BSRF ACH-642 Bedienungsanleitung
*
Instructions :
Power : Connect your power cord to IEC(1). The green LED Power On will light up
and the other leds will e tested.
Fi er : Connect one to two remote antennas (AFB-250) on those ports. You can
use monomode Neutrik Opticalcon ca le (this is the est solution) or use
LC/APC patchcord (you must e a le to inspect and clean those
connectors, we suggest to always use a new one).
Be sure you use APC connectors (green connectors) and not PC ( lue
connectors) unless you request a PC adaptation.
When you plug connector to the socket connectors you should hear a little
« click » wich means that it's correctly plugged.
If a AFB-250 is already powered and connected at the other end of the
fi er, as soon as you plug the fi er on the ase,'s the corresponding Optical
In green led will light up continuously. If a led link it means that there is
an optical attenuation etween the AFB-250 and the ACH-642 ( etween 3
and 6 dB).
If a led stays off this means there is no optical signal or the optical
attenuation is a ove 6dB.
RF in : Connect your antennas through 50 ohms coaxial ca les to connectors (3).
DC feed led (5) light if corresponding DC-feed is activated (it mean a 12Vdc
voltage is present at input). If this led link it means there is a short circuit
(It could e connector, ca le...).
If you use active antennas set the gain as mentionned in the manufacturer
documentation (too much gain will increase intermodulation not enough
will reduce RF coverage).
Most passive antenna can e used while the DC feed is active. But if you
plan to use magnetic antennas (loop) you'll have to desa le DC feed.
DC feed can e disa led with switch inside the ase.

RF out : Connect those outputs to your receiver or splitter.
More informations :
-Led Optical On (5) light up if the corresponding optical receiver is
operationnal.
- «Pin out » of Neutrik Opticalcon figure on (2).
-If you plan to not use « coaxial antennas » you should consider to
desactivate DC feed voltage and connect 50ohms BNC loads.
Antennas disposition :
-If you need to optimise coverage in the same space, first try just one pair
of antennas and do some walkaround to check coverage. Then add
another pair of antennas in the area where you want more signal. Redo the
test.
- If antennas from different port are two close from each other, this could
lead to multipath loss. When multipath loss occure you get fast RF
attenuation leading to a fast audio lost and recover. If you does'nt know
much a out it please contact us we'll e pleased to help you on your
project.
