323007 - 2 branches viDeo splitter
The device has one input and two outputs . It splits the
BUS signal into two channels: the video signal can only be
transferred from input to output . The video Splitter has
4 gears for video compensation functions . It can provide
compensation to two channels separately and make the
video signal output from EP adapt to different transfer
distances by setting different gears . It mainly use in riser
systems to divide the riser BUS into many channels to adapt
to the wiring in many low electricity wells . One building that
is particularly high will use 323007 to adjust video gains by
splitting in two channels . One channel will be used for lower
floors, the other is for higher floors . 323007 also can be used
for physically connecting the Switchboard and extend the
Switchboard interface . (in this case, if the Switchboard is
fitted with a camera, the video signal cannot be transmitted
to the handset) .
