Doepfer A-100 - Manual (Page 8)

Installing modules
•
To be on the safe side please calculate the total current requirement of existing
modules plus the new module/s.
• Check that this total is less than 1200 mA (or 2400 mA or 4800 mA depending
upon the A-100 case that is used). Normally this will apply.
• If that's OK: First of all, take the A-100’s plug out of the wall socket.
• Check if each module is equipped with a ribbon cable with a 16 pin female
connector at the open end. The ribbon cable can be 10 or 16 pin but the female
connector has to be 16 pin !
• Now join the free end of the ribbon cable to the nearest available position on the
system bus board
• For this one has to plug the female 16 pin connector at the free end of the ribbon
cable to one of the pin headers of the bus (these are also 16 pins). Use a pin
header of the bus board that is close to the position where the module has to be
mounted later.
• Check very carefully that it is connected so that the coloured marking on the
ribbon cable is at the bottom of the bus connector. The coloured marking has to
align with the "-12V" printing on the bus board next to the pin header.
• Check also very carefully that it is pushed fully home, not at a slight angle and
not vertically or horizontally displaced .
• Failure to check this may result in the module’s instant destruction as soon as the
power is turned back on!
• When you’re installing extra modules, it may be necessary to take another module
or two out, to allow you easier access to the bus board.
• Place the module carefully into the space in the rack, and fasten it firmly in place
with the supplied screws (M3x6).
• Repeat this procedure until all modules (and possibly blind panels) are installed
and the front of the A-100 case is fully closed.
• Now plug the system A-100 back into the main power supply, and switch it on.
• Test out the newly installed modules.
• If it doesn’t seem to be working as expected, immediately disconnect the system
from the power supply again.
• In this case, double-check all connections, making completely sure that the ribbon
cables are the right way round where they connect to the bus.
Interconnecting modules
For connecting modules to each other, you need mono mini-jack ( 3.5 mm) patch
leads. We offer patch leads in different lengths (from 15 cm to 2 m) and colors.
