Setup Guide — RGB 560 AKM

The Extron RGB 560 AKM Architectural Interface is an analog, computer video and audio

interface with 300 MHz video bandwidth. It installs in an Ackermann ﬂoorbox. This guide

provides basic instructions for setting up the RGB 560 AKM.

Step 1 — Set the DIP switches behind the access cover

a. Using a small Philips screwdriver, remove one screw to take off

the access cover.

b. Set DIP switches 1 through 8 to On (up) or Off (down) as desired.

1 — Sync on green 2 — DDSP (up) or ADSP (down [default])

3 — Serration pulse 4 — Composite sync output

5 — Force negative horizontal and 6 — Vertical sync pulse width

vertical sync polarity

7 and 8 — Composite sync routing for Macintosh monitors:

• For Macintosh 13": Set 7 to Off (down) and 8 to On (up).

• For all other Macintosh: Set 7 to On (up) and 8 to Off (down).

No other combinations are valid.

c. Replace the access cover.

Step 2 — Set the gaining and peaking adjustment jumpers

If using cable runs over 125 feet (38 m) you may need to adjust the gain and peaking jumpers

(located inside the unit) to compensate for signal loss, as follows:

a. Disconnect power

from the RGB 560.

b. Remove six front

panel screws and take

off the faceplate. Do

not pull the output

cables out of the

enclosure.

c. Use needlenose pliers

to move gain/peaking

jumpers J16 (blue), J17

(red), and J18 (green).

Place the jumpers on

the pins that yield the

best image display:

• Pins 3 and 4: Increase the output signal and add 50% of the maximum peaking.

• Pins 2 and 3: Provide unity output (0.7 volts with no peaking [default]).

• Pins 1 and 2: Increase the output signal and add 100% of the maximum peaking (for very

long cable runs).

d. Reattach the faceplate and replace the screws removed in step 2b.
