CHAPTER 7 FOREIGN MACHINE INTERFACE
INTRODUCTION
The Foreign Machine Interface (FMI) is an electrical means of communication
between the ELA machine and an adjacent machine, using electrical signals.
The signals are transferred using opto-couplers and relay contacts which keep
the machines electrically isolated.
The adjacent machine can be upline or downline of the ELA machine in a left-
to-right or right-to-left board transfer arrangement, or it can be at one side of the
ELA machine in a left-to-left or right-to-right arrangement.
The ELA machine can interface with many different types of adjacent machine
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:
• A Multi-Interface Unit (MIU) located on the rear of the machine.
• FMI loom connecting the FMI port, on the machine controller, to the MIU.
• Two interface cables, one cable for each adjacent machine.

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 ELA machine.
