SCANNER TERMINATIONS
IS4110 Connector Pin Assignments
Metrologic provides a low profile ZIF 10-pin connector
that accepts an FPC/FFC cable with a 1.0 mm Pitch
and a 0.3 mm end thickness. This cable is available
from Metrologic in various lengths.
The pin assignments are as follows:
Pin Signal Name Function
1 VCC
+5V +/-.25V supplied from terminal
(100 mA minimum supply)
2 Data Out
Open collector output. A black bar is indicated by a low
signal. A 5K ohm pull-up resistor is recommended.
3 Range Select
Open collector input. A low on this line will put the scanner
in long range (9” – 13”) activation mode. This line may be
left unterminated for short range (4” – 7”) activation mode.
4 Scan Sense
TTL output. The signal pulses high once for each scan
cycle (i.e. one scan in each direction). There are 35 scan
pulses per second.
5
Scan Mode
Indicator
Open collector active low output. This pin will go low
whenever the scan mode is activated. It is capable of
sinking 15 mA and can be used to activate an indicator
light.
6 IR Enable Do not connect to this pin.
7 Ground Power ground
8 Object Detect
TTL output. A low signal indicates an object is within the
scan field. The signal remains low until the object is
removed.
9* Scan Enable
TTL low input. A low signal applied to this pin will activate
the scan mode. High or open deactivates the scan mode.*
10* Scan Enable
TTL high input. A high signal applied to this pin will activate
the scan mode. Low or open deactivates the scan mode.*
* Use either pin 9 or pin 10 to activate the scan engine.
