1. Product Overview
1.1 Product Introduction
Industrial cellular router ICR-2531 is designed for wireless communication in mobile net-
works that use traditional cellular technologies.
The primary purpose of this router is its use in the Category 4 (Cat.4) services on the
cellular LTE network. Cat.4 rated router is capable of achieving typical speeds in 4G coverage
areas where the network is enabled with 20 MHz of contiguous spectrum. The peak downlink
data rate for Category 4 is approximately 150 Mbps. In the uplink, LTE Category 4 provides
a peak data rate of 50 Mbps.
The router is equipped with two independently configurable Ethernet interfaces (ETH0
switch with 3 ports and ETH1 with one port) and with one digital input together with one
digital output. The router can be equipped with a 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 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.
Examples of possible applications
• mobile office
• fleet management
• 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 2.3.

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 5in Chapter 1.6.
When mounting the wall mounting clip, tighten the screws with max. torque of 0.4 Nm.

ICR-2531
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 router under a metal cover. If you intend to use
this device to communicate over a cellular network, please place an activated data-provisioned
SIM card into the SIM card reader.
You can install two SIM cards simultaneously to utilize the switching feature. The SIM cards
may have different APNs (Access Point Names) adjusted. The SIM card changing procedure
is described below. Enter the PIN in the router’s web interface if the PIN is required for the
SIM (Administration -> Unlock SIM Card).
Type of SIM card: 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.
