Introduction
1.1
What Products are Covered by this Manual
This manual covers the DataReader (both Indoor and Outdoor versions),
DataSeal, DataT ag and the MagneticDataSeal products.
The DataTerminal, DataPort, MicroDataReader, T rackingDataReader and
SmartDataReader are Hi-G-T ek products that are referred to in some places
in the manual, but are not covered by it.
1.2
About the Product
Thank you for choosing Hi-G-T ek quality products. The Hi-G-T ek range of
products provides a highly reliable and secure cargo and asset monitoring
system utilizing state-of-the-art RFID technologies.
Cost-effective, more reliable and more secure than their mechanical
counterparts, the Hi-G-T ek product range will constantly monitor your
assets and alert you to any potential problems at all times.
The Hi-G-Tek system was developed in order to fill the requirement for
fast, automatic processing of secured cargoes and to provide real time
monitoring and improved management of cargoes both in transit and in
storage.
The basis of the system is a family of reusable electronic seals named
DataSeal. This family of products includes the DataSeal, DataT ag and the
MagneticDataSeal.

Hi-G-Tek Ltd. Microelectronics & Asset Tracking Technology
Chapter 1
Introduction
Note : T his manual uses the term DataSeal to refer to any member of this
family of products, unless otherwise specified.
The most significant purposes of the DataSeal are:
Track any attempts of opening, bypassing or tampering.
Record events when tamper occurs.
Write and read user data.
The reusable electronic seal automates the processing of secured cargoes
enabling the organization to effectively and economically process the
increasing numbers of containers’ traffic in the ports and between inland
destinations.
The DataSeal includes a transmitter / receiver unit, real-time clock,
processor, memory and sensing circuitry for sealing verification. T he
Sealing Wire1 prevents any attempt of opening, bypassing or tampering
with the seal without alerting the system and recording of the event. T he
system combines the technological and operational advantages of both low
frequency close-range AND high frequency (UHF) long range for sealing
verification and other communications with the DataSeal.
The low frequency (short range) communication protocol is used by the
DataTerminal, the DataPort and the MicroDataReader. T his channel of
communication is useful for writing the electronic manifest of the sealed
cargo into the DataSeal's memory. For example: this information can
In the case of DataTag, there's a “ Sensor Plate” instead of the Sealing Wire, and
in the case of the MagneticDataSeal, there's a “ Magnet Element”.

Introduction
include the vehicle ID, container and invoice numbers, cargo description,
etc. It is also useful for reading the DataSeal's event records, and to reset
the DataSeal for a new use (an operation called "Set").
Note : The low frequency protocol, the DataTerminal, DataPort and
MicroDataReader devices are not covered by this manual.
The high frequency protocol is used by devices of the DataReader family of
products. This family includes the DataReader itself, which connects to a
controlling computer (normally a PC) through an RS-232/485 interface; the
TrackingDataReader which contains a GPS and GSM modules and is
usually installed on a truck; and the SmartDataReader which contains an
embedded PC and connects to an Ethernet network. This manual covers
only the DataReader device itself. The high frequency protocol is useful for
monitoring the presence and status of one or more DataSeals constantly or
periodically. It is capable of communicating with multiple DataSeals
simultaneously and even with DataSeals in high speed motion, for
example: on a train.
The DataSeal and DataReader devices are capable of communicating in
distances of up to 30 meters, and in some cases even more.
The use of the high frequency/long range protocol enables applications
such as: tracking and sealing verification of containers in transit; protection
of containers in storage; remote automatic data collection from secured
cargoes as they pass through check points, etc.
The DataReader is able to detect which DataSeals are present in its area,
and their statuses (open/close, tampered, etc). It can also receive messages
from DataSeals in real-time, for example when the DataSeal is tampered.
These types of messages that the DataSeal transmits are called "Burst
Messages".

Introduction
Multiple DataReaders can be connected to a single controlling computer
using the RS-485 interface. This allows to maximize the coverage area of
the DataReaders while keeping them synchronized. The DataReader is
available in both indoor and outdoor models.
A set of Mounting Fixtures has been developed for the DataSeal system
which allow convenient mounting and removal of the DataSeal from a
container whenever required. The various Mounting Fixtures differ in the
level of protection they provide to the DataSeal as may be required in
various environments.

the unit to the RS-232/485 networking cable.
The DataReader may be used in both stationary and mobile configurations.
In the stationary configuration, the unit is mounted on a flat surface such as
a wall or pole. A typical installation of this configuration is at the point of
exit from ports, customs terminals, warehouses, etc. This operation mode
allows monitoring of the DataSeal at predetermined sites and checkpoints.
In the mobile configuration, the unit is mounted in the truck cabin. T he
DataReader monitors the seal during the entire journey, and reports its
status via the vehicle’s communication system to the control center in realtime. T his configuration requires an additional 3rd party controlling device
to control the DataReader, or to use the T rackingDataReader which is not
covered by this manual.

DataReader uses state-of-theart technology to secure and
monitor secured cargoes in
an indoor environment.
The Indoor DataReader may
be use d in
stationary
configuration only.
The unit is mounted on a flat
surface such as a wall or
pole. A typical installation of
this configuration is at the
point of closed warehouses, offices, etc.
Unlike the Outdoor DataReader, the Indoor version does not have the lower

Quick Start
Quick-Start
The aim of this chapter is to lead you step-by-step in the quickest way to
the stage where you can verify that the Demo System is working properly,
and that you have a simple system that you can play with, in order to
evaluate the potential of the products. This guide a ssumes that the
parameters of the DataReader and DataSeal are the factory defaults, and it
refers only to the Demo System. For installation instructions for a
DataReader that is not a Demo System, see chapter 5.
2.1
Before you begin
Before you begin, make sure that you have the following items available:
1. The Hi-G-T ek DataReader device.
2. DataReader Antenna.
3. At least one Hi-G-T ek DataSeal device.
4. The Seal ID of the DataSeal (printed on the sticker on the bottom side
of the DataSeal).
5. Sealing Wire(s) (according to the number of DataSeals. If you are using
DataTags you need Sensor Plate(s) instead of the Sealing Wires)
6. PC running one of the following operating systems:
•
Windows 98 or above.
•
Windows NT 4.0 or above.

computer must use an Intel Pentium TM or compatible processor.
7. CD-ROM with Evaluation Software.
2.2
Setting up the DataReaders
First, connect the antenna to the DataReader. The antenna connects to the
T NC connector at the top side of the DataReader.
Then, connect the DB9 female connector to a serial communication port in
the PC. T ake note of which port you are using (for example COM2). It is
good practice to connect and disconnect cables only when the computer is
off.
Plug the power chord of the DataReader into a power outlet. You should
see the POWER LED blinking red and green. After about 30 seconds it
should remain green. If it remains red, or isn't lit at all, there is a problem
with the DataReader. Refer to the chapter 0 for troubleshooting.
2.3
Installing the Evaluation Softw are
If the computer is not turned on, turn it on now, and wait until the operating
system is loaded completely.
Insert the CD-ROM labeled "Hi-G-T ek" into the CD-ROM drive.
From the Start menu, choose "Run". Assuming your CD-ROM drive is
drive E, type "E:\DataSeal Evaluation Software\Setup.EXE" in the "Run"
dialog box. If your CD-ROM drive letter is not E, replace the first E with

2.5
Preparing the DataSeal/DataTag
DataSeals provided by Hi-G-T ek leave the factory in a special power
saving mode called "Deep Sleep Mode". Before you can communicate
normally with a DataSeal, you must send it a special command called
"Hard Wakeup" that returns the DataSeal into its normal mode of
operation. You will then have to close the Sealing Wire (as will be

explained below), and send another command called "Set" that prepares the
DataSeal for normal operation.
This section describes how to prepare a single DataSeal. If you have more
than one DataSeal, repeat all the instructions in this section for each
DataSeal you have.
In order to send the Hard Wakeup command to the DataSeal or DataSeals
do the following:

Chapter 2
Quick Start
From the Command Code drop down list, select Hard Wakeup.
Copy the Seal ID of the DataSeal you want to wake up into the Seals/Tags
ID text box. The Seal ID is printed on the sticker on the bottom of the
DataSeal.
Click the Command Exe cution button. The mouse cursor will change to
an hourglass icon for about 11.5 seconds and then return to a normal
pointer cursor.
If the DataSeal received the message, The Result box will show the
message "Command OK" in green letters. If not, verify that you typed the
Seal ID correctly in the Seals/Tags ID box, and that the DataSeal is nearby,
and try again. If you still don't get the green "Command OK" message, or
you see a different red message in the Result box, refer to chapter 9 for
troubleshooting.
If you're using a DataSeal (as opposed to a DataTag), you now have to
close the Sealing Wire by inserting its 2 ends to the 2 sockets in the
DataSeal. Push the ends inside the sockets as far as you can. (You should
hear a 'Click' when the wire end is fully inserted). If you're using a
DataTag, you should place the Sensor Plate in its appropriate place at the
bottom of the DataTag.
From the Command Code drop down list, select Set and then click the
Command Exe cution button. After about 4 seconds, a green "Command
OK" message should appear in the Result box.
Congratulations! Now your DataSeal is prepared for normal operation!

