5.5 Video Matrixes SM84A and SM164A VIDEOTEC
5.5.1 Description
The SM84A/SM164A matrixes are products for professional applications in the security and surveillance
sector, and are intended for the management of video signals. The SM84A and SM164A models differ only in
the number of input videos it is possible to connect (8 and 16).
There are four output videos and one of these can be operated directly by a VCR.
The SM84A/SM164A matrix can be used for switching, alarm management and on screen menu programming
functions and is also provided with an optional auxiliary line that can be used for telemetry or multiplexer unit
control. Refer to the matrix manual for further relevant information.
5.5.2 Connection
T he communication cable is the standard cable ( see § 3.3 - One keyboard per line: standard connection
cable, pag.16 ).
Configure the DIP switch inside the matrix appropriately (all dips are OFF: Macro Protocol, baudrate 38400,
programming disabled).
5.5.3 Configuring the keyboard
During keyboard configuration, the COMUNICATIONS / VIDEO submenu ( see § 4.2.3.1 - Video, pag.22),
should have the following settings:

(*) If more than one keyboard is connected to the switcher this means different identification numbers should
be defined (from 1 to 4) for each keyboard.
(**) If required select the type (see § 4.2.4.4 - External multiplexer , pag.33)
5.5.4 Operational test
If the keyboard is connected directly with the switcher configured as above, using the telephone cable supplied
with the keyboard, it should be immediately possible to switch the input videos using the video/telemetry
controls.
