenna
port.
NOTE: Authorized antennas and cables have been certified for use with this reader are recommended. Local
regulations may permit antennas of the same type, but lower gain, to be used. See Appendix A: IZAR Antenna
and Cable Information.
ThingMagic IZAR User Guide
|
21
6.2.1.2 Powering Up the Reader
Power up the IZAR using a DC power supply.
NOTE: Sold separately to power up the IZAR Reader using a DC power supply:
1.
Plug the power supply into the Reader's DC 9 – 30V power input connector.
2.
Connect the extension cord to the power supply and plug it into a 100-240VAC power outlet.
The Reader immediately begins to power up. There is no on/off switch on the Reader. While the Reader is
powering up, the red RFID status LED, adjacent to the USB HOST connection, will be on. The Reader is ready
for operation after approximately 60 seconds when the LED is illuminated green.
Powering up using POE is supported. See 4.1.1.4
Ethernet (“LAN/POE”)
.
Do not use POE and DC power at the same time. If making a change, always disconnect one
before introducing the other.
6.2.1.3 Interpreting the Reader Indicator LEDs
The IZAR Reader has an operational status LED, near the USB HOST connector, which allow you to determine
the current operational readiness and activity of the IZAR Reader.
The colors displayed by the LED include:
Red LED on: Reader is starting up.
Red LED blinking: Reader is attempting to obtain an IP address using the default or configured
methods. (Reader can be accessed through the USB interface when in this state.)
Green LED on: Reader has a valid IP address and is ready for operation.
Green LED blinking: RF field is ON and the unit is attempting to read tags.
Alternate Red and Green LED blinking: Reader is being accessed through USB port and is actively
reading.
6.2.1.4 Connecting Your PC to the Reader
Network connectivity to the IZAR Reader is provided via its LAN/POE port. For instructions on connecting the
Reader to a network, see the section Networking Settings.
When connected directly to a computer, with default/factory configuration the reader will use Zero Configuration
networking (also referred to as Link Local or Automatic Private IP Addressing on Windows) to negotiate a valid
IP address.
To connect your Reader directly to your PC:
1.
Connect an Ethernet cable to your PC.
2.
Connect the other end of the Ethernet cable to the Reader’s LAN/POE port.
6.2.1.5 Communicating with the Reader using a Link-local Address
If you are using an operating system other than Windows 7, consult your network administrator regarding how
to set up your PCʼs TCP/IP connection.
If you are using Windows 7, perform the following steps to set up (or verify) your PC's TCP/IP connection. On
most PCs this is the default configuration:
1.
Select Start from the Start bar, and then select Control Panel.
2.
Under Network and Internet, select “View network status and tasks”.
3.
In the left menu select “Change adapter settings”.
4.
The Local Area Connection Status window appears, as shown in Figure 12.
NOTE: Link-local addressing is the default fallback method if no DHCP server is present. If this is your preferred
IP addressing method, obtaining a Link Local IP address will occur much more quickly if it is made the primary
IP address source in instead of a fallback method. See Section 7: Network Settings.

