2.1
2.1.1
OPERATIONAL DESCRIPTION
Tagging System
The main function of the system is to monitor and control equipment, assets and people in an area or building
in terms of position. This is done by active tags that each transmits a unique ID within a pre-set time interval.
Multifunction readers, appropriately situated in the area where position monitoring has to be conducted, interpret signals transmitted by the tags. All tags interpreted by a specific reader are in fairly close proximity to the
reader; enabling the position of the tags to be established quite accurately.
The system can also monitor movement of equipment. This function is implemented by using tags designed to
sense movement.
2.1.2
Tags
2.1.2.1 Basic Tag
The basic tag can be configured to send its unique ID at a pre-set time-interval. This tag is usually used on
equipment where the position should be monitored. A Tag Programmer is used to externally configure the tag.
The tag is capable of transmitting its ID up to a distance of 5m. It must be however be emphasised that the
transmission range may vary from environment to environment.
2.1.2.2 Tag with movement sensor
The tag with movement sensor senses movement. It transmits its unique ID at pre-set intervals, but will go into
alarm mode automatically when it senses disturbance. This type of tag is generally used on assets that should
not be moved, or subjected to vibration, in normal circumstances. The tag is capable of transmitting its ID up
to a distance of 5m. It must be however be emphasised that the transmission range may vary from environment to environment.
2.1.2.3 Slimline Tag
The slimline tag can be configured to send its unique ID at a pre-set time-interval. This tag is usually used on
equipment and people where the position should be monitored. A Tag Programmer is used to externally configure the tag. The tag is capable of transmitting its ID up to a distance of 10m. It must be however be emphasised that the transmission range may vary from environment to environment.

2.2.2.2 Tag with movement sensor
The tag with movement sensor can be attached to assets, equipment, and people. It is used to perform the
following functions in the system.
•
Transmit its unique pre-programmed ID at a certain pre-programmed time interval.
•
Transmit its unique pre-programmed ID each time that the tag senses movement.
2.2.2.3 Slimline Tag
The slimline tag can be attached to assets, equipment, and people. The tag is used to perform the following
functions in the system.
•
Transmit its unique pre-programmed ID at a pre-programmed time interval.

3 INTERFACE DESCRIPTION
3.1
BASIC TAG OR TAG WITH MOVEMENT SENSOR
Tags basically have two data interfaces that are explained in the paragraphs below.
3.1.1
RF Interface
Tags are designed to operate in the more commonly known free-bands (403MHz, 868MHz). The typical
power output is less than 100uW.
3.1.2
Programming Interface
Each Tag has to be programmed with specific variables. These variables include time-interval of its transmissions and the tags unique ID. A Tag Programmer is used for this purpose.

4.1
PRINCIPAL OF OPERATION
The principal of operation of the Link-It Tagging System s described in this section. A basic knowledge of the
system is essential before commencing with any installations or implementation. A basic system block diagram is illustrated in Figure 4. Tags A ! N attached to assets, equipment and people are recognised and interpreted by a network of Readers and Repeaters. In larger areas Repeaters are used in conjunction with
Readers to increase the area of operation. In smaller areas one reader will normally be sufficient to read all
tags in that area. Information regarding the relative tag positions is sent via cables from readers to a PC.

TAG TO READER/REPEATER COMMUNICATION
Tag to Reader/Repeater communication is done via a RF channel. The interface is described in paragraph
3.1.1. Tags transmit their pre-programmed ID’s at a certain time-interval. These ID’s are received and interpreted by the Reader/Repeater. Readers/repeaters can be configured filter data received from tags. This
means that only certain tags may be interpreted by the reader/repeater.
Figure 5 illustrates a configuration of two repeaters (Repeater1 and Repeater2), one reader (Reader1) and
12 tags (TagA ! TagL). Repeater2 can be configured to receive data only from tags except for TagE, TagF,
TagG and TagH. All other tags that fall within Repeater2 receive zone will be discarded. However, this type of
Link-It Active Tag

configuration is not recommended, but would rather be used in applications where two different systems are
situated in close proximity of each other as illustrated in Figure 6.

5.1
PROGRAMMING OF THE TAGS
Custom Tag Programming software is supplied to each user and vendor of the Link-It Tagging System.
The Tag Programming Software runs on any IBM compatible PC using a Windows 95 operating system. The
program is installed by running “setup.exe” on Disk 1 of the installation disks. A snapshot of the programming
software is illustrated in Figure 7.
