Default settings
By default, data provided in event driven mode. Which means that sensor sends the data when motion or respiration detected. The message after first detection is sending during 1 second. For continuous event sensor sends messages with delay around 3 second.
In case of no detection, sensor sends zero values every 1 minute to indicate that sensor is “online”.
Data format is ASCII and represented as “val1, val1”. Default communication speed is 9600 bps. Default sensor’s ID is 0x00.
Optional settings
Parameters of serial communication can be adjusted as follow:
– Communication speed: 1) 9600 bps. 2) 57600 bps. 3) 115200 bps. 4) 230400 bps.
– Sending method: 1) Event driven. Sensor sends the data when motion or respiration detected. The message after first detection is sending during 1 second. For continuous event sensor sends messages with delay around 3 second. In case of no detection, sensor sends zero values every 1 minute. 2) Continuously sending. Sensor sends the data continuously with fixed time interval from 1 to 180 seconds. 3) By request. Sensor sends the data when host request it.

Rev. 1.7 umain.co.kr

P a g e 10 | 26

– Data format: 1) ASCII. Data format is represented as “val1, val1” (in C: printf(%d, %drn, val1, val2); ) val1 is movement value and respiration value.

In the figure above, the received data is in ASCII format, left values 362, 481 are movement values, and right values 0 are respiration values. Respiration is zero because it is an environment that measures the state of movement.
2) Hex format. Data is packed in message that contains header, sensor id, motion and respiration markers and checksum:
0x6A Sensor ID 0xC1 Value 1 MSB Value 1 LSB Value 2 CRC8

Rev. 1.7 umain.co.kr

P a g e 11 | 26

In the figure above, the data received is Hex format. For example “6A 00 C1 01 14 00 84” data has been received

1. 6A is always a common type of sensor 2. 00 is a default sensor ID (selectable, ref. P17) 3. C1 is alarm signals that the sensor has detected movement or respiration 4. 01,14 is the value of movement value 5. 00 is the respiration value 6. 84 is a CRC8 value

Manual Information to the End User:
· The OEM integrator has to be aware not to provide information to the end user regarding how to install or remove this RF module in the user’s manual of the end product which integrates this module. The end user manual shall include all required regulatory information/warning as show in this manual.
OEM Responsibilities to comply with FCC Regulations
The (your product name) Module has been certified for integration into products only by OEM integrators under the following conditions:
1. The antenna(s) must be installed such that a minimum separation distance of 5mm is maintained between the radiator (antenna) and all persons at all times.
2. The transmitter module must not be co-located or operating in conjunction with any other antenna or transmitter.
As long as the two conditions above are met, further transmitter testing will not be required. However, the OEM integrator is still responsible for testing their end-product for any additional compliance requirements requiredwith this module installed (for example, digital device emissions, PC peripheral requirements, etc.).
IMPORTANT NOTE: In the event that these conditions cannot be met (for certain configurations or colocation with another transmitter), then the FCC authorizations are no longer considered valid and the FCC ID cannot be used on the final product. In these circumstances, the OEM integrator will be responsible for re-evaluating the end product (including the transmitter) and obtaining a separate FCC authorization.
This modular transmitter is only FCC authorized for the specific rule parts (i.e., FCC transmitter rules) listed on the grant, and that the host product manufacturer is responsible for compliance to any other FCC rules that apply to the host not covered by the modular transmitter grant of certification. If the grantee markets their product as being Part 15 Subpart B compliant (when it also contains unintentional radiator digital circuity), then the final host product still requires Part 15 Subpart B compliance testing with the modular transmitter installed.
Host labelling guidance for the end integrator
This is an advise for host manufacture to provide a physical / e-label on their host product stating, “Contains FCC ID: 2AN8QUM80M”: A permanently affixed label must be used. The modular transmitter must be labeled with its own FCC identification number, and, if the FCC identification number is not visible when the module is installed inside another device, then the outside of the device into which the module is installed must also display a label referring to the enclosed module. This exterior label can use wording such as the following: “Contains Transmitter Module FCC ID: 2AN8QUM80M ” or “Contains FCC ID: 2AN8QUM80M “.