Network Settings
You can set up the IZAR Reader to use a DHCP server, Link Local peer negotiation, or manual entry as an IP
address source. By default, the Reader boots up looking for a DHCP server. If no DHCP server is found it will
ThingMagic IZAR User Guide
|
26
negotiate a Link-local address with your PC and any other devices on the network. Optionally, you can have the
rea
der use a static a
ddress as a primary or fallback instead of a link-local address.
DHCP will automatically provide the Reader's IP address, subnet mask, default gateway, NTP Server, and DNS
(Domain Name Service)
server. It will also establish a hostname and provide it to the DNS Server. During the
initial boot sequence, if the Reader does not get a DHCP-assigned IP address, a link-local address will be
negotiated with any connected device(s). However, the Reader will periodically check to see if a DHCP server is
available. See the “Troubleshooting Table” for assistance determining the IP address if you cannot access the
reader using the URL hostname.
The following section explains how to set up your PC and Reader on a network.
7.1 Setting Up the Network Hardware
Whether you use DHCP, link-local, or static network addressing, make sure that the network is connected
before powering up the Reader. With default settings, if the Reader does not automatically get the address from
a DHCP server, a link-local address will be negotiated with the local network. DHCP addressing can only be
used as a primary method. Either static or link-local addressing can be used as a primary method or as a
fallback method if DHCP address assignment is unavailable. Neither static nor Link-local addressing can be
used as a fallback method for the other.
Before setting up your network:
Connect one end of an Ethernet cable to the Reader and the other end to an Ethernet switch or
hub.
Check that all antennas are securely connected, and then power-up the Reader.
Connect your PC to the same network as that of the Reader.
NOTE: Some older 10baseT network hubs may not work properly with the Reader. If you encounter
connectivity problems, we recommend using nothing below 10/100baseT hubs/switches.
7.1.1.1 Using Power over Ethernet (PoE)
Another desirable way of powering up the IZAR Reader is to use a single Ethernet cable that is both a
communication link and a power source, called Power over Ethernet (POE).
Power must either be input with
the Ethernet signal compliant with IEEE 802.11AF (POE or POEplus), or via a dedicated DC input port
that accepts 9 to 30 VDC input.
Contact RFID-support@jadaktech for recommendations of PoE adapters that
we have tested successfully with the IZAR Reader.
Do not use POE and DC power at the same time. If making a change, always disconnect one
before introducing the other.
7.2 Using DHCP
7.2.1.1 IZAR Setup
DHCP addressing can be used with any LAN interface. To enable DHCP, follow these steps:
1.
Click on Settings icon at the top of the Web Interface navigation menu to access the Settings Page.
2.
Select Use DHCP = Yes radio button under the General Network Settings section of the Settings
screen.
3.
Click the Save Network Settings button at the bottom of the page.

10.
Click OK, in the Local Area Connection Properties window.
11.
Click OK, in the Local Area Connection Status window. The PC may take few minutes to save the new
network settings.
Automatic Hostname: IZAR-xxxxxx
At startup, the Reader, by default, generates an 'automatic hostname' by appending the last three bytes of its
MAC address to its hostname, such as IZAR-210027. (A label on the IZAR Reader will also provide this default
hostname.)
(From Ethernet Interface page)
Your network must have properly configured DNS servers if you are accessing the reader via its hostname.
When using DHCP, the DHCP server automatically adds the hostname to the DNS server's database.
ThingMagic IZAR User Guide
|
29
NOTE: The hostname can also become known to your PC via MDNS. If you cannot reach the reader via the
hostname alone, append “.local” to the end for the connection to succeed. i.e. IZAR-21071f.local. This is typical
when Link Local addressing is being used.
7.2.1.3 Accessing the Reader via Hostname
The first six characters of the MAC address are the manufacturer's code. The last six characters of the MAC
address are specific to the Reader and are used for automatic hostname addressing.
To log on to the Reader using the Hostname:
Obtain the Reader's hostname, launch your web browser, and then log on to the Reader by entering its
hostname in the address bar, such as http://IZAR-xxxxxx (the last six characters of the Reader's MAC address).
1.
Press Enter. The Reader's Login dialog box appears.
2.
Enter the following:
User name: web
Password: radio
3.
Click OK. The Reader displays the IZAR Status Page.

8 Connecting to the USB Console Port
IZAR supports communication over its USB Console as a serial TTY port to enable you to accomplish the
following:
Access the boot logs as files
Access the console for emergency recovery
Learn the IP addresses of all LAN interfaces
Unlike previous generations of ThingMagic readers, the IZAR console is not active from the beginning of
boot-up. It is only active after boot-up. The boot-up messages may be obtained from log files at that time.
Before you connect to the USB Console port, ensure that you have:
A PC with a USB port
A serial terminal program (such as PuTTY for Windows or CoolTerm for the Mac)
A USB cable (with USB Mini-B plug)
USB Serial Driver. See Section 8.1.1 USB Serial Driver
To address the port correctly, you must determine the port name used by the host OS. On Windows it will be
assigned “COM” followed by a number. For a MacOSX system, the port name will be
“/dev/tty.usbmodem1a123” or similar. For Linux based systems will see it as “/dev/ttyACM0” or similar.
When you have completed setting up the serial port, you must set the following four parameters to allow the
terminal program to talk to the Reader:
Data Rate: 115200
Parity: None
Data Bits: 8
Stop Bits: 1
The procedure for connecting to a specific port is different for each terminal emulation program. Check the
documentation for your program for information on setting these parameters.
Once you have set up the USB connection, press <Enter> to send a carriage return character to the reader.
You should see a printout of the IP addresses, followed by a login prompt.

