The EXI 3508 multi-switch (with integral modem) should ideally be operated in combination with the EXI 01 free-
standing modem. The terrestrial distribution system of this multi-switch is specially matched to this application and
thus offers especially long range capabilities for the installation (> 700 m for the data range). An integral high-pass fi lter
for the terrestrial input prevents undesirable propagation of your network data from a connected antenna.
To achieve optimum performance, make sure that all components of the overall distribution system (including the outlets
used) support the frequency range of 5 to 68 MHz.

fl
y press the “Pairing” button. The two modems exchange a secret network key
and connect to each other. You must press the second button within approx. three minutes after the

the procedure is complete, both LEDs light up continuously again. Each further modem can be added to the
private network in the same way. The pairing can be started at any modem on your private network.
Resetting:
Pressing the “Reset” button resets the modem to its factory settings. Since this also restores the original factory setting
for the network key, the modem is now once again generally visible and no longer belongs to your private network.
Stand-by:
After a few minutes with no data traf
fi
c, the modem switches itself automatically into stand-by mode. The “Power” LED
fl
ashes slowly (red - green).
