1. Introduction
1.1 Overview
The TG453 is a compact 5G NR IoT gateway designed for IoT, M2M, and eMBB
applications requiring higher speed, lower latency data transmission, and capacity of
basic edge computing. It provides OpenWRT based Linux OS embedded environment
that allows developers and engineers to program and install their own application based
on Python, C/C++ to the hardware themselves.
The TG453 gateway has 5-Gigabit ethernet ports, 1-RS232, 2-RS485 to connect to
diverse field equipment and sensors, transferring the data to the cloud server via 5G/4G
LTE cellular network. It comes with industrial protocols, such as MQTT, Modbus
RTU/TCP, JSON, TCP/UDP and VPN to provide you an efficient and secure IoT data
connectivity between field devices and cloud server. The TG453 gateway has option of
dual sim/dual module for failover/load balance, providing robust and reliable wireless and
wired connectivity for your mission-critical industrial applications, such as EV charging
station, solar power, smart pole, smart cities, smart office, smart buildings, smart traffic
light, digital signage advertising, vending machines,ATM, etc.1.2Applications

2.2 Installation
2.2.1 Insert SIM/UIM Card
TG453 supports normal SIM/UIM only, so if you’re using a Micro SIM or Nano SIM card,
you will have to use a Micro SIM or Nano SIM to Normal SIM adapter, which normally
comes with your SIM card package.
Before you insert the SIM card, make sure your router is powered off, then use a needle
object(such as a pen) to push the button near the SIM tray(see page below), it will flick
out immediately. Put the SIM card to SIM tray with chipset upside, insert it to router and
make sure it’s tightly matched.
Image 3: SIM card and SIM tray installation
Warning: DON NOT install and swap SIM/UIM card when router is powered on.

If there have username and password, you need to choose authentication type.
Normally, just keep it as default.
⚫PAP, PlaintextAuthentication
⚫CHAP, Handshake authentication
You need to choose the authentication type according to Telco’s network, or you may fail
to dial up.
8) WAN Used As LAN
When you use 5G/4G/3G/2G cellular network to access internet, you can go to
“Advanced Settings” to change the WAN to act as a LAN port.
3.2.2 LAN
Menu of LAN are mainly for configuring IP address of router, enabling DHCP server, and
assign the IP address.
The meaning of the parameters are as follows.
1) IPv4 Address
To configure IP address of LAN port, default value is 192.168.1.1, which is also the login
IP address when you want to enter into the web config page, so you can change the IP
address of LAN yourself.
