Options and accessories

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.

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).
