. The device, controlled by the commands
coming from the DUO digital line, allows for the
selection of up to 4 or 7 surveillance cameras and/
or the activation of other services. The relays of the
device switch cyclically every time the selector
receives the activation address of the cyclic
operation, or you can select the individual outputs
by sending to the device the address of the output
to be switched.

PROGRAMMING
Functions of the LED’s, buttons and micro-switches during the programming phase
LED’s LI2-LI3-LI4. Indicate which
output (1÷4D/E with common CD and
CE) is being programmed.
J1. Connector for a system programmer.
LED’s LO2-LO3-LO4. Indicate which
output (1÷4A/B with common CA and
CB) is being programmed.
SW1 - SW2.
Micro switches that allow:
- the activation of the only outputs connected
during the cyclic operation;
- entry of the addresses during programming.
Range RG1÷RG4.
LEDs indicating the confirmation of the correct
programming (cyclic or fixed light) or normal
operation (flashing light).
SKIP button. Allows:
- to access programming;
- to select the type of programming;
- to exit programming.
OK button. Allows:
- to confirm the programming;
- to access and change the setting from 4- to 7-
exchange.

With this setting the
outputs with the same
number are simultan-
eously enabled (1A/B/
D/E, 2A/B/D/E, 3A/B/
D/E, 4A/B/D/E).
With this setting, you need to connect
the outputs 1D and 1E respectively to
the common CA and CB; the outputs
are enabled independently (1A/B, 2A/
B, 3A/B, 4A/B, 2D/E, 3D/E, 4D/E).
