2 SCA11H operation modes
2.1 Configuration
In configuration mode SCA11H creates its own network.
Following configurations and settings can be made using configuration WEB page.
1. Communication – local vs cloud
2. BCG measurement related settings
3. Network settings
4. BCG-calibration
Figure 2. Configuration WEB page
2.2 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 808 0
• 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 822 18 200 .

3 SCA11H user interface
After initialization with the attachment plate LEDs on the top indicate the following
functions:
1. Power (green)
x Blinking: connecting to network
x Static on: connected to network
2. Network (orange)
x Flash: network traffic (transmission or reception)
3. Status (green)
x Flash: BCG data transmission
After initialization without the attachment plate (approx. 10s) LEDs indicate the following
functions:
1. Power (green)
x Blinking: configuration mode
2. Network (orange)
x Flash: network traffic (transmission or reception)
3. Status (green)
x Off

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.
