Technical Issue: Wiring a Footswitch to an FH Flyer Marking Head or a Fenix
Flyer Laser Marker
Date:
27 August 2008
Description:
This Technical Bulletin describes how to connect a customer-supplied footswitch to trigger semiautomated marking using an FH Flyer marking head or a Fenix Flyer Laser Marker.
This Bulletin covers the following topics:
•
Introduction
•
Wiring the footswitch
•
Adding automation to the mark file
Introduction
In many semi-automated marking applications, the machine operator will depress a footswitch to
trigger laser marking. This Technical Bulletin describes the wiring required to incorporate a
customer-supplied, manually-operated footswitch and modify WinMark Pro mark files with the
required input automation sequences.
Wiring the footswitch
To connect a manually-operated footswitch to an FH Flyer marking head, refer to Figure 1 and
perform the following steps:

Important Note:
1
Figure 1 is drawn looking at the rear (solder-cup side) of the female DB-25
connector.
Locate the female DB-25 connector included in the marker’s Ship Kit and connect Pin 1 (+15
VDC) to one side of your single-pole/single-throw (SPST) footswitch.
Note:
If using a single-pole/double-throw (SPDT) footswitch, connect Pin 1 to the center, or
Common, terminal.
2
Connect the Normally Open (NO) footswitch terminal to Pin 20 (IN0_A).
3
Connect Pin 8 (IN0_B) to Pin 14 (15V RTN).
Adding automation to the mark file
Perform the following steps to add the required automation sequence to your mark file:
1
Open your mark file in WinMark Pro’s Drawing Editor and select the Drawing object by
clicking a blank section of the Drawing Canvas.
2
Select the Automation tab and click Wait Digital Before Piece.
3
Click the arrow button and then click IN0.
4
Click the arrow button and choose Set. The Automation tab should appear as shown in
Figure 2.
After a mark session is opened, this automation step forces WinMark Pro to wait indefinitely
until a voltage is applied to input IN0. This is called the ‘start mark’ signal.

5
Click Wait Digital After Piece.
6
Click the arrow button and then click IN0.
7
Click the arrow button and choose Clear. The Automation tab should appear as shown in
Figure 3.
Step 7 forces WinMark Pro to wait indefinitely until voltage is removed from input IN0. This
ensures that only one mark is lased each time the footswitch is depressed AND prevents
continuous marking from occurring if the footswitch fails in a closed position.

8
Click the Marking tab and set the Mark Count property to zero (0).
After beginning a mark session where Mark Count equals 0, an automated mark session
continues indefinitely. WinMark waits for a ‘start mark’ signal on input IN0, lases the mark file,
verifies the ‘start mark’ signal has cleared, and then loops back to repeat the process. To end
an automated mark session, press ESC on the computer keyboard.
9
Repeat this procedure for each mark file used with the footswitch.
