2-5 RGB 500 AKM and RGB 560 AKM Installation and Operation
Installation Overview
To install the interface, follow these basic steps:
1 Set the DIP switches, located inside the access panel (see page 2-3), and the
gain/peaking adjustment jumpers, located inside the enclosure. (See below.)
2 Set the front panel video termination toggle switch on the RGB 500 AKM, or
set the front panel ID bit DIP switches on the RGB 560 AKM. (See page 2-4.)
3 Connect the signal output and power cables. (See “Attaching output
cables” on page 2-6.)
4 Temporarily connect the computer video and audio input cables and (for
the RGB 560 AKM) the local monitor output cable. (See “Connecting input
cables” on page 2-7.)
5 Connect power cables to the input and output devices. Turn on the input and
output devices.
6 The image should now appear on screen. If it does not appear, or if the
picture is displayed incorrectly, double check and make adjustments to cables,
DIP switches, and jumpers as needed. (See “Pre-installation testing/
troubleshooting” on page 2-7.)
7 Temporarily disconnect the computer video cables and the audio input cables
and (for RGB 560 AKM) the local monitor output cable from the front panel
of the interface.
8 Install the interface in the Ackermann floor tank.
9 Reconnect the computer video and the audio input cables and (for
RGB 560 AKM) the local monitor output cable to the interface, and readjust
horizontal centering as needed via the front panel knob.
Installation and Operation Instructions
Adjusting the gain/peaking jumpers
Video signals passing through long cable runs (over 125 feet) can decrease in
strength, creating signal loss. The longer the cable, the higher the video level and
the greater the peaking that will be needed to compensate for the loss.
To change the gain/peaking jumpers, do the following:
Disconnect power before making these adjustments.
1. Remove the faceplate from the enclosure by removing the four screws
shown in figure 4, and loosen the two screws shown. Do not pull the
output cables out of the enclosure.
