1.  INTRODUCTION

Welcome to use the ARLACON MC family of control products. Like other ARLACON control
systems the MC300 combines simple and compact system structure with powerful system
software and programming tools.

The MC300 features continuous path servo control for up to 8 axes, expandable i/o
connections and RS-232/422 communications. Additionally, MC300 combines a user terminal
with an lcd graphics/text display and a function keypad in the same control unit.

This manual contains information on installing and using the MC300 control system. Please
study the following chapters carefully before starting to work with your system. Also refer to the
ARLACON McWay I/O system user’s manual and the McBasic programming environment
reference manual where applicable.

In case you have questions or suggestions concerning this manual, the MC300 or other
ARLACON products, please contact your ARLACON dealer or the manufacturer:

1.1  GENERAL

The MC300 control unit combines a programmable control computer with a 320x240 pixel
backlit graphical/text lcd display and a 24key function keypad with programmable led indicator
lamps.

The MC300 is equipped with two serial interfaces that can be used for communications or
networking, a connection for standard ASCII keyboard and a McWay connection for the i/o
system.

To get the MC300 operating you only need a 24Vdc power supply and a terminal or a PC for
programming.

The MC300 can also be configured as a "Dumb terminal" for use as user interface terminals
for ARLACON control systems or other systems using RS-232, RS-422 or optical fibre
communications.

1.2  MC300 FLUSH MOUNT CONTROL UNIT

The MC300 flush mount version is designed for mounting on cabinet doors and instrument
desks where it provides flexible user interface capabilities for all types of application.

It is available with either RS232 and optical fibre connections or RS232/RS422 connections.
