3 1. Hardware Description BLOCK DIAGRAM OF DT357 BLOCK DIAGRAM OF DT357-UFL PROCESSOR The DT357 series module utilises an Ember EM357 S.O.C (System on Chip) which has an integrated 32-bit ARM® Cortex™-M3 processor, flash (196kB) and RAM (12kB) memory and peripherals. This is interfaced by standard serial wiring (UART) and includes JTAG programming interface. This allows for powerful software debugging and programming of the ARM Cortex ™-M3 core. The EM357 has built in 1.8V and 1.25V regulators as well as a power-on-reset circuit which reduces the amount of external circuitry required. ANTENNA The DT357 module includes an integrated chip antenna (Antenova Rufa) which is compact in size but has a uni-directional radiation pattern allowing a gain of 2.1dBi. Further details of the antenna can be found on the Antenova website. The DT357-U.FL module includes a U.FL connector instead of a chip antenna that allows for the connection of an external antenna up to a gain of 2.0dBi. 24MHz 24MHz JTAG A/D UART RESET JTAG I/O U.FL Connector Ceramic Balun Harmonic Filter Chip Antenna EM357 VBRD Ceramic Balun EM357 Harmonic Filter VBRD A/D UART RESET I/O

8 10. PCB Keep-Out Areas For optimum RF performance when using the DT357 module (Chip Antenna version) the module should be placed so that the antenna is located on the edge of the mating PCB. No tracks or planes or components should be located in the keep-out area. When using the DT357-UFL module (external antenna version) the keep-out area does not need to be adhered to.

9 11. Product Approvals The DT357 and DT357-U.FL have been designed for modular compliance into USA (FCC), Canada (IC), Australia (C-Tick) and Europe (CE). Full FCC, IC and C-Tick compliance have been obtained and European compliance (CE) has been part completed with full compliance to follow in the future. 11.1 FCC Part 15.247 Certification The DT357 and DT357-U.FL modules including the antennas listed in Table 1 below have been tested and have been found to comply with FCC CFR Part 15 (USA). The DT357-U.FL has compliance for an external antenna with a maximum gain of 2.0dBi. To meet the section 12.209 emission requirements in the restricted bands of section 15.205, the transceiver transmitter power for the DT357 and DT357-U.FL modules needs to be reduced from 8dBm to 7dBm on the top channel 1A (2480 MHz). The software Daintree will release with the DT357 and DT357-U.FL modules will limit the end user to a maximum of 7dBm on the top channel 1A (2480 MHz) to ensure compliance. These devices meet the requirements for modular transmitter approval as detailed in the FCC public notice DA00.1407.transmitter. These additional requirements can allow the DT357/DT357-U.FL modules to be installed in a new device without subsequent new equipment authorisation to be obtained. This device complies with Part 15 of the FCC rules. Operation is subject to the following two conditions: (1) this device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation. Item Part No Manufacturer Type Gain 1 S131CL2-L-XXX-2450 Nearson 1/2 Wave 2.0dBi The Daintree DT357 and DT357-U.FL modules have been tested and found to comply with the limits for a digital device, pursuant to part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. The Daintree modules generate, use and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However there is no guarantee that interference will not occur in a particular installation. If the Daintree module does cause harmful interference to radio or television reception, which can be determined by turning the Daintree module off and on, the user is encouraged to try and correct the interference by one or more of the following measures: • Reorient or relocate the receiving antenna. • Increase the separation between the Daintree module and receiver. • Connect the Daintree module into an outlet on a circuit different from that to which the receiver is connected. • Consult the dealer or an experienced radio/TV technician for help. The DT357 and DT357-U.FL modules with their antennas comply with FCC/IC RF exposure limits for general population/uncontrolled exposure. While the applicant for a device into which the DT357 and DT357-U.FL with an approved antenna in Table 1 is to be installed is not required to obtain a new authorization for the module, this does not ensure that some other form of testing may be required for the end product. Any changes or modifications made to this device that are not expressly approved by Daintree may void the user's authority to operate the equipment. When using the DT357-U.FL with approved antennae, it is required to prevent end-users from replacing them with non-approved ones.
10 To comply with FCC and Industry Canada RF radiation exposure limits for general population the antennas used for the DT357 and DT357-U.FL must be installed such that a minimum separation distance of 20cm is maintained between the antenna and all persons at all times and must not be co-located or operating in conjunction with any other antenna or transmitter. 11.2 FCC Labelling Requirements When integrating the DT357 and DT357-U.FL into a product it is necessary that the FCC labelling requirements are met. This includes a clearly visible label on the outside of the finished product specifying the Daintree FCC identifier (FCC ID: Z6G-DT357) as well as the statement above. This label can use wording such as “Contains Transmitter Module FCC ID: Z6G-DT357” or “Contains FCC ID: Z6G-DT357” or similar words which convey the same information. FCC ID: Z6G-DT357 11.3 Canada IC Certification The DT357 and DT357-U.FL comply with Industry Canada License-exempt RSS standards. • Operation is subject to the following two conditions: 1) this device may not cause interference, and 2) this device must accept any interference that may cause undesired operation of the device. • To reduce potential radio interference to other users, the antenna type and its gain should be so chosen that the equivalent isotropically radiated power (e.i.r.p.) is not more than is necessary for successful communication. • This radio transmitter DT357-U.FL has been approved by Industry Canada to operate with the antennas listed in Table 1 with a maximum permissible gain of up to 2.0dBi. Antenna types having a gain greater than the maximum gain indicated for that type are strictly prohibited for use with this device. The antenna impedance required is 50 ohms. The labelling requirements are similar to those of FCC. A visible label displaying the IC number must be shown. The end user is responsible for the final product to comply with IC ICES-003 (Unintentional radiators). 11.4 European Certification The DT357 and DT357-U.FL have been certified to the following standards: • Radio: EN 300 328 v1.7.1 (10/2006) • EMC: EN 301 489-17 v2.1.1 (09/2008). EN 301 489 compliance to be completed in the future. The DT357 will be tested with its integrated chip antenna with a gain of 2.1dBi. The DT357-U.FL will be tested with an antenna listed in Table 1 with a maximum gain of 2.0dBi. The ‘CE’ marking must be applied to a visible location on the user’s product and must be legible.

Customers assume full responsibility for meeting the required guidelines for each country for their product distribution market.