USB Serial Driver
The console port requires the host have a Gadget serial virtual COM port drivers installed. When the USB port
is connected to a PC, it appears to the PC as a USB memory device with the name, “TMREADER”.
The Gadget serial virtual COM port drivers are in this directory. If signed drivers are needed, they will be in the
new “Windows 10_1607” directory. When the Gadget driver is installed, the USB port will appear

9 Using GPIO
The IZAR Reader includes a 12-pin terminal block connector for GPIO access.
GPIO Connector on the reader:
Molex 0039301120
Mating Connector
Molex 0039012125
Crimp Pins
The crimp pins you wll need for the mating connector are Molex 0039000073 (for 18-24AWG wire), or
equivalent that is appropriate for your wire size.
The GPIO consists of 4 lines of general purpose output, and 4 lines of general purpose input. These lines are
writeable and readable by user programs running on the IZAR. This is a 12-pin connector. The values of the
GPIO lines can be Get and Set using the MercuryAPI. See the respective guide for more details on software
control of these signals.

The four opto-isolated inputs support the following input levels:
V-low (Logic 0) = 0-0.8V
V-high (Logic 1) = 3-30V
5mA max current with 24V input
It is recommended that external devices guarantee a minimum pulse width of at least 100ms.
9.4 Outputs
The four opto-isolated outputs support power sourcing, up to +30V with current sink up to 200mA,
through an external power supply connected between V-GPO and ISO-GND (pins 2 and 7).
Using the MercuryAPI the output signals (see note under Connector Pinout for enumeration values) can
be set as follows:
gpoSet(GPIO_#, 0) sets pin corresponding to GPIO enumeration to Vhigh through 10kohm pull
up resistor to V-GPO.
gpoSet(GPIO_#, 1) sets pin corresponding to GPIO enumeration to Vlow through effective short
(through isolated FET switch) to ISO-GND.
ThingMagic IZAR User Guide

37
All outputs have an active pull down to ISO-GND.
NOTE: For non-isolated applications connect grounds together (pin 7 and 8) and V -GPO to IZAR +5V
(pins 2 and 1). With this configuration the reader provides the +5V supply and can sink up to 200mA, total.
For convenience, the schematic diagram of the GPIO circuits of the IZAR Reader are shown in Figure 23
through Figure 25 so you can more easily determine the external connections that will work for your
application.

10 Controlling the Reader
The Reader uses RFID (Radio Frequency Identification) technology to read and write data stored on RFID
Tag(s). The IZAR Reader provides three levels of access to control read/write operations of RFID tag(s):
1.
Using the Browser-Based Interface:
A web browser controls high-level Reader operations. See Status Page for information about how to
access the browser-based interface.
2.
An application accessing the reader via MercuryAPI on a host, such as Universal Reader Assistant for
Windows PCs:
See the MercuryAPI Programmers Guide and the Universal Reader Assistant User Guide at
www.jadaktech.com.
3.
Directly address the reader from a host application via its LLRP protocol.
EPC global ratified protocol used for communication between the IZAR and a client application. The
IZAR should be “drop-in compatible” with systems supporting the standard LLRP protocol.
10.1 Using the Browser-Based Interface
The IZAR Reader browser-based interface communicates directly with the RFID Reader. It includes several
tools that enable you to monitor Reader performance, change Reader settings, and upgrade Reader firmware.
You can run the browser-based interface from any PC on the network. Carefully configure the PC with an IP
address and subnet mask compatible with the current operational settings of the Reader.
The Reader navigation menu provides access to the following pages:
Status Page – Displays the current operational settings
Settings Page – Allows the user to modify Reader configuration and network settings
Read Page – Allows the user to read on all configured antennas using the configured setting
Firmware Upgrade Utility – Upgrades the tag Reader with new firmware images provided by JADAK
Diagnostics Page – Provides current operating settings and access to the log files kept by the Reader
To start the browser-based interface:
1.
Exit all Reader applications on the network.
WARNING – Only one application may actively control the reader at any time. If a host is
already connected to the reader, you may view status and change configurations values, but
not read tags. Configuration changes made through one interface may not be displayed on the
other interface. A good rule of thumb is that the saved web interface changes become default
values that are used on start-up and, at the time the change is made, the current value.
Changes made through the LLRP interface override the values in current use, but are
temporary and only last until the reader is rebooted.
2.
Type the host name or IP address of the Reader to which you want to communicate in the address field
of the browser. The log-in dialog appears.
3.
Enter the following:
User name: “web”
Password: “radio” (all lower-case).
4.
Click OK. A navigation menu and the Status page appear in the browser, as shown in the Figure 16.

