CONFIDENTIAL Copyright 2017, Salutron, Inc. Revision 0.1 Revision Date: 07/23//17 Page: 4 of 21 Model HRM8700Wireless Heart Rate Monitor Specifications General Description  The Model HRM8700 is a wireless receiver and Handgrip Heart Rate Monitor Combo. It is designed to manage and support ECG contact heart rate and the reception of wireless heart rate data from BLE, ANT+, standard 5kHz chest straps or wearable heart rate transmitters or devices.  Once enabled by the Console, the HRM8700 actively scans for local HR transmitter signals, and supports a user selection/pairing protocol processed by the Console.  Once a HR transmitter is selected/paired, the HRM8700 streams the user heart rate data until the end of the workout session, then ‘unpairs’.  The HRM8700 contact heart rate monitor can quickly and accurately measure the heart rate from an ECG signal under noisy environments.  The HRM8700 simultaneously processes Handgrip Heart Rate and Wireless Heart Rate data. Either can be specified as the priority heart rate. Features:  Direct connection to equipment; no phone device or app ‘middleman’  Support ECG contact heart rate  Supports multiple inbound sources for HR: BLE, ANT+, 5kHz  Automatic proximity sensing to minimizing interference from competing wireless HR signals  Console controllable proximity commands allowing ‘customization’ of the scanning proximity during integration development of the HRM8700 into the console  Simplified user pairing routine  Future-proof: OTA updateable to support future features (based on console pass-through, if available)  Interface: UART, custom command protocol The HRM8700 series combo heart rate module delivers high performance ECG contact and telemetry heart rate monitoring - for both commercial/club and home cardio equipment applications. The HRM8700 communicates and passes the heart rate data from the heart rate monitor to the equipment console through proprietary UART protocol. The HRM8700 series offers a special proximity pairing feature that allows the equipment console to discover only the HR transmitting devices in close proximity. This feature minimizes unwanted devices and speeds up the pairing process, especially useful in health club environments where there may be multiple BLE or ANT+ devices present. After successful pairing, the reception distance will automatically increase to maximum range. The HRM8700 receiver also supports legacy S-pulse contact heart rate and 5kHz chest strap data reception. It utilizes Salutron’s proprietary Digital Crosstalk Control and Digital Noise Filter algorithms that can filter out unwanted competing chest strap signals. This supports better wireless reception and reduce 5kHz noise from potentially unfriendly high ‘noise’ environments coming from power systems and console electronics. o ECG handgrip contact heart rate with R-R interval output (Optional) o BLE smart and ANT+ data reception o Standard 5.3kHz chest strap, coded and un-coded signal reception o Proximity pairing feature. o UART communication protocol o Stationary Bike FE-C support o 3~6V operation. o RoHS compliant.

CONFIDENTIAL Copyright 2017, Salutron, Inc. Revision 0.1 Revision Date: 07/23//17 Page: 11 of 21 2.5. Equipment and HRM8700 Operations The equipment console will send “workout” command to HRM8700 to wake it up from the idle state to scanning state. The HRM8700 will start scanning for 5kHz, BLE and ANT+ HR transmitter advertising within its proximity. The proximity setting is added in the “workout” command send by the console. While in the scanning state, the Contact heart rate is always active to stream contact HR data to the console. The HR transmitter ID that are found during scanning state will be sent to the Equipment console. For BLE, the advertising name and BLE address are sent to the console. A separator key is added in between the advertising name and the BLE address. See the UART package table for the details of communication protocol. All BLE HR transmitter IDs send to the console are uniquely identified. This means there are no duplicate for BLE HR transmitter IDs received by the equipment console. For ANT+ the advertising ID is sent to the equipment console. There is a possibility of duplication of ANT+ HR transmitter IDs because of the limitation of ANT+ protocol in providing certain ID information. For 5kHz, a "5kHz HRM" name is sent. Only one 5kHz HR transmitter is send to equipment console while a maximum five each of BLE and ANT+ HR transmitter are sent to the equipment console for a maximum of eleven HR transmitters. Although the console can receive more than eleven devices, the limitation is due to the capacity of HRM8700 microcontroller. Maximum capacity might change in the future or upon customer request. After all HR transmitter IDs within the pairing proximity range are sent to the equipment console, the user is expected to choose what type of HR transmitter to be used during workout. If the user selects the BLE HR transmitter, the corresponding BLE address is sent back to HRM8700. The BLE address is one of the parameters for pairing and tracking BLE HR transmitter. If user selects an ANT+ HR transmitter, the HRM8700 will use the ANT+ advertising name for pairing and tracking. If there are more than one ANT+ HR transmitter with the same advertising name then there might be a chance for the user to pair to a wrong HR transmitter. For a 5kHz HR transmitter, the transmitter with the strongest signal is expected to be paired. After the HRM8700 successfully pairs with the selected HR transmitter, it starts streaming the heart rate data to the console. The frequency of heart rate streaming will be dependent upon the kind of connected HR transmitter, but for 5kHz and Contact HR it would depend upon the heart rate BPM rate. A special process is implemented if only 5kHz is detected during scanning. By default, the HRM8700 will not wait for user confirmation, but will directly connect to the 5kHz HR transmitter if it is the only one detected during scanning. HR data will automatically be sent to the console after connection. However the console has an option to override it with the “5KHZ disable auto connect” command. In this case the console will wait for user confirmation. The Contact mode can be configured as contact override on or off. It also can stream the R-R interval value after a valid HR is sent to the console. The R-R interval is available in Contact HR mode only if the option is enabled. The equipment console would need to send a “stop workout” command to disconnect the HRM8700 to the paired HR transmitter. The HRM8700 will forget that HR transmitter and go to idle state and wait for the next interaction.

