Requirements
• DEXGate2
• Power supply
• Wi Antenna
• 3G Antenna (only for DEXGate2-3G)
• A computer or tablet with wi
• Ethernet network cable
• Network conguration data
• SIM Card (only for DEXGate2-3G)
1. Connect the wireless antenna on the connector under the miniUSB port.
2. Connect DEXGate2 to the Internet. You have 2 options:
a. Ethernet: To connect the DEXGate 2 via Ethernet connect the Ethernet cable to DEX-
Gate2 and to the local network.
b. GPRS/3G (only DEXGate2-3G): To connect the DEXGate2 to 3G, connect the 3G anten-
na into the connector. Then, insert the SIM into the slot on the top of the datalogger.
It is recommended that you disable the PIN of the SIM card from a mobile phone before
inserting it into the DEXGate2.
3. Power on the DEXGate2 by connecting it through a Power Supply (7 to 50V DC).
1. Wait about 1 minute and connect your laptop, smartphone or tablet to the WiFi network
called DEXGATE_XXXXXXXXXXXX, where XXXXXXXXXXXX is the identier of the DEXGate2.
2. To access the network you must enter the password (the default password is the identier
of your DEXGate2 in capital letters)
3. Open your Internet browser, go to http://172.16.0.1 and enter the username and password
(default for both is “admin”).
4. Write down the device ID found on the menu “Status” at your DEXGate2 or at the sticker
on the device, which will be necessary to register the device in DEXCell Energy Manager (the
identier has the format 00D09 ...).
1. Ethernet: Go to System > Ethernet and Enable DHCP* or disable it and enter the congu-
ration data of the network provided by your network administrator.
(* In case of doubt, ask your system administrator).
2. GPRS/3G (only DEXGate2-3G): Go to System>GPRS/3G, enable the connection and enter
the relevant data regarding the operator of the SIM.
• It is recommended that you disable the PIN of the SIM card from a mobile phone be-
fore inserting it into the DEXGate2
1. DEXGate2 connection
2. Access the administration portal
3. Internet settings
1. Go to System > Time and date and select the timezone according to the location. Then just
click on Save. (DEXGate2 uses the UDP port 123 to synchronize the time*)
2. If Synchronization through UDP port 123 is not available, you can set the date and time
manually by selecting Manual (Not recommended).
(* In case of doubt, ask your system administrator).
NOTE: The DEXGate2 registration process in DEXCell Energy Manager can be done before or after
installing the device.
1. Access DEXCell Energy Manager with your username and go to Settings > Gateways
2. Click on “Register a new gateway” and select DEXGate2
3. Enter a name and the serial number or “identier” of DEXGate2 (lowercase letters) that
you will nd on the menu “Status” at your DEXGate2 or at the sticker on the device. Select a
time-zone and click on Save.
4. Enter at “Edit” and write down the “Gateway token” generated by DEXCell Energy Manager
at this screen. This code must be entered in the DEXGate2 at the end of the registration pro-
cess.
5. Through the web interface conguration access DEXGate2 Modbus> Settings. In Modbus
conguration you will nd the following lines where you have to add the “Gateway token” you
wrote down at the previous step:
# token of this dexgate in dexcell
token=xxxxxxxxxxxxxxxxxxxxxxxxxx
6. Click “Save and reboot”
4 . Set Date and Time
5 . Register DEXGate 2 in DEXCell Energy Manager
At this point, if you have internet access, you may already have remote access to your DEXGa-
te2 from DEXCell Energy Manager.
The DEXGate2 uses UDP port 1196 to connect to our VPN (remote.dexcell.com)*.
1. Go to Diagnostics > Remote Support and check whether the DEXGate2 is connected
to our VPN
2. If not, click Connect
(* In case of doubt, ask your system administrator).
Modbus conguration: Connect the meters to DEXGate2 using the supplied adapter (DB15
Terminal block).
Each meter works in a particular way, so we strongly recommend reading the meter user
manual.
The meter conguration can be done from the web management interface in DEXGate2.
To connect Modbus meters via RS485, you must use terminals A (+), B (-) and S (shield).
6. Remote access
7. Connect and congure the meters
Read the full manual for detailed information about installing the most common meters and
how to set the DEXGate2 to recognize them.
For modbus devices, indicate the BUS speed and the meters’ Modbus addresses from the
menu “Modbus conguration” at DEXGate2.
You must also specify the “Gateway token” (if you have not done so before).
