Local communication mode
In local communication mode SCA11H connects to pre-defined WiFi network.
• SCA11H sensor node works as TCP/IP-server and writes output data in ASCIIformat in the defined IP-address port 8080
• Simple Service Discovery Protocol SSDP is used for device discovery
• Sensor node can be calibrated and maintained using the HTTP API according to
SCA11H Hostless WLAN HTTP API Specification 82218200.

4 SCA11H installation
4.1
Positioning SCA11H into the bed
Positioning of SCA11H is very important. Please note two main items:
1. Orientation of the SCA11H needs to be the same as printed on top of the node
(head to toes)
2. SCA11H measures the bed vibration caused by blood circulation and therefore it
needs to be positioned in a place most optimal to measure this vibration.
Figure 4 depicts possible positioning options for SCA11H.
1. Under the mattress pad. Do not place under a person but rather on the side or
edge of the mattress. The recommended distance to the person to be measured is
min 20 cm.
2. On the bed frame or
3. On the side of the bed
Figure 4. Position options for SCA11H
In addition the socket-outlet shall be installed near the equipment and shall be easily
accessible.

4.2
Setting SCA11H into configuration mode (Appendix 1)
1. Ensure power is disconnected
2. Remove SCA11H from the attachment plate (attachment plate is the black plate
attached with magnet to actual SCA11H sensor node, please see the figure below)
3. Plug in the power
4. Wait about 5 s until the green power led starts to blink with 1s interval
5. Attach SCA11H sensor node to the black attachment plate
6. After steps 1-5 SCA11H is ready for positioning and configuration.

Configuration (Appendix 1 and 2)
1. Connect the used configuration device (for example laptop) to SCA11H's
configuration network: muRata_CFG_XXXXXX using password: 24681012.

4. Select “BCG Mode” for algorithm data output or “Data Logger Mode” for raw
data output.
5. Select “Normal” as measurement direction.
6. Click “Apply” if changes were made.
Remark: Do not modify calibration parameters manually without in-depth understanding!
Select Communication Settings tab

7. Select “Local Mode” if you are operating in local network or “Cloud Mode” if
data is sent to a cloud server.
8. If cloud mode is selected, please follow the service provider instructions to
configure the parameters.
9. Click “Apply” if changes were made.

Calibration
Calibration is recommended to be carried out separately for each person in bed. If the
person in bed changes, calibration should be repeated in order to obtain reliable results
for each person.

Select Bed Sensor Settings tab
Figure 11. Calibration
1. Make sure that the SCA11H is positioned as instructed in chapter 4.2, bed is
empty and it is not exposed to disturbances.
2. Start the empty bed calibration by clicking the “Start” button. This takes 1
minute. In case of disturbances the calibration can be started again. When
succeeded, bed has been calibrated to the environment.
3. After empty bed calibration has been successfully performed SCA11H can be
calibrated for the occupied bed. The monitored person should lie still on the bed
and the occupied bed calibration can be started by clicking the “Start” button.
This takes also 1 minute.

5 Testing the output of SCA11H
When using SCA11H the first time with the specific bed it is recommended to ensure
proper sensor position. Please use e.g. separately provided BCGDemoGUI to verify the
measured raw data contains periodic signal due to pulse. If no periodic signal can be
seen, sensor position should be improved.
6 Care Instructions and Safety Utilization
SCA11H is maintenance free. AC-adapter must be disconnected from the power when
cleaning the bed to avoid electric shock due to water or moisture.
SCA11H does not need to be reconfigured or recalibrated in case of power out.
7 Declarations
- SCA11H operating temperature range is 10 to 55 °C
- Non-authorized modification by user is prohibited.
- SCA11H sensor is not a medical device and has not been validated or approved as
such. It should not be used to diagnose or treat medical conditions.
