There are two serial ports on the terminal block, one is RS485, the other is configurable to
RS485 (default) or RS232. Only when users choose to configure the other one to RS232 will
serial debugging be available. Yet RS232 is used for serial communication under normal
circumstances. To activate the debug mode, users can long press the debug button before
power application till output data is displayed on the PC.
If users choose to configure both serial ports to RS485, serial debugging is not available.
Under such circumstances, debugging over Ethernet is an option.

GETTING STARTED

Vantron | Embedded in your success, Embedded in your better life
World-leading provider of embedded/IoT products and solutions
Vantron | G202 User Manual 14 www.vantrontech.com
2.1 Setting up the Gateway
Before you proceed with configuration of the Gateway, follow the steps below to finish
hardware connection.
1. Use the mounting bracket and screws provided to install the Gateway to a secure place.
2. Insert an activated SIM card, if any, into the SIM slot with the gold-colored contacts
facing down.
3. Push the SIM card to secure it.
4. Install the antennas to the antenna connectors and tighten the connectors.
5. Connect one end of an Ethernet cable to the WAN port of the Gateway and the other to
a live Ethernet port.
6. Connect one end of an Ethernet cable to the LAN port of the Gateway and the other to
your PC. (Skip steps 5 & 6 if you choose wireless network connection)
SIM

Vantron | Embedded in your success, Embedded in your better life
World-leading provider of embedded/IoT products and solutions
Vantron | G202 User Manual 15 www.vantrontech.com
7. Connect the female connector plug of the power cable to the terminal block of the
Gateway and the round end to the adapter.
8. Plug the adapter to a DC power outlet that provides voltage ranging from 9V to 36V to
turn on the Gateway.
The antenna connectors might vary with the functions. Should you have any trouble
installing the antennas, please contact the sales representative for solution.
Customers have the option for 4G LTE module that is AT&T and Verizon pre-certified.
Before you use a SIM card to provide wireless network access for the Gateway, make
sure the SIM card is activated with data plans (refer to 3.5.3 4G/LTE for the application
of the SIM card from the carriers if the module is pre-certified).
2.2 Gateway Login
The Gateway is designed to allow network connectivity with minimal configuration. That
said, you can configure the network settings and customize the Gateway from VantronOS
interface.
1. Input the default web login address of VantronOS in your browser: http://172.18.1.1/.
°Default user name: admin
°Default password: admin

Vantron | Embedded in your success, Embedded in your better life
World-leading provider of embedded/IoT products and solutions
Vantron | G202 User Manual 16 www.vantrontech.com
2. You’ll be directed to the web interface of VantronOS, and you can make configurations
and changes here with VantronOS interface.
3. For SSH login, use the IP address: 172.18.1.1 (default).
°Port: 22
°Account: root
°Password: rootpassword
The web login address coincides with the IP address of the Gateway, so you might have
to change the login address when you reset the IP address of the Gateway.
The latest version of Google Chrome or Firefox is recommended.
2.3 Connection to Vantron Gateway Management Platform
With Vantron gateway management platform, a console where multiple gateways could be
managed in groups to provide required information of a target workplace, the Gateway can
be monitored and managed remotely.
Refer to 3.6.4 DMP Agent for the configuration. More detailed information is available in
the user manual of Vantron gateway management platform.
2.4 Network Connectivity
When the Gateway has both wired and wireless connections, the status page will display
like below.
