4 Hardware Overview
4.1 Ports and Connectors
4.1.1.1 Antenna Connections
The Sargas supports two monostatic bidirectional RF antennas through two Reverse Polarity SMA (abbreviated
to “RP-SMA”) connectors: labeled ANT1 and ANT2 on the Sargas - Figure 9.
The maximum RF power that can be delivered to a 50 ohm load from the external port is 1.0 Watts,(+30.0
dBm). Depending on the antenna used and the localregulations for your region of operation, the maximum
permitted levelmay 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 manytimes per second, oftenresulting in the appearance of continuous reading on both antennas.
4.1.2 Figure 9: Sargas RFID Antenna Ports
Antenna Requirements
The performance of the Sargas is affected by antenna quality. Antennas that provide good 50 ohm match at the
operating frequency band performbest. 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 dBreturn 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 Sargas
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 22 cm is maintained between
the radiator (antenna) & 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.

ThingMagic Sargas User Guide | 17
5 Programming Interfaces
5.1 Mercury API
Applications tocontrol the Sargas 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 demoing and developing functionality. For more information on the MercuryAPI
see the MercuryAPI Programmers Guide and the MercuryAPI SDK,available on the ThingMagicwebsite.
5.2 Demo Applications
As the starting pointfor learning the capabilities of the Sargas 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 rfid.thingmagic.com/devkit) under
/cs/samples/exe/. See the Universal-Reader- Assistant User Guide (available from
http://www.thingmagic.com/manuals-firmware) 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 Sargas and a client application. The Sargas 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 Sargas. 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 theseextensions in XML format.
For more information on direct use of LLRP, the ThingMagic custom extensions and the open sourceLLRP
Toolkit please contact ThingMagic support ([e-mail]).
5.4 On-Reader Applications
The Sargas supports running custom applications on the reader, builtusing 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 maybe downloaded
from http://www.thingmagic.com/manuals-firmware.

ThingMagic Sargas User Guide | 18
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

The additional hardware required includes:
A computer with a webbrowser
Ethernet cable (CAT5e; shielded is recommended)
Antenna(s) which are tuned for the frequency range of operation.
Coax cable(s) (one end must be adapted to the RP-SMA connector on the Sargas reader)
Optionally, you should have a USB cable (PC type A connector to Sargas mini- USB
connector) in case console access is required.
Note
To initiate tag reading with the Sargas Reader, no host software is required aside from a browser.
Toset 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 Sargas Reader are contained in the following sections:
4.Connecting Antenna(s) to the Reader
5.Powering Up the Reader
6.Connecting Your PC to the Reader
7. Communicating with the Reader using a Link-local Address
8. Logging On to the Reader
In this procedure, various interfaces will be described. They are shown in Figure 11. Networking Settings
6.2.1 Figure 11: Sargas Reader Interfaces

ThingMagic Sargas User Guide | 19
6.2.1.1 Connecting Antenna(s) to the Reader
The Sargas Reader supports up to two monostaticantennas. The default power setting is a convenient way to
set the power of both 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: Sargas
Antenna and Cable Information.
6.2.1.2 Powering Up the Reader
Power up the Sargas using a DC power supply - NOTE: Sold separately to power up the Sargas Reader using
a DC power supply:
1. Plug the power supply into the Reader's DC power input connector.
2.Connect the extensioncord 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 left (red) RFID status led will be on. The Reader is ready for operation after approximately 60
seconds when the right (green) LED is illuminated and the red LED goes off.
6.2.1.3 Interpreting the Reader Indicator LEDs
The Sargas Reader has two operational status LEDs, near the DC power connector, which allow you to
determine the current operational readiness and activity of the Sargas Reader.
The colors displayed by the LED include:
Red LED on Indicates that the Reader is starting up.
Red LED blinking: Reader is attempting to obtain an IP address using the default or configured
methods.
Green LED on: Indicates that the Reader has a valid IP address and is ready for operation.
Green LED blinking: Indicates that the RF field is ON and the unit is attempting to read tags.
Additionally, when the Reader is connected to a PC or a network outlet, the two small LEDs adjacent to the
Ethernet (LAN) port indicate Network Status and Network Activity.
6.2.1.4 Connecting Your PC to the Reader
Network connectivity to theSargas Reader is provided via its LAN port.For instructions on connecting the
Reader to a network, see the sectionNetworking Settings.
When connected directly to a PC, 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 negotiatea valid
IP address.
Toconnect 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 port.
6.2.1.5 Communicating with the Reader using a Link-local Address
If you are using an operatingsystem 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 thisis the default configuration:
1. Select Start from the Start bar, and then select Control Panel.
