Communication gateway iHUB-L1
Description of the device
The iHUB-L1 communication gateway is intended to connect various equipment into
communication network via Wi-Fi communication. The gateway has build-in two optical (IR)
communication ports and the RS485 serial communication with the MODBUS protocol. RS485
communication enables data transmission and thus connection of communication gateway into
the RS485 network and communication with various equipment, which is equipped with RS485
communication (e.g. energy meters, bi-stable switches, power monitoring devices, etc.), via TCP
MODBUS.
The iHUB-L1-IO is also equipped with pulse input and temperature sensor (Pt1000) input.

A built-in green LED diode indicates different operation states of the iHUB-L1. A tactile switch is
built-in for reset and factory reset of a gateway. Short press resets the gateway, pressing button
for more than 5 seconds (LED diode starts blinking fast) will do a factory reset (meaning setting
iHUB-L1 to factory settings and turn into access point mode). Connecting terminals are built to
be fastened according to EN 60715 standard. The iHUB-L1 interface with corresponding
equipment enables setting and reading the instruments.

Mounting
The iHUB-L1 is intended only for DIN-rail mounting. It should be mounted on a DIN-rail between
an energy meter and latching switch.
WARNING
Case is sealed. Do not open the device. No warranty if case is opened.

WARNING
Installation must be carried out and inspected by a specialist or under his supervision.
Wrong or incomplete connection of voltage or other terminals can cause non-operation
or damage to the device.
The iHUB-L1 should be connected to power supply voltage. Two IR communication ports are
assembled into the gateway, one on each side. The left one communicates with energy meter,
the right one is meant to connect to latching switch. The latching switch can be turned on/off
by energy meter with set limit values or by user via Wi-Fi network using dedicated software (e.g.
MiQen software).
Figure 5: IR and RS485 connection of iHUB-L1
Additionally, two devices (e.g. energy meters, bistable switches, power monitoring devices, etc.)
can be connected to the gateway via RS485 communication.
Up to 2 devices can be connected to the RS485 network allowing the iHUB-L1 to manage 4
devices altogether (1 energy meter and 1 latching switch via IR MODBUS communication,
additionally managing 2 devices via RS485 communication).
PLEASE NOTE
For proper operation of the IR communication, avoid a powerful external source of
light.

Communication connection
The complete iHUB-L1 system is assembled with three main units and two optionally units,
which are used for communication with outside world:
The power supply unit.
iHUB-L1 is supplied from AC power mains with nominal voltage 230 V. An isolated SMPS
power supply is used to supply main MCU as well as Wi-Fi module, communication units
and MCU peripherals.
The processing unit (MCU) with IR communication, RS485 communication, LED
indicator and Switch for reset/factory reset.
IR communication unit and RS485 unit are connected to MCU via UART interface. Various
equipment can be connected to iHUB-L1 communication gateway via IR communication or
via RS485 communication. Both IR communication modules using MODBUS protocol.
Wi-Fi module.
Wi-Fi module is equipped on each gateway and enables connection of iHUB-L1 to user's
Wi-Fi network using TCP MODBUS protocol. Furthermore, Wi-Fi module communicates
with main processing unit via UART interface.
Extension modules of iHUB-L1-IO (pulse input and temperature sensor (Pt1000)
input)
iHUB-L1-IO does not have any adjustable elements (e.g. potentiometers), which assures a
better long-term stability.

Introduction
Connecting iHUB-L1 is very transparent and user friendly. The flowchart below illustrates the
first few steps to more clearly understanding software settings.
Figure 6: Process flowchart
Connecting iHUB-L1 to Wi-Fi Network
After we mounted iHUB-L1 on a DIN-rail and supplied it with AC power (power-up the device),
we must connect iHUB-L1 to Wi-Fi network. At first, iHUB-L1 tries to connect to last successfully
added Wi-Fi network. If iHUB-L1 cannot connect to Wi-Fi in 60 seconds, it will start configuration
procedure. This mode is active for 3 minutes and after that, it cycles to connection mode again.

SETUP iHUB-L1 IN CONFIGURATION MODE
Search Wi-Fi networks with
your smartphone. Find Wi-Fi
network starting with IHL.
Figure 7: Selection of the
IHL Wi-Fi network
Some smartphones get pop-up
Sign to Wi-Fi network.
Figure 8: Pop-up sign
After connecting to IHL
network, configuration page
will appear.
If you do not get this page, you
can start a web browser on your
phone and go to IP address:
192.168.4.1.
Click on Configure Wi-Fi to get
available Wi-Fi
networks.

Select Wi-Fi network then enter
the password and click on save.
If you have hidden Wi-Fi network, you can
manually enter SSID and password. Click
on save and wait.
PLEASE NOTE
iHUB-L1 will now enter connection
mode and connect to the selected Wi-
Fi network. You can switch your phone
back to your previous Wi-Fi network.
Figure 10: Sign in to network
iHUB-L1 IP address
If the previous step is completed, iHUB-L1 will connect to Wi-Fi network. In order to connect to
iHUB-L1, you must find its IP address. There are several ways to find it:
1. MiQen configuration SW (Browse Ethernet devices)
2. Adroid Fling application
3. Windows file explorer
4. Apple bonjour service
Find IP address with MiQen
MiQen software is a tool for complete programming and monitoring of ISKRA measuring
instruments. Remote operation is possible by means of serial (RS485/RS232), USB or TCP/IP
communication. A user-friendly interface consists of six segments (Connection, Settings,
Measurements, Analysis, My devices, and Upgrades). These segments are easily accessed by
means of six icons on the left side.
The latest version of MiQen software can be downloaded from ISKRA d.d. website
https://www.iskra.eu/.

Communication gateway iHUB-L1
PLEASE NOTE
MiQen has a very intuitive help system. All functions and settings are described in Info
window on the bottom of MiQen window. In MiQen Help file, detailed instructions
about software usage, connection, and communication with a different type of devices,
driver installation, etc. are described.
MiQen has a functionality to search for network devices. Your PC must be connected to the
same network as iHUB-L1! All settings can be programmed using MiQen software.
Figure 11: MiQen programming and monitoring software
Start MiQen application and click on Browse ethernet devices.
Figure 12: Browse ethernet devices selection
MiQen scans Wi-Fi network and displays results. You get a list of all detected devices on your
network. You can double click on your device and MiQen will establish a connection with it.
