IS4125-38 Connector Pin Assignments

Metrologic provides a low profile ZIF 12-pin
connector to connect to a 1 mm x 12 position
FFC/FPC cable. The pin assignments are as follows:
Pin Signal Name
1 VCC
2 Ground
3 Receive
4 DTR
5 D-
6 D+
7 Transmit
8 +USB_V
Good Read
9*
Indicator
10* Beeper -
11 Reserved Input
12 LED -
* Pins 9 and 10 can be used together to form a push-pull type circuit. Pin 9
becomes the Beeper + and Good - Read source whereas Pin 10 supplies the
pathway to ground.

Function
Input. 5 VDC (± 0.25V)
This requires 25 mA in standby and 130 mA peak.
Signal and power ground.
Input. RS232 receive data from host.
Nominal ±12V signals.
Data terminal ready signal from host.
Nominal ±12V signals.
USB D- Data Line
USB D+ Data Line
Output. RS232 transmit data from the scan engine.
Nominal ±12V signals.
+USB power from terminal defined per USB specification
Output. 5V high with a 2 kHz pulse. This drain is the pin
of a PFET type transistor that can source approximately
100 mA of current. This output is the connection for an
LED or other indicator (i.e. beeper+). It is recommended
that the indicator is terminated directly to ground.
Input. Collector of an NPN transistor that can sink
approximately 100 mA of current. A current limiting pull-
up resistor and Piezo type transducer (QMB- 111PXN or
equivalent) is recommended.
Input. Do not connect to this pin, for Metrologic internal
use only.
Negative connection for LED. An external pull-up and
LED are suggested. Maximum current is limited to
25 mA. This line is active low when the laser diode is
active.
