DOEPFER MUSIKELEKTRONIK A-100 Bedienungshinweise Seite 6

(1) Power Supply Socket
This is the socket to which the plug from the external power supply is connected (12-15V
AC, min. 400mA)
(2) Bus connectors
These are the pin headers which are used to connect the A-100 modules. Up to five
modules can be connected:
•
Please calculate the total current requirement of the modules that have to be
installed into the A-100MC (or driven by the A-100MBP). Check that this total is less
than 200 mA. Otherwise the A-100MBP or A-100MC is not suitable.
•
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 !
•
Remove the external power supply from socket (1).
•
Remove and install modules only with the AC/AC adapter disconnected from
the A-100MBP !
•
Now join the free end of the ribbon cable to the nearest available position on the bus
board
•
Check also very carefully that the connector is pushed fully home, not at a slight
angle and not vertically or horizontally displaced.
• In the version 4 of the A-100MBP boxed pin headers are used which are equipped
with a reverse protection (gap for the "nose" of the socket of the bus cable). When
the bus cable coming from the module is connected to the boxed header in question
the "nose" has to point to the right. The polarity of the cable is correct if the red wire
of the bus cable then points to the bottom (to the continuous line labeled "RED
STRIPE" on the pc board). If this is not the case please do not connect the module
to the bus board ! Otherwise both the module and the power supply may be
damaged ! In that case please contact the manufacturer of the module and ask for
a suitable bus cable with the correct polarity of the connector.
• The bus cables of original A-100 modules manufactured by Doepfer are equipped
with suitable bus cables since 2012. Only for older A-100 modules manufactured
before 2012 it may happen that the polarity of the 16 pin female connector of the
bus cable is wrong (nose points to the left when red wire points to the bottom). This
is because in the past unboxed pin headers were used and the position of the
"nose" did not matter. In such a case please contact Doepfer or one of their dealers
and order a suitable bus cable.
