Installation and Operation, cont’d

Operation

After the distribution amplifier and its connected devices are powered up, the system is fully operational. If any problems occur, ensure that the cables are properly routed and connected.

Sync impedance switches

To solve laptop compatibility issues on the video input, or reflection problems on the video output, use these dip switches to correct for sync impedance mismatches.

Switch 1 (sync input impedance) — The default setting is OFF (510 ohms). If the image from the laptop is unstable, slide the DIP switch ON (10k ohms).

Switches 2-7 (sync output impedance) — Each of these switches controls a pair of outputs simultaneously (see table below). The default setting is OFF (50 ohms). If the front LED is green and all the input and output cables are connected correctly, but there is no image on the display, slide the switch to ON (75 ohms).
