2.2.2 Server Address
Add a server to receive data being sent from the device. This can be
configured in the configuration tool shown below or via SMS command
shown above.
Note! The values sent by the devices will be in raw format.
2.2.3 Check for Firmware (FW) Updates
Device will connect to the internet to check if the firmware is up to date.
2.2.4 Restart Device
Restart the device without using buttons.

2.3 Settings & test
2.3.1 Select APN & Select User/Password
Select which APN to use. APN can be added using the configuration tool
shown below, or via SMS command shown above. The same principle goes
for User and password.
2.3.2 Logging
Log interval is where you activate automatic continuous logging of the signal
measurements. This is also where you specify the interval between logs.
Send interval determines how often the logged data gets transmitted to a
server. The server address can be setup via configuration tool or SMS
command.

3. Scanning
3.1 Scanning a signal
Step 1: Select Radio Bands
Broaden or narrow down your network scanning to only the bands you wish
to scan.
Note! Before selecting radio bands, please check what bands are
available in your country/used by your SIM-card provider. Searching
for inactive bands lead to negative results.
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.
RSRP - Reference Signal Received Power (the signal strength without noise
and interference)
measured in decibel meter (dBm). The signal is visualized in the signal bar
below the data.
RSRQ Reference Signal Received Quality (how well the signal is coded)
measured in decibel (dB). The signal
is visualized in the signal bar below the data.
In the bottom shows rolling information about PLMN & Band, Operator,
RSSI, Status (abbreviations explained under appendix).

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)
4.1 Communication Test
Ping to test network communication. Standard is set to Google’s server. This
can be change using the configuration tool shown below.
4.2 Upload Signal (Remote)
Uploading a signal is made through pushing “Send Data to Server” (See 2.2
Menu flowchart). Make sure you have IP + Port setup. You can easily add
this by sending a SMS command seen above in 2.1 SMS Commands.
Uploading signals continuously without pushing can be done through
activating logging and sending under settings.

4.3 Download Signal (Local)
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.
4.4 Current Network Data

5. 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, press “Set COM Port” to choose the right COM
port (see device manager, COM Ports. If no COM port shows up, make
sure the drivers got properly installed to your computer when the 770-
Pro was pluggeg in. 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. Above, the config tool says CT09.80 in the
name, but the terminal window shows the device having FW to match
CT09.50.

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 devices, press “File” in the
top left corner, then “save” in the dropdown menu and save the file to an
optional location. Make sure it’s saved as a .ctx file.