Executing a Verify comm and
As a matter of fact, if everything worked fine up to this point, you can be
sure that your Demo System is working. Nevertheless, you probably want
to know how to perform some basic operations.
The most commonly used command is the Verify command. T he main
purpose of this command is to detect which DataSeals are currently around,
and their status (opened/closed, tampered/not tampered).
In order to execute a Verify command, open the Ve rify & Se t window, by
clicking on the

bottom of the window.
A complete explanation about the results you see is out of the scope of this
Quick-Start chapter. Nevertheless, there are 2 flags in the DataSeal's Short
Status that are worth a brief explanation here.
2.7
A Brief Tutorial Through the States of the DataSeal
The DataSeal has many flags that determine its state, as well as Parameters,
Event Records and User Data. Even though most of these features are out
of the scope of this chapter, 2 of the flags represent the most fundamental
concepts of the DataSeal. T hese flags are the Tampe re d flag (shown in
Figure 2-5 as "S/T "), and the Opene d flag (shown in Figure 2-5 as "O/C").
Note that in the Evaluation Software, flags that are set appear in red, while
unset flags appear in black.
If you have followed this guide step by step up to this point, you should
have both flags off (black). If you cleared the list, click Single
Inte rrogation (the upper one) again to see the flags.

Chapter 2
Quick Start
The O pene d flag is set (on) whenever the Sealing Wire is open, and unset
(off) whenever it is closed. That explains why the O/C flag appears black.
Now, open the Sealing Wire by pulling one of its ends out of the socket.
Click the Single Interrogation button again to see that the O/C flag has
turned red (on).
You may have noticed that also the S/T flag has become red. This indicates
that the DataSeal was Tampered. If you now close the Sealing Wire, this
flag will remain on, even though the O pene d flag will turn off again. Try it
now: close the wire, and click the Single inte rrogation once more. You
should see the O/C flag black again, but the S/T remains red.
No matter how many times you would open and close the wire now, the
Tampe re d flag remains set, to indicate that it was opene d at least once.
You can try it if you want.
You may be wondering by now, whether this tutorial led you to a state
where the DataSeal is irreversibly tampered, meaning that the DataSeal is
no longer usable! Well, you can relax because the Hi-G-T ek DataSeal is a
reusable seal, meaning that you can clear that Tampe re d flag. T he
Tampe re d flag can be cleared only when the Sealing Wire is closed, and it
is done by sending a Se t command to the DataSeal. That’s right, that's the
same command you sent after the Hard Wakeup in the "Preparing the
Seal/T ag" section.
You can send this command from the Ve rify & Se t windows too. After
performing a Single Inte rrogation, click on the line in the list that shows
the Seal ID of the DataSeal you want to Set. Notice that the Seal ID now
appears in the Seal ID box at the top part of the window. You may also
type the Seal ID there manually if you prefer. Make sure that the Sealing
Wire is closed, and then click on the Set button (inside the Addresse d
Ve rify and Se t frame).

Quick Start
After about 5 seconds, you should see a green "Set OK" message in the
Result box (in the upper left side of the window). If you see a "Set Failed"
message instead, it means that the Sealing Wire is not properly closed. If
you see a different message, refer to chapter 0 for troubleshooting.
Perform another Verify interrogation (click the Single Inte rrogation
button). You should see now that both the Tampe re d (S/T ) and O pe ne d
(O/C) flags are clear (black), just as they were in the beginning.

Power Supply Requirements
General
The DataReader supply voltage is chosen according to the model, either
12v, 24v or 48v (see the specifications of the different models in chapter
10.
Power supply wattage: each DataReader consumes maximum 1.7W, so the
power should tolerate the number of DataReaders in the chain multiplied by
each DataReader’s power consumption.
- 56 -
Hi-G-Tek Ltd. Microelectronics & Asset Tracking Technology
Chapter 5
DataReader Installation and Operating Instructions
Example: 10 DataReaders connected in a daisy chain require 10x1.7=17W
of power supply.
Note that if the power supply is installed in a high temperature area (usually
above 40° C), there is a derate in power supply wattage. (Refer to your
power supply manual).
For safety reasons, power supply current should be limited to 3A. Current
limitation should be done internally in the power supply, or externally with
a 3A fuse.
Both in the Outdoor and Indoor systems, the power supply should be
installed indoor.
When power supply cable ends are connected directly to system cable, a
proper isolation should be made. Using heat shrink tube is recommended.
5.5.2
Indoor Installation
When the DataReader is installed indoor, the power supply used should be

DataReader Installation and Operating Instructions
Cable Selection
The cable is used for power supply to DataReaders in a chain and for RS485 serial communication.
For most applications, 3 or 4 pairs of 24AWG shielded cable is adequate.
The serial communication requires shielded twisted pair cable, the power
supply requires low ohmic resistance of the conductors.
Cable connection:
1 pair for RXA and RXB signals.
1 pair for TXA and T XB signals.
SI GNAL GND may be connected to shield or to a pair of wires (shield
connection is recommended, though it depends on the noise level of the
specific environment).
For the power supply: two main issues should be considered: max current
carrying capacity and wire resistance.
Max current capacity: For 24AWG cable, the jacket is heated at 1°C at
0.1A current, max temperature is 80°C. So, this cable can carry a max of
2A at 60°C. ( (80°-60°)*0.1 ).
This calculation should be done for the application specific requirements.
Wire resistance: The voltage drop across the cable may cause insufficient
voltage to the last DataReaders in the chain. Calculation of voltage drop for
the certain setup should be done, in order to avoid this.
In most cases, the solution for such problems can be connecting a pair of
wires for the supply (2 for supply and 2 for return), using thicker cable, or
- 58 -
Hi-G-Tek Ltd. Microelectronics & Asset Tracking Technology
Chapter 5
DataReader Installation and Operating Instructions
using higher temperature rated cable. Environmental considerations: In an
outdoor installation, the cable should withstand all outdoor conditions,
including water proof, temperature, ruggedness etc.
Example:
A setup of 10 DataReaders with 20 meter 24AWG cable between
DataReaders and 24v supply to the first DataReader.
The ohmic resistance between DataReaders is 3.4 Ohms (20 meter of
supply and 20 meters of return). Calculating the voltage drop across the
lines gives 5v only, left to the last DataReader in the chain. T his is below
DataReader specification of DataReader minimum supply voltage. If two
conductors are used for supply and return, the ohmic resistance would be
3.4/2=1.7 ohm. The voltage to the last DataReader in the chain would then
be 17v, well above the minimum voltage required.
If you experience difficulty calculating the voltage drop across the supply
line, contact your distributor for assistance.
5.7
Installation Notes
The DataReader is distributed to a commercial/industrial use only, and
should only be sold to the professional customers.
When installed outdoors, the unit shall be installed in accordance with the
NEC or CEC.
Installation must be performed according to this user manual, and by a
professional personnel only.
It is the responsibility of the installer to ensure that when using the outdoor

