Extron Electronics QSD 204_204D User Guide - Manual (Page 11)

1-3 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).
