Set up

The following procedure outlines the steps to hook up UHF RFID Reader.

1- Connect UHF antennas, Ethernet Connector, 5 decibel Wi-Fi antenna and other input/output

devices, if any, to their associate connectors on the reader.

2- Plug in the DC adaptor to UHF RFID Reader’s power socket. It takes about 30 seconds for UHF RFID

Reader to load completely. Meanwhile, all LEDs show a chasing effect, announcing that the device

is booting.

3- When UHF RFID Reader loads completely, the Power LED changes to solid light and you will hear a

double beep.

4- If the boot process fails due to any reasons, UHF RFID Reader makes 5 long beeps.

5- Restate UHF RFID Reader to its default factory settings.

6- After the device boots successfully, Power and Status (Network) LEDs illuminate. You will also hear

a double beep.

7- If you hear 5 short beeps, there is definitely a hardware problem with the device or its

connections. Check troubleshooting for more information.

It is highly recommended that you get done with all hardware connections

before powering UHF RFID Reader up. Failure to do so, your device may be

damaged due to voltage fluctuations.

UHF RFID Reader is by default in Access Point mode with its SSID in this format:

“RSWR-400_XXXXXX” and no password is needed.

UHF RFID Reader is by default in Access Point mode, you can connect to it via Wi-Fi

or Ethernet connection.

Page 17

Settings

In this page, user can set UHF RFID Reader’s time and working mode, Figure 7. UHF RFID Reader works in

two different modes; Reader and Anti-Theft. Each mode has its own capabilities and thus specific

configuration settings. We will delineate the specific features of each mode in this sections.

Figure 7, UHF RFID Reader Settings Page

Reader Mode

In this mode, UHF RFID Reader works like a server and waits for clients to connect to it. For example

suppose that you have an inventory management software in your store which is already working with

barcode. You may want to elevate your current system to work with RFID. To achieve this goal, your

current software should connect to UHF RFID Reader as a client. UHF RFID Reader acts as a pathway

between inventory software and RFID tags. In Reader mode, user should select one of the following

options;

 LLRP

 Radiant Sensors API

LLRP Reading

In this mode UHF RFID Reader reads RFID tags and sends their EPC to a host as while as they are in-range. It

means that EPC of a tag may be sent to the host over and over. The protocol used in this mode to exchange

data between UHF RFID Reader and the host is LLRP. In LLRP Reading mode, UHF RFID Reader supports just

one client at each time, excess clients are rejected automatically.

If you select Save Bandwidth checkbox, UHF RFID Reader will filter duplicate tags; in the other word, UHF

RFID Reader sends duplicate RFID tags each 5 seconds by default. This leads to a drastic cut down in

network traffic which in turn results in much more effective use of bandwidth.

UHF RFID READER

Page 18

Radiant Sensors API

Radiant Sensors API mode entirely looks like LLRP Reading mode in its functionality. The difference is just in

its implementation. In this mode communication occurs according to Radian Sensors protocol.

In Radiant Sensors API mode UHF RFID Reader supports up to 10 clients simultaneously, excess clients are

rejected automatically.

Anti-Theft Mode

This mode, as the name implies, is used to prevent unauthorized removal of tagged items. UHF RFID Reader

has three paradigms to approach the task. When selects Anti-Theft mode, user can see the following

options, Figure 8;

 Anti-Theft

 Anti-Theft with stray tag filtering

 Anti-Theft with port 3 & 4 stray tag filtering

Anti-Theft

In this mode UHF RFID Reader makes an alarm whenever reads a tag. UHF RFID Reader is commonly

installed at the exit to warn leaving of any items. Depending on the required reading rate and scan range,

any combinations of four UHF antennas may be used in this mode.

Anti-Theft with Stray Tag Filtering

When boots completely, UHF RFID Reader starts appending all in-range tags to an Ignore List for 60

seconds, this time interval is called Learning Time. After the 60th second, two situations may arise;

1- Some tags show up in the read range of UHF antennas and stay there for more than 5 seconds, in

this situation the tag is added to the ignore list.

2- Some tags show up in the read range of UHF antennas and leave it before the 5th second, in this

situation UHF RFID Reader gives rise to an alarm.

