data input devices
devices used to enter data through the  MicroBar NX to the host system:
• 
pen barcode readers
• 
laser/CCD barcode readers in wand/laser emulation
• 
undecoded magstripe readers
• 
RS-232 input devices—electronic scales, barcode readers,
magstripe readers, . . .
dual RS-232 C
MicroBar NX connected between two systems communicating through
an RS-232 link (external power supply usually required)
external power supply
5V mains power supply adapter—necessary if the host system does
not provide enough electrical power to drive the  MicroBar NX
interface number
automatically configures the output data transmission parameters for
the host system your MicroBar NX is connected to
keyboard wedge
MicroBar NX connected between a keyboard and the host system—
data from the MicroBar NX is transmitted in keyboard emulation mode
to provide instant software compatibility (external power supply usually
required)
MicroBar NX
decoder and interface unit used to connect one or more data input
devices to a data processing host system—keyboard emulation for PCs
and terminals, RS-232 communication, . . .
operating parameters
parameters that affect the way the MicroBar NX operates—general
operating parameters include beep/LED settings, operating mode
settings, etc.
output transmission
parameters
host-system interface-specific communication parameters—in certain
cases they need to be modified to optimize the performance of the
MicroBar NX
symbology
barcode type or "family"—Code 39, UPC and EAN are examples of
common symbologies
