P/2 DA2xi.
• Connect the display device to the Output 15-pin HD connector of the P/2 DA2xi.
Step 4 — Set DIP switches
Set DIP switches 1 and 2 for input and output impedance and set DIP switch 3 for
gain/peaking:
Switch1(syncinputimpedance) – Default setting is down
(510 ohms). If the image from a laptop computer becomes unstable, slide the switch
up (10k ohms).
Switch2(syncoutputimpedance) – Default setting is up (50 ohms). If the front LED
is green and all the input and output cables are properly connected, but there is no
image at the projector, slide the switch down (75 ohms).
Switch3(videogain/peaking) – Slide the switch down (off) if the output cable
length is under 100 feet (30 m). Slide the switch up (on) if the output cable length is
over 100 feet (30 m).

Step 5 — Power up
Connect the power supply cord of the P/2 DA2 Plus to a 100 to 240 VAC power source and
power up the local monitor, PC, and display device.
CAlways use a power supply specified by Extron for the
P/2 DA2xi. Use of an unauthorized power supply voids all
regulatory compliance certification and may cause damage to the
power supply and the P/2 DA2xi.

Operation
After the P/2 DA2xi and its connected devices are powered up, the system is fully operational.
If any problems are encountered, verify that the cables are routed and connected properly.
