Extron electronics Extron P/2 DA2xi User Manual page 2

Introduction
The P/2 DA2xi and the P/2 DA2xi MT are distribution amplifiers
that accept video input from a VGA, XGA, or UXGA compatible
PC and distribute the signal to separately buffered outputs. Each
output can be extended with Extron VGA Mini-HR cables from 6'
to 250' in length. The MT model also has audio input and output.
Both models can be powered by newer computers compatible
with the new VESA standard using pin 9 of the VGA connector as
the +5VDC source. An external power supply is also provided
for use with older computers, where power is unavailable
through the VGA connector or the available power is inadequate.
Features
• Powered by computer — This unit can be powered by most
newer computers.
• Power/Signal LED — Green LED = power + signal. Amber
LED = power but no signal. Off = no power.
• Gain/Peak DIP switch — To compensate for longer cable runs.
• Out Imp DIP switch — Changes the output impedance to be
compatible with all projectors.
• Cable retention chain — To prevent a lost or misplaced input
VGA cable, the cable can be secured to the unit (either model)
with the supplied chain (attached to the right standoff nut of
the input VGA connector).
