display.
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.
Operation
After the P/2 DA2 Plus and its connected devices are powered up, the system is fully
operational. For further information, see “Troubleshooting” below.
Troubleshooting
Check all cable connections. If problems still exist, check the following steps:
1. If the image on the laptop and/or projector is distorted or unstable, do the following:
• Check if the front LED of the P/2 DA2 Plus is lit.
• Slide DIP switch 1 to a different position to see if the image becomes normal.
2. If there is no image on the projector, do the following:
• Check if the front LED is lit.
• Check if the VGA signal from the laptop is routed to the VGA port. Each laptop uses a
different key combination for this function.
• Slide DIP switch 2 to a different position and see if an image appears.
3. If the image still does not display correctly or the front panel LED of the P/2 DA2 Plus does
not light, call the Extron Sales and Support hotline.
