IS4125-41 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 Function
1 VCC
Input. 5 VDC (± 0.25V)
This requires 25 mA in standby and 130 mA peak.
2 Ground Signal and power ground.
3 Receive
Input. RS232 receive data from host.
Nominal ±12V signals.
4
Light Pen
Source/DTR IN
Input. Either light pen source voltage (t5VDC) when
configured for wand emulation or RS232 Data Terminal
Ready signal from host. Nominal ±12V signals.
5 RTS
Output.
RS232 Ready to send signal from the scan engine.
6 Light Pen DATA
Output. Wand emulation data, open collector output from
the scan engine.
7 Transmit
Output. RS232 transmit data from the scan engine.
Nominal ±12V signals.
8 CTS
Input. RS232 Clear to send signal from host.
Nominal ±12V signals.
9*
Good Read
Indicator
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. ). It is recommended that the indicator
is terminated directly to ground.
10* Beeper -
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.
11 Reserved Input
Input. Do not connect to this pin. This pin is for Metrologic
internal use only.
12 LED -
Negative connection for LED. An external pull-up and LED
is suggested. Maximum current is limited to 25 mA. This line
is active low when the laser diode is active.
* Pins 9 and 10 can be used together to form a push-pull type circuit. Pin 9
becomes the and Good - Read source whereas Pin 10 supplies the
pathway to ground..
