Parts of the Scanner
1 Green and Red LEDs When the green LED is on, this
indicates that the unit is receiving
power and the laser is on. When the
red LED flashes on, the scanner has
read a bar code successfully. When the
red light turns off, communica-tion to
the host is complete.
2 Speaker The speaker emits a beep when a bar
code has been decoded.
3 Laser Output Window This aperture emits the laser light.
4 Mil spec Connector The 19-pin male Mil spec connector
was designed to connect a communi
cation cable from the scanner to a host
device. The communication cable may
include a power supply or it may be de
signed to draw power directly from the
host device. The standard TECH 7 has
one connector. (When atrium option is
installed, a second connector is
installed on the unit to connect the
MX001 Industrial Control Interface
box.)