System Overview
System Overview
6.1
System description
The Hi-G-T ek system consists of the following components:
1. DataSeal
The DataSeal is a sophisticated device, which includes 2
transmitter/receiver units (one for high frequency/long range and another
one for low frequency/short range communications), real-time clock,
processor, memory and sensing circuitry for sealing verification. T he
Sealing Wire prevents any attempt of opening, bypassing, or tampering
with the DataSeal without alerting the system and recording the event.
Data may also be written into and read from the DataSeal to store and
retrieve general information. The DataSeal can communicate both in low
frequency with short range devices, such as the DataTerminal and
MicroDataReader, and in high frequency for long ranges with the
DataReader, together allowing a broad range of applications.
2. DataTag
The DataTag is a variant of the DataSeal device. Instead of the Sealing
Wire it has a removal sensing mechanism. T his makes it more suitable for
cases where you want to tag goods, but you don't have to seal them. Other
than that, it is identical to the DataSeal device.
3. MagneticDataSeal
The MagneticDataSeal is a variant of the DataSeal device. Instead of the
Sealing Wire it has a Magnet element. This makes it more suitable for cases
- 64 -
Hi-G-Tek Ltd. Microelectronics & Asset Tracking Technology
Chapter 6
System Overview
where you want to sense if the door is open but you can’t seal it. Other than
that, it is identical to the DataSeal device.
4. DataReade r
The DataReader uses in high frequency (long range) RF communication to
communicate with the DataSeals mainly for reading their IDs and their
Statuses. T he DataReader can also be used for reading and writing
information to and from the DataSeal and retrieving logged events from the
DataSeal. Each DataReader can communicate with numerous DataSeals
simultaneously and verify their presence and status. T he DataReaders can
also be chained together to allow a longer and wider range of coverage.
DataReaders must be connected to a controlling computer that control
them.
5. DataTe rminal (previously known as Hand Held T erminal or HHT )
This is a mobile handheld device which includes a keypad, a small LCD
screen, a low frequency receiver/transmitter, and an RS-232 interface.
The main things that you can do with the DataTerminal are: Reading a
DataSeal's ID and Status; Reset the DataSeal for a new use ("Set"
command); reading and writing data to and from the DataSeal – for
example: manifest number, truck number, driver name etc.; reading the
events that were logged in the DataSeal; T ransferring this information to
and from a PC.
6. DataPort (Previously known as Low Frequency T erminal, or LFT)
The DataPort is a simple low frequency modem. It includes a low
frequency transmitter/receiver and an RS-232 interface that connects to a
PC. In other words, it enables a PC to communicate almost directly with a
DataSeal. In general, the DataPort enables the PC to perform the same
Hi-G-Tek Ltd. Microelectronics & Asset Tracking Technology
- 65 -
Chapter 6
System Overview
operations as the DataT erminal, given that an appropriate software exists in
the PC.
7. MicroDataRe ade r
The MicroDataReader is a key ring size mobile device that includes a lo w
frequency transmitter/receiver, 1 or 2 buttons and a LED indicator. Using
the MicroDataReader you can perform the following functions:
1. Verify – The LED will turn green if the DataSeal's Status is OK, or
to red if it's Tampered.
2. Set (Optional) – prepares the DataSeal for a new use. The type of
the Set command (normal, Soft Set or Suspended Set) is model
specific. Hi-G-T ek can provide MicroDataReaders with different
commands if required.
6.2
6.2.1
DataSeal and DataReader Modes of Operation
DataSeal Modes of Operation
Generally speaking, a DataSeal can be used in any of the following ways:
1. O peration Mode (Normal Mode )
This is the normal and most basic mode of operation. In this mode, the
DataSeal is on standby most of the time. Once every predetermined period,
called Tw, the DataSeal samples the HF (high frequency) channel
searching for a transmission from a DataReader. If it detects such
transmission, it listens and answers as needed. The default value of T w is 3
seconds, which is the most appropriate for most applications. In the
Operation Mode, the DataSeal also listens constantly to the low frequency
channel and responds as needed. During the Operation Mode the DataSeal
- 66 -
Hi-G-Tek Ltd. Microelectronics & Asset Tracking Technology
Chapter 6
System Overview
logs events (like opened, closed, tampered, etc.) and stores them internally
in the Events Memory.
2. Dee p Slee p Mode
This mode should be use d when the DataSeal is not in use in order to
conserve energy. DataSeals always leave the factory in this mode. It is
possible to enter a DataSeal to this mode also by using high frequency or
low frequency command. To exit this mode, interrogate the DataSeal using
low frequency (for example, using a DataTerminal), or send a Hard
Wakeup command in high frequency using a DataReader.
Note : While in Deep Sleep mode, no Events are recorded. Events aren't
recorded also after waking up the DataSeal, until a Set command is
performed. In other words, after waking up a DataSeal, you must also
perform a Set command in order for the DataSeal to start record events.
3. Ale rt Burst Mode
This mode is similar to the Operation Mode. In addition, whenever the
DataSeal is opened, it transmits an Alert Burst message in the high
frequency channel. T he DataReader and the application should both be
configured to receive and handle the alert message. A DataSeal can be
configured also to transmit Burst messages on other events.
4. Footprint Eve nts Mode
This mode is a way of using the DataSeal, rather than a configuration of the
DataSeal. When the DataSeal receives a special variant of the Verify
command in low frequency or in high frequency, it records a certain Event
called "Read", that includes the DataReader's ID or the low frequency
device's ID. To use this special command in the DataReader, the
DataReader has to be configured accordingly. This mode is useful to
determine the DataSeal's track if there are several DataReaders, or check

points with DataT erminals along the way. In this scenario, you can know
the DataSeal's track by reading its Events, without having to have these
DataReaders connected to any central system.
6.2.2
DataReader Modes of Operation
There are several aspects that determine the DataReader's mode of
operation. T hese aspects are determined by the Mode parameter, which is a
bit oriented parameter.
5. Carrie r Sense Collision Pre vention
Just like you can't understand what two people are saying when the speak
simultaneously, that way a DataSeal can't understand two DataReaders that
transmit simultaneously. When two (or more) close DataReaders aren't
controlled by the same controlling computer (or by controlling computers
that are synchronized among them), there's a chance that they will try to
transmit simultaneously. In order to prevent that, the DataReaders can be
configured to sense for a carrier (transmission of another DataReader or
DataSeal) before they start transmitting. When a DataReader is configured
for Carrier Sense, each time before it transmits something it listens to the
frequency, and only if it's clear (no one else is transmitting), it start
transmitting its own message.
6. Burst Re ceiving Mode
When DataSeals are operating in Alert Burst mode, the DataReader’s
receiver must be ON at all times in order to receive the Burst messages.
The controlling computer has to query the DataReader periodically to
receive the Burst messages that the DataReader received.

System Overview
Most Comm on Comm ands and Seal Status
6.3.1
Most Comm only Used Comm ands
There are a number of key commands that are used in most applications, as
they enable the basic operation of the system. These commands are:
7. Ve rify
The Ve rify command is use d to detect DataSeals which are located within
the DataReaders Receiving Zone and also verify their state. The DataSeals
which respond may be in one of two states. T he DataSeals may be in either
the normal state, meaning the have not been tampered with, or in the
tampered state, meaning they have been tampered with. Additional
information can also be queried from the DataSeal. T his is the most useful
and commonly used command in the system.
8. Tampe re d
The Tampe re d command is used to communicate with tampered
DataSeals. The command operates the same as the Ve rify command only
DataSeals which are in the T ampered state respond. T he aim of the
command is to provide high priority to tampered DataSeals in a crowded
DataSeals environment.
9. Se t
The Set command is use d to set a DataSeal for a new use. T he Sealing
Wire must be connected and closed in order for a DataSeal to be set. T he
Se t command deletes all Events stored in the Events Memory and is the
first new Event recorded in the DataSeal. T he DataReader can send the Se t
command to up to 8 DataSeals simultaneously.
10. Suspende d Set
Hi-G-Tek Ltd. Microelectronics & Asset Tracking Technology
- 69 -
Chapter 6
System Overview
Similar to the Set command, Suspende d Se t is used to set a DataSeal for
new use. Unlike the Set command, when performing a Suspende d Se t
command, the Sealing Wire Must be opened (or completely disconnected
from the DataSeal). T he DataSeal will become armed (Set) once the
Sealing Wire has been connected to the DataSeal and closed.
11. Approve Open
The Approve Open command allows a Sealing Wire to be opened after the
DataSeal has been set in a way that the application can determine that the
DataSeal was opened with an approval. When the Sealing Wire will be
opened after receiving this command, the application will be a ble to
determine that the opening is approved by examining the Approved Open
flag in the DataSeal's Status.
6.3.2
DataSeal's Status
The DataSeal's Status consists of 4 bytes. A DataReader may be used to
request the DataSeal's Status. The DataSeal's Status is use d to indicate the
DataSeal's current state and is a bitwise value. Each bit in the Status
represents a specific status flag. The DataSeal's Status is divide d into the
Short Status and Long Status parameters as explained below:
The DataSeal's Short Status parameter consists of 1 byte (8 bits) which is
a subset of the Long Status parameter. The Short Status contains the most
important flags. T hese flags are:
1. Tampe re d – The Tampe re d flag gets set if the Sealing Wire was
opened or tampered with. It remains set even if the Sealing Wire is
closed again. It can only be unset by performing on of the Se t
commands.
2. Low Battery Warning – Battery is low, replace the DataSeal.
3. O pene d – Indicates that the Sealing Wire is open.
- 70 -
Hi-G-Tek Ltd. Microelectronics & Asset Tracking Technology

