RGB 500 AKM and RGB 560 AKM Installation and Operation 2-4
6 — Vertical sync pulse width
For some digital display devices, if no picture appears, the picture cuts
in and out, or the picture is scrambled, you may need to select the wide
vertical sync pulse width.
ON — When this switch is set to On, narrow sync pulse width is
selected.
OFF — When this switch is set to Off, wide sync pulse width is
selected. (Default setting.)
7 & 8 — Composite sync routing
These are used for routing local monitor signals for Macintosh 13”
monitors and all other Mac/VGA-type monitors.
7 = OFF and
8 = ON — For Macintosh 13” monitors, set DIP switch 7 to Off and 8
to On for proper sync routing for the 15-pin HD local monitor
output. This is used with Macintosh cable adapter kits
#70-078-01 and #70-078-02, which include audio connections.
7 = ON and
8 = OFF — For all other Macintosh and VGA-type computers, set DIP
switch 7 to On and 8 to Off to pass the signal from input pin 9
through to pin 9 of the local monitor output. (Default setting.)
7 = ON and 8 = ON or
7 = OFF and 8 = OFF — These settings are not valid combinations.
They will not work with either computer type.
7 Audio input connector — Use this 3.5 mm stereo jack to connect an audio
source to the interface.
8 Computer video input 9-pin D male connector (RGB 500 AKM only)
9 Computer video input 15-pin HD female connector
(RGB 560 AKM only)
10 Front panel DIP switches (RGB 560 AKM only):
ID PIN 4 (pin 4 local monitor ID bit termination)
ID PIN 11 (pin 11 local monitor ID bit termination)
Use these DIP switches to provide proper ID bit termination if a local
monitor is not connected to the interface’s buffered local monitor
output.
ON — Set both switches (ID PIN 4 and ID PIN 11) to On if no local
monitor is connected. Pins 4 and 11 are grounded for ID bit
termination at the 15-pin HD local monitor output.
OFF — Set both switches to Off if a local monitor is attached to the
interface. No monitor ID bit will be set. (Default setting.)
11 Buffered local monitor output 15-pin HD female connector (RGB 560
AKM only)
