Product Overview

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 connections, 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 developed 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.

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, 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 assembly 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 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 2.3.

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.

Warning: The DIN rail clip is the same for the metal and plastic router box. It just differs by the screws used.

Info: When mounting the DIN rail clip, tighten the screws with max. torque of 0.4 Nm.

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.

Product Label

• The figure below shows an example of the product labels with all the information printed on them.

Hardware Functionality

See Chapter 1.2 for the product hardware overwiew. Table 1 lists a short description of the hardware, including the links to the chapters with a detailed description.

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.

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 4.

Info: The isolation barrier of the Ethernet ports against the ground is 1500 V.

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 8 and described in Table 5.

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.

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 consumption; 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.

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.

USB Socket Pinouts

The USB socket pinouts are described in Figure 10 and Table 6.

LED Status Indication

There are LED indicators on the front panel of the router to provide router status information. Moreover, ETH connector, has two additional LEDs providing information about the port status.

Reset Functions

Before initiating a factory reset on the router, consider creating a backup of its configuration.

The RST button serves three different purposes:

• Reset: Hold the RST button for less than 4 seconds; the router will reboot, applying its customized configuration. You can also trigger the router reset by selecting the Reboot menu option in the router web GUI.
• Factory Reset: To restore the router to its default factory configuration, press and hold the RST button for more than 4 seconds. The PWR LED will turn off and then back on. It’s recommended to hold the RST button for an additional 1 second after the PWR LED comes on.
• Emergency Factory Reset: If the router fails to boot due to incorrect configuration, power off the router by disconnecting its power supply. Then, while holding the RST button, power on the router and continue holding the RST button for at least 10 seconds. This action will reset the router’s configuration to the default settings.

Use a narrow screwdriver or any small tool to press the RST button.

Accessories Connection

Before putting the router into operation, make sure to connect all the components required for running your applications. Refer to Chapter 1.2 for an overview of the hardware.

Router Configuration

You can perform the initial configuration of the router using a web browser on your PC. This interface allows for router monitoring, configuration, and administration. Begin by connecting the power supply to the router (refer to Chapter 2.3). The router will initiate its boot process. Ensure your PC is configured to obtain IP settings automatically from the network. Connect your PC’s network card to the default LAN interface of the router, Ethernet port ETH0. The DHCP server will assign an IP address to your PC.

To access the router’s web interface, enter the following address in your web browser: https://192.168.1.1. Please note that using the HTTPS protocol for secure communication over the network is mandatory. There is just the root user account created on the router by default. Check the product label on the router for the default password1 Access the web interface by logging in with the root user and the corresponding password. Successful login grants access to the router’s web interface. Consult the router Configuration Manual [1] for detailed descriptions and examples of router configuration.

Warning

• After logging on to the device for the first time, we strongly recommend changing the default password due to security reasons.
• For security reasons, we recommend regularly updating the router’s firmware to the latest version. Downgrading the firmware to an older version than the production version or uploading firmware intended for a different device may cause the device’s malfunction.
• All routers have the WebAccess/DMP client pre-installed by default. The activated client periodically uploads router identifiers and configuration to the WebAccess/DMP server. See the configuration manual [1], chapter Basic Information -> WebAccess/DMP Configuration, for more information.

Appendix A

Appendix A: Troubleshooting

Warning: If you cannot connect to the router from your PC, your network card may be configured in such a way that it is not possible to connect to the router. Take one or more of the following steps in order to solve the problem:

• Make sure your PC’s network card is configured to obtain the IP address form the DHCP server (by default the DHCP server is running in the router).
• Connect the router to the PC via Switch.
• Connect the router to the PC, start the router first and then start the PC after the router’s initialization.

Ethernet connection fails or is not establishing

• It is possible to turn auto negotiation off and set a rate and duplex manually on the Ethernet interface of the router. Available on “LAN Configuration” page in the router.

I cannot connect from the Internet to the device behind the router. I have NAT enabled

• The device’s gateway has to be configured so it points to the router.

I can’t access my Web server placed behind the router over NAT

• The remote HTTP access to the router has to be disabled on “NAT Configuration” page in the router. Also enable “Send all remaining incoming packets to default server” feature and fill in the IP address of your Web server. On the Web server, the default gateway has to be the IP address of the router.

DynDNS doesn’t work

• If the same IP address is recorded in your canonic name as a dynamically assigned address, it means that the provider is using NAT or a firewall.
• You can verify NAT using ping to your server with static address and then compare with router’s IP address.
• You can verify a Firewall by accessing remotely to the router’s Web interface.
• The operator may not provide the address of DNS server and without DNS server’s address it is impossible to connect to the dyndns.org server. The following messages will be shown in the System Log:
  • DynDNS daemon started
  • Error resolving hostname: no such file or directory
  • Connect to DynDNS server failed

L2TP or IPSec isn’t establishing

• Check the “System Log” page for error messages.

IPSec tunnel establishes but the communication does not run

• Probably there are bad routing rules defined in the connected devices, or the default gateway.

Serial communication is not working

• Verify that the router model supports serial communications. Also verify the serial communication settings. To do so, open the router’s configuration menu via the web browser, select the appropriate “Expansion Port” from “Configuration” part of the menu and verify the settings.

Is the router Cisco compatible? Can I use the Cisco configuration?

• No, the Firmware in the router (Conel OS) is based on Linux with BusyBox. Thus the Cisco configuration cannot be used. But network connections are defined by standards so connecting the router to the Cisco or other networking devices is possible and will be compatible.

FTP or SFTP does not work

• FTP will work on v2 routers only. You can use SFTP on all routers to transfer files to/from the router. If having troubles with FTP on v2 routers, make sure you have FTP enabled: “Configuration” section, “Services”, “FTP”. Then you can connect with any client on port 21 with name and password same as for the Web interface. If having troubles with SFTP, make sure you have SSH enabled: “Configuration” section, “Services”, “SSH”. Then you can connect with any client on port 22 with name and password same as for the Web interface.

How can I connect to the router’s command line? (SSH, Telnet)

• You can use SSH on all routers or Telnet on v2 routers only. SSH is enabled by default, but you can verify in Web interface in “Configuration” section, “Services”, “SSH”. Then connect with any SSH client on port 22 of the router. User and password is the same as for the Web interface. Telnet on v2 routers can be enabled here: “Configuration” section, “Services”, “Telnet”.
