2. SOFTWARE CONFIGURATIONS (ONLY WITH ART. 69MD)
The configurations can be made only via the programming module
Art. 950C connected to the serial socket inside art. 69MD (see Fig.
2). Alternatively it is possible to use the interfaces Art. 692I or 692I/U
and the PC software SaveProg (Art.69CD). The configurable para-
meters are:
1. GENERAL INFORMATION
Articles 69MC and 69MD are interfaces on a 4 module DIN enclo-
sure that enable converting (extracting) the audio and video signal
from an ELVOX TWO-WIRE bus line. Art. 69MC always extracts the
audio and video signal, when available in the two-wire bus, regar-
dless of the flat called. Article 69MD extracts the audio and video si-
gnal when a valid signal is available in the two-wire bus of one or
more flats programmed in article 69MD. For the programming it is
necessary to use art. 950C or PC. By default art. 69MD has all 200
flats active for extracting the audio/video signal Every time art.
69MC and 69MD are activated to extract the video signal they close
a normally open contact.

The power is supplied with art. 6582 to keep the circuit isolated. The
jumper CN1 with 3 positions A,B,C is the terminator of the bus for
the video signal and is used in the same way as all the other ELVOX
TWO-WIRE products: in the case of a feedthrough bus keep CN1 on
A, otherwise terminate on B or C according to the best position for
the video output. R91 regulates the output audio level. It is already
set in the factory to supply 0.5Vpp and must not be changed unless
absolutely necessary. R52 regulates the output video level. It is al-
ready set in the factory to supply 1 Vpp and must not be changed
unless absolutely necessary.
The terminal block CN2 has the following signals and controls:
