1. Product Overview
1.1 Product Introduction
Industrial router ICR-2701 is LAN Router &Edge Computing Gateway focused on the
global market.
The router, which may have a metal or plastic box, is equipped with two independently
configurable Ethernet ports, with one USB 2.0 host interface and with 5 LEDs for status
indication.
The router supports VPN tunnel creation using various protocols to ensure safe commu-
nications. The router provides diagnostic functions which include automatic monitoring of the
wireless and wired connections, automatic restart in case of connection losses, and a hard-
ware watchdog that monitors the router status.
With open Linux platform and wide possibilities of programming customer SW applications
in Python,C/C++. The Advantech existing app library Router Apps (formerly User modules)
with apps already developed to enhance specific router functionality including industrial pro-
tocol conversions and support of IoT platforms such as MS Azure,Cumulocity,ThingWorx,
and others are supported on the router.

1.6 Mounting Recommendations
The router can be placed:
•on a flat surface,
•on a DIN rail EN 60715 with the metal DIN rail clip (see Chapter 1.7)
For most applications with a built-in router within a switchboard, it is possible to recognize
two kinds of environments:
•A non-public, industry environment of low voltage with high interference,
•a public environment of low voltage and without high interference.
For both of these environments, it is possible to mount the router to a switchboard, af-
ter which there is no need to have examination immunity or issues in connection with EMC
according to EN 61439-1:2011.
In compliance with the EN 61439-1:2011 specification, it is necessary to observe the
following assembly instructions for a router attached to a switchboard:
•For whip antennas it is recommended to observe a minimum distance of 6 cm from ca-
bles and metal surfaces on every side in order to avoid interference. When using an
external antenna separate from the switchboard it is necessary to fit a lightning conduc-
tor.
•When mounting a router on sheet-steel we recommend using a cable antenna.
•For all cables, we recommend to bind the bunch, and for this we recommend:
–The length of the bunch (the combination of power supply and data cables) should
be a maximum 1.5 m. If the length of data cables exceeds 1.5 m or if the cable is
leading towards the switchboard, we recommend installing surge protectors.
–Data cables must not have a reticular tension of ∼230 V/50 Hz or ∼120 V/60 Hz.
•Sufficient space must be left between each connector for the handling of cables,
•To ensure the correct functioning of the router we recommend the use of an earth-
bonding distribution frame for the grounding of the grounding screew, see Chapter 2.2.

1.7 DIN Rail Mounting
The DIN rail clip is suitable for a DIN rail according to EN 60715 standard only. There are
four possible positions of the clip as shown in Figure 5.
The DIN rail clip is the same for the metal and plastic router box. It just differs by the crews
used.
When mounting the DIN rail clip, tighten the screws with max. torque of 0.4 Nm.
Figure 5: Position of the DIN Rail Clip
To remove the router from the DIN rail it is necessary to lightly push down the router so
that the bottom part of the DIN rail clip hitched to the DIN rail get out of this rail and then fold
out the bottom part of the router away from the DIN rail, see Figure 6.

2. Hardware Functionality
See Chapter 1.2 for the product hardware overwiew. Table 1lists a short description of the
hardware, including the links to the chapters with a detailed description.
2.1 Ethernet Interfaces
The panel socket of RJ45 is used for Ethernet interface. The pinout of the socket is shown
in Figure 1and described in Table 3.

2.2 Power Supply
The pins of power supply are physically connected to the 6-pin terminal block panel socket
located on the left panel. The connection of power supply is shown in Figure 2and described
in Table 4.
Figure 2: Connection of Power Supply
Pin Signal mark Description
1PWR(+) Positive pole of DC supply voltage (+9 to +48 V DC)
2PWR(-) Negative pole of DC supply voltage
Table 4: Power Supply Pinout
Required power supply voltage for the router is between +9 V and +48 V DC, see the
connection scheme on Figure 2. Protection against reversed polarity without signaling is built
into the router. For correct operation it is necessary that the power source is able to supply
a peak current of 1 A.
Unit has to be supplied by a power supply specified as a Limited Power Source (LPS) or
CEC/NEC Class 2 source of supply.
All metal parts of the router in a metal box, including the box itself, are connected with
the negative pole of the power supply (common pole). If recommended for the installation
environment, protect the router by grounding it properly by the grounding screw on the right
panel, see Figure 3.

2.3 USB Port
There is one USB 2.0 host port with socket of USB-A type. USB Mass Storages and FTDI
serial converters are supported. For a piece of advice, how to fix an unsupported FTDI chip,
see the Commands and Scripts application note, chapter How to Use Unsupported FTDI Chip.
The USB port is disabled on overload to prevent its damage (connected device is trying to get
too high current). The port is enabled again after the reboot of the router.
Mounting USB Flash Drive to the System
It is necessary to mount the USB flash drive to be able to access it in the system of the
router. Follow these steps to mount the drive:
•Use the dmesg command to see the list of recently connected devices.
•In the output of the command find out the entry for the microSD card, for example:
sda: sda1
•To mount the card to to mnt directory, use the mount command:
mount /dev/sda1 /mnt
For more information about the commands for creating, mounting, checking and unmounting
a file system on a USB Flash Drive, see the application note for Ext4_tools router app.
USB Socket Pinouts
USB socket pinouts is described in Figure 4and Table 5.
Figure 4: USB Connector Pinnout
Pin Signal mark Description Data flow direction
1+5 V Positive pole of 5 V DC supply voltage, 0.5 A
2USB data - USB data signal – negative pole Input/Output
3USB data + USB data signal – positive pole Input/Output
4GND Negative pole of DC supply voltage