4. Suspende d Se t – A Suspende d Set command was performed, and the
Sealing Wire wasn't closed yet.
5. Se aling Wire Change d – Indicates that the Sealing Wire's electronic
characteristics have changed since the DataSeal was Set.
6. Dee p Slee p – Indicates that the DataSeal is in Deep Sleep mode.
7. Ge neral Error – Indicates an error with the DataSeal that is not
represented in the DataSeal's Short Status.
8. Approve d O pen – If the DataSeal O pe ne d flag is on, the Approve d
O pen flag means that the opening is approved. If the DataSeal's
O pene d flag is off, it means that the next open will be approved, if
performed during a certain period.
The DataSeal's Long Status contains the Short Status flags as well as 3
additional bytes that together represents the complete DataSeal's status. For
a detailed description of the Long Status, see chapter 8.
6.4
System Planning
When planning an application, attention should be paid to both system
operation and topology. Application requirements and electromagnetic
environment characteristics should also be taken into account.
2 basic types of applications are possible: Fixed DataReader applications
and Mobile DataReader applications. A complex application that combines
DataReaders in both configurations is also possible.
The Fixed DataReader applications are applications where the DataReaders
are mounted at a fixed site. The Mobile applications are situations where
the DataReaders are mounted on vehicles for monitoring DataSeals in
transit. Mobile applications are normally implemented using the
TrackingDataReader, but may also be implemented using a DataReader

System Overview
connected to any mobile controller (E.g. laptop, palmtop, etc), that has a
serial communications port.
6.4.1
Electrom agnetic Environment
Radio Frequency Communication is the basic technology used by the
system. While this is a very robust method for communicating with remote
devices, several issues should be considered when planning a site.
Metal walls should not be used to shield the remote devices.
Communication distance between remote devices may vary due to
atmospheric conditions and other electromagnetic interferences.
Communication distance may also vary according to one or more of the
following:
•
Line of sight between devices – existence and clearance.
•
Proximity to metal objects.
•
Indoor or Outdoor environment.
•
Antenna orientation between the devices.
It is recommended to map the site with actual devices for proper coverage.
When planning the site layout, safe margins should be taken into account to
ensure proper operation at all times. Possible environmental changes
should also be considered.
6.4.2
System Layout
T wo aspects should be considered when dealing with system layout:
1. Radio Frequency Communication Layout.
2. Line Communication RS-485 or RS-232 Layout.
- 72 -
Hi-G-Tek Ltd. Microelectronics & Asset Tracking Technology
Chapter 6
System Overview
6.4.2.1 Radio Frequency Communication Layout.
When only one DataReader is in use, the previously mentioned
environmental considerations are all that need be taken into account.
When more than one DataReader is in use, it should be understood that in
the same area only one DataReader can communicate with the DataSeals at
the same time. Interference will be cause d by more than one DataReader
Trying to communicate with the DataSeals in the same period of time. The
DataReade rs should be synchronize d using the application software or
using the Carrie r Sense mode . Several DataReaders may operate
simultaneously provided that it has previously been confirmed that they
will not interfere with each other.
6.4.2.1.1 Cellular Layout
Cellular topology should be used to ensure efficient coverage of a large
area. The following diagram illustrates the concept:
Hi-G-Tek Ltd. Microelectronics & Asset Tracking Technology
- 73 -
Chapter 6
System Overview
Re ade r Zo ne
DataReaders must be properly placed to ensure there are no dead zones
within the defined area. Overlaps should be as shown in the above drawing.
DataReader's Receiving Zone is the term used to describe the area of
reliable communication covered by a DataReader. T he DataReader's
Receiving Zone is also called a Cell. As the drawing illustrates, it is
extremely important that the application software controls and synchronizes
the DataReader’s operation in order to avoid RF collisions. In other words,
the application software has to make sure that no two DataReaders with
overlapping Receiving Zones transmit at the same time.
6.4.2.2 Line Comm unication RS-485 Layout
The connection of many DataReaders to a controlling computer is done via
the RS-485 protocol. Up to 32 DataReaders may be connected to one serial

System Overview
communications port, depending on the type of RS-485 to RS-232
converter used.
T wo topologies can be used:
A long daisy chain connection, where all the DataReaders are
connected in one long line.
A star-type connection, where the DataReaders are split into groups
and each group is connected directly to the converter.
It is recommended that the second alternative be used wherever possible. A
star-type connection provides better tolerance to connection failures. This
alternative is also preferable from the power supply point of view, as only
one power supply for the DataReaders is necessary. The power supply
should be located near the converter. When the line is divided into
segments, the voltage drop along the segments is smaller.
6.5
Systems Segregation
When Hi-G-T ek has designed the system, several security and operational
considerations have been taken into account:
Similar equipment belonging to one company should not be able to
mess with another company's system either intentionally or
unintentionally.
Limit unauthorized access between different departments of the same
company. Equipment belonging to one department of a company
should not be able to interfere with equipment of another department,
either intentionally or unintentionally.
Service Providers should be able to communicate with their customer's
equipment in order to supply common services to several companies.
This should be done in an authorized an limited manner.
Hi-G-Tek Ltd. Microelectronics & Asset Tracking Technology
- 75 -
Chapter 6
System Overview
DataSeals may have to be divided into groups that are not related to
companies or departments.
6.5.1
Com panies Segregation by OrgID
OrgID is a unique value assigned to each company by Hi-G-T ek or by one
of its authorized dealers. Every device supplied to that company is preprogrammed with the same OrgID at production, and the customer can't
change it ever again. In every communication between two devices, the
caller (e.g. DataReader) sends its own OrgID value. When the consignee
(e.g. DataSeal) receives the message, it first compares the OrgID it received
with its own OrgID, and only if they match the consignee performs the
command and sends its response. If a DataSeal receives a message a
different OrgID than its own, it turns on the Ille gal O rgID flag in the Long
Status, and ignores the message.
There's one exception in which a DataSeal can respond to a message with a
different OrgID in order to allow collaboration with service providers. This
is described in more details in section 6.5.3.
6.5.2
Department Isolation
Department is a unique value assigned by a company to a group of devices
belonging to the same department. It is possible to isolate equipment
between departments by using the Department parameter in the various
devices.
The default value of Department is zero in all devices. When set to that
default setting, all the devices can communicate with one another without
any limitations.
If a DataReader's Department value is not zero, it can communicate only
with DataSeals that has the same Department value.
- 76 -
Hi-G-Tek Ltd. Microelectronics & Asset Tracking Technology
Chapter 6
System Overview
If a DataReader's Department value is not zero, it can communicate with all
of the DataSeals in the same organization, even if their Department value is
non-zero. Such a DataReader is considered "Supervisor". T he De partment
parameter both in DataReaders and in DataSeals can be changed by the
user at any time.
6.5.3
Services to Several Companies by a Service Provider
The DataSeal has a boolean parameter named Global, which is designed to
allow a Service Provider to service several customers. If a DataSeal’s
Global parameter is on, then that DataSeal will respond to any Ve rify
command from any DataReader, regardless of OrgID. T he Ve rify response
will be a limited one, containing only a certain few of the DataSeal
parameters. See the description of the Global parameter in chapter 8 for a
list of the parameters that can be included in the Ve rify response in this
case.
Note : T he Global parameter is programmed during production, and it
must be define d and re queste d in advance .
6.5.4
Subgroups of DataSeals
When a DataReader sends a Ve rify command In order to detect the
DataSeals in its area, it can receive only a limited number of responses at a
time. If there are many DataSeals in the DataReader's Receiving Zone there
could be too many DataSeals trying to respond at the same time, and that
would cause that none of them will be properly received by the
DataReaders. In order to avoid that, the DataSeals can be divided into small
groups and each group be assigned a unique value called ADI. When the
DataReader will execute a Ve rify command, it would be able to specify a
specific group, and only DataSeals that belong to that group will respond. If
the DataReader would iterate through the groups, it can receive all the
DataSeal in a relatively short time.
Hi-G-Tek Ltd. Microelectronics & Asset Tracking Technology
- 77 -
Chapter 6
System Overview
For that purpose, the DataSeal and DataReader devices have an ADI
parameter. T he ADI parameter works very similar to the De partment
parameter, with 2 differences: ADI is 4 bytes while De partment is 1 only
byte, and the controlling computer can explicitly specify a different ADI
for each RF command it requests the DataReader to transmit.
The ADI parameter can be used also to create groups by usa ge in other
scenarios.
6.5.5
OrgID, Department, Global and ADI Impact on DataSeal’s
Response
The following statements summarizes when and what a DataSeal responds:
1. If the DataReader's De partment parameter is zero, the De partment is
always considered to match.
2. If the DataReader sends a zero ADI, the ADI is always considered to
match.
3. OrgID doesn't match and Global is on: DataSeal will respond with
limited Ve rify command only.
4. OrgID doesn't match and Global is off: DataSeal will not respond.

