Quantity Description

2 Transceiver optoLAN

1 Duplex multimode optical fiber 62,5 / 125µm

2 Chargers (standard)

1 Manual (english)

2 External battery packs (optional)

The shipment includes charged batteries However, due to the self-

discharging of NiMH-batteries they should be recharged again before use

Read chap 4 (Maintenance) before charging the devices!

2 Characteristics

The digital optical system optoLAN can be used to optically transmit

ethernet (10/100 Mbit) signals Because of the optical transmission, the

system is very robust against EMS (electromagnetic susceptibility) It can

withstand high electric and magnetic fields, like they appear in EMC-tests

The system also is optimized for low noise emission

Power is supplied by internal NiMH-batteries which make the system easy

to use The optoLAN is prepared for the use of external batteries (with

optional battery pack)

Read chap 4 before

charging!

3 Field of application

•Transmission of ethernet signals up to 10/100Mbit/s during EMC-

tests

•Transmission of ethernet signals over long distances without signal

loss (up to 100m or more, depending on timing requirements)

•Handle ground potential problems

Maintenance

Recharge batteries after use with the enclosed charger To prevent a lazy

battery effect, discharge the devices every 5 times completely by using the

automatic switch off (Leave the system on, until it turns off automatically)

Afterwards, charge the devices as usual

The devices have to be turned off before connecting to the charger If this

is disregarded, the system might get damaged!

Fig 4 1 shows the pinning of the charge connector Chargers have to be

connected to pin 2 (+) and pin 4 (GND) An external supply (6…8V, 0 5A)

can be connected to pin 3 (+) and pin 4 (GND) Use only power supplies

which are certified by mk-messtechnik.

Maximum charging

current is 1 A

connecting to

charger, or else the

system might get

The included chargers are not meant to power the transceivers during

operation The transceiver outside the shielded room can be run with an

external power supply (optional) The internal transceiver can be run with

an external battery, if needed (optional) Do not use the external power

supply or charger to power the transceiver inside the shielded room while

EMI-tests are running This might damage the transceiver!

Due to self-discharge issues with NiMH batteries, recharge batteries before

use, if the system has not been used for a longer time

Do not use cleaning agents or solvents to clean the devices, only use a

slightly moistened, soft cloth

Do not open the devices, as there are no parts inside which have to be

maintained The opened housing can pose a fire hazard through short-

circuit currents! Please contact your distributor or the manufacturer if you

have any problems Send in the complete system (both transceivers), if a

problem cannot be solved by turning the devices off and on again or by

checking the positions of the switches Please contact us in any case

before sending in the devices.

Do not open the

devices!

Short cut / fire

hazard!

Do not use charger

or power supply

during EMI-test!

5 Trouble shooting

The following trouble shooting list is provided to assist you while having

problems It might let you use the system again without a long down time:

Error: Possible reasons: Solution:

No or erroneous

transmission

Receiver does not

receive an optical signal

Cables damaged or not

attached properly

Wrong optical fibers

(diameter)

Low battery

System turned off

Check optical fibers and

connections, change

fibers if necessary

Connectors and cables

regarding damages

Use fiber with

62,5/125µm

Charge batteries

Turn on all devices

Transmission stops Low battery

No optical signal at

receiver

System turned off

Charge batteries

Check for light at optical

output Replace optical

fiber

Turn on all devices

Device cannot be

turned on, cannot be

charged

Batteries damaged

Internal fuse is broke

Charger or cable

damaged

Batteries

over discharged

Send device to us

Check / replace charger

and charging cable

Charge batteries,

maybe use other

charger (5 battery cells)

Common problems Defective optical or

electrical cables or

connectors

Check connectors, fibers

and cables Test with

other ones

Replace cables

Appendix: Details and operation

The following chapter descri es special details of the optoLAN system for

the transmission of ethernet signals. The system consists of two

transceivers.

a) Housing and connectors / switches

Fig. a.1 shows the front side of the transceivers with connectors and

switches:

•power push utton with control LED (Pwr On/Off)

•attery information LED (Info)

•charge plug (Charge)

•optical connector FSMA (Optical In .. Out) for duplex multimode

fi er (62,5/125µm)

Fig. a.2 shows the rear side of the transceivers with RJ45 connector.

(standard ethernet pinning):

•RJ45 plug LAN I/O 10/100Mbit/s for the ethernet signals to e

transmitted.

b) Operation and handling of the optoLAN

•Set up the devices at the dedicated places. The transceiver

connected to the PC can e powered y the power supply (optional)

all the time, if there is no need for attery supply (EMC issues). The

transceiver inside the cham er eing connected to the DUT does

not have to e powered y a power supply during testing (might get

damaged)! It has integrated atteries to run the system.

•Connect the transceivers with standard ethernet ca les (without

crossing) to the PC and the DUT. Inside the a sor er lined cham er,

the ethernet ca le should e as short as possi le with a good

shielding (e.g. CAT 6 or higher) to avoid rf coupling into the system.

•Connect the optical fi er (Out => In; In => Out). Only use

62,5/125µm multimode fi ers.

•Connect the electric ca les

•Turn on all devices (power push utton, see Fig. a.1); the order does

not matter

•The transmission starts automatically after a short initialization.

If the transmission suddenly stops after a long duration of measurement,

check the Info LED of the transmitter (see Fig. a.1).

If the attery power falls elow 5,2V, the Info LED is switched on. The

system should e reloaded soon. Below 4,5V, the system is turned off

automatically.

The measurements can e extended y using the optional attery pack

(BP-60) with connector ca le or a power supply certified y mk-

messtechnik. The external supply can e connected to the system any time

(parallel). The connection to the internal attery is decoupled with a diode.

Only use the attery pack and connector ca les from mk-messtechnik!

Others might lead to a damage of the system!

Check info L D if

transmission stops

suddenly!

Only use battery

packs and connector

cables provided

from mk-

messtechnik. Other

modules influence

MS-performance

and might damage

the opto-system!

The use of the

external filter is

essential for MS-

tests!

Use short, shielded

ethernet cables with

1:1 pinning!

(no crossing!)
