1 QUICK START GUIDE
Generally, we send devices pre-configured. If your devices are pre-configured by us, please go through
the user-friendly procedure to get started with your ER Beam system, which takes only a few minutes to
get the process rolling.
1 Power on Gateway and turn on its inbuilt Wi-Fi network.
2 Connect your Android phone to the ER Beam Wi-Fi network.
3 Connect the Android cable to the phone first using the OTG adapter.
4 Open the ER Beam Offline Android app.
5 Load the project and tap on it to go to the home screen of the app.
6 Then connect the Android cable's other end to the Node and click on Setup Device and follow the
wizard.
7 Repeat step 6 for all your Nodes.
8 Then press the Cloud Sync on the app to sync back all the Node settings to the gateway.
9 Now the Nodes will send the sensor data at the configured time intervals.
10 Optionally, the data can be exported and engineering conversions can be set using the Gateway
software.

2 SETTING UP WIRELESS ANALOG NODE
This section provides information on setting up an Analog Node to work with the offline ER Beam gateway.
2.1 Installation
The Nodes can be directly affixed to a flat surface using M6 screws. However, for more sophisticated
mounting scenarios, we recommend using the node bracket. The node bracket can be used to easily mount
the node on flat surfaces, on pipes using U-bolts or cable-ties, or in other complicated settings.
If you are using the bracket, first fix the node device to the bracket using M6 screws and nuts as shown
below.
For four channel devices (BEAM-AN-S4), use M4 screws to mount the nodes to flat surfaces or brackets.
Use four screws and nuts to attach the node to the bracket (Refer to figure 1).
Connect the SMA antenna to the bulkhead. Once the mounting is complete, the node should look as in
figure 2.

3 Switch off the Node and insert the battery while ensuring the correct polarity.
2.3 Configuring via the ER Beam Offline App
1 Obtain an Android phone and connect it to the ER_Beam Wi-Fi network. (See the Gateway section to
learn about switching on the ER_Beam Wi-Fi network.)
2 Connect the Android smartphone to the Node via an OTG adapter.
NOTE: Please make sure the Node is switch off before connecting to your Android phone.
3 Switch on the Node.
4 Open the ER Beam app on the phone.
NOTE: You need to add the Node and create the project first before you commission the tilt
meter. Please refer to ‘Gateway Setup’ section in the users’ manual for Gateway for
details.

(ii) Click on “Setup Device” on the menu (at the bottom of screen), the app will show connected node
information.
(iii) Optional Step: If Wireless Mesh (Relay) function is to be deployed, click on "Wireless Mesh" toggle
button to enable. Once
(iv) done, click on “Setup Sensor”, you can now configure the sensor settings

(v) After clicking ‘Setup Sensor’, sensor setup page will open with the available channels Tap the
“Arrow icon” on the respective channel which your sensor is connected to.
(vi) Sensor setting can be made as follows:
Sensor Code: Desired sensor name.
Sensor Type: Select respective sensor type.
Parameters: Turn on the parameters as connected to the Node.
Excitation time: Set the warm up time required for the sensor.
Excitation Voltage: Select either 5 or 12 or 24, depending on the sensor.

(vii) Click Save Settings. The Node will now read the configured sensor.
(viii) On next page, you will see the first reading.
(ix)To get another reading, click on the arrow icon. If the reading is ok, enable the sensor by switching
on the android icon (colour changing to blue).

(x) Repeat above steps to configure other sensors connected to the Node.
(xi) Once all sensors are configured, click on “Enable Sensor” button. It will take you to next page
“Scanning Network” which will scan the wireless signal strength (RSSI) between the Node and
Gateway.
(xii) After receiving the Network Test information, if you need to, you can perform another network test
by pressing the button located at the lower right corner.