DataSeal's Memory
The DataSeal's Memory is divided into 2 sections: Events Memory and
User Data.
6.6.1
Events Mem ory
This memory stores the Events detected by the DataSeal during normal
operation. This memory can contain up to 55 Event records.
The memory has a FIFO type structure with 2 segments: T he first segment
can store 45 Events and is a simple FIFO buffer. The second segment can
store 10 Events and is a cyclic buffer with the last Events detected.
Hi-G-Tek Ltd. Microelectronics & Asset Tracking Technology

segment: 10
Events
Some Events are caused by an external intervention (like Opened and
Closed), while others are caused by internal procedures.
The most common Events are the Se t, Tampe re d, Opene d and Close d
Events. See chapter 8 for a complete list and descriptions of each Event
type.
6.6.2
User Data
User Data is the memory segment where free data can be written and read.
For example, the electronic manifest can be stored in this memory.
The User Data can be read and written using the Read Data and Write
Data RF commands accordingly. T he User Data can also be read by the
Ve rify and the Read Multi Access Data RF commands. The size of the
User Data memory segment is 2KB.
- 80 -
Hi-G-Tek Ltd. Microelectronics & Asset Tracking Technology
Chapter 6
System Overview
Even though all the User Data is simply a flat memory segment, the lowest
53 bytes are of special meaning for the DataTerminal. If you're using or
considering to use a DataT erminal in your system someday in the future,
you should use these 53 bytes in a way that is compatible with the
DataTerminal. The DataT erminal uses the first 53 bytes as follows:
6.6.2.1 The User Data portion used by the DataTerm inal
The DataT erminal is capable of viewing and editing 48 bytes (addressed 5
– 52) of the User Data as a structure of ASCII fields. T his structure has to
be defined first by the user, using a special PC software provided with the
DataTerminal, and then uploaded to the DataT erminal. The structure
definition includes the labels and sizes of the fields and is assigned an
identifier (called UDT ), and a version number. When the user writes User
Data using the DataT erminal, the DataT erminal always stores this identifier
and version number in address 0, and the date and time when the data was
written, in addresses 1-4.

System Overview
3. Se t – Uses to prepare DataSeals for a new use. Sealing Wire must be
attached and closed prior to the Set command. This command can be
sent up to 8 DataSeals simultaneously.
4. Suspende d Set – Similar to the Se t command except that the Sealing
Wire must be open prior to performing the command and the DataSeal
gets set once the Sealing Wire is closed. T his command can be sent to
up to 8 DataSeals simultaneously.
5. Soft Se t – Similar to the Se t command, the Soft Set command is use d
to prepare DataSeals for a new use. Unlike the Se t command, the Soft
Se t command does not delete the previously recorded Events in the
Events Memory. This command can be sent to up to 8 DataSeals
simultaneously.
6. Dee p Slee p – Puts the DataSeal into Deep Sleep mode. T his command
can be sent to up to 8 DataSeals simultaneously.
7. Hard Wakeup – Brings DataSeals which are in Deep Sleep mode back
to normal operating mode. This command can be sent to up to 8
DataSeals simultaneously.
8. Start Ale rt Burst Mode – Puts DataSeals into Alert Burst mode. This
command can be sent to up to 8 DataSeals simultaneously, or to all the
receiving DataSeals.
9. Stop Ale rt Burst Mode – Brings DataSeals which are in Alert Burst
mode back to normal operating mode. This command can be sent to up
to 8 DataSeals simultaneously, or to all the receiving DataSeals.
10. Acknowle dge Alert Burst – Acknowledges the reception of Alert
Burst messages from DataSeals. T he Acknowle dge Ale rt Burst
command tells the DataSeal that its message has been received. After
receiving an Acknowle dge Ale rt Burst command, the DataSeal stops
transmitting its Burst message until a new T ampered event is detected.
This command can be sent to up to 8 DataSeals simultaneously.
11. Read Data – Retrieves data from a DataSeals’ User Data area.
Hi-G-Tek Ltd. Microelectronics & Asset Tracking Technology
- 83 -
Chapter 6
System Overview
12. Write Data – Writes data into a DataSeal's User Data area.
13. Rese t Data – Erases all the data in a DataSeals’ User Data area.
14. Se t/Reset Status – Sets or resets specific flags of the DataSeal’s Long
Status.
15. Write Parame ters – Writes new values to one or more DataSeal
parameters.
16. Read Paramete rs – Reads the values of one or more DataSeal
parameters.
17. Addresse d Ve rify – The Addresse d Ve rify command is the same as
the Verify command except that it is applicable to only one DataSeal.
This command is most commonly used to verify that a specific
DataSeal is located within a DataReader’s Receiving Zone.
18. Multi Addresse d Ve rify – T he Multi Addresse d Ve rify command is
the same as the Addresse d Ve rify command, but is applicable to up to
7 DataSeals simultaneously.
19. Read Eve nts – Reads part of or all Events stored in the DataSeal’s
Events Memory.
20. Approve Open – Permits to open a DataSeal after it has been Se t. If
opened, both the DataSeal's Approve d O pen and the Tampe re d flags
will be set. This command is intended for recognizing permitted
DataSeal openings.
21. Start Force d Burst – Forces the DataSeal to send a special Burst
message called Force d Burst. It is most useful when this command is
executed in Low Frequency, and by that causing the DataSeal to send
information to the DataReader. When used in high frequency, it may be
executed in one DataReader, while a different DataReader (in another
place for example), should receive the Force d Burst message.
22. Te mporarily Disable HF – Disables the HF channel in a DataSeal for
a specified period. This is useful to conserve battery when the area may

7.4.1
Executing Broadcast Verify Command
The Broadcast Ve rify command (sometimes referred to simply as Ve rify)
is a command that collects information from all the DataSeals that receive
the command (given that their OrgID, Department and ADI match). This
command is the most powerful command, and has many parameters that
enable to fine tune its behavior. A complete description of all the
parameters is given in chapter 8. Normally, the default values of the
parameters are adequate, but you may change them to best suit your needs.
If you want to execute the Broadcast Ve rify command only once, click on
the Single Inte rrogation button (shown in Figure 7-0). You can also
execute the Broadcast Ve rify command continuously (or cyclically) by
- 94 -

clicking the Cyclical Interrogation
button. You can control some
aspects of the cyclical interrogation
from the cyclical interrogations
control frame (item #8 in Figure
7-0) as described in section 7.4.4.
The results (responses) of the
Broadcast Ve rify command are
displayed in the Broadcast Verify
responses list (item #7 in Figure
Figure 7-0

appended to this list. To clear the list click on the Rese t button on the lower
right side of the window.
Each response in the Broadcast Verify responses list contains the following
information:
Seal ID
Events: The number of Event records that exist in the DataSeal.
Seal Short Status: This column is divided into 7 sub columns, each
represents a single flag in the DataSeal's Short Status. If the flag is set
(on), the flag appears red, and if unset (off) the flag appears black. T he
flags are:
•
S/T – Set/T ampered: if on, indicates that the DataSeal wa s
tampered.
•
LBW – Low Battery Warning.
•
O/C – Open/Close: if on, indicates that the Sealing Wire is open.
•
SS – Suspended Set: if on, indicates that the DataSeal is in
Suspended Set state.

can be determined by other flags in the DataSeal's Long Status,
that are not included in the Short Status.
•
Session: T his column displays the sequential number of the session
(interrogation). This number is increased with each new Ve rify
command. This parameter is added by the Evaluation Software, and
is not part of the DataSeal's response.
•
Rdr (Reader): The Reader Address of the DataReader that executed
the command. T his parameter is added by the Evaluation Software,
and is not part of the DataSeal's response.
You can sort the list using any of the following columns by clicking on the
title of that column: Seal ID, Events, Session and Reader.
The content of the Broadcast Verify responses list can be saved to a tabbeddelimited text file (Seals.txt), by choosing Save to Seals.txt from the File

