User Interface overview
Flyer’s DB-25 User Interface connection provides an isolated +15 VDC, 400 mA internal supply for power-
ing externally-connected I/O devices; two high-speed optoisolated inputs; six bipolar optoisolated inputs;
and eight bipolar optoisolated outputs that allow you to automate your marking operation. The male DB-
25 User Interface connection requires a matching DB-25 female connector in order to attach external I/O
devices to Flyer. A female DB-25 connector is included in the Flyer ship kit for this purpose.
Caution
possible
equipment
damage
The pin assignments on Flyer’s DB-25 User Interface connection
are NOT compatible with FH Smart’s DB-25 Parts Handling Control
connection. If you are integrating an FH Flyer head into an exist-
ing FH Smart marking system, you must revise any I/O eld wiring
connected to Flyer’s DB-25 connection. Failure to do so may damage
Flyer’s internal circuitry and/or any external devices connected to the
I/O wiring harness.
A simple parts handling system utilizing FH Flyer I/O to control marking might operate like this: A con-
veyor stops with a new part positioned under the marking head and then delivers a ‘start mark’ signal to
