1 Introduction
1.1 Product Overview
The mobile coumminucation router TAINY IQ-LTE is designed for industrial use and offers a
diversity of features and functionalities This manual provides security instructions and describes the
installation and operation of TAINY IQ-LTE.
Device
TAINY IQ-LTE
Data
2G / 3G / 4G
2 x Ethernet LAN/WAN
power supply 24 V DC
Wireless WAN
Connectivity
The TAINY IQ-LTE provides a wireless connection to the internet or to a
private network.
The TAINY IQ-LTE provides this connection anywhere a UMTS network
(Universal Mobile Telecommunication System = 3rd generation mobile
communications network), a LTE network (Long Term Evolution = 4th
generation mobile communications network) or a GSM network (Global
System for Mobile Communication = mobile communications network)
which provides IP-based data service is available. For UMTS, this means
the HSDPA data service (High-Speed Downlink Packet Access), the
HSUPA data service (High-Speed Uplink Packet Access), or the UMTS
Data Service. For GSM, this means EGPRS (Enhanced General Packet
Radio Service = EDGE) or GPRS (General Packet Radio Service).
For HSDPA and HSUPA the term HSPA+ is used in this manual.

Introduction
Page 6 of 147 TAINY iQ
Wired WAN
Connectivity
The TAINY IQ-LTE can also establish WAN connection via Ethernet lines
provided it is connected to a router with WAN access or a DSL modem.
The TAINY IQ-LTE connects via up to 2 Ethernet ports locally connected
applications or entire networks to the internet. Therefore it uses wireless
or wired IP connections. Direct connection can also be made to an
intranet which the external remote stations are connected to.
It can establish also a VPN (Virtual Private Network) between a locally
connected application/network and an external network using a wireless
or wired IP connection and can protect this connection from third party
access using IPsec (Internet Protocol Security).
Dual SIM
Being equipped with two SIM card slots, the TAINY IQ-LTE enables
alternative operation with a second SIM card, i.e. with a second operator,
which takes over the communication if a connection over the first SIM
card should be interrupted.

network contains at least one local application.
Local interfaces
ETH 0, ETH 1
(10/100-Base-T)
Interfaces of the TAINY IQ-LTE for connection of the local network. The
interfaces are marked on the device as ETH 0 to ETH 1 (10/100 Base-T).
The Ethernet interfaces have data transfer rates of 10 MBits or 100 MBits
(auto-sensing function MDI / MDIX). You can use ETH0 and ETH1 as
separate LAN network interfaces, or ETH0 as a wired WAN connection
(see chapter 6.5). Between the network on ETH0 (for instance
192.168.2.1) and ETH1 (for instance 192.168.1.1) is internally routed.
Local application
Local applications are network components of the local network, for
example a programmable controller, a machine with an Ethernet interface
for remote monitoring, or a notebook or desktop PC or the Admin PC.
Admin PC
Computer with Web browser (e.g. Windows Internet Explorer version 11
or later or Mozilla Firefox version 37 or Chrome from version 64 or later)
connected to the local network or the external network; used to configure
the TAINY IQ-LTE. The Web browser must support HTTPS.

External Power
Supply
Warning
Risk of damaging the device due to false voltage
Use only power supplies that are conforming with the DIN EN
62368-1 Annex Q standard.
The output voltage of the supply must not exceed 60 V DC.
The output of the external power supply must be short circuit
proofed.
Warning
Risk of damaging the device due false battery connection