Anti-Theft with Port 3 & 4 Stray Tag Filtering

In this mode UHF antennas are divided into two groups; 1, 2 and 3, 4. After booting, antennas 3 and 4 start

appending all in-range tags to the Ignore List for 60 seconds (Learning Time). After the Learning Time, two

situation may come up;

1. Some tags may leave the reading range of antennas 3 & 4 and remain out-of-range for more than

Ignore Time (Refer to Action section). These tags are removed from Ignore List.

2. Some tags may leave the reading range of antennas 3 & 4, remain out-of-range for more than

Ignore Time (Refer to Action section) and show up in the reading range of antenna 1 & 2. These

tags are known as theft ones and bring about an alarm.

Regardless of the selected mode, user has to set some parameters to put UHF RFID Reader in Anti-Theft

mode.

Matching Condition

As a preamble for this section, it is reminded that each code number on RFID tags is composed of 2 parts;

16 bits long PC and 96 bits long EPC, the abbreviation for Product Code and Electronic Product Code

respectively, Figure 9. The code is represented in hex, and each group of digits act for something. For

The Region field must be filled in accordance with the country/region of

operation to comply with local laws and regulations. The user is responsible to

confirm operation with the correct RF settings and are solely responsible for any

fines and other damages due to incorrect or non-compliant country/region

settings on your Reader.

UHF RFID Reader may be damaged if you don’t connect antenna to a port and try

to send data to that port!

of the EPC. For more information about RFID tags refer to Related Documents section.

EPC

Figure 9, RFID Code Number

It was mentioned earlier that the most prominent feature of Anti-Theft mode is that, in this mode the

system can distinguish the sold items from unsold ones. To achieve this goal, the seller changes some bits

of code number to a predefined pattern when they sell an item. At the exit, those bits are checked to

match with the pattern. If not, the system alarms. A filter with three parameters is designed to check the

leaving tags.

Filter Start Bit

This parameter determines index of the bit that the filter will start from. Actually we specify the bit

position, which the seller starts changing from, when the item is sold. For example if you set this bit to 0, it

begins from the first bit of PC, and if you set it to 16, it starts from the first bit of EPC (The 16th bit of the

code), Figure 9.

Filter Length

Specifies the number of bits that the filter will use for pattern matching (64 bits at most). In fact we set out

how many bits change when the item is sold.

Filter Pattern

In this field we determine the pattern that the filter bits must be compared with. When you set the filter

length to 4 for example, a 4 bit pattern must be given to UHF RFID Reader. Hence, four boxes appear on the

page to be filled. You can fill each box by 0, 1 or x. Note that the pattern must be completely different with

tag’s initial code number, unless unsold items are misrecognized as sold.

Examples are better than thousands of words! We end this section with some examples to give a better

understanding of Anti-theft mode.

Example 1

Consider a filter with the following parameters:

Filter Start Bit

Filter Length

Filter Pattern

1001

UHF RFID READER

Page 21

When items are sold, bits 7-10 of their tag number is changed to 1001. At the exit, bits 7, 8, 9 and 10 are

checked to be 1, 0, 0 and 1 respectively. Unless, system alarms!

In the Filter Pattern field, x means don’t care; it is compatible with either 0 or 1. In example 1, if the filter

pattern is 100x, both 1000 and 1001 pass through the filter, i.e. they are allowed to exit!

Example 2

Consider the following filter:

Filter Start Bit

Filter Length

Filter Pattern

The starting bit of the leaving tags is tested to be either 1 or 0. If we configure the system to beep

whenever an item exits, we hear a beep as each tag is read.

This example is an interesting application of using x in filter patterns, when we want to just make sure that

the Reader is reading tags.

Example 3

As a more comprehensive example, suppose that you have 3 tags with their code as Table 7:

There are usually some common digits between codes, the filter is better to be selected from the most

common digits. There are 16 common digits between these tags which can be selected as filter bits. The

maximum length of this filter can be 64 bits (16 hex numbers).

For this example we can set these values:

Filter Start Bit

Filter Length

Filter Pattern

10011001

Bits 16-23 of the leaving tag is checked to comply with 10011001.

If we change the parameters as:

101

Bits 7, 8, 9 of the code number are checked to be equal to 101.
