COMPONENTS
The hardware of a TagMaster system is described briefly below.
6.1 Communicators
The S1566 Reader is a device for reading and writing ID Tags using 2.45 GHz microwaves. It is
powered with 12 VDC but can be adopted for 24 VDC. The S1500 has built-in antennas for
communication with the Tags and various serial interfaces for communication with a host
computer. The Reader also provides a movement detection function which can detect moving
objects in the reading zone (also non-Tagged objects). One hundred frequency channels are
available. The microprocessor is a 16-bit Hitachi H8/534. Originally designed for mounting
under a moving train, it will withstand extremely harsh environments. The S1566 has a 2Wire
RS485 and RS232 interface.
6.2 ID
Tags
An ID Tag is a device carrying ID information that can be read at a long distance using
microwaves. Versions that can be read at a distance of up to 8 meters with the Reader S1503 are
available. The actual reading range, depend on the Reader type. Also different shaped versions of
the tags are available. Some have the shape of a credit card but is slightly thicker. Each Tag has
its own unique 8-digit mark. It is possible to read many Tags concurrently. To maintain the
information, to get the long reading range and the high communication speed, a lithium battery
cell is used. The life of the cell is depends of the Tag type but is typically 5 - 10 years and
independent of how often the Tag is used. Certain types of Tags (e.g.
ScriptTag S1251
) can also
be written by the user. The Tags then have a static RAM memory array that can be configured
for different memory sizes; 14, 154 or 574 bits (32 bit checksum not included in these figures).
Refer to the Tag (e.g. S1251 or S1450) data sheet for details.
