Purpose
The purpose of this document is to describe the tres900 features, functions and options.
Included in this document will be details on the installation, the operations and any other
special considerations necessary to setup and operate the product.
Summary
tres900 is the brand name for a new line of 902~928 MHz RFID Readers and Tags. We are a
U.S. company comprised of seasoned RFID professionals, including engineers, marketing, and
distribution specialists. We have co-designed a product line that is ideally suited to the supply
chain, document tracking, and parking markets. We will be selling our products through
Systems Integrators and OEM channels.
RFID systems provide an automatic means to identify physical objects without the need for
line-of-sight communication. The main components of a RFID system are tags, readers, and
host computer. RFID tags are attached to physical objects as a means to identify them. RFID
readers convert the radio waves sent from the tags to get the digital data and send the collected
data to the host computer.
ProductIdentification
To identify the tres900 newly developed 902~928MHz Passive Tag, Reader, Wiegand +
RS232 Serial IO outputted simultaneously and a TCP/IP Ethernet + RS232 serial IO outputted
simultaneously version, the shipping label is marked with the complete model part number and
final assembly number. Detail ordering is described later in this document.

ProductOperations
HardwareDescription
The tres900 Reader comes with many rich features like multi-protocol and multi-tag reading,
integrated and environmentally protected packaging, long-distance reading and writing, and the
ability of reading multiple tags moving at high speed.
The tres900 Reader is a fully integrated reader with a RF module, digital signal processing
(DSP) module, power conditioning module, built-in circular polarized antenna and packaged in
a weather-proof and UV protected housing. The circular polarized antenna allows it to work in
asset management applications and its programmable triggering modes enable the reader to
work in either self-triggering or master/slave modes. Versatile I/O interfaces enable the tres900
to work with serial RS-232, Wiegand, and TCP/IP Ethernet.
The tres900 Reader is a multi-protocol UHF reader, which supports ISO18000-6B and EPC
protocols. It can read and write UCODE, TI, Alien and many other labels. The reader’s
firmware is upgradable, enabling it to support protocol expansion and feature upgrades, giving
it the ability to grow with the maturing RFID technologies.
The integrated high-gain and circular polarized antenna allows the reader to achieve a
respectable read range, and the internal DSP module enables the reader to manage multi-tag
arbitration at high speed, thus making it suitable for material management applications.
Reader
The RFID Reader is a device that captures and processes tag data. These devices are called
readers or interrogators. Readers are connected to the antenna and are connected to the RFID
network infrastructure. The Reader provides the energy of which a fraction is used to energize
and wake up the tag. The reach of the reader is determined by the design of the antenna (both
Tag and Reader) and the power and configuration of the reader. The Reader detects and filters
data bits emitted from compatible RF Tags then converts the bits into the associated computer
format of serial RS232, Wiegand, and/or TCP/IP Ethernet communications protocols.
Advanced error detection algorithms provide error-free operation.
The Reader can also operate on variable power sources of 8 to 16 VDC. Connection to the
Reader is made using low-cost shielded twisted pair cables (22 AWG up to 22 feet, over 22 feet
see recommended wire chart at end of this document).
Tags
An RFID-tag is a device which is attached to objects and/or assets to be identified. When radio
signals are received, information is transmitted back to the RFID reader. RFID tags consist of
the following components: the microchip (or IC), the antenna, the connection between IC and
antenna and the substrate on which the tag is produced. The microchips are the brains of the
tag. The antenna handles the communication from either the Tag to the Reader or from the
Reader to the Tag.
Passive tags reflect the RF signal transmitted to them from a reader or transceiver and add
information by modulating the reflected signal. A passive tag does not use a battery to boost the
energy of the reflected signal.

