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
transport, 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 24V connection
Only use the supplied adapter plug to connect to the 24V DC on-board
power supply of your vehicle.
When connecting the CAR-A-WAN.rail, the power supply of the
CAR-A-WAN.rail must be protected by a 2A slow blow fuse (T) which
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 attachment
The router is intended for mounting in rail vehicles. Special wall brackets
and mounting rails in accordance with DIN EN 60715 TH 15 or DIN EN
60715 G 32 and DIN EN 60715 TH 35 are available to which the
CAR-A-WAN.rail can be attached. See also chapters 7.4 and 15.
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.
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
12
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
13
4.9 Maintenance, service and malfunctions
Repairs may only be carried out by qualified personnel.
Only spare parts that do not alter the safety
regulations of the CAR-A-WAN.rail may be used.
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.rail in the event of
a software update.
Software updates should only be carried out with
sufficiently fast mobile phone coverage, since the
transmission time can be longer than the follow-up
time of the CAR-A-WAN.rail due to the size of the
updates and can therefore be aborted 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.rail is designed to connect computers, laptops, netbooks,
smartphones, electronic cash registers with Internet cash function and
other TCP/IP-capable devices such as webcams from the vehicle to the
Internet:
wired via LAN
wireless via WLAN
The CAR-A-WAN.rail independently dials into the Internet and, if necessary,
reconnects in the event of a disconnection. 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 platform or
other service points) is correct.
In the Plus version, the second WAN connection can be
parallel or
alternatively

Introductory remarks
15
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 have been established as a 3G connection
(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
16
6 System description
The Linux router CAR-A-WAN.rail 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.
The supply with operating voltage puts the CAR-A-WAN.rail into the
operating state.
Two SIM cards are switchable, each connected to a 3G / LTE modem, LEDs
(inside the housing) signal the operating states; one LED can be seen on the
outside to signal the operating state and an existing remote maintenance
readiness (option), 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.

7 Device description CAR-A-WAN.rail
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 long 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 long side of the device there are (from left to right) connections for
power supply, 2* LAN (M12 10/100/1000 MBit/s), the WLAN antennas and
in the second row the connections for the mobile radio modems (WWAN
1-3) and their MIMO connections WWAN 1-3, last GPS.
Power supply (M12, Power):
The power supply connection contacts permanent
plus 12-24V DC, switching plus, ground and earthing.

Device description CAR-A-WAN.rail
18
LAN connections (M12, Ethernet1-2):
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 with the factory configuration.
The Ethernet2 interface is not yet configured on delivery.
Antenna connections (N):
Since the N-antenna connectors do not have any coding,
but only a correct assignment guarantees the function of
the CAR-A-WAN.rail, we recommend making the cable
ends distinguishable before assembly when laying the
antenna cables.
We recommend colour coding using a band of insulating
tape similar to the FAKRA codes used in automotive
engineering:
bordeaux (RAL 4004) -> WWAN1
carmine red (RAL 3002) -> WWAN2
pastel orange (RAL 2003) -> WWAN3
bright blue (RAL 5005) -> GPS
beige (RAL 1001) -> WLAN
You will find sources of supply for the matching colors at
the end of this document, see 15

7.2 SIM card holder in router housing
The SIM card holders are located below and above a small, socketed board
in the router housing.
The SIM cards in Mini-SIM format can only be inserted into the SIM card
holders when the housing has been opened. Please do not insert any
smaller Sim cards (Micro or Nano, these are too small and have no
contact). The use of Sim card adapters is not recommended. Please take
this into account when purchasing and handling SIM cards.
There are two SIM card holders per modem on the board; one is visible
from above and holds the default SIM card; the second SIM card holder is
located directly below. A SIM card inserted there can be used by switching
after a reboot.
If only one SIM card is used, slide it into the visible holder 1-1, 2-1 or 3-1,
with the notch in front and the gold contacts down, until you feel it click
into place. When using two SIM cards per modem, start with SIM card 1-2,
2-2 or 3-2.

Device description CAR-A-WAN.rail
20
If possible, before inserting the SIM cards, touch the
housing at the terminals to the ground strap to dissipate
electrostatic charges. Avoid direct contact with the circuit
board.
Please do not use only the lower SIM card slot. Always
assign an activated SIM card to at least the upper SIM card
slot.
