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. 16in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-
