1.1.1. IoT Monitoring products
All SD-xxx devices are IoT Monitoring devices which means they
have to be connected to a SensDesk Technology portal.
All the SMS/email alerts, PDF reports, and central device
management is realized from the portal.
The manufacturer provides a limited free-of-charge portal service
(HWg-cloud.com) and a paid service (SensDesk.com).
You can also check other Portal Providers (your local
distributors) for other available compatible portals.

2. SD-xxx devices product family
The SD-xxx Devices is a family of simple easy-to-install remote monitoring products

2.2. Shared features of the SD-xxx product family
▪Robust metal design, 70×68×34mm d/w/h (without antenna)
▪Ethernet or WiFi - 802.11 b/g/n (2.4GHz)
▪Support for simultaneous Ethernet and WiFi operation (for easy setup)
▪External antenna, SMA connector
▪Plug&Play –connect power and the device is immediately available in the portal
▪Device & communication settings (communication period, Safe Ranges) are
configured in the SensDesk Technology portal
▪Powered from a 5V adapter or PoE
▪Embedded WEB server
For specifics of individual devices, including any differences in the measurement period,
see the respective device page.
2.3. Measurements and data upload
2.3.1. Sensors measurement and data upload periods
The period for logging the measured values and uploading them to the portal is
automatically fully configured by the portal.
2.3.2. Default SensDesk.com portal values
▪Logging period (storing values in the internal memory): 5 minutes
▪Data upload period (connecting to the portal and uploading all logged values):
15 minutes
Only the Portal administrator may provide you with other than default Logging / Data
update period settings (setup per each device).
2.3.3. SafeRange –range of allowed values
Safe Range is configured in the portal independently for each sensor. Whenever the
measured value strays outside this range, a message to the portal gets sent (even out
of the Data Upload period - default 15 minutes).

IoT monitoring 6 SD devices
2.3.4. Hysteresis/Idle range (sensor value)
The Hysteresis setting defines a tolerance range for suppressing alarm alerts. The
function prevents multiple alarm alerts (too many emails or SMS from the portal) if the
reading oscillates around the specified threshold. Hysteresis is configured
independently for each sensor.
The figure demonstrates two cases. Without the hysteresis idle range of 5 °C, the alarm
raised in point 8 would end in point 9; however, the hysteresis function keeps the alarm
active until the temperature reaches the upper limit of the tolerance band (point 10):
5 °C + (–15 °C) = –10 °C.
▪Hysteresis = 5 °C – The portal sends 4 Email (SMS) messages. Alert is sent
with beginning and end of Alarm State (points 4, 8, 10, 12)
▪No hysteresis (0 °C) – The portal sends 8 Email (SMS) messages. Alert is sent
with beginning and end of Alarm State (points 1, 2, 3, 8, 9, 12, 13, 14)
In determining when the Alarm ends, the Hysteresis value applies. The end of an Alarm
is only notified when the measured value is within the Safe Range and further under
the offset introduced by Hysteresis.
2.3.5. Safe Range vs. Notice Range
Each sensor has a set Safe Range. Faster communication to the portal when Safe Range
is exceeded can be useful for some cases.
Additionally, you can set up several Notices on the Portal which use their own,
independent Notice Range. These are used for setting up Actions. Using these, you can
set up multiple behaviors for different value ranges, like escalating alarms etc.

IoT monitoring 7 SD devices
2.3.6. Alarm Delay
You can set up a Delay value for each sensor. This means that if the measured value
steps out of the sensors defined Safe Range and a Delay is set up, the device (and the
user) won’t be notified of the sensors Alarm State until the Delay period ends.
This can be useful for example if you have an open door with a Door contact sensor
and don’t want to raise an alarm each time someone opens it, but only after it is left
open for 3 minutes.
Alarm status notification based on a Delay value:
▪Blue: Delay = 0
▪Yellow: Delay is non-zero

3. Setting up the device
3.1. Connecting the cables
1) Attach the external antenna
2) Connect the device to the Ethernet (with a patch cable to a switch, or a cross-
over cable to a PC)
3) Plug the power adapter into a power outlet and connect it to the power
connector. If you plugged the device into a PoE enabled switch or a PoE
injector, you can use the device without the power adapter
4) The Power Mode (green) LED in the RJ45 connector lights up
5) If the Ethernet connection works properly, the LINK (amber) LED lights up
after a short while and then flashes whenever any data transfer takes place
(activity indication)
6) Rapidly flashing LINK (amber) LED indicates communication with the DHCP
server
3.2. Configuring the IP address –HWg Config
3.2.1. Open HWg Config and find available devices
The tool is available for download at www.HW-group.com -> Software -> HWg Config
Double-click the icon to run HWg-Config. The program automatically searches for
connected devices. You can also start a search manually by clicking the Find Devices
icon.
The program searches for all available HWg devices in your local network.

3.2.2. Configure the network parameters
Click a MAC address (or double-click somewhere in the row) to open a basic device
configuration dialog:
•Enable DHCP (this will have the rest of the seetings get configured automatically
by your router)
•IP address / HTTP port (80 by default)
•Network mask
•Gateway IP address for your network
•Device name (optional)
Click Apply Changes to save the settings.
3.2.3. Restoring factory defaults
You can restore factory default settings in 3 ways:
Using HWg-Config
Right-click the device MAC address. Within 60 seconds of powering up the unit, factory
defaults can be restored using HWg-Config by selecting Load default values.
Using the Reset button:
1. Turn the device off
2. Press and hold the Reset button
3. Turn the device on and hold the button for another 5 seconds
4. All LEDs light up in sequence
5. Release button, device restarts with restored factory defaults
WWW interface of the device
1. Enter the device IP address in a web browser or click the underlined IP address
shown in HWg-Config.
2. Go to the System tab
3. Click Factory reset

3.3. WWW interface
All SD devices have the same graphical WWW interface. They only differ in the logo
and the I/O information.

•Calibrated Value –shows the value that comes from the Internal Value being
modified by the Calibration Table
•Unit –you can input the name of the unit you want displayed with the Calibrated

•Exponent –changes the placement of the decimal point for the Calibrated Value
•Calibration Table –many sensors use the voltage Internal Value to measure a
different value/unit. This table serves to mate Voltage readouts with their
corresponding values for the unit the sensor is designed to measure.

IoT monitoring 12 SD devices
For example a temperature sensor measures from 0° C to 100° C – the minimal internal
value of a 4-20 mA sensor is 4 mA and the maximum is 20 mA. For this example, you
would put 4 in the FROM column and 0 in the TO column (and °C in the Unit row above).
In the next row, you would put 20 in the FROM column and 100 in the TO column.