Executing Addressed Verify Comm and
The Addre sse d Ve rify command is similar to the Broadcast Ve rify
command except that it addresses only one specified DataSeal, instead of
all the DataSeals that receive the command.
In order to execute an Addresse d Ve rify command, you must first specify
the Seal ID of the DataSeal you want to interrogate. You do it by typing the

is to select the Seal ID from the
Broadcast Verify responses list
(Item #7 in Figure 7-0), if it
previously responses to Broadcast
Ve rify.
Figure 7-0
As in the Broadcast Ve rify frame,
here you also have the Single
Inte rrogation and the Cyclical Inte rrogation options: clicking the Single
Inte rrogation button will execute the Addre sse d Ve rify command only
once, while clicking the Cyclical Inte rrogation button will execute the
Addresse d Ve rify command cyclically according to the options that are
selected in the Cyclical Interrogations control frame (Item #8 in Figure 7-0)
as described in section 7.4.4.
The result (response) of the Addresse d Ve rify is displayed in the
Addresse d Verify response indicators (Item #5 in Figure 7-0) and in the
Seal Status indicators (Item #6 in Figure 7-0).
Figure 7-0
The Addresse d Ve rify response indicators contains the following fields:

Rdr Addr (Reader Address) – T he Reader Address of the DataReader
that executed the command. This field is added by the Evaluation
Software and is not part of the DataSeal's response.
Status – OK or T ampered.
In addition to these indicators, the Seal Status indicators also indicates the
DataSeal's Long Status. Flags that are set appear in red, while unset flags
appear black. For a complete list of the flags in the DataSeal's Long Status,
and their meanings see chapter 0 8.
If the DataSeal didn't respond to the Addre sse d Ve rify command, the
Result indication box (Item #4 in Figure 7-0) displays a red message "Seal

7.4.3
Executing Set Comm and
The Set command is used to prepare a DataSeal for a new use. T he Se t
command is addressed to a specific DataSeal (in fact, it can be addressed to
up to 8 DataSeals simultaneously, but the Evaluation Software does not
support it through this window). In order to execute a Set command you
must first specify the DataSeal you want to send the command to in the
Seal ID box (Item #3b in Figure 7-0). You can do it also by selecting it
from the Broadcast Verify responses list (Item #8 in Figure 7-0) if it
appears there.
The Sealing Wire must be close in order for the Set command to succeed.

7.4.4
Cyclical Interrogations Options
The Cyclical Interrogations control frame (Figure 7 0- ) contains some
options that allow you a variety of ways to execute cyclical interrogations.
In the No. of cycles box you can
enter the number of cycles that will
be executed. If you enter "-1", the
Evaluation Software will execute
interrogations until you click on the
Stop Cycle button. Even if No. of
cycles is not "-1", you can click on
the Stop Cycle button to stop the
interrogations.
Figure 7-0
In the System Pause field you can specify the pause between one
interrogation to the next in seconds.
The Loop through all Reade rs check box is available if more than 1
DataReader is defined. If this check box is checked, the Evaluation
Software will execute the first interrogation using the first DataReader in
the list, the second interrogation using the second DataReader and so on.
After the last DataReader was used, the first one is used again, and so on.
For example, it there are 3 DataReaders, and No. of cycles is 8, the order
that the DataReaders will interrogate will be: 1,2,3,1,2,3,1,2.
The Session # box indicates the sequential number of the interrogation. T he
Evaluation Software increases this value with each new interrogation. T o
reset this number, and to clear the Broadcast Verify responses list, click the

Executing Any Command using the All Comm ands
Window
The All Commands window lets you execute any RF command and play
with the "bits and bytes" of the RF protocol. Normally, when a software
programmer writes an application, he doesn't have to play with the bits and
bytes, because the DataSealLib software library (COM DLL) provides
higher level interfaces, but acquaintance with the bits and bytes can be very
helpful sometimes. Also, this is the only place in the Evaluation Software
that you can execute all the RF commands.
To access the All Commands

cyclical execution click the Stop button. Using the System Pause field you
can specify the pause in seconds between two interrogations in a cycle.
The Re ade r Session field displays the duration in milliseconds of one
interrogation of the selected command. For some commands you can also
change this value. However, note that specifying lower value than the
default will usually cause an error.
When the command completes, the Result box indicates whether the
command succeeded or failed.

Addressed Verify
The Addresse d Ve rify command is identical to the Verify command,
except that it is addressed to a specific DataSeal.
This command is an Addressed command, and therefore the Seal ID of the

executing the command.
The arguments of the command are identical to the arguments of the Verify
command. Note however that there is no use in specifying Rr that is
different than Nr in Addresse d Verify, because there are no collisions. Nr
and Rr can be greater than 1 in order to increase the probability of

Set
Figure 7-0
The Se t command is used to prepare a DataSeal for a new use. If the
Sealing Wire is open while the DataSeal receives the command, the
command is not executed. If the Sealing Wire is closed, then all the Event
records are deleted, the Tampe re d flag is cleared, and a new (first) Event
record is written to indicate the Se t operation.
This command is multi-addressed, and can be sent to up to 8 DataSeals in a
single command. You must enter between 1 and 8 Seal IDs in the
Se als/Tags ID box, one in each line, before executing the command.
The Seal Status in the response indicates whether the command succeede d
or failed: If the Status is OK (closed, not tampered) the command
succeeded, and if it is tampered the command failed. An example of this
can be seen in the Re sponse box in Figure 7 0- : the first row indicates an
open Sealing Wire and T ampered state, (the Se t operation failed), while the
second row indicates a closed Sealing Wire and OK state (the Set operation
succeeded).

in the Short Status is set. Only when the Sealing Wire is closed, the Event
records are deleted, the Tampe re d flag is cleared and a new Suspende d
Se t Event record is written.
If the Sealing Wire was open at the time of the command execution, the
DataSeal's will indicate the following flags in the Status: Tampe re d,

System Parameters and Comm ands
System Parameters and Commands
This chapter describes the details of the communications with the DataSeal
and the DataReader. Even though Hi-G-T ek publishes the RS-232/485
protocol of the DataReader, and part of the RF protocol, this manual does
not cover these details. Instead, it describes the commands and the
parameters in a more conceptual way, with syntax and examples in Visual
Basic as they can be used through the DataSealLib COM library. Note
there's also an online help that is supplied with the library. T his online help
is more technical than the explanations in this chapter: while this chapter
explains the concepts, the online help describes the COM interface in more
details.
8.1
The High Frequency RF Protocol
8.1.1
The Basics
In order to conserve power, the DataSeal is "asleep" most of the time. It
only opens its High-Frequency receiver for a short time every
predetermined period – usually 3 seconds. T his fact has some implications
on the RF protocol as explained below.
The interval in which the DataSeal opens its receiver is determined by a
configurable parameter called Tw ( which its default value corresponds to
about 3 seconds). Because the DataSeal listens to the RF only in this
intervals, if a DataReader wants to communicate with that DataSeal, it must
transmit a special signal called Reader Interrogation Header, that is at least
in the duration of Tw, in order for the DataSeal to receive it. When the
DataSeal receives this signal (in the short period that its receiver is open), it
knows that a command should follow, and it waits for that command. After
- 132 -
Hi-G-Tek Ltd. Microelectronics & Asset Tracking Technology
Chapter 8
System Parameters and Comm ands
receiving and performing the command and responding if necessary, it
returns to the state of sleeping and opening the receiver every Tw.
The duration of the Reader Interrogation Header should be 135msec
more than Tw. T he DataReader has a configurable parameter called
Thw that determines this period. Note that the DataSeal's Tw
parameter should be configured with the same value for all the
DataSeals, and the corresponding Thw parameter value should be
configured appropriately in all the DataReaders in a given system.

