Power Supply (1)
DE does not have a built-in power supply. Instead it uses a plug-in type external
power supply (AC adapter). One reason for this feature is electrical safety. Keeping
danger voltages (main) out of the DE increases the electrical safety. Therefore an
external power supply of high quality and safety should be used. If DE is used in
Germany the external power supply has to be VDE approved. Another reason for the
external power supply is the fact that mains voltages and plug types vary
considerably from country to country. Using a plug-in external supply DE can be used
any where with a locally purchased power supply, thus keeping the retail price down.
The power supply has to be able to deliver 7-12 V unstabilized DC voltage, as well as
a minimum current of 100mA. DE is switched ON by plugging the AC adapter into a
wall outlet and connecting it to the appropriate jack on the DE board. There is no
separate on/off switch. If the polarity of the power supply is incorrect, DE will not
function. However, there is no danger of damage to the circuitry since it is protected
by a diode. The correct polarity is: outside ring = GND, inside lead = +7...12V. A
power supply for 230V mains voltage with European type mains plug is included with
the DE (valid only within Europe, for other countries ask you local Doepfer
representative or dealer).
Midi Out Socket (2)
Connect the Midi Out socket with Midi In of the device to be controlled by DE (e.g.
Computer, Synthesizer, second daisy-chained DE or another OEM/DIY product like
MKE, CTM64, Pocket Electronic) via a suitable Midi cable. If you want to control
more than one Midi device you have to use daisy chain Midi Thru / Midi In connection
of the devices ore use a external Midi Thru box.
Midi In Socket (3)
The DE features a Midi input. This input may be connected to another Midi device
(e.g. Midi keyboard). The incoming Midi data are merged to the data generated by
DE. The Midi input may be used as well for daisy-chaining several DE. The Midi input
of DE is not suitable for large amounts of Midi data (e.g. SysEx strings or Midi
messages coming from an computer sequencer) as the DE has only a small Midi in
buffer. In case of large amounts of incoming Midi data loss or delay of data may
occur.
The Midi input is also required when DE is programmed with the editor software. In
this case the Midi input of DE has to be connected to the Midi output of the computer
on which the editor program is running. The Midi output of DE has to be connected to
the Midi input of the computer. Details can be found in the Pocket Dial manual and
the manual of the editor program.
Even if DE is used to generate absolute Midi control change messages with data
update/feedback from the device controlled by DE the Midi In of DE has to be
connected to Midi Out of the device in question. Details about this mode are available
in the Pocket Dial user's manual.
If none of the applications described above is used the Midi input is left open.
