Product description3
3.1 System description
KLAROconnect is used for communication between the wastewater treatment plant and the KLARO
WebMonitor. KLARO WebMonitor offers the possibility of remote monitoring, remote maintenance
and remote control of the wastewater treatment plant from a distance using a smartphone or computer
via the internet. You can find more information about this at https://klaro-webmonitor.de/ . Via KLARO-
connect, all operation-relevant data such as settings, events and operating hour meter readings of the
KLAROcontrol.S and KLAROcontrol. M are transmitted to the KLARO WebMonitor.
KLAROconnect combines a 4G module and a LAN adapter. The enclosed antenna covers the fre-
quency ranges 790 - 960 MHz, 1710 - 2170 MHz, 2570 - 2620 MHz. You will find more detailed infor-
mation in the appendix to these operating instructions.
KLAROconnect is specifically optimised for M2M and IoT applications, delivering maximum data rates
of up to 10 Mbps downlink and 5 Mbps uplink. KLAROconnect (SIM) is backward compatible with ex-
isting EDGE and GSM/GPRS networks, ensuring that it can connect in remote areas without 4G or 3G
coverage.
The power connection is made directly to the control unit via the data cable included in the scope of
delivery (art. no.: 982223). In the event of a power failure, KLAROconnect no longer works. Data
transmission between KLAROconnect and the control is also carried out via the data cable.
The status of KLAROconnect is displayed via control LEDs.
A Velcro strap is supplied as standard for attachment.

3.3 Mounting KLAROconnect
3.3.1 Velcro fastening
The Velcro tape included with the KLAROconnect is used
to mount the communication module.
Note: The glued areas must be made dust-free before
applying the Velcro tape.
3.3.2 Mounting adapter (available from WAGO)
The KLAROconnect can be mounted on a DIN 35 rail using two mounting feet (WAGO 209-123). To
do this, the mounting feet are mounted with the screws on the underside in the holes provided.

Commissioning4
In the LAN adapter operating mode, the chapters 4.1 and 4.2 can be skipped.
4.1 Antenna
The antenna must be connected to the antenna socket of the KLAROconnect by means of a screw
connection. The antenna must be positioned in such a way that reliable reception is possible. You can
check the reception quality on site by trying out the SIM card in a mobile phone or smartphone before-
hand.
4.2 Mini SIM card
For operation as a 4G module (modem), a valid mini SIM card must be present in the KLAROconnect:
•Mini SIM card format
•Recommended data volume per month >500MB
•The SIM card must be able to transmit M2M
•Deactivate the PIN (to do this, -insert the SIM card -into a mobile phone and deactivate the
PIN request under the menu item "Security").
When the KLAROconnect is switched off (the LEDs are off), insert the SIM card into the device (see
also chapter 5.3.1).
4.3 Switch on KLAROconnect
After the card has been inserted, KLAROconnect can be connected to the power supply (switch on
KLAROcontrol).
The connection with KLAROcontrol is fully automatic. A WEB symbol appears in the KLAROcontrol
display . KLAROconnect needs up to 8 minutes to start up completely.
After successful authentication, LED6 flashes with interval 100ms on, 100ms off, 100ms on, 700ms
off. If a SIM card is used, LED5 flashes with an interval of 1800ms on, 200ms off. The KLAROconnect
is now ready for communication.
If there is no signal changeover, this can have several causes:
Operating mode LAN connection
1. No internet
2. Firewall upstream
3. Missing or incorrect configuration of the KLAROconnect
4. Faulty contacting of the plug connections
Operating mode SIM connection
1. SIM card is not released
2. No mobile phone reception
3. Missing or incorrect configuration of the KLAROconnect
4. Faulty contacting of the plug connections
4.4 Control configuration
No settings need to be made in the control unit.
4.5 Create attachment in WebMonitor
After a successful connection has been established, the system can be created in the WebMonitor.

