5. Operation
5.1. Power Up
Before running the device it is necessary to connect it to the network compliant with IEEE 802.3af
PoE standard. As soon as the device gets power it attempts to get IP address from DHCP server.
READY LED blinks at that time. If DHCP server is not found the device assigns static IP address to
itself. Default static IP address is 192.168.0.101. This address can be changed by the user with
supplied Bed Watcher Test Utility. After the device has its own IP address READY LED becomes
green and the device starts monitoring continuously.
5.2. Turning the Device On and Off
In order to turn the device on and off it is necessary to plug in or plug off UTP cable to the network
compliant with IEEE 802.3af PoE standard. There is no power switch located on the unit.

5.4. Reading Device Status
Bed Watcher device status can be read via ETHERNET RJ45 socket located on the bottom side of the
device. When STA or AP network mode is enabled the device operates as a TCP/IP server and
responds on requests from client applications according to the data exchange protocol described in a
separate document. When TERMINAL network mode in enabled, the alarm status is signaled by
closing NO1 and NO2 contacts, which remain open at no alarm conditions.
6. Configuration Options
The Bed Watcher has minimum number of parameters that can be configured. Bed Watcher Test utility
for Windows must be used in order to read device settings or program new device settings. Its main
window is shown on Figure 5.

Prior using the utility you must connect it to a Bed Watcher device using Connect menu item from Device
menu or corresponding toolbar button. Use Network port and specify IP address of the device. The device
must either have received the IP address from DHCP server in your network or have assigned static IP
address to itself. The default IP address is 192.168.0.101.
If the connection is successful, you will be able to read current device settings by pressing on the screen
buttons. Pressing on the “Get…” buttons does not change settings in the device. Pressing on the “Set…”
buttons makes changes in the device configuration; therefore it must be done with caution.
Below you can read description of the utility buttons:
Get Device ID, Get Device Name, Get Device Class, Get HW Version, Get FW Version - these buttons
let you get information about the device.
It is strongly recommended start communication with the device by pressing on Get Device ID button for
making sure the device responds on the utility requests.
Get Data - this button reads current device status, including collected information about the monitored
object. The following data fields are being read:
Input Voltage, mV - shows the device power status. Input voltage shall not go down below 5400
mV. If it happens there may be an issue in the power circuit and the device must be inspected and
probably repaired. Correct device operation is not guaranteed at the input voltage lower than 5400
mV.
Current Load, mA - shows the device power consumption. It shall not exceed 500 mA. If it
happens there may be an issue in the power circuit and the device must be inspected and probably
repaired. Correct device operation is not guaranteed at the current load greater than 500 mA.
RF Voltage, mV - engineering parameter. Shall be ignored by the user.
MCU Temperature, ºC - shows the processor temperature. MCU temperature shall not exceed
85 ºC. If it happens there may be an issue in the power circuit and the device must be inspected
and probably repaired. Correct device operation is not guaranteed at the MCU temperatures higher
than 85 ºC.
VCO, MHz - engineering parameter. Shall be ignored by the user.
Energy, units - displays level of activity in the monitored premises.
Respiration, bpm - displays calculated breathing rate in breathes per minute. This value is not
accurate though and shall not be considered for decision making.
Pulse, bpm - displays calculated pulse rate in beats per minute. This value is not accurate though
and shall not be considered for decision making.
Alarm Flag - when set indicates no activity in the monitored premises.
Alarm Duration, s. - displays number of seconds passed since the Alarm Flag was set
Presence Flag - when set indicates activity in the monitored premises. Opposite to the Alarm Flag.
Presence Duration, s. - displays number of seconds passed since the Presence Flag was set
Motion Flag - when set indicates strong movement in the monitored premises. Can be set together
with Presence Flag only.
Motion Duration, s. - displays number of seconds passed since the Motion Flag was set
Run Cycle - this button enables the utility reading the data periodically from the Bed Watcher device. The
value on the right side from the button sets the poll period in seconds. The shortest poll period value is
1 second. Each poll is equivalent to the Get Data button tap.
Set UltraScope mode - engineering button. Switches off the device operation until it is rebooted or
controlled by the UltraScope engineering software.

Reset Device - forces the device to be rebooted. This button does not help when the device is in
UltraScope mode.
Set Bootloader - forces the device to stop normal operation and enter in bootloader mode for updating the
firmware. Please read section 7 of this User's Guide for details about updating the firmware.
Check FW Update - forces the device to stop normal operation and poll specified IP address for firmware
updates. The utility will offer the user to perform the update when a new firmware file is found.
Get Range - reads maximum device operating range in cm. The device is not capable to detect an object
beyond this range.
Set Range - programs the device maximum operating range in cm. The device is not capable to detect an
object beyond this range. The value is taken from the edit box below the Set Range button.
Operating Range Criteria - selects the criterion which defines operating range. Sensitivity defines the
range for breathing detection. Visibility defines the range for motion detection. Sensitivity range is
always shorter than visibility range.
Get DSP Params - reads the device settings that affect on Alarm, Presence and Motion Flags appearance.
Set DSP Params - programs the device settings that affect on Alarm, Presence and Motion Flags
appearance.
The following DSP Params can be read or programmed:
Sampling Rate, Hz - read-only value - specifies
Noise Threshold, units –specifies sensitivity of the device. The smaller value of the threshold –
the higher sensitivity has the device in terms of live object detection. On the other hand, setting
the threshold too low will make the device over sensitive and the device will be detecting live
objects even in empty premises. Default value is 100 000 energy units.
Motion Threshold, units –specifies device reaction on strong movements. The smaller value of
the threshold –the higher probability that the device sets Motion Flag when the object is detected.
Default value is 10 000 000 000 energy units.
Alarm On Delay, s. –determines degree of confidence for the alarm event. The bigger “Alarm On
Delay” is – the higher confidence of the alarm event. On the other hand, setting “Alarm On
Delay” too big will delay reporting moment about empty premises from the real event further in
time. Default value is 10 seconds.
Alarm Off Delay, s. –reduces probability of false live object detection. The bigger “Alarm Off
Delay” is – the lower probability of the false live object detection. On the other hand, setting
“Alarm Off Delay” too big will delay reporting moment about live object detection from the real
event further in time. Default value is 10 seconds.
