1.5 Serial Port Introduction
There are two serial ports on the green terminal block of the Gateway, one is RS485 (COM1)
and the other is configurable to RS485 or RS232 (configured before shipment).
COM2 is used for serial communication by default. To activate the debug mode (settings:
57600 8N1), users can long press the debug button before power application and release
util there is output data on the host PC. When the Gateway is powered off, the port will
restore to the communication mode. However, it is recommended that COM2 is not used
for serial debugging when it is configured to RS485 due to the likeliness of garbled data
and the need of an RS232 to RS485 adapter.

GETTING STARTED

Vantron | Embedded in your success, Embedded in your better life
World-leading provider of embedded/IoT products and solutions
G202 Edge Computing Gateway | 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 into SMI1 slot with the gold-colored contacts facing down,
or, insert into SIM2 slot with the gold-colored contacts facing up, or, insert two activated
SIM cards to the slots, respectively;
3. Push the SIM card to secure it;
4. Insert a Micro SD card into the Micro SD slot with the gold-colored pins facing up;
5. Install the rubber stick antennas to the WLAN antenna connectors and the sucker
antennas to the LTE antenna connectors;

Vantron | Embedded in your success, Embedded in your better life
World-leading provider of embedded/IoT products and solutions
G202 Edge Computing Gateway | User Manual 15 www.vantrontech.com
6. Connect one end of an Ethernet cable to the WAN port of the Gateway and the other to
a live Ethernet port;
7. Connect one end of an Ethernet cable to the LAN port of the Gateway and the other to
your PC;
Skip steps 6 & 7 if you choose wireless network connection.
8. Connect the terminal end of the DC power connector to the power terminal of the
Gateway and the round end to the adapter;
9. Plug the adapter to a DC power outlet that meets the supply voltage requirement (9V
to 36V) to turn on the Gateway;
10. The power indicator will turn solid green upon power application.
The antennas might be different from what used for illustration here. Should you have
any trouble installing the antennas, please contact the sales executive 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 /Super user: root
°Default password: admin / Super user password: rootpassword
2. You’ll be directed to the web interface of VantronOS, and you can configure and change
the settings of the Gateway here.
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 LAN port IP address of the Gateway, so you
might have to change the login address when you reset the IP address.
Refer to SSH Access included in 3.10.3 for more details.
The latest version of Google Chrome or Firefox is recommended.
