Hi-G-Tek Ltd. Microelectronics & Asset Tracking Technology 16
The Hi-G-Tek range of products provides a highly reliable and secure
cargo and asset monitoring system utilising state-of-the-art RFID
technologies.
1.1. About the Product
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 DataSeal is a sophisticated device, which includes a
transmitter/ receiver unit, real-time clock, processor, memory
and sensing circuitry for sealing verification. The Sealing Wire
prevents any attempt of opening, bypassing or tampering with the
seal without alerting the system and recording of the event. The
system combines the technological and operational advantages of
both low frequency close-range data management AND high
frequency long range sealing verification and automatic data
collection.
DataSeal's ability to log data and communicate it through a
Handheld DataTerminal is best used In low frequency/short range
applications. This way the electronic manifest of the sealed cargo
can be written into the DataSeal's memory. The information includes
Vehicle ID, container and invoice numbers, cargo description,
quantities, destination, etc. Capable of logging up to 55 events, the
information can be downloaded into a computerised database for
storage and processing.
Cost-effective, more reliable and more secure than their mechanical
counterparts, the Hi-G-Tek product range will constantly
monitor your assets and alert you to any potential problems
at all times.
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.
Thank you for choosing Hi-G-Tek quality products.
Introduction

Hi-G-Tek Ltd. Microelectronics & Asset Tracking Technology 17
When used in high frequency/long range applications, the DataSeal
is capable of communicating its ID and status to a distance of up to
30 meters. The DataSeal transmits the information in reply to an
interrogation by the DataReader. The ability of the DataSeal to
communicate with the DataReader at long range enables the use
of the DataSeal in 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.
This User's manual includes all the information required for
installing and operating Hi-G-Tek Electronic Seals and
DataTerminals.
The handheld DataTerminal is used for writing information into the
DataSeal's memory at the departure point and retrieving the
information at the destination. Events, logged in the DataSeal's
memory are also downloaded into the DataTerminal for later office
use.
The DataReader is used in long range applications to interrogate the
DataSeals over the high frequency channel for their ID and Status.
The DataReader is also used for writing information into the DataSeal
and retrieving logged information from the DataSeal. Each
DataReader can communicate with numerous DataSeals
simultaneously and verify their presence and status. The DataReaders
can be chained to allow coverage and protection for secured cargoes
in large storage yards and ports. The DataReader has an optional
communication modem which allows the system to transmit the
collected information through available communication channels to
the Control Center. The DataReader is available in both outdoor and
indoor models.
A set of Mounting Fixtures has been developed for the DataSeal
system which allow convenient mounting and removal of the
DataSeal whenever required. The various Mounting Fixtures differ
in the level of protection they provide to the DataSeal as may be
required in various environments.

In the stationary configuration, the unit is mounted on a flat stationary
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 seal at predetermined
sites and checkpoints.
In the mobile configuration, the unit is mounted in the truck cabin.
The DataReader monitors the seal during the entire journey, and reports
its status via the vehicle's communication system to the control center
in real-time.
The DataReader is mastered by a host computer. Once installed, the
unit waits for commands coming from the host computer.
The DataReader may be used in both stationary and mobile
configurations.

Up to 32 DataReaders can be connected in a daisy chain using
RS485. The last reader in the chain should be terminated by a
120 Ohm resistor between the RXA and the RXB.
For the Outdoor version, the user can decide to create either an
internal or external termination switch. The internal termination
switch is created by setting to ON the termination switch (S2) of
the last reader in the daisy chain.
An external termination is relevant for the Indoor version only. An
RS-485 to RS-232 adapter termination should be provided for the
adapter receive channel.

3.5. Power Supply Requirements
The DataReader supply voltage is chosen according to the
model, either 12V, 24V or 48V.
Power supply wattage: each Reader consumes maximum 1.7W,
so the power should tolerate the number of Readers in the chain
multiplied by each Reader's power consumption.
EXAMPLE: 10 Readers connected in a daisy chain require
10X1.7=17W power supply.
Note that if the power supply is installed in a high temperature
0
area (usually above 40 C), there is a derate in power supply
wattage. (Refer to 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.
In vehicular installation, a 1A fuse must be used.
In outdoor and indoor system, the power supply should be installed
indoor. For outdoor system, approved power supplies are:
For Indoor system, the power supply should be UL1950 approved.
A desktop style with IEC320 inlet is recommended.
When power supply cable ends are connected directly to system cable,
a proper isolation should be made. Using heat shrink tube is
recommended.
3.6. Cable Selection
The cable is used for power supply to Readers in a chain and for
RS-485 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.
DataReader Installation
3
Hi-G-Tek Ltd. Microelectronics & Asset Tracking Technology 45
Example:
A setup of 10 DataReaders with 20 meter 24AWG cable between
Readers and 24v supply to the first Reader
The ohmic resistance between Readers 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 Reader in the chain.
This is below Reader specification of Reader minimum supply voltage.
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 readers in chain. Calculation of voltage
drop in a certain setup should be done, in order to avoid this.
In most cases, the solution for such problems includes , connecting
a pair of wires for the supply ( 2 for supply and 2 for return), using
thicker cable, or using higher temperature rated cable.
Environmental considerations: In an outdoor installation ,the cable
should withstand all outdoor conditions, that is water proof,
temperature,ruggedness etc.
Cable connection:
1 pair for RXA and RXB signals.
1 pair for TXA and TXB signals
SIGNAL 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).
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 Reader
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.
