2. Installation and operation
2.1 System overview
The KiWLAN Type K3877 module enables wireless com-
munication access to the CrashLink2 bus. Working as an
Ethernet to WLAN bridge, it transmits data to and from
all devices connected to the CrashLink2 bus to a wireless
network provided by an access point.
Fig. 1: KiWLAN Type K3877
Fig. 2 depicts a simplied overview of elements and
interfaces of the KiWLAN. The two main parts are the
internal electronics that serve the CrashLink2 bus and
a 3rd party module (named "WLAN module" below), that
implements the Ethernet-WLAN bridge. The internal elec-
tronics monitors the battery, controls the internal charger
and a row of eight LEDs that display the actual state of
operation. The module itself is highly congurable to
work in a wide range of wireless LAN applications and
canbe setback toa dened state by using the "Reset"
button if necessary. Mounting the provided antenna to the
corresponding connector extends the possible distance
between the WLAN module and an access point. The
additional battery supplies the KiWLAN if power supply
via CrashLink2 bus fails.

2.2 Power supply requirements
Please use only power supplies as recommended below
to avoid damage to or malfunction of your KiWLAN.
The KiWLAN has internal DC/DC converters that will ope-
rate from a power supply voltage of 20 ... 60 V.
The maximum power consumption of a KiWLAN is 10 W.
The required current capacity of the power supply is cal-
culated as:
=

, where U is in the range of 20 ... 60 V
U20 V 48 V 60 V
I0.5 A 0.21 A 0.17 A
In case of an emergency, it must be ensured that the
CrashLink2 interface is freely accessible to disconnect
the DC input from the device.
2.3 How to connect the KiWLAN
There is only one CrashLink2 connector. The KiWLAN
therefore has to be installed always at the end of a
CrashLink2 chain as shown in the following picture.

K3877_002-874e-05.20Page 10
Fig. 4: Installing KiWLAN at the end of CrashLink2 chain
2.4 Battery handling
The KiWLAN includes a cell protection circuit and a batte-
ryelectronicwhichiscontrolledbytheKiWLANrmware.
The charge level state can be monitored from the Crash-
Designer software. If the KiWLAN is powered, the battery
will be charged without user interaction. The charge logic
is handled by the KiWLAN itself.
When the KiWLAN is armed the battery will be enabled to
power the device by itself. In case of an external power
failure, operation of the KiWLAN is secured for at least 30
minutes, assuming the battery charge level is higher than
95 % when arming.
2.5 Battery cell replacement criteria
The state of health is an important battery parameter
which represents the batteries ability to deliver electrical
energy, compared to a new battery. The state of health
can be checked by using the DeviceMaintenanceTool or
the CrashDesigner software. Depending of the intensity of
use, it is recommended to regularly check the actual state
of health of the battery.
It is recommended to do a service cycle of the battery
with the DeviceMaintenanceTool every year. If the state of
health falls below 80 % after a full service cycle, then the
battery should be replaced.

3.3 States of operation
Fig. 16inAppendixshows asimplied state machineof
the states described in this chapter.
The KiWLAN can be turned on by connecting it to a pow-
ered CrashLink2 bus. When activated, there are four pos-
sibleoperationalstates(INIT,IDLE,ARMEDandERROR)
that are described in the subsequent sections.
Functional description
Page 13K3877_002-874e-05.20
3.3.1 INIT state
After power up, the KiWLAN enters the INIT state. Its
internal sensors are initialized, an internal self-test is
performed and a rmware update is done if available.
Afterwards, an initial self-test is performed including a
load test of the battery. As long as no error is detected, the
KiWLAN will enter the IDLE state. Otherwise, the KiWLAN
will enter the ERROR state.
When leaving the INT state without any error, the OPER
LED is turned on.
3.3.2 IDLE state
The IDLE state is the main KiWLAN state where the fol-
lowing actions are executed periodically:
check of internal voltages and temperatures
automatic control of battery charging
To ensure proper operation, the internal voltages are mo-
nitored for overvoltage and undervoltage conditions and
the temperature inside the housing is checked for over-
temperature. Any excess of the allowed range of the inter-
nal voltage or internal temperature will force the KiWLAN
to enter the state ERROR.
As long as the KiWLAN is connected to a powered
CrashLink2 bus, charging of the battery is controlled auto-
matically. If the actual state of charge of the battery drops
below 95 % of the full charge capacity the internal charger
will be enabled. Charging will be stopped if the battery is
fully charged.
The battery is not activated in the IDLE state, thus
KiWLAN will turn o if CrashLink2 is not powered or
disconnected.
3.3.3 ERROR state
Any failure during the initial self-test in state INIT or the
cyclic check in state IDLE and ARMED will cause the
KiWLAN to enter into state ERROR. In this state the error
LED (ERR) is blinking and if the battery was charged
before, charging will be stopped. The KiWLAN will stay
in this state until the next power cycle is successfully
completed.
CrashLink2 WLAN converter KiWLAN Type K3877
K3877_002-874e-05.20Page 14
3.3.4 ARMED state
When using the KiWLAN with CrashDesigner software, it
can be commanded to enter the state ARMED. The beha-
vior is similar to state IDLE. In addition to the state IDLE
chargingwillbesuspendedandthepostT0turnodelay
can be set by CrashDesigner. If T0 trigger is detected the
T0 LED will go on and remain on until it is reset by Crash-
Designer.
The post T0 trigger runtime function works as follows: The
valuefortheturnodelay(default180s)mustbesetby
CrashDesigner in advance. After a T0 trigger is received
by the KiWLAN, an internal countdown starts. After the
programmed time has elapsed, the internal battery is swit-
chedo.Thisresultsinanimmediatepowerdownifthe
KiWLAN is not supplied to CrashLink2. If the supply via
Crashlink2 is available, KiWLAN returns to state IDLE.
During the post T0 countdown the CrashDesigner can re-
set the KiWLAN from state ARMED to state IDLE before
the programmed time has elapsed.
When the KiWLAN is armed the battery will be enabled
to power the device. In case of an external power failure,
operation of the KiWLAN is secured for at least 30 minu-
tes, assuming the battery charge level is higher than 95 %
when arming.
Every communication between CrashDesigner and the
KiWLAN(exceptforthe"resettostateIDLE"command)
makes the internal countdown start from the beginning.
Therefore, the KiWLAN will not shut down before commu-
nication stops and the countdown expires.
3.4 CongurationoftheWLANmodule
As mentioned in chapter 2.1, the KiWLAN use a 3rd par-
ty module for the WLAN communication. At time of ship-
ment, the module is precongured with either a xed IP
address dened by Kistler (172.22.87.1) or by customer
specication.Furthermorethedesiredoperatingfrequen-
cy2.4GHzor5GHzissetandthemoduleiscongured