10.1.1.1 Status Page
The IZAR Status Page, as shown in
Figure 26: Status Page
, indicates the reader status, reader version and
current LAN configuration parameters.
Figure 26: Status Page
10.1.1.2 Settings Page
The IZAR Settings Page (
Figure 27: Settings Page
) enables you to change network, performance and security
settings. The page is divided into four main sections:
Reader (Power) Settings
(Gen2) Protocol Settings
Network Settings
Miscellaneous Settings
Changing these parameters may change the settings the Reader uses on startup. Be careful to use correct
values or you may not be able to connect to the Reader without reconfiguring the reader via the console
interface.
NOTE: All settings set through the Web UI | Settings pages are persistent, they are retained across reboots and
become the default settings of the reader for client applications. The values shown on these pages do not
necessarily reflect the active settings of the Reader if configuration parameters are transiently changed through
the MercuryAPI or LLRP. All changes made through MercuryAPI or LLRP client applications are transient. The
reader will return to its last saved persistent settings (“default settings”) if rebooted.
NOTE: Do not disconnect power until the save process is complete. Unless stated otherwise in the release
notes, all new RFID, network and security settings take effect after saving.

10.1.1.11 Firmware Upgrade Utility
IZAR provides the Firmware Upgrade Utility for loading new firmware onto the reader. A single ".tmfw"
upload file will have name such as:
tmreader-5.3.0.126.tmfw
Reboot the reader after installing this file. (Your previous firmware will remain active until you do.)
In some cases, firmware might be distributed as several ".deb" files. Here are the typical files that
comprise a complete set:
tmapp-5.3.0.126.deb
tmreader-core-5.3.0.126.deb
tmrfid-5.3.0.126.deb
tmsafe-5.3.0.126.deb
tmweb-5.3.0.126.deb
Usually order of installation of the individual files does not matter and the reader need only be rebooted
after all files are uploaded. (Not all individually updated file versions will appear in the Status screen until
the reader is rebooted.)
NOTE –
The “Revert to default settings” button on this browser page can also be used to reset the reader

The time the tag was read. For accurate time an NTP server should be configured.
Tag Data
When reading an embedded TagOp is specified for a Read- Plan the TagReadData
can contain up to 128 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 (0
°
-180
°
)
LQI/RSSI
The receive signal strength of the tag response in dBm.
For timed (synchronous or pseudo-asynchronous) reads, the information will apply to the first time this tag
was read (or optionally, for the read with the highest RSSI) with a tag count that represents the number of
times this tag responded during the read cycle.
For asynchronous (continuous) reading, a new record with appropriate meta data will be generated each
time the tag responds so the read count will always be ʻ1”.

11 Reader RF Power
During initial installation, the reader must be properly configured to use the correct RF power to comply
with FCC or other regional regulations. DO NOT increase the power beyond this level.
The IZAR supports separate read and write power level which are command adjustable via the
MercuryAPI. Power levels must be between:
Minimum RF Power = 0 dBm
Maximum RF Power = +31.5 dBm
Power Settings for Authorized Antennas and Cables
This device has been designed to operate with the antennas listed in Authorized Antennas list using the
cables in the 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 more information about setting the RF power, refer to Setting the Reader RF Power.
NOTE: Be sure to read Compliance and IP Notices to maintain compliance with FCC or other applicable
regional regulations.
11.1 Setting the Reader RF Power
To set the Reader RF power:
1.
Log on to the Reader using your browser.
2.
The IZAR Status Page appears, as shown in the Figure 16.
3.
Click on the Settings icon. Click on the “Reader” header. By default, the value for RF output power
is 31.5 dBm for all functions, on all antennas.
4.
Enter the maximum setting based on your cable type, length, and antenna type.
5.
Scroll down to the bottom of the screen and click Save changes button.
The Settings Page will reload automatically after the settings have been saved.
Optionally, the RF power may be set at a different level for read operations than for write operations or at a
different level per antenna.