Removing and inserting the SIM card during operation requires initialisation of the KLAROconnect
software. Therefore, the KLAROconnect must be restarted after reinserting the SIM card. To do this, it
is only necessary to de-energise KLAROconnect for approx. 5 seconds.
No liability is accepted for the loss of data due to the removal of the SIM card dur-
ing operation. No liability is assumed for the correct initialisation of the KLARO-
connect after reinserting a SIM card that was removed during operation.

Connecting the KLAROconnect to a computer6
To connect the KLAROconnect to a computer, a router and an Ethernet cable are required.
1. Connect KLAROconnect (X6) and KLAROcontrol (X10) with a data cable (art.no.: 982223).
2. Connect KLAROconnect and computer to the router (LAN interface) using an Ethernet cable
(RJ45).
3. Insert the SIM card into KLAROconnect. Unlock the PIN of the SIM card beforehand, e.g. by
mobile phone or smartphone.
4. Establish power supply.
6.1 KLAROconnect Configuration
Entering http://klaro.local in the address bar of the Internet browser calls up the KLAROconnect menu.
KLAROconnect menu can also be called up alternatively via the assigned IP in the DHCP server of
the router.
6.2 SIM profile configuration
•A SIM card profile with details of the APN of the provider can be created via the graphical user
interface (GUI).
•If the profile does not appear in the list after the new creation, reload the page with the F5 key.
•A profile can be connected, disconnected and deleted.
•With the autoconnect option, the created profile is automatically used to establish the connec-
tion when starting.
•The fastest available mobile radio standard is automatically used.
The APN depends on the provider of the SIM card and the purpose of use. APN is required for Ma-
chine to Machine (M2M) use.

6.3 Websocket URI
•Websocket client URI to connect to the WebMonitor can be set via the graphical user inter-
face:
Server Germany: ws://188.174.236.242:4000
Server France: ws://193.248.238.194:4000
Server Australia: ws://119.225.139.2:4000
•Websocket URI can be changed via the graphical user interface and is directly active.
•KLAROconnect forwards the defined messages (JSON) from the WebMonitor server to the
KLAROcontrol (if the connection is established).
•Responses from the KLAROcontrol are passed on to the WebMonitor via the KLAROconnect
using the websocket (ws://).
6.3.1 Websocket URI Configuration Guide
1. Call up the KLAROconnect menu via the graphical user interface.
2. Select the menu item "WebMonitor
3. Enter the URI, e.g. for the use of the KLARO WebMonitor Germany
ws://188.174.236.242:4000, into the websocket field and save it with the "Save" button.
4. Confirm the following message with OK.
5. If no further configuration is required, the internet browser can be closed. Logging off is not
necessary. In the further course, disconnect KLAROconnect and KLAROcontrol from the
power supply. In the next step, carry out the commissioning (chapter 4).

Software update via micro SD card7
The software update for KLAROconnect can be made using a micro SD card with an image.
1. Flash the KLAROconnect image onto a micro SD card of at least 4GB using balenaEtcher.
2. Disconnect KLAROconnect and KLAROcontrol from the power supply.
3. Insert the micro SD card into KLAROconnect (see chapter 5.3.1).
4. Connect KLAROconnect to the KLAROcontrol and to the power supply.
5. Firmware is automatically installed from the micro SD card. (The process takes approx. 7 to
10 minutes).
6. After the process is completed, KLAROconnect switches off automatically. (Green power LED
goes off).
7. Disconnect KLAROconnect and the KLAROcontrol from the power supply.
8. Remove the micro SD card.
9. Connect KLAROconnect to the KLAROcontrol and to the power supply.
10. KLAROconnect starts (web interface accessible via LAN on http://klaro.local).
11. Check SIM card configuration and re-create if necessary (chapter 7.3).
12. The arrows in the web symbol in the KLAROcontrol flash at intervals of approx. 10 se-
conds after the connection is established.
