Russound VIDEO MATRIX VM1 - Manual (Page 5)

INTRODUCTION
Control Methods
The Video Matrix is controlled by the system to which
it is connected. It switches video sources to the
zones by receiving source selection commands from
the the host system.
The VM1 provides a choice of ports for receiving
control data from the host system: two RJ-45 jacks
for linking to a Russound RNET multiroom system; a
DB9 serial connector; and a USB connector.
RNET communication
When connected through the RNET port, the Video
Matrix monitors the RNET system’s communication
bus and responds to source selection events for
sources 1 through 6 from zones 1 through 8. (In a
system with multiple six-zone controllers, zones 7
and 8 are zones 1 and 2 on controller 2.) With the
CAV6.6 system, it also responds to selection of the
Front (Aux) A/V Input (source 7). This permits the
Video Matrix to distribute that source instead of run-
ning a separate video cable from the source to the
display and selecting it at the display.
The 4x4 configurations of the VM1 respond to source
selection commands for sources 1 through 4 only.
RS-232 communication
The DB9 serial port allows control of the Video Matrix
from a home automation and control system such as
AMX or Crestron. In this application, the VM1 uses
RS-232 command strings for source selection. The
RS-232 command protocol for the VM1 is available
from the Document Center at www.russound.com.
USB communication
The USB port is for control devices that do not have
DB9 legacy connections. It uses the same RS-232
command strings as the DB9 port.
