5.11.1 Description

Matrix SW164OSM is a product for professional use in applications for security and surveillance and dedicated
to the management of video signals. It can be used to control 16 input videos; there are four video outputs, one
of which can be managed directly by a VCR. It is used to control the usual switching and alarm management
operations. Refer to the matrix manual for further information on this subject.

5.11.2 Connection

5.11.2.1 Cable
The connection between the matrix and the keyboard is made using an RS232 channel, which limits its length to
about 15 metres. It is necessary to create a connection cable, which is inserted between DB9 on the back of the
keyboard and one of the RJ11 connectors on the back of the matrix.
Alternatively, it is possible to use RS485-RS232 interfaces, which allow a maximum distance between keyboard
and matrix of 1200 metres. In this case the connection diagram is as follows:
