AdaptaScan Reader to a PLC-5
Using RS-232/ASCII Protocol with
the 2760–RB Module
and the 2760-SFC1 and -SFC2
Protocol Cartridge
The AdaptaScan-SN3, -SN5 or -SN8 bar code reader may be
configured to communicate with the 2760-RB interface module via
“dumb terminal protocol” RS-232, using the 2760-SFC1 or -SFC2
protocol cartridge.
This document includes cable diagrams and configuration
information for the AdaptaScan readers. It also includes an example
PLC-5 program which is needed to establish communication from
the PLC to the 2760-RB.
The following Allen-Bradley hardware is needed to use the
procedure described in this application note:
2755-SN3, -SN5, or -SN8 AdaptaScan reader and related
manuals.
2760-RB interface module in a 1771 rack with a PLC-5
processor
2760-SFC1 or –SFC2 protocol cartridge
Personal computer or VT 100 type terminal to configure the
2760-RB
Appropriate cables to program the PLC-5 and to configure the
2760-RB interface module and the AdaptaScan reader. Refer to
hardware manuals for cable requirements.
Catalog Number 1784-KT or equivalent card installed in the
computer to enable you to program the PLC-5.
