Safety Information Read and follow all instructions before using the Model 2112 Tag when it has been incorporated into an end product. The following are typical safety instructions for a PLUS Tag that would apply to an end product using the 2112 Module. • Do not use the Tag if it has been damaged. • Do not install in environments that exceed temperature and humidity requirements. • Do not leave the Tag on a heat source.

Introduction The Plus Model 2112 Modular Tag is a complete PLUS UWB Tag design for integration into a PLUS printed wiring assembly (PWA) and enclosure, and connected to a power source. It has the following features: • Runs from a 3 volt DC power source (can operate down to 2 volts DC) • Will transmit a UWB packet at a rate set at time of manufacture. Rate can be set to 1Hz, 6Hz, 8Hz, 10Hz, 15Hz or 20Hz. • Meets FCC Section 15.212, rules concerning single modular transmitters.
Overview Background Tag tracking is accomplished by analyzing time-differences-of-arrival (TDOAs) of tag transmissions. When a tag transmits a packet, PLUS ® Sensors that successfully receive the packet will send out information concerning the tag packet, including a precise timestamp. The difference in the timestamp between sensors gives the TDOA for that sensor pair/tag combination. At least three sensors must hear a tag in order to determine a valid position for that tag.
Specifications Housing Material Housing design varies to meet end user requirements. Housing material will vary and may include ABS, Polycarbonate, HDPE, Silicone, or Rubber. Power Source 3V DC (can work down to 2V DC) Ingress Protection Dependent on User enclosure design Compliance FCC Part 15 15.519(c) / 15.209 15.519(d) 15.519(b) 15.519(e) EU Standard EN 302 065-1 V1.3.1 (2013-06) EN 302 065-1 V1.3.1 (2013-06) EN 301 489-33 v1.1.1 EN 301 489-1 v1.9.
Mounting Depending on end user requirements, mounting methods will vary. Identification Per FCC Section 15.212: The 2112 Tag FCC identification (ID) will be printed via the silkscreen on the TOP side of the board. Figure 1-1 below shows the FCC ID as it appears on the bottom of the board right above the PLUS copyright and PWB identification: Figure 1-1 FOR THE USER IMPLEMENTATION OF THE 2112 TAG: Per FCC Section 15.
FCC Section 15.212 Compliance The PLUS 2112 Tag complies with FCC Section 15.212 rules concerning single modular transmitters in the following: 15.212 (a) REQUIREMENT: “Single modular transmitters consist of a completely self-contained radiofrequency transmitter device that is typically incorporated into another product, host or device.
15.212 (a) (1) (ii) REQUIREMENT: “The modular transmitter must have buffered modulation/data inputs (if such inputs are provided) to ensure that the module will comply with part 15 requirements under conditions of excessive data rates or over-modulation.” IMPLEMENTATION: The 2112 Tag circuitry transmitter drive from the microcontroller is a logic gate providing a fixed drive that will not overdrive the burst mode oscillator transmitter.
15.212 (a) (1) (v) REQUIREMENT: “The modular transmitter must be tested in a stand-alone configuration, i.e., the module must not be inside another device during testing for compliance with part 15 requirements. Unless the transmitter module will be battery powered, it must comply with the AC line conducted requirements found in §15.207. AC or DC power lines and data input/output lines connected to the module must not contain ferrites, unless they will be marketed with the module (see §15.27(a)).
15.212 (a) (1) (vi) (B) REQUIREMENT: Electronic display of FCC identification number. IMPLEMENTATION: Not applicable, since the 2112 Modular Tag will not be installed in any product that has an electronic display. 15.212 (a) (1) (vii) REQUIREMENT: “The modular transmitter must comply with any specific rules or operating requirements that ordinarily apply to a complete transmitter and the manufacturer must provide adequate instructions along with the module to explain any such requirements.
15.212 (b) REQUIREMENT: “Limited modular approval also may be granted in those instances where compliance with RF exposure rules is demonstrated only for particular product configurations. The applicant for certification must state how control of the end product into which the module will be installed will be maintained such that full compliance of the end product is always ensured.” IMPLEMENTATION: The 2112 Modular Tag will: • Not have shielding over the radio elements of the circuitry; 15.
Example Figure 1-2, below, shows an example of a 2112 Module integrated onto a PWA for potential use in an end product. This example is one of several possible PWA’s PLUS could put the 2112 Modular TAG circuitry per the controlling PLUS documentation. Figure 1-2.
