3-port video distributor
The DM2430 is a three-port 'T' distributor
whose purpose is to distribute, depend-
ing on the system topology, the video sig-
nal by connecting two of the three ports
together. In audio-only DUO system, the
device has no effect.

Programming
The configuration phase of the device
only requires that they be set up:
- the extremes of the address range
of all products that are physically
connected to port L1
- the extremes of the address range
of all products that are physically
connected to port L2.
from the line
40 mA
Devices whose addresses belong to
neither L1 nor L2 will be considered as
0°÷+50°C
connected to the LP port.
90% RH
The device can only be configured via
the DUO System app, which is available
for both iOS and Android environments.
The smartphone on which the app is
launched requires a Bluetooth program-
mer (XE2921/XE2922/PGR2991BT) to be
connected to the system to which the
DM2430 belongs.

DM2430
- 4 ranges are available for L1 addresses
and 4 ranges for L2 addresses. In the
case of installations with more than
200 users or in any case divided into
blocks, the extremes (beginning and
end) of the block range over which the
users are distributed must also be set.
The blocks are set for both L1 and L2;
- exit the app and turn all dip-switches
SW1 on the DM2430 back to OFF.

In the system built to serve a series of
small houses or small apartment blocks
located along a private road with 2 main
