4 Safety and security
4.1 General safety instructions
Please read and observe the user manual and the
safety instructions listed in this chapter carefully
before carrying out any further steps such as
transportation, storage, connection, commissioning,
etc.
Work on the router and antennas must only be
carried out by authorised specialist personnel.
4.2 Improper installation
Improper installation can lead to damage to the unit or the vehicle!
Special knowledge and skills are required for the installation of the system.
It is strongly recommended that installation be carried out by a specialist
workshop.
4.3 12/24V connection
Only use the supplied adapter plug to connect to the 12/24V DC on-
board power supply of your vehicle.
When connecting the CAR-A-WAN. 112 the power supply of the
CAR-A-WAN. 112 must be protected by a 1A slow-blow fuse (T) that cannot
be switched on again.

Safety and security
11
4.4 Mobile radio antennas
The installation of mobile radio antenna cables on vehicles is not
recommended without expert knowledge and suitable tools.
Poorly assembled or arbitrarily shortened or extended high-frequency
antenna cables can have poor reception and transmission performance and
interfere with other equipment.
Unadjusted, minimal bending radii of antenna cables can lead to breakage
of the core of antenna cables. Poor reception and transmission power can
be the result.
4.5 Device mounting
The router is intended for mounting in motor vehicles. It can be mounted
directly:
on aluminium housing (with four screws Ø 4mm arranged in square,
edge length 145mm)
145mm
145mm

Safety and security
12
or via the already installed housing bracket of the v3/v4.
Never set up or operate the device in a damp environment. Liquids
must also be kept away from the device.
The router must not be mounted near heat sources, as the aluminium
housing must be able to dissipate heat.

Safety and security
13
4.6 Risk of injury
Unsuitable installation locations, missing or insufficiently fixed
brackets can cause injuries in the event of a traffic accident.

Safety and security
14
4.7 Risk of damage & injury during installation
When removing panels, sharp or pointed tools can cause injury and
material damage.
Always loosen parts carefully. Do not apply direct pressure to the
connection cable.
4.8 Damage to important vehicle parts
When drilling mounting holes or driving in sheet metal screws, important
vehicle parts or lines can be damaged.
Ensure that there is sufficient clearance behind the screw and drill holes.

Safety and security
15
4.9 Maintenance, service and malfunctions
Repairs may only be carried out by qualified personnel.
Only those spare parts may be used which comply with
the CAR-A-WAN.112 do not change.
The operating system is an integral part of the
certification process. When using an operating system
not released by IPmotion, there is a risk that the
certification will become invalid. If necessary, the tests
underlying the certification must be carried out again
and, if necessary, the prerequisite for this must be
reassessed.
Software updates should only be installed according to
instructions and when the power supply has been
secured. An interruption of the power supply can lead
to a total failure of the CAR-A-WAN.112.
Software updates should only be carried out with
sufficiently fast mobile phone coverage, since the
transmission time is longer than the follow-up time of
the CAR-A-WAN.112 due to the size of the updates and
could therefore be terminated prematurely.

5 Introductory remarks
This manual is intended to provide basic information about the router with
integrated wireless LAN hotspot to be installed in the vehicle, namely the
operating principle, the application of the various functions and what to do
in the event of malfunctions.
This manual also contains information on configuration, handling and
installation.
The contents of this device description may change due to advances in
technology. We have made every effort to ensure that the content is
correct and clear.
Should we nevertheless have made mistakes, we are grateful for any
information.
We assume no liability for errors in this description and the resulting
consequences.
The CAR-A-WAN. 112 is designed to connect computers, laptops, netbooks,
smartphones, electronic cash registers with Internet cash function and
other TCP/IP-enabled devices such as webcams from the vehicle to the
Internet:
wired via LAN
wireless via WLAN via WLAN antenna 1 (connected to W1 and W1M)
The CAR-A-WAN. 112 automatically dials up to the Internet and, if
necessary, dials up again if the connection is interrupted. Furthermore,
dial-in rules can be taken into account, such as a roaming lock or minimum
signal quality.
The WLAN antenna 2 (connected to W2 and W2M) functions as a WLAN
Ethernet client and establishes the mobile radio connections automatically
if the WPA2 connection of a stored WLAN (e.g. that of the station or other
service points) is correct.
In the Plus version, the second WAN connection can be
parallel or
alternatively

Introductory remarks
17
In the Trio version, the second or third WAN connection can be
parallel or
alternatively
to secure the availability of the connection.
Three concurrent connections are used as a parallel connection and new
connection requests are distributed across the three connections,
maintaining a path once taken to terminate the individual WAN connection
previously used.
If these WAN connections are 3G (HSPA) and a connection switches to LTE,
all traffic can be redirected to the faster, alternative connection while the
slower connection is disabled. The higher-value connection speed is
allowed to dial in.

System description
18
6 System description
The Linux router CAR-A-WAN. 112 connects local devices connected via
LAN or WLAN to the Internet using up to three data modems. System rules,
such as user-defined rules, control the dial-in behavior.
The power management controls the follow-up time and the almost
complete disconnection from the 24V DC power supply, or correct cold
starts during a manual restart or triggered watchdog of the embedded PC.
Two SIM cards are switchable, each connected with a 3G / LTE modem,
LEDs (inside the housing) signal the operating states, a speaker can emit
warning tones, an optional, tactile switch can trigger the reset of the
router.
The modems transfer their operating heat to the aluminium housing. Plug
connections for the connection of power supply and antennas facilitate
installation and allow installation and removal without tools.

In this chapter, the corresponding device elements are explained and you
receive the instructions for operation as well as all information on the
device connections.
7.1 Elements on the front side
WWAN means Wireless Wide Area Network, also known as
3G (UMTS), LTE, 4G.
M stands for MIMO. MIMO technology increases reliability
and data throughput.
On the front of the device you will find (from left to right) connections for
2* LAN (RJ45 10/100/1000 MBit/s), a concealed reset button that can only
be pressed with a paper clip, an LED for indicating the operating status, 2*
USB connections and the pin tray for connecting the power supply cable.

The power supply connection contacts permanent plus 12-
24V DC (clamp 30), as well as switching plus (clamp 15) and
ground (clamp 31).
LAN connections (RJ45, Ethernet 1-2):
The Ethernet1 and WLAN interfaces are mutually bridged,
i.e. you can also connect your devices to LAN instead of
WLAN. Devices connected to the LAN can communicate
with devices connected to the WLAN. The clients are not
isolated from each other. The Ethernet2 interface is not yet
configured on delivery.
7.2 Elements on the back
On the back of the device, in the upper row, you will find the connections
for the mobile radio modems (WWAN 1-3) and their MIMO connections
WWAN 1M-3M and GPS. The lower row contains the connectors for the
WLAN antennas W1/W1M and the CAN connector.
