DV2424Q
. Active line distributor Allows
the riser signal line to be distributed to 4 de-
rived lines with Zhero series internal stations
and the EX3252 videointercom. It is with
terminal (J1) that let you adjust the line imped-
ance according to the installation requirements.
For each derived output there is a red led
which, when ON, indicates that transmission of
the video signal is enabled.