12 Thermal Considerations
When transmitting at its highest RF power levels, the enclosure temperature of the IZAR Reader will rise.
Industry guidelines do not consider any surfaces whose temperature is above 70 C to be safe to touch. If
the IZAR Reader is operated at elevated ambient temperatures, care should be taken that it is mounted to
conductive material to limit how high the temperature of the enclosure rises.
13 Mounting the Reader
See Appendix B: IZAR Dimensions for mounting hole locations and dimensions.
CAUTION!
If there is any chance of dust or water exposure, the IZAR should be
mounted in an appropriate water-tight enclosure.
13.1 Ceiling or Wall
Follow these steps to mount the reader on a ceiling or wall:
1.
Hold the reader in its mounting location and mark the position of the four mounting screws.
2.
Drill holes for the screws and install wall or ceiling anchors if required. For ceiling mount, use only
anchors specifically designed for ceilings.
3.
Hold reader over holes and insert the screws and tighten until almost flush with the wall.
4.
Tighten the screws.
13.2 Variables Affecting Performance
Reader performance may be affected by the following variables, depending on the site where your Reader
is being deployed:
Environmental
Tag Considerations
Multiple Readers
13.3 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.
ThingMagic IZAR User Guide
|
53
Moving machinery can interfere 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, then 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 up.
WARNING!
The IZAR 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 IZAR 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.
13.4 Tag Considerations
There are several variables associated with tags that can affect Reader performance:
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 antenna is circularly polarized, so it reads face-to but not edge-to.
Tag Model: Many tag models are available. Each model has its own
performance
characteristics.
13.5 Multiple Readers
The Reader adversely affect 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.
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 time-multiplexing strategy.
Antenna power can be reduced by reconfiguring the RF Transmit Power setting for the Reader.
Low read rate settings (high Tari value, low BLF value, high “M” value) will reduce channel-to-channel
interference
NOTE:
Performance tests conducted under typical operating conditions at your site are recommended to
help optimize system performance.

14 IZAR Specifications
The following are the specifications for the IZAR Reader.
14.1 UHF RFID Antenna Interface
Interface: Four RP-TNC Connectors
RF Power Output: Separate read and write levels, adjustable from 0 dBm to 31.5 dBm (1.4 W)
Frequency: Hop table with up to 62 entries, configurable in 50KHz steps, accommodating the following
ranges (hardware dependent):
– 902-928 MHz (FCC; NA, SA)
– 865.6-867.6 MHz (ETSI; EU)
– 865-867 MHz (MCIT; India)
14.2 Power
If designing a power source for the IZAR Reader, use the worst-case maximum power consumption
figures. If estimating battery life for a power source connected to the IZAR Reader, use the typical figures.
Both are provided below. Note that external devices connected to the IZAR Reader can impact the power
consumption
External DC Power: 9 to 30 VDC supply voltage. Maximum DC power under all worst case conditions: 17
W. This is based on 13 W being consumed by the IZAR Reader itself and 5 W being supplied to external
peripherals that are connected to the IZAR Reader. It is recommended that DC supplies connected to the
IZAR Reader be capable of supplying 17 W to avoid a brown-out condition under any circumstances.
Neglecting external peripheral circuitry being powered by the IZAR Reader, typical maximum DC power
consumption when transmitting at +31.5 dBm is 13.0 W into an approved antenna.
If power is being drawn from the host USB port, add as much as 2.5 W to the typical power consumption
when transmitting or at idle. If power is being supplied by the 5V GPIO power source, add as much as 2.5
W to the typical power consumption to account for this. Therefore, the typical power consumption when
transmitting will vary between 13 and 17 W depending on how the IZAR Reader is used.
NOTE:
If a third-party DC Power supply is used it must meet the following criteria:
Be UL Listed
Meet the above operating specs
The output must comply with SELV and LPS characteristics
Have a maximum operating ambient temperature that meets or exceeds the intended IZAR operating
temperatures as covered under the UL Listing of the power supply.

Note on SafeMode
:
The IZAR status LED also toggles red/green every 250ms while in safe mode
IZAR safe mode causes the “safe web page” to run on the normal web port (80), as well as its
usual 8888. The idea is that if the regular web interface is damaged, this allows the “safe” one to
take over.
19.3 Safe Mode
If the standard web interface should become corrupted such that the reader firmware cannot be updated,
a backup web page is available. It is accessed the same as the standard web page, but with a port
number of “8888”. To do this, you add “:8888” after the IZAR host name or IP address of the URL you are
accessing. For example, http://10.8.80.61:8888/firmware or http://IZAR-b65b2f:8888/firmware. You will be
presented with the login prompt again. The only screen available will be the one for updating firmware.