Figure 8-0 demonstrates the concept of the wakeup period and the Reader
Interrogation Header. T he upper line represents the time line of the
DataSeal, and the bottom line represents the time line of the DataReader. It
is clear to see from that figure why Thw (the length of the Reader
Interrogation Header) should be just a bit more than the Wakeup Period
(Tw).
Hi-G-Tek Ltd. Microelectronics & Asset Tracking Technology
- 133 -
Chapter 8
System Parameters and Comm ands
The Reader Interrogation Header is composed of many short segments that
contain indications of when the command starts. This way, when a
DataSeal receives the Reader Interrogation Header, it doesn't have to keep
its receiver open until the command, rather, it goes to sleep exactly until the
command.
Choosing the best Tw and Thw should take in account the following facts:
Small Tw and Thw will improve response times for RF command. Big
Tw and Thw will cause lengthily interrogations.
Small Tw and Thw will shorten the battery lifetime of the DataSeals.
Big Tw and Thw will lengthen it.
8.1.2
Addressing Types
In general, there are 3 types of commands that are distinguished by the way
they indicate which DataSeal or DataSeals will respond:
1. Addresse d (AMM): These commands specify exactly one Seal ID.
Only the DataSeal with that Seal ID responds.
2. Multi Addresse d (BMM List): These commands specify a list of Seal
IDs. The DataSeals in the list respond in the same order as they appear
in the list. This way there are no RF collisions between the responses of
the different DataSeals. Multi Addressed commands without arguments
can contain up to 8 Seal IDs in the list. Currently, the only Multi
Addressed command with arguments is the Multi Addre sse d Ve rify,
which can contain up to 7 Seal IDs.
3. Broadcast (BMM): These commands are aimed for all the DataSeals
that receive the DataReader's transmission. There are actually 2 types
of broadcast commands: commands without response and commands
with response. T he commands that do not wait for a response from the
DataSeals are the simplest, in the way that after the DataReader has
- 134 -
Hi-G-Tek Ltd. Microelectronics & Asset Tracking Technology
Chapter 8
System Parameters and Comm ands
transmitted the command, the commands is completed, and whatever
DataSeals that received the command, performed it. T he second type –
commands with response – use the Slotted Aloha concept in order to
overcome potential RF collisions between the responding DataSeals.
The only commands of this type are the (broadcast) Verify and the
Tampe re d commands. T he Slotted Aloha concept is described in the
following paragraph.
8.1.3
The Slotted Aloha Concept
Because the set of the receiving DataSeals is not known in advance, there's
no deterministic way to synchronize their responses. In other words, RF
collisions are unavoidable. However, by using retransmits, the probability
of receiving all the responses can be very high. Here's the way it works:
The command includes 2 arguments that are relevant to this matter: Nr and
Rr. Nr determines the total number of windows (time slots) in which the
DataSeal can respond, and Rr determines how many times the DataSeal
will transmit its response (or: how many time slots the DataSeal will
actually use to send its response). It is clear that Nr should be much greater
than Rr in order to allow many DataSeals to be received. Each DataSeal
randomly chooses Rr time slots in which it will respond. The following
table demonstrates the situation when Nr (number of windows) is 23, Rr
(number of retransmits) is 4, and there are 3 DataSeals in the DataReader's
Receiving Zone:

2 x
Chapter 8
System Parameters and Comm ands
In this table, each row represents one DataSeal, and each column represents
a windo w. An 'X' in a cell represents that the DataSeal sent its response in
the specified window. Note that there are exactly 4 'X's in each row,
corresponding to Rr. You can see that even though there were some
collisions (in windows 4 and 16), all the 3 DataSeals have at least 1
transmission that does not collide with any other transmission.
In order to achieve high probability to receive all the DataSeals, an
estimation of the maximal number of DataSeals that would respond should
be taken in account before selecting the appropriate values for Nr and Rr.
Fortunately, DataSealLib provides a function that calculates the appropriate
values for Nr and Rr according to the maximal number of expected
DataSeals. T his function is the RFParamete rs.De faultsFor method.
In fact, the newer DataSeals (versions 3.0 and above), use an improvement
of the Slotted Aloha concept: Whenever the DataReader receives a specific
DataSeal it sends an acknowledge to that DataSeal, causing it to stop
retransmitting its response. This lowers the probability for further collisions
and can shorten the total time of the interrogation by using lower Nr value,
or allow more DataSeals to be received in the same time. T he
RFParame te rs.DefaultsFor method takes this improvement into account
too.
8.2
DataSeal Parameters
The DataSeal can be configured very flexibly to fit almost any application
requirements. For that purpose it has a set of predefined Parameters that can
be read and/or written. The DataSeal also has some Parameters that are
read-only, either because they are configured in the factory (like the Seal
ID), or because they are status Parameters.
All the Parameters can be read using the Read Parame te rs RF command,
and all the Parameters that are not read only can be written to the DataSeal
using the Write Parame ters RF command. Some Parameters can also be
- 136 -

read using the Verify and Tampe re d commands (including Addressed and
Multi Addresse d Ve rify).
In DataSealLib, all the DataSeal Parameters has corresponding properties
of the Se al object. See the online help for information about how to use
these properties. T here's also an enumeration that contains constants for the
parameter codes (HGTSealParame terCode Enum). This enumeration is
used
by
the
Seal.ReadParame ter,
Seal.ReadParame ters,
Se al.Write Paramete r and Se al.Write Paramete rs methods. Another
enumeration contains the flags of the Verify Mask that allows to read
parameters using the Verify and Tampe re d commands. This is the
HGTVe rifyMaskEnum enumeration, and it is used by the Reade r.Ve rify,

General Structure of an Event Record
There are 2 main types of Event records: Short Event Record and Long
Event Record. In DataSealLib, both types are represented by the SealEve nt
class, but the Short Event Record does not use all the members. T he
following SealEve nt class members are used both in Short Events and in
Long Event records:
Numbe r – The sequential number of the Event record.
Code – The code (type) of the Event record. T he
HGTEve ntCode Enum enumeration contains the constants for these
codes.
Date Time – T he date & time (in UT C) when the event occurred.
Se alStamp – T he value of the Se al Stamp parameter when the event
occurred.
CRC – The Cyclic Redundancy Check code that ensures the validity of
the first part of the record.
The following SealEve nt class members are used only in the Long Event
records:
Code Ex – T he code of the extension of the Event record. This is
always the same as Code + 80h.
Reade r ID – T he ID of the device that caused the Event (for example,
in a Set operation). Note that this is not necessarily an ID of a
DataReader – it could also be the ID of a DataT erminal, DataPort or
any other kind of device that could cause the Event.
Note : If DataSealLib recognizes the Reader ID as a DataReader that it
knows it returns the Reade r object instead of the Reader ID itself.
Se alStamp2 – 2 Additional bytes that contain data specific to the type
of Event. Most Event types does not use this field at all.

High-Frequency RF Comm ands Summ ary
There are 3 groups of HF RF commands: Addressed, M ulti Addresse d
(with or without arguments) and Broadcast (see section 8.1.2 - Addressing
Types for descriptions about these 3 groups). DataSealLib exposes each RF
command as a method of a class: Addressed commands are provided as
methods of the Seal class; Multi Addressed commands are provided as
methods of the Se als class, and Broadcast commands are provided as
methods of the Reade r class.
- 186 -
Hi-G-Tek Ltd. Microelectronics & Asset Tracking Technology
Chapter 8
System Parameters and Comm ands
All of the methods in DataSealLib that execute RF commands take the
following 2 optional arguments (usually these are the last arguments):
RFCommandO bject – This argument is used for controlling specific
issues regarding the way that DataSealLib returns the results of the RF
command. When the command completes, its Result property contains
the results. For further information about this argument and the
RFCommandO bject class see the online documentation.
ADI – This is the ADI (group ID) that will be sent with the command.
See chapter 6 for further information about ADI.
The following sections contain a summary of the (HF) RF commands and
their arguments. The RFCommandO bje ct and ADI arguments are omitted
from each command, because they are common to all and described above.
Arguments that are relevant only to DataSealLib and does not affect the RF
communications, are omitted too. See the online documentation for help
about these arguments. Note that there are default values to almost all
arguments of all the commands. See the online documentation for further
information about these default values.

