FOREIGN MACHINE INTERFACE
Introduction The Foreign Machine Interface (FMI) is an electrical means of communication
between the machine and an adjacent machine, using electrical signals. The
signals are transferred using opto-couplers and/or relay contacts which keep the
machines electrically isolated.
The adjacent machine can be upline or downline of this machine in a left-to-right
or right-to-left board transfer arrangement, or it can be at one side of this
machine in a left-to-left or right-to-right arrangement.
The machine can interface with many different types of adjacent machinery
which can be of any proprietary manufacture. The adjacent machine utilizes a
set of timing and control signals (protocols) for communication with other
machines. As there are many different protocols, DEK supplies a custom
designed FMI to suit the protocol for each type of adjacent machine.
The FMI hardware comprises:
• An FMI Pod and connecting cable for the SMEMA interface only.
• A Multi-Interface Unit (MIU) for all other interfaces.
• An FMI loom which connects the FMI port, on the machine controller, to
the MIU or FMI Pod.
• Two interface cables, one cable for each adjacent machine.

FMI Pod The FMI Pod is only used where both the upline and downline is using a
SMEMA interface. For all other interfaces refer to the MIU interface later in
this chapter.
The DEK FMI Pod is a communications interface that allows DEK Printing
Machines to communicate with upline and downline board handlers.

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.
It simplifies the set up of the communications link between machines of different
manufacture by providing preprogrammed and programmable connections to
suit the interface protocol types commonly found within the board processing
industry.
The onboard, switch selectable, interface types are detailed later in this section.
Up to 16 interfaces can be specified for upline and downline handlers. The
upline machine can be of a different interface type to the downline machine.
Power supplies of +24V, +12V, +5V and 0V power the communications devices
of the upline and downline machines. Input signals to the MIU are opto-isolated.
Relay or open collector output driver signals are available for the MIU outputs.
A patching area routes patching link connections direct from upline to downline
as specified by any given protocol requirement.
The RS232 link is used for carrying out self tests on the MIU only and has no
function on the machine.
