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.
