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.