ReaderInstallationGuide
This section contains information for configuring the Reader’s power and signal cabling. Power
and communications are provided through a supplied pigtail cable at the bottom of the Reader.
Mounting
The mounting bracket is designed specifically for mounting the tres900 Reader. The Reader
could be installed on a pole or on wood, concrete, or brick structures and aim the antenna

toward zone of coverage. Figure 7 below shows how the bracket looks assembled on a pole.
The tool of choice would be a 3/8” (10 cm) wrench.
Figure 7
InstallationOverview
The Reader is supplied in a weatherproof enclosure for direct outdoor installation or can be
placed indoors, such as in a guardhouse, or close to other electronic equipment. The Reader
outputs the decoded ASCII data to an access control unit via standard data cabling. Systems are
available that output data in both the standard Wiegand and serial RS232 outputted
simultaneously and/or the TCP/IP Ethernet and serial RS232 outputted simultaneously.
TriggerFunction
If the Reader is configured for triggering mode, the reader will only read a tag when the BLUE
trigger wire (T1) is tied to ground. Normal ways to accomplish this is by using Loop Detectors
to detect the presence of a vehicle to open a gate, or as a safety device to prevent the gate from
closing on a vehicle in its path.
VerticalPlane
Vertical orientation is adjusted so as to aim the antenna at a spot about twenty feet (6.5 M) on
the road from the vehicle. From this spot forward, the detection area will increase as you get
closer to the gate.
TagVehicleInstallation
A vertical orientation is the optimal orientation of the Tag in order of signal response
performance. If not a windshield tag, then install the Tag using double-sided tape or Velcro™.
Ensure the label-end of the Transponder is mounted in a vertical position for optimum read
range. Prior to installation, make certain the desired location complies with all state and local
vehicle code laws.
ParallelSurfacesRule
Passive RF tag actually gets its’ power from the reader. That is to say that, the reader is
emitting RF and the tag must be able to absorb that RF, accelerate the signal and to reflect it

back to the reader. Therefore, if the surface of the reader and tag are close to parallel, this
principal will result in better tag reads.

TroubleshootingGuide
Q: To confirm that the unit is operating properly
Confirm the beeper is audible when a good tag is presented or when power is first applied. If it is
not, remove power.
Check that the RED and BLACK wires are installed correctly
Check the voltage at the Reader pigtail cable (see wire chart below), if you under cabled the
voltage drop would be too much to power up the Reader. Verify the voltage supplied to the
Reader is between 8 and 16 VDC
Q: Reader just beeps and keeps beeping, about 3 x per second
Not enough power from the power supplier, Insufficient power,

Check the voltage at the Reader pigtail cable (see wire chart below), if you under cabled the
voltage drop would be too much to power up the Reader. Verify the voltage supplied to the
Reader is between 8 and 16 VDC
Q: Reader does not recognize a tag (no beep, no outputted tag data)
If no beep, check to see if another tag works, maybe damaged tag. Verify Reader operations by
connecting to a computer through the RS232 port and running a Terminal program.
Q: How can I verify that the tres900 Reader I have is Wiegand or serial or TCP/IP?
Both Reader products have RS232 and one model has Wiegand and one has TCP/IP. The TCP/IP
model has a cat 5 cable with an 8 pin connector attached.
Q: Tag data to panel is scrambled or Reader beeping and host not responding
One or more of the Reader’s wiring connections are incorrect. Power down the receiver/panel and
verify the wiring connections are correct. Check that Data 0 (GREEN wire), Data 1 (YELLOW
wire) and ground (GRAY) are properly attached between the tres900 to the host panel.
Earth Ground should terminate at the back of the Reader through the mounting brackets or
through the Readers Power Supply Ground wire (negative feed).
Cable between Reader and panel is too long, check Wiegand specifications
Check to insure the tres900 tag number and site code are properly programmed in the host panel.
Check the Wiegand timing that your host is looking for and insure their timing scheme is within
the SIA standard parameters.
Q: Read Range too short
Ground loop could be an issue here, see if earth ground terminates at the reader. Check by
powering reader without reader ground wire connected. Earth ground should terminate at the
Reader, check your panel or power supply.
Tag orientation should be in a vertical position for the Readers Antenna maximum performance
and distance.
WiringGuide
Selecting the correct size and type of wire will enhance the performance and reliability of your
system. The size of the wire must be large enough to carry the maximum current expected
without undue voltage losses. All wire has a certain amount of resistance to the flow of current.
This resistance causes a drop in the voltage from the source to the load. Voltage drops cause
inefficiencies. The wire sizing guide below provides the minimum wire size needed to limit
voltage drops to 5% at a given distance in a 12V system.
