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.
