3. SCANNING SIGNALS
*Use “1.2 Device Navigation” above for help if you need.
Step 1: Select Radio Bands
Broaden or narrow down your network scanning to only the bands you wish to scan
Step 2: Scan for available operators
This might take a few minutes. The device displays all operators it can find in your area together with a
network technology (e.g. 4G or M1)
Step 3: Scanning a signal
Explanation
•The device is connected to a 4G band. The band is 7 and the frequency is 2600 MHz.
•Reference Signal Received Power (the signal strength without noise and interference)
measured in dBm. The signal is visualized in the signal bar below the data.
•Reference Signal Received Quality (how well the signal is coded) measured in dB. The signal
is visualized in the signal bar below the data.
•In the bottom shows rolling information about PLMN & Band, Operator, RSSI, Status

Explanation
•Band 7 / 2600 Mhz
•Referenced Signal Received Power (RSRP) is -82 dBm with Min & Max values below
•Referenced Signal Received Quality (RSRQ) is -7dB with Min & Max values below
•Public Land Mobile Network (PLMN) is 240007: The channel is 2850
•Scanned Network (Operator)
Communication test
Ping to test network communication. Standard is set to Google’s server. This can be change using the
configuration tool shown below.
Upload Signal
1. Uploading a signal is made through pushing “Send Data to Server”. Make sure you have IP +
Port setup. You can easily add this by sending a SMS command seen above in “2.1 SMS
Commands”
2. Uploading signals continuously without pushing can be done through activating logging and
sending under settings.
Download Signal
If logging is turned on while sending is turned off, the logged scans will be stored on the device. They
can be downloaded using the configuration tool explained further down the manual

4. CONFIGURATION TOOL
•Another way of configuring your ETM770 is by using the configuration tool. Begin by
downloading the latest configuration tool located under Resources on
https://etmiot.com/. Proceed by connecting the unit to a computer with the provided
USB charging cable.
1. Start the configuration tool and connect the device to a PC running Windows
2. Go to the terminal tab, use “Set COM Port” to choose the right COM port (see device
manager →Ports (COM & LPT)) in Windows. When correct port is selected, set
baud rate to 115200.
3. Open the port by pressing “COM(X): CLOSED”
4. Click anywhere in the black terminal window until you see a flashing square. Proceed by
restarting the unit by either holding down arrow UP and DOWN for 5 seconds, or write
“ETESC” in the command window.
5. Make sure that the firmware matches the configuration tool version unlike the picture above
(Should be CT0980 on both positions, not like CT0950 in this case)
1. When done configuring the unit, press the red button “WRITE MEMORY” to upload the
configuration to the unit
2. To see what configuration is already on the unit, press “READ MEMORY” when having the
unit connected to the computer to read it onto the configuration tool.
3. To save your configuration to use for future units, press “File” in the top left corner, then
“save” in the dropdown menu, and save the file to an optional location. Your device is now
ready to be configured.
