Depending on their basic features, they belong to different tag platforms:  TM801 – an ID tag with limited I/O and memory  TM802 – an I/O tag with 256 kbit additional memory, several I/Os and real time clock  TM803 – a sensor tag with 256 kbit additional memory, several I/Os, real time clock and a 3-axes motion sensor All tags based on these platforms have the same radio circuit:  TM800 – a tag radio module working in the 2.4 GHz ISM band. The characteristics of the TM800 tag radio module are described in section 2 of this document. The tag platforms are the basis for the characteristics of the various Tag products in the RFIDS™ family, but they vary in form-factors, sensors, user-interfaces, battery types and actuators. For instance the TM801-200 Samui is an ID tag in small form-factor with flanges and without any additional sensor, while the TM802-CLZ Edam has calendar function, LED indicator and a buzzer in a card shaped enclosure. Tag specific product information is given in section 3 of this document. 1.2 Introducing RFIDS™ Active RFID technology has the ability to cater for a broad range of needs in the areas of managing assets, environment and people. These may include:  Ensuring assets are not damaged or stolen  Knowing location and status of asset Figure 1 - Tag platforms of the TM800 series TID = Tag Identifier UDS = User defined string I/O = Input/Output interfaces RTC = Real Time Clock XM = Expanded Memory

For this reason, TagMaster has named its active RFID technology ‘RFIDS™’, which stands for ‘Radio Frequency Identification & Sensing’. TagMaster’s RFIDS™ product line is an active RFID technology designed to meet a broad scope of requirements. Apart from identification, this may include tracking of movements, status verification, data retrieval, positioning, security alert, sensing, data collection, sensor logging, sensor alerts and actuation of events. Such requirements often demand reliable operation in tough environments at a variety of ranges, typically 3 to 150 metres, and uncontrollable orientations. They may also include requirement tags to perform useful tasks autonomously and independent of a reader. To meet such broad scope of requirements, while maintaining very good cost-effectiveness and optimal power prudence in all cases, the RFIDS™ is scalable from an ID tag to advanced sensor and actuation tag. In all variants of RFIDS™, the radio module is the same. The design has built-in expandability with sensor and actuation interfaces, additional memory, security, user-interface, and high accuracy calendar functions. RFIDS™ makes use of TagMaster’s Fast RFID Air Protocol (FRAP), which can adjust its payload, i.e. the useful information transmitted from tag to reader and from reader to tag, according to type of tag and/or on a needs basis. For instance, a simple ID tag will indicate to the reader that it is a simple ID tag and only include in its payload what is absolutely needed at that particular point in time. This is important order to minimise duty cycle and thereby improve both anti-collision and battery life. An advanced sensor-tag, on the other hand, might at times require an extended payload to communicate sensor values, alerts, performed actuations and tag status. In the RFIDS™ system, the FRAP allow all types of RFIDS™ tags to co-exist and be read by the same readers without any confusion. The reader or application does not need to keep long lists of tags for sorting and filtering purposes. Instead, each tag will tell the reader what type of tag it is and what its payload contains. 1.3 Operating principles of RFIDS™ Information from the RFIDS™ tag is sent in ultra-short bursts, whose packets are merely 32 bytes long. Figure 2 – Information packets sent from tag Of the 32 bytes, 8 bytes contain security information and a checksum, 5 bytes contain the TID, 1 byte is a payload selector and 18 bytes contain the actual payload.
Date: 27 February 2012 Revision 001 DRAFT © 2011-2012 TagMaster S/B Page 4(8) For tags that do not need to send anything more than their TIDs, the payload is often blank. However, often it will contain the status of the tag, for example the status flag and battery level. Information packets can be either:  Time-triggered, i.e. a packet is sent every blink interval.  Sensor triggered, i.e. a packet is sent when a sensor value or several sensor values are meeting certain criteria.  Reader triggered, i.e. the tag listens for a reader and only sends a packet when it has found a reader sending a wake-up signal. This is called RTF mode (reader talks first). In addition, the RFID’s tags have a special streaming mode, which is used for reading out large amounts of data from the tag or writing data to the tag. This is used for instance when reading out a sensor log. 2 The TM800 tag radio module 2.1 Introduction The TM800 tag radio module is used in the TM801, TM802 and TM803 tag platforms. 2.2 FCC Statement for the TM800 tag radio module The device complies with Part 15 of the FCC Rules.
