5.4 Video ma trix SM84A and SM164A
5.4.1 Description
Matrix SM84A and SM164A are products for professional use in applications for security and surveillance and
dedicated to the management of video signals. The SM84A and SM164A models differ only in the number of
possible video input connections, 8 and 16 respectively; there are four video outputs, one of which can be
managed directly by a VCR.
As well as the usual switching, alarm management and on screen menu programming operations, the SM84A /
SM164A matrix is equipped with an optional auxiliary line that can be used to control the telemetry or
multiplexer units. Refer to the matrix manual for further information on this subject.
5.4.2 Connexion
5.4.2.1 Cable
The communication cable is standard, as described in § 3.3 - Standard connection cable, page 12.
5.4.2.2 Matrix settin gs
The new generation matrix SM84A / SM164A can be controlled by different types of keyboard and therefore
emulates the respective protocols: to control the switcher with the DCJ keyboard the MACRO protocol with baud
rate 38400 should be used.
Set the dip switches in the matrix as required (all dips are OFF, with the exception of Macro Protocol, baud rate
38400, programming).
5.4.2.3 Keyboard se ttings
While the keyboard is being set up, the RRQRR submenu should be set as
follows:

Control of a SM164A matrix
The presence of a maximum of four keyboards connected to the matrix means it is necessary to define a
different identification number for each one (from 1 to 4).
5.4.2.4 Operational test
If the keyboard is connected directly with the switcher set up in this way using the telephone cable supplied, it
should be possible to switch the input videos immediately:
