The headsets will prompt "Connected," and the Host will dislay the text "NFC SUC" in green, indicating suc- cessful pairing. 4. The headset blue light being constantly on indicates a successful pairing. Group Mode Group Mode Groups Click the "ABC Button" to toggle between Group A, Group B, and Group C. Group A can only communicate with members within Group A. Group B can only communicate with members within Group B. Group C can only communicate with members within Group C. Host can double-click the "A Key" to switch to the ALL group, allowing listening to any subgroup and communicating with anyone within that group.

Pairing 3. Select the serial number you need on the Host end *Serial numbers displayed in black indicate that there are Guests online under that serial number. If you choose this serial number for pairing, the system will show an occu- pancy warning. If you proceed with pairing forcefully, the Guest under this serial number will disconnect and require re-pairing. Pairing 4. After successful pairing, a prompt will indicate "Pairing Successful." If you receive a pairing failure prompt, repeat the previous steps. 5. Once pairing is successful, click the "C" button to return to the Host interface. HUB HUB Cascading One Host can connect to maximum of 7 Guests. More pairing needs to be realized by adding HUB, HUB can realize infinite cascading, support up to 26 sets of simul- taneous use.

Application Note AN-181 Version 1.0 DHAN-Based Printed Antenna Performance January 2016 DSP Group Confidential 1/4 Abstract This document describes the dimensions and the results of simulation, measurement and radiation pattern testing for a DHAN-based printed antenna. Table of Contents 1. Overview ...................................................................................................................................................... 2 2. Measurements and Results ........................................................................................................................... 3 2.1 Antenna Dimensions ............................................................................................................................. 3 2.2 Radiation Pattern Visualization ............................................................................................................ 3 2.3 Simulation............................................................................................................................................. 4 2.4 Radiation Pattern .................................................................................................................................. 4 AN-181 DHAN-Based Printed Antenna Performance Version 1.0 January 2016 DSP Group Confidential 2/4 1.Overview This document describes the mechanical requirements for a DHAN-based printed antenna, and presents simulation, measurement and radiation pattern results. Since antenna performance improves as the GND reference area increases, performance is expected to improve after the antenna is embedded in the larger application/sensor PCB. Since antenna performance is affected by the final application/sensor casing material (i.e. plastic), final antenna matching should be done after the module/antenna is enclosed in its final casing. Contact DSP Group [email protected] for the DHAN printed antenna database (layout & Gerber).
