QSD 204 • Introduction

Three ways to control the decoder

 —  The decoder’s front panel, a computer or

other RS-232 control device, or the optional IR 901 remote control can all be
used to control the QSD.

Autoswitch mode

 —  When autoswitching is enabled, the decoder will

automatically select the highest numbered input which has an input
present.

Sync polarity selection

 —  The output horizontal and vertical sync polarities

may be set for displays which require specific signal polarities.

Serration pulse removal

 —   LCD displays, DLP projectors, and plasma displays

do not require serration pulses to synchronize retracing.  The serration
pulse can be stripped from the vertical blanking portion of a signal by
using this feature.

RS-232 configuration

 —  The QSD 204 can be configured by using the Extron

control software for Windows, or by using a third party control system.

Versatile mounting options 

—  The QSD 204 is 1U high, and a half rack wide.  It

is rack mountable, or it can be placed on a table or other furniture.  An
optional mounting bracket kit will also allow the QSD to be mounted under
a tabletop or desktop.  Rubber feet and rack mounting hardware are
included.

Options and accessories

The QSD 204’s optional equipment includes:

IR 901 remote control

 —  Extron’s IR 901 (part #70-152-01) is an infrared

remote control which replicates all of the front panel controls of the
QSD 204 except the Menu and Next buttons.

SDI input card 

—  Serial digital interface (SDI) input can be added to the

QSD 204 model by the installation of an SDI input card (part #70-168-01).
