Connecting the Scanner

Publication 2755-6.4

Overview

The scanner may be connected to a variety of host devices through a
synapse cable.  The communication parameters for the cables are
configured by scanning bar codes.  The three types of cables are:

•

RS-232 Synapse cable

•

Keyboard Wedge Synapse cable

•

Scanner Emulator Synapse cable

All configuration bar codes are in the Programming Guide for 2-D
Bar Code Scanners.
