Serration pulse switch — This DIP switch-selectable feature adds or strips the serration pulses from the signal to make it compatible with digital display devices. Use the serration pulse switch if flagging or bending occurs at the top of the video display. Gain/peaking adjustment — Output gain and peaking levels may be adjusted individually for red, green, and blue channels by using jumpers that are accessible inside the enclosure. Sync polarity adjustment — Horizontal and vertical sync out

5 Video input termination toggle switch (RGB 500 AKM only) — The toggle switch on the front panel allows you to select video input impedance. Set the toggle switch to the top position for high Z when a local monitor is connected, or set it to the bottom position for 75 ohm impedance when no local monitor is connected. 6 DIP switch access cover and DIP switches — Use a screwdriver to remove the cover to gain access to the DIP switches.

Installation Overview To install the interface, follow these basic steps: Set the DIP switches, located inside the access panel (see page 2-3), and the 1 gain/peaking adjustment jumpers, located inside the enclosure. (See below.) Set the front panel video termination toggle switch on the RGB 500 AKM, or 2 set the front panel ID bit DIP switches on the RGB 560 AKM. (See page 2-4.) Connect the signal output and power cables. (See “Attaching output 3 cables” on page 2-6.) 4 Temporarily connect t

Installation and Operation, cont’d 3. If the image appears, but it looks scrambled or cuts in and out, check the DIP switch settings. If all switches are already set to what should be the correct settings for the connected input and output devices, try different settings. If the display device is digital (including LCD, DLP, and plasma devices), try changing the vertical sync pulse width (see page 2-4). Next, try changing the sync options (sync on green, composite sync output), sync polarity, o
