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, Honeywell internal use
only.
12 LED
-
Negative connection for scan mode indicator.
An external pull-up and LED are suggested. Maximum
current is limited to 25 mA. This line is active low when
the scanner is in the scanner mode (
i.e
. scan line is
present).
* Pins 4, 5, 6 and 8 main function is to transmit scan codes between the
Keyboard Wedge and PC.
