Examples of programming
1 videointercom connected to each of the line L1
and L2
4 videointercoms, with sequential addresses, connected to L1 line and 1 videointercom connected to line L2
(*) On the line L1 (numerical interval F1) video signal is delivered to VC1 videointercom.
(**) On the line L2 (numerical interval F1) video signal is delivered to VC2 videointercom.
(*) On the line L1 (numerical interval F1) video signal is delivered to VC1, VC2, VC3 and VC4 videointercoms with sequential addresses.
(**) On the line L2 (numerical interval F1) video signal is delivered to VC5 videointercom.

4) set OFF the microswitch 1 of SW1. This operation ends the
programming phase of the numerical interval F1 of line L1
5) if required proceed in a similar way to program numerical intervals
F2, F3, F4 and F5 of line L1 repeating the instructions reported on
points 2) and 3) and paying attention to set properly the microswitches
of SW1 according to the numerical interval to be programmed (see
table 4.1 on page 4.5)
6) if required proceed in a similar way to program numerical intervals
F1, F2, F3, F4 and F5 of line L2 repeating the instructions reported
on points 2) and 3) and paying attention to set properly the
microswitches of SW1 according to the numerical interval to be
programmed (see table 4.1 on page 4.5)
7) set OFF all the microswitches of SW1 and exit the programming
mode moving jumper J2 from position 2-3 to 1-2; red LED comes
back flashing slowly
8) verify the correct operations of videointercoms connected to lines
L1 and L2.
Programming for exchanger operation
The DV2422A distributor, to be able to switch the video signal from
the main line or from the secondary line, must be programmed to
function as an exchanger; to perform this operation, proceed as
follows:
- access programming by moving the jumper J2 from the position 1-2
to 2-3; the red LED flashes quickly;
- program the numeric intervals assigned to the L2 line as shown in the
product instruction manual (insert the same address assigned to the
secondary external station - e.g.: address 235);

- move the jumper J2 from the position 2-3 to 1-2 to exit the programming;
the led returns to blinking slowly;
- move micro-switch 1 of SW1 to the ON position; the micro-switches 2,
3 and 4 must remain in the OFF position;
- with the last operation the device is programmed as an exchanger and
the led starts double blinking.
This programming is available from version 400 or higher of the
DV2422A distributor.
Memory erasing
To erase all the data stored in the memory of the device it is necessary:
- move the jumper J2 from position 1-2 to 2-3; red LED starts flashing
quickly;
- set ON the microswitches 1,2 and 4 of SW1 (see table 4.1, page 4.5);
- wait for about 4 seconds; red LED lights up continuously
- within 4 sec. set ON the microswitch 3; red LED turns OFF for about 2
sec. and than starts again flashing quickly
- at this stage all the data have been erased
- set OFF all the SW1 microswitches
- move the jumper J2 from position 2-3 to 1-2; the led returns to blinking
slowly.
