Doepfer MTC64 Power Board - Manual (Page 4)

Connections
JP1 (10 pin connector)
This pin header is connected to JP5 on the MTC64 main board and carries GND and
+5V (i.e. power supply). For the connection a 10 pin ribbon cable with a female
connector on each side is used. If two or more MTC power boards are used in
combination with one MTC64 main board this connection has to be carried out
parallel (i.e. GND and +5V for all boards). For this a special 10 pin ribbon cable has
to be used with the corresponding number of female connectors. A cable with 3
connectors is required for 2 power boards, a cable with 4 connectors is required for 3
power boards and a cable with 5 connectors is required for 4 power boards. If several
MTC power boards are ordered together a suitable cable is enclosed. If the power
boards are ordered one after another the special cable has to be ordered in addition
(please specify the number of female connectors and the distances between the
connectors).
Pay attention to the correct polarity of the connection: the wire of the ribbon cable
that leads +5V (this side of the connector is labelled "+5V" on the MTC64 main
board) has to direct to the mains connector (X17) on the MTC power board in
Richtung des Netzanschlusses (X17). If the cable is connected in the wrong way
GND and +5V are shortened. This may destroy the power supply !
JP2 (16 pin connector)
This pin header is connected to one of the pin headers JP1 (range 1...16), JP2
(range 17...32), JP3 (range 33...48) or JP4 (range 49...64) on the MTC64 main board.
For the connection a 16 pin ribbon cable with a female connector on each side is
used. Up to four MTC power boards can be combined with one MTC64 main board.
Connecting the cable in the wrong to JP1...JP4 on the MTC64 main board will cause
no damage. Only the sequence of the outputs will be mixed up.
X1 ... X16 (2 pin screw terminals)
These are the terminals for the loads (e.g. lamps, motors). Each 2 pin terminal
corresponds to one load. It is recommended to use standard mains connectors
between the outputs of the MTC power power and the loads. The connectors have to
be specified for at least 230V~/2A (resp. 115V~/2A in 115V applications).
X17 (2 pin screw terminal)
This is the mains connector. This terminal is used to establish the connection to the
115/230V mains. For the connection an additional fuse (max. 16A) has to be used. In
case of a partial version (e.g. 8 or 4 stages only) a smaller fuse has to be used
suitable to the maximum current of all loads. Even for the mains a suitable connector
and possibly a mains switch can be used. All components have to be specified for at
least 230V~/16A (resp. 115V~/16A in 115V applications).