CONFIDENTIAL Copyright 2017, Salutron, Inc. Revision 0.1 Revision Date: 07/23//17 Page: 15 of 21 Appendix A : Grounding and ESD Recommendations Overview For accuracy and performance, the HRM8700 wireless receiver and heart rate monitor (HRM) combo must be properly grounded. Improper grounding introduces unwanted noise that can overwhelm the ECG signals and compromise the signal-to-noise ratio. Improper grounding can also leave the system vulnerable to problems from electrostatic discharge (ESD), which can cause the console to reset. In order to provide a stable ground for the HRM8700 and to protect from ESD, the ground needs to be free of noise and have very low impedance. This application note provides grounding and ESD recommendations based on common installations of the HRM8700. The recommended method provides a dedicated ground for this board. The above solution requires as a prerequisite a good regulated power supply. This is because when the ESD current causes transient on the ground wire, the power supply can regulate and absorb the energy to a certain extent so that it is not propagated to the rest of the system to cause resets. If flat ribbon cable is used as the inter-connect between HRM and Client console, multiple circuits are required for +5V and Return to ensure low impedance. It is also a good practice to use a reliable supervisory integrated circuit for power up and power down management to avoid undesired resets to the microcomputers when ESD occurs. For treadmills, the motor drive design is also critical to ensure an electrically quiet system to meet FCC Class A and Class B compliance. The inductive load creates radiated noise with wide band characteristics that will compromise heart rate performance in acquisition time. (See footnote of ECG Measurement on page 7)

Revision 0.1 Revision Date: 07/23//17 Page: 16 of 21 Wire Return Figure A1: Wire return grounding recommendation A wire return is an effective solution for grounding and ESD protection. However, the impedance in the wire can limit the effectiveness in conducting ESD current. Therefore, it is recommended that a return wire of 16 gauge is used. The wire should be made as short as possible, not to exceed 12 inches. In Figure A1, a return wire is attached directly to HRM at HD1 hole. Because of unwanted noise, do not tie the return wire to the ground (indicated RTN above) from the power supply but to earth ground directly. The return wire connected to the earth ground can be ordered pre-assembled with the HRM8700. See the “Order Information“ section for order details.

CONFIDENTIAL Copyright 2017, Salutron, Inc. Revision 0.1 Revision Date: 07/23//17 Page: 17 of 21 ESD Protection The independent return wire described earlier also serves as an ESD return path when electrostatic discharge occurs. The high voltage protection circuit in the HRM will cause the discharging current to pass through this independent ground path. Therefore, the console is less likely to latch up due to the incomplete reset caused by unpredictable ESD current. The return ground does not conduct current unless ESD occurs. However, when ESD occurs, the ground must have low impedance to discharge the ESD energy. To ensure low impedance, a 16 gauge copper wire is recommended for ESD protection. The length of the wire should not be made longer than 12 inches. The wire should be bolted to the closest spot in the equipment where a reliable chassis ground is available. A dedicated ground plane in the console PCB may help to reduce the chance of latch-up when ESD fires. A good supervisory IC is highly recommended to reduce possibilities of resetting the console, too. The HRM8700 Wireless Receiver and HRM product was tested by HAEFELY PESD3010 system that is certified for IEC 61000-4-2 level 4 for both air and contact ESD tests.
CONFIDENTIAL Copyright 2017, Salutron, Inc. Revision 0.1 Revision Date: 07/23//17 Page: 18 of 21 Appendix B: HRM8700 Placement Guideline The electrical noise generates from the machine could affect the reception range of 5KHZ wireless receiver. It is better to avoid any noise frequency near 5KHZ or harmonics get near the module. Although not all electrical noise can be avoided, the following sources could contribute to the interference. It is recommended to position the HR wireless module as far from these sources as possible.  LED display  Electrical fan  Audio speaker  Magnetic field  Piezo buzzer/beeper  Magnetic brake (Bike)  External/ internal CD player  Excessive ripple noise on power supply  Switching power supply  Motor controller  Sound or noise source in audio band (20HZ~20KHZ)  Cell phone An incorrect wireless coil orientation placement will affect the range. The orientation of the receiving coil on the HRM wireless module should be in horizontal or parallel with the transmitter’s coil to obtain the optimal performance.
CONFIDENTIAL Copyright 2017, Salutron, Inc. Revision 0.1 Revision Date: 07/23//17 Page: 19 of 21 The ideal placement location of the HR wireless module would be at the center, toward the front that is closer to the user, and away from the noise sources. In case the wireless module has to place off to the left or right side from the center of the console, then try to keep the offset distance within 12 inches (30cm) or less, otherwiseThe reception distance of the HRM will be shorten if it is placed too far off from the center. 
