MS146 Manual 1
INTRODUCTION
The MS146 is a family of bar code slot readers specifically designed for
reading ID, membershop, or other types of cards that contain bar codes.
The MS146 comes in four interfaces: PS/2, RS232, USB, and TTL Wand.
The MS146 also comes in two different optical types: Visible Light
(660nm) for reading normal bar codes, and Infrared Light (930nm) for
reading bar codes hidden behind an opaque security film.

Normal Operation
MS146A and MS146IA
The Undecoded (or TTL, or Wand) MS146A requires an external decoder
in order to communicate with your computer. Decoders are built into
Wedge devices and many POS (Point of Sale) keyboards, such as the
Unitech KP3700.
The MS146A cannot be configured via Scanner Configuration Manager.
Any modification of the output data must be done in the external decoder.
MS146-2 and MS146I-2
The RS232 (Com Port) interface should only be used when your software
is designed to accept com port input. The MS146-2 has a built-in decoder
and outputs the scanned data in ASCII Code. MS146-2 input requires
special software such as HyperTerminal (Bits per second: 9600, Data bits:
8, Parity: None, Stop bits: 1, Flow control: None) in order to view the
output.
The MS146-2 will require an optional power supply unless your computer’s
com port supplies power (unlikely).
