b) Operation and handling of the opto LAN
•
Set up the devices at the dedicated places. The transceiver
connected to the PC can be powered by the power supply (optional)
all the time, if there is no need for battery supply (EMC issues). The
transceiver inside the chamber being connected to the DUT does
not have to be powered by a power supply during testing (might get
damaged)! It has integrated batteries to run the system.
•
Connect the transceivers with standard ethernet cables (without
crossing) to the PC and the DUT. Inside the absorber lined chamber,
the ethernet cable should be as short as possible with a good
shielding (e.g. CAT 6 or higher) to avoid rf coupling into the system.
•
Connect the optical fiber (Out => In; In => Out). Only use
62,5/125µm multimode fibers.
•
Connect the electric cables
•
Turn on all devices (power push button, 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 battery power falls below 5,2V, the Info LED is switched on. The
system should be reloaded soon. Below 4,5V, the system is turned off
automatically.
The measurements can be extended by using the optional battery pack
(BP-60) with connector cable or a power supply certified by mk-
messtechnik. The external supply can be connected to the system any time
(parallel). The connection to the internal battery is decoupled with a diode.
Only use the battery pack and connector cables from mk-messtechnik!
Others might lead to a damage of the system!
Check info LED if
transmission stops
suddenly!
Only use battery
packs and connector
cables provided
from mk-
messtechnik. Other
modules influence
EMS-performance
and might damage
the opto-system!
The use of the
external filter is
essential for EMS-
tests!
Use short, shielded
ethernet cables with
1:1 pinning!
(no crossing!)
