Extron electronic manual Controlling the DVS 304 Devices, DVS 304 Series • Introduction

Buffered video outputs —

•DVS 304 models – Five rear-panel BNC connectors and one VGA-type 15-pin HD connector provide connections for RGB or Y, R-Y, B-Y output. Both outputs are active at all times for simultaneous output.

•DVS 304 DVI models – Five rear-panel BNC connectors and one DVI-I connector provide analog and digital output (DVI-I) and analog output (BNC). All outputs are active at all times for simultaneous output of RGB or Y, R-Y, B-Y. DVI-D output is disabled for RGB pass-though.

Device control — The scaler has four methods of control: by its front panel, via a computer or other RS-232/Ethernet control device, using the optional IR 902 remote control, or via the Signal Processing Products Control Program (SPPCP).

Scaled outputs — The DVS 304 models offer 69 output rates and the DVS 304 DVI models offer 70 output rates.

RS-232 configuration — All DVS 304 series units can be configured by using the Extron control software for Windows® or by using a control system.

Front panel security lockout (executive mode) — To prevent accidental changes to the unit’s settings, the scaler provides front panel lockout of all controls except input switching. A second executive mode completely disables all front panel controls.

3:2 pull down detection for NTSC and 2:2 film detection for PAL video sources

—These patented, advanced film mode processing features help maximize image detail and sharpness for video sources that originated from film. When film is converted to

NTSC video, the film frame rate has to be matched to the video frame rate in a process called 3:2 pull down. “Jaggies” and other image artifacts can result if conventional de- interlacing techniques are used on film-source video. The digital video scaler’s advanced film mode processing recognizes signals that originated from film. The scaler then applies video processing algorithms that optimize the conversion of video that was made with the

3:2 pull down process. This results in richly detailed images with sharply defined lines. A similar process is used for PAL film-source video.

Versatile mounting options — The non audio models are 1U high, half rack wide rack mountable devices. Alternatively, they can be placed on a table or other furniture. Rubber feet are included.

The audio models are 1U high and full rack size and can be rack or desk mounted using included rack or through-desk mounting brackets.

Controlling the DVS 304 Devices

All DVS 304 series devices can be controlled using one or more of the following methods:

•The front panel controls.

•A computer, a touch screen panel, or any other device that can send and receive the serial communications through the RS-232 or Ethernet port. The Extron Simple

Instruction Set (SIS™) is a set of simple keystroke commands that can be used with any such devices, and Extron control software for Windows provides a graphical interface for controlling the scaler from a computer.

•The optional IR 902 remote control, replicating most of the front panel controls.

•Ethernet control via IP Link, enabling the scaler to be controlled and actively monitored over a LAN, WAN, or the Internet.
