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.
