2.7 WLAN (Wireless Local Area Network)

2.7.1 Important information on WLAN

WLAN stands for Wireless Local Area Network. As with Bluetooth, WLAN provides a radio link on the free

2.4 GHz ISM band (ISM: Industrial, Scientific, Medical). This frequency range is subject to government regulations, but may be used without a license in most countries. Consequently a large number of applications and devices employ this frequency band for transmission. This can result in frequency interference. Depending on ambient conditions, the WLAN link may therefore deteriorate, e.g. in the case of Bluetooth links, cordless telephones, radio-controlled thermometers, radio-controlled garage door openers, radio-controlled light switches or radio-controlled alarm systems.

i Bluetooth can lead to interference in the bandwidth

of the WLAN network. The antennas of Bluetooth and WLAN devices should be at least 30 centimeters apart. Do not plug Bluetooth USB adapters and WLAN sticks into adjacent USB slots on PCs/laptops. Use the USB extension cable (special accessory) to maintain a distance between the Bluetooth USB adapter and the WLAN stick on the PC/laptop.

i Exercise extreme caution if wearing pacemakers

or other vital electronic devices when using radio systems, as proper functioning of these items could be impaired.

Note the following to ensure the best possible connectivity:

R The WLAN radio signal always tries to find the most

direct path. When setting up the PC/laptop and access point (see section 2.6.2), make sure there are as few obstacles as possible (e.g. steel doors and concrete walls), which could interfere with the radio signal from and to the KTS 340. Inside buildings, the range of the WLAN is also greatly influenced by the construction materials used. Conventional masonry, wooden walls and certain types of dry construction wall scarcely impede radio waves. Thin gypsum walls can however cause problems, as considerable amounts of moisture may accumulate in the gypsum and result in the absorption of radio signals. Concrete (and in particular reinforced concrete) largely blocks out radio waves. Cellar ceilings are often impenetrable. Generally speaking, walls with a lot of installed metal (e.g. pipes, wires) obstruct radio waves.

R Radio reception is also impeded by large metal

objects such as radiators and window frames as well as active sources of interference such as DECT telephones and microwave ovens.

R Have your network infrastructure installed and

tested in advance by a data systems expert.

R Keep the SSID and the codes for the radio link in a

safe place. Make sure these data are readily to hand in case faults occur.

R We recommend a thorough inspection of the pre-

mises on commissioning: Establish where in the building the KTS 340 works properly and where the operating limits are.

R If the KTS 340 is to be used in a vehicle (Faraday

cage), radio communication can be severely limited.

R The radio link is affected by weather conditions. The

reception signal may therefore vary.

R Please contact your network administrator with any

queries.

2.7.2 Information on access points

A wireless access point is an electronic device, which acts as an interface between a radio network and a cable-connected computer network. It provides a wireless connection between the KTS 340, the PC/laptop with ESI[tronic] Startcenter and a printer, for example.

i We recommend using WLAN standard IEEE 802.11g

(data transmission rate max. 54 Mbps) for the access point. The "extended range" function is not supported.

Please note the following:

R The access point should be located as centrally and

high up as possible, ideally under the ceiling.

R The access point antenna should face downwards

towards the floor.

R In the event of a poor connection it may be useful to

change the set channel on the access point. If possible, avoid using neighboring channels to channels that are already in use.

R We recommend that encryption of radio communica-

tions is configured at the access point.

2.7.3 Information on WLAN for USA and Canada USA:

Changes or modifications not expressly approved by the party responsible for compliance could void the user’s authority to operate the equipment.

Canada:

Operation is subject to the following two conditions:

R this device may not cause interference, and R this device must accept any interference, including

interference that may cause undesired operation of the device.

This Class [B] digital apparatus complies with Canadian ICES-003.

R A vehicle-specific adapter cable

(special accessory).

5.2 Switching on

¶ Switch on the KTS 340 with the On/Off button.

"After the system has started, the KTS 340 remains

in the "Vehicle identification" start screen. The start screen is always displayed after switch-on.

! If the KTS 340 is supplied with power via the power

supply unit, always use the power supply unit provided. Do not use power supply units with less power than 15V/3A, such as those supplied with the KTS 200 or KTS 5xx, for example.

The KTS 340 is usually supplied with power via the OBD diagnostic socket in the vehicle. If you do not know where in the vehicle the OBD diagnostic socket is located, we recommend finding it by means of KTS 340 control unit diagnosis.

i In some vehicles, the cigarette lighter socket only

supplies power when the ignition is turned on.

i If a test step involves starting the engine, the battery

voltage may drop to such an extent that supply via the vehicle is no longer guaranteed. In such cases it may be necessary to supply the KTS 340 via the power supply unit.

i In some vehicles, the ignition must be switched on in

order for power to be supplied via the OBD interface.

If the KTS 340 is connected to a PC/laptop via the USB connecting cable, we recommend supplying it with power via the power supply unit provided.

5.3 Switching off

¶ Press the On/Off button for approx. three seconds.

"The KTS 340 is switched off.

If it is only being run off the battery, the KTS 340 is switched off if the battery voltage drops below 8 V or if the device has not been used for ten minutes (factory setting). If the KTS 340 is being supplied via an external power source (e.g. OBD diagnostic cable or power supply unit) and is not used for a lengthy period, the brightness of the LCD touchscreen is reduced.

5.4 Notes on multimeter

Danger from high voltage!

There is a risk of potentially fatal voltage if measurements are taken without a ground cable.

¶ If no diagnostic cable is connected, use the

ground cable provided to make a ground connection between the KTS 340 and vehicle ground before taking U, R or I measurements.

¶ Connect the ground cable as close as pos-

sible to the object to be measured.

¶ Only use the KTS 340 on the vehicle and not

for measurements involving voltages > 60 V.

¶ Do not perform any measurements on igni-

tion systems.

¶ Only use the test cables provided (with

contact protection).

¶ Always plug in the test cables at the

KTS 340 first and then on the vehicle.

¶ Do not lay unshielded test cables close

to sources of major interference such as ignition cables.

5.5 Touchscreen with stylus

The touchscreen of the KTS 340 is operated with the stylus. Touch the application you require with the stylus.

i You can perform "Touchscreen calibration" in the

Service menu Service". To avoid errors, your eyes must be vertically above the calibration points. Click on the calibration points as accurately as possible.
