IS4215 Pin Assignments
The IS4215 scanner terminates with a 25-pin male D-type connector. The pin
numbers impress on the connector:
Pin
Signal Name
Function
7
Ground
A power ground that can handle a 500-
milliampere load.
13
Laser/
A +5 VDC input to the head. Its use is to
Motor Control
start the flipper motor and signal processor,
and enable the visible laser diode (VLD).
This can be a TTL level signal and require
less than 1 milliampere of current.
18
No Connect
19
Power
Primary laser diode/motor power input. +5
VDC should be present at this pin and it can
supply up to 125 mA when enabled by the
signal at pin 6.
20
No Connect
23
Proximity Detect
The proximity detect is a grounding switch that
is active while an object is in the specified
detection field. The controlling computer should
provide a +5 VDC pull up. Ground the +5 VDC
pull up when the proximity detect activates.
This shows that an object has moved within
scanning range. We recommend that this
signal debounce for approximately 30 milli-
seconds.
Note
:
We did not make the design of this scan
head to have the continual enabling of the
laser as if the scanner is in a perm-anent
mounting fixture.
