ICR-2437
1. Product Overview
1.1 Product Introduction
Industrial cellular router ICR-2437 is designed for wireless communication in the mobile
networks that make use of traditional cellular technologies.
Industrial cellular router ICR-2437 is designed for wireless communication in LTE 450 MHz
networks as well as in standard 4G public European LTE networks. LTE 450 MHz brings
deeper LTE signal penetration than standard 4G public LTE frequencies and is ideal for Indus-
trial IoT and critical infrastructure applications.
The ICR-2437 offers a unique design supporting both LTE 450 MHz bands B31 and B72
in one single router unit. Router gateway construction provides state-of-the-art 450 MHz RF
front-end design with excellent RF performance. In addition to LTE 450 MHz great perfor-
mance, it allows users to communicate in standard high-speed public LTE networks (LTE
Cat.4) with download speed up to 150 Mbps and upload speed up to 50 Mbps.
The router is equipped with two independently configurable Ethernet ports,RS232 and
RS485 serial ports and with one digital input together with one digital output.
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 (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.
Examples of possible applications
•mobile office
•security system
•telematic
•telemetric
•remote monitoring
•vending and dispatcher machines

1.7 Mounting Recommendations
The router can be placed:
•on a flat surface,
•on a wall using the wall mounting clip (see Chapter 1.8),
•on a DIN rail EN 60715 with the metal DIN rail clip (see Chapter 1.9)
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 2.4.

1.8 Wall Mounting
The wall mounting clip is supplied with the router as standard accessories.
The router can be screwed to a wall (or another surface) using the wall mounting clip.
There are two wholes on the clip with a diameter of 4 millimeters. For detailed information
about the mounting dimensions see Figure 6in Chapter 1.6.
When mounting the wall mounting clip, tighten the screws with max. torque of 0.4 Nm.

ICR-2437
1.9 DIN Rail Mounting
The DIN rail clip is not supplied with the router as standard accessories, but it can be ordered
by the order code BB-DIN-ICR32.
The DIN rail clip is suitable for a DIN rail according to EN 60715 standard only. The default
position of the clip is shown in Figure 8.
When mounting the DIN rail clip, tighten the screws with max. torque of 0.4 Nm.
Figure 8: 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 9.

2. Hardware Functionality
See Chapter 1.3 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 SIM Card Slots
Slots for two SIM cards are located on the right panel of the router under a metal cover. It
is necessary to insert an activated SIM card, to work properly. If the PIN is required for the
SIM, enter it in the router’s web interface. The SIM cards may have different APNs (Access
Point Names) adjusted. The SIM card changing procedure is described below.
Type of SIM cards: micro-SIM (3FF) 15.0 x 12.0 x 0.76 mm.
Inserting the SIM card:
•Always disconnect the router from the power supply before handling the SIM card.
•Unscrew two screws on the SIM card cover and remove the cover.
•To remove an inserted SIM card, use the flat end of a spudger, or your fingernail,
press the SIM card slightly into its slot until you hear a click. After hearing this click,
release the card, and it will pop out of its slot.
•To insert a SIM card push card into the slot until it clicks into place.
•Place back the cover and fix it by two screws.

2.2 Cellular Antennas
Main (ANT) and diversity (DIV) antennas can be connected to the router using the SMA
connectors located on the front panel.
Do not run the router without connected cellular antenna connected to the main antenna
connector as the energy from the transmission is effectively reflected by the open end
and can damage the equipment.
Recommended tightening moment for screwing the antenna to the SMA connector is 0.9 Nm.
The diversity antenna improves the radio capability of the router at low signal strength.
2.3 Ethernet Interfaces
The panel socket of RJ45 is used for Ethernet interface. The pinout of the socket is shown
in Figure 6and described in Table 2.
