MULTI-INTERFACE UNIT
The DEK Multi-Interface Unit (MIU) is a communications interface that allows
DEK Printing Machines to communicate with upline and downline board han-
dlers.
The MIU stores 6 preprogrammed protocols for communications with the most
common manufacturers of board handlers. Provision has been made for
extending the list of available types to 16.
The upline and downline protocols are selected using the Protocol Selection
switches on the MIU, Protocol Selection section refers. The upline and down-
line selectors are independent of each other allowing the upline and downline
machines to be of different protocols.
Power supplies of +24V and +12V power the communications devices of the
associated upline and downline handlers. Input signals to the unit are opto-
isolated. Relay or open collector output driver signals are available for the MIU
outputs.
Internal links are provided between the upline connector (M1SK1) and the
downline connector (M1SK2) which may be used if communication is required
to by-pass the DEK machine.

Power Supplies The MIU is mounted behind the front panel of the machine and receives its
power supplies via the machine controller enclosure. Derived supplies are
made available for the upline and downline interfacing (0V is common).
The power supplies are fused on board with self resetting poly fuses.
NOTE
+24V (Switched) is removed when the machine E Stop is pressed.