8.5
Burst Messages
Burst messages are messages that a DataSeal transmits to the listening
DataReaders. Unlike the RF commands, the Burst messages are sent from
the DataSeal not as a response to a command, but asynchronous to the
DataReader's transmissions, as a result of some kind of event.
Be aware that Burst messages may interfere with normal RF commands
transmissions because they are not synchronized with them. Proper system
design should be made in order to prevent or overcome these cases.
There are 4 events that can cause Burst messages: Sealing Wire is opened,
Sealing Wire is closed, T he DataSeal is being put in Deep Sleep (either
through HF or LF), and an event that is initiated by a special RF command
- 210 -
Hi-G-Tek Ltd. Microelectronics & Asset Tracking Technology
Chapter 8
System Parameters and Comm ands
called Start Force d Burst (either LF or HF). Further details about each
type of Burst message are given below.
Burst messages should be enabled in the DataSeal, by sending the Start
Ale rt Burst Mode or Start Ale rt Burst Mode for All Seals command. In
addition, in order for a DataReader to receive Burst message, a special flag
called Allow Burst in the DataReader has to be on. When a DataReader
receives a Burst message, if it's Allow Burst flag (Reade r.AllowBurst
property) is on and it is not currently executing another RF command, it
stores the message inside its memory. The application software should
check for Burst messages periodically in order to receive them, using the
Reade r.GetBurstMessages method. In addition, Close Burst messages
have to be enabled in the DataSeal by setting the Close Burst Mode flag in
the DataSeal's Long Status.
Burst messages can be sent more than once (for each causing event) in
order to maximize the probability that a DataReader will receive the
message. T he exact number of retries is determined by the Maximal Ale rt
and Close Burst Re tries and Maximal Dee p Slee p Burst Retrie s
DataSeal parameters, and the intervals between them is determined by the
Ale rt and Close Burst Pe riod and the Dee p Slee p Burst Pe riod. For
Force d Burst messages the number of retries an the interval is determined
by the command arguments.
When a DataReader receives a Burst message, it can send an acknowledge
back to the DataSeal, so the DataSeal can stop sending more retries of the
same message. This helps to reduce the DataSeal's battery usage and make
the RF environment less "noisy". T here are 2 options to acknowledge Burst
messages: automatic and manual.
The automatic acknowledge is sent by the receiving DataReader
immediately when it receives the message. In order to use the automatic
acknowledge,
the
Automatic
Acknowle dge
Burst
flag
(Re ade r.AutoAckBurst property) in the DataReader should be on and also
Hi-G-Tek Ltd. Microelectronics & Asset Tracking Technology
- 211 -
Chapter 8
System Parameters and Comm ands
nd
the 2 bit in the DataSeal's Flags parameter should be on. If the Automatic
Acknowle dge Random Delay flag (Reade r.AckBurstRandomDelay
property) in the DataReader is on too, the DataReader will randomly
choose 1 of 4 windows in which it will send its acknowledge.
The advantages of the automatic Burst acknowledge are:
The acknowledge is very short (about 50ms).
The application doesn't have to take care of it.
The disadvantages of the automatic Burst acknowledge are:
The acknowledge does not ensure that the application received the
message.
If the Automatic Acknowle dge Random Delay flag is off, if more
than one DataReader receives the message, and both will try to send an
acknowledge, the RF transmissions of these acknowledges will collide.
If Automatic Acknowle dge Random Delay flag is on, for 2
DataReaders there's a chance of 25% for collision, for 3 DataReaders
35%, and for 4 DataReaders or more the probability rises to about 50%
or more.
The manual acknowledge is a normal RF command initiated by the
application. Note that DataSealLib sends this command by default when the
application gets the Burst messages from a DataReader (using the
Reade r.GetBurstMessages method), but you have the opportunity to
cancel it, and/or send it when most appropriate to you. See the online
documentation for more information.
The advantages of the manual Burst acknowledge are:
- 212 -
Hi-G-Tek Ltd. Microelectronics & Asset Tracking Technology
Chapter 8
System Parameters and Comm ands
The application may send the acknowledge after it has written the
message to a database. This ensures that no data will be lost even in
case of application crash or DataReader's reset.
The application can send only one acknowledge to every burst message
even if many DataReaders received it or more than one retry was
received.
The application can choose the most appropriate timing for sending the
acknowledge.
The disadvantages of the manual Burst acknowledge are:
Because it is a normal RF command it takes the 3 seconds of the
Reader Interrogation Header (Thw).
It is not automatic. Nevertheless, DataSealLib sends it automatically by
default.
Note that more than one DataReader may receive the same Burst message,
and that each DataReader may receive more than one retry of the same
burst message. It is the application's responsibility to correlate equal Burst
messages.
There are 2 formats of Burst messages: one is older, an always include d
only the Short Status of the DataSeal. T he new format can include any
parameter and/or User Data. See the description of the Ale rt Burst Data
Descriptor, Close Burst Data Descriptor and the arguments of the Start
Force d Burst RF command for information about how to define which
parameters and User Data will be included in each type of message. In
addition, the new format includes a sequential number for each event that
caused a Burst message. T his way you can easily correlate messages that
are received by different DataReader, or 2 retries of the same message. T he
Force d Burst messages also contain a special Use r Code argument that the
user can use to define the purpose of the Burst message. In DataSealLib,
you receive the Burst messages through the Reade r.BurstEx event, and

DataSealLib also provides several Boolean or enumerated properties that
reflect specific flags of this parameter:
Carrie rSense – Determines whether the DataReader will make sure that
the RF is clear before starting transmitting a command. Use this flag when
there are DataReaders that are not connected to the same controlling
computer to avoid RF collisions. In synchronized systems this flag should
be off to ensure that the timings are deterministic.
AllowBurst – Determines whether the DataReader will listen for Burst
messages while it is not executing another RF command. If this flag is on,
you have to check for the Burst messages that the DataReader received
using the Reade r.Ge tBurstMe ssages method.
Powe rCalibrationMode – Because temperature changes affect
transmission power, it is required to perform a temperature test and power
calibration process every once in a while. This property determines the
terms in which the DataReader will perform those operations. See the
online documentation for further information about the different options.

Comm and Chain
As mentioned before, setting Thw and Tw to smaller numbers reduces the
response times, but shortens the batteries' lifetime. Even though the default
3 seconds is mostly a reasonable response time, when you have to send
many RF commands, it can accumulate to a lengthily time. The Command
Chain feature allows to execute many RF commands in a row with a single
Reader Interrogation Header (one Thw). The battery consumption of all the
DataSeals that are in Normal Mode (not in Deep Sleep or HF Disabled),
even those that are not addressed by any command in the Chain is exactly
- 230 -
Hi-G-Tek Ltd. Microelectronics & Asset Tracking Technology
Chapter 8
System Parameters and Comm ands
the same as it would if these commands were executes normally one after
the other, but now that consumption is at a shorter period. However, in
times that there are no transmissions, the battery consumption is normal
(unlike the result of using a small Thw and Tw).
Commands can also be adde d to the Command Chain on the go, when you
want to perform a command as a result of the response or responses that
you received in a previous command. For example, suppose that you want
to perform a Se t command to all the DataSeals that their User Paramete r 1
contains the string "READY". You can do it by initiating a Command
Chain with only a broadcast Ve rify command that asks for the Use r
Paramete r 1 parameter, and after receiving the results and examining the
content of the Use r Parame te r 1 parameter, you add the Set command
with the list of Seal ID's of those DataSeals that their Use r Paramete r 1
parameter contain the string "READY".
Note that all the DataSeals that receive the Reader Interrogation Header of
a Command Chain keep listening to all the commands, which consumes
battery as if these commands were executed one after the other. For
DataSeals that there are no command for them it means a waste of battery.
There are few things that you can do to avoid it:
1. Make sure that the DataSeals that should not receive the commands in
the Chain are either in Deep Sleep, but usually more appropriate, their
HF Disable d flag is on (for example by using the Slee p Duration
argument of the Ve rify command).
2. If there are DataSeals with different OrgIDs or Departments, and you
want to turn only to one of them, you should turn on the O IDf flag in
the DataReader's SYS parameter.
3. If there are DataSeals with different ADIs, and want to turn only to a
specific group, you should turn on the ADIf flag in the DataReader's
SYS parameter.

Verify that the Power LED blinks during power on. The LED
should then remain steadily green.
Verify that the cables are connected according to the diagrams in
chapter 5.
Verify that the Reader ID you specified is the same number as the
S/N printed on the sticker on the back side of the DataReader
(below the barcode).
Verify that a terminator exists at end of the RS-485 chain, as
described in chapter 5.
Make sure that the specified COM port is the COM port that in fact
the DataReader is connected to.

low. Putting the DataSeal too close to the DataReader's antenna
(few centimeters) may causes signal distortions.
Verify that the antenna is connected properly.
Verify that the SD/RD LED of Channel 2 is red for a about 3
seconds (with default Thw) upon receiving the command from the
controlling computer, and then turns green for a short time.
The DataSeal may be in Deep Sleep mode. Try to execute a Hard
Wakeup command.
Make sure that the ADI and De partment parameters in the
DataReader are either 0 or the same values that should be in the
DataSeal.
If you can communicate with the DataSeal using a Low Frequency
device (DataT erminal or DataPort), make sure that the ADI,
OrgID and De partment parameters match those of the
DataReader. Also make sure that Tw is appropriate for the Thw in
the DataReader. See chapter 8 for information about Thw and Tw.
Make sure that the HF Disable d flag is off too.
The Ve rify parameters are invalid. See chapter 8 for information
about the parameters of the Verify command.
