Overview
Introducing the MS839
As a keyboard scanner supports most of the popular PCs and IBM terminals.
As a RS232 serial scanner sends data by using RS232 communication protocol.
The communication speed (baud rate) ranges from 300 bps to 38400bps.
As a RS232 terminal interface, systems with ANSI ASCII communication
environment such as UNIX, XENIX are installed between a host computer and
a terminal and supports full duplex and block communication modes.
As a wand emulation scanner, the output of the scanner emulates a wand
scanner output. Two output formats are supported. Code 39 format and Native
Code 39 format, the scanner always outputs the same data contents but with
Code 39 what symbology. Native scanner the same contents and symbology
as the scanned label.
The scanner supports the following bar code symbologies:
Code 39 Standard and Full ASCII Codahar
UPC/EA.N with supplement codes UCC/EAN128
Interleaved 2 of 5 Code 32 (Italian pharmacy)
Standard 2 of 5 Code 93
MSI code Code 128
Plessey code China Postal Code
(Toshiba Code)

As a keyboard Interface, the scanner is actually installed between a PC (or
terminal) and a keyboard. See Figure for reference. The scanner sends data to
the host device by emulating the keyboard input and acts like an extension of
the keyboard.

This scanner can be installed easily by following the installation guide
illustrated below. Before you start the installation, locate a "Y" type cable in the
package.
Installation procedures:
1) Plug the modular (RJ45) connector of the "Y" cable into the bottom of the
scanner until you hear a click sound.
