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 LEDs for status indication. The router can be
equipped with a dual-band WiFi module, but this must be part of the initial configuration – it cannot be
assembled to the router at some point in the future.
The router supports the Low Power Mode and hardware watchdog, which monitors the router status
and performs an automatic restart if required.
The router supports VPN tunnel creation using various protocols to ensure safe communications. The
router provides diagnostic functions which include automatic monitoring of the wireless and wired connec-
tions, automatic restart in case of connection losses, and a hardware 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 de-
veloped to enhance specific router functionality including industrial protocol conversions and support of IoT
platforms such as MS Azure,Cumulocity,ThingWorx, and others are supported on the router.
Examples of possible applications
• mobile office
• security system
• remote monitoring
• vending and dispatcher machines

1. Product Overview 1.7 Mounting Recommendations
1.7 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 1.8)
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, after 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 as-
sembly instructions for a router attached to a switchboard:
• For whip antennas it is recommended to observe a minimum distance of 6 cm from cables 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 conductor.
• 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 max-
imum 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 2.3.

1. Product Overview 1.8 DIN Rail Mounting
1.8 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 4.
The DIN rail clip is the same for the metal and plastic router box. It just differs by the screws used.
When mounting the DIN rail clip, tighten the screws with max. torque of 0.4 Nm.
Figure 4: 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 5.

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 Antennas
If the router is WiFi equipped, connect the WiFi antenna to the WiFi RP-SMA female connector on the
front panel.
Recommended tightening moment for screwing the WiFi antennas to the SMA female connectors is 0.9
Nm.
2.2 Ethernet Interfaces
The panel socket of RJ45 is used for Ethernet interface. The pinout of the socket is shown in Figure 7
and described in Table 5.

2. Hardware Functionality 2.3 Power Supply
2.3 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 8and described in Table 6.
Figure 8: Connection of Power Supply
Pin Signal mark Description
1 PWR(+) Positive pole of DC supply voltage (+9 to +48 V DC)
2 PWR(-) Negative pole of DC supply voltage
Table 6: Power Supply Pinout
Required power supply voltage for the router is between +9 V and +48 V DC, see the connection scheme
on Figure 8. 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, see Figure 9.

2. Hardware Functionality 2.4 Low Power Mode
2.4 Low Power Mode
In applications requiring low power consumption (such as solar power - not 7/24 mode) is strictly
recommended to use LPM mode prior to powering down the entire router.
LPM (Low Power Mode) is a router mode where the router is in sleep mode with minimal power con-
sumption; see Chapter 4.1 for the LPM consumption. The router can be woken up from this mode after a
predetermined period of time. Putting the router into LPM mode can be done using the lpm command, see
Commands and Scripts application note for more details.
2.5 USB Port
There is one USB 2.0 host port with a USB-A type socket. The router supports USB Mass Storages and
FTDI serial converters. For guidance on how to address an unsupported FTDI chip, refer to the Commands
and Scripts application note, specifically the chapter on How to Use Unsupported FTDI Chip.
The USB port is designed to disable on overload to prevent potential damage (occurs when a connected
device draws excessive current). The port is re-enabled after the router is rebooted.
Mounting USB Flash Drive to the System
To access a USB flash drive in the router’s system, it must be mounted. Follow these steps to mount the
drive:
• Use the dmesg command to view the list of recently connected devices.
• Identify the entry for the USB flash drive in the command’s output, for example:
sda: sda1
• To mount the drive to the 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, consult the application note for the Ext4_tools router app.
