In this manual, Remote Interface refers t o the three communication
interfaces that the controller can use to communicate with a computer or a
terminal via commands i n ASCII format. I t is n o t called a Computer
Interface since any device capable of sending ASCII characters can be
interfaced with the controller.
The Remote Interface should not be confused with the analog and digital
I/Os. These interfaces communicate with the controller via discrete lines,
with specific functions, without using any motion commands. They are
used to synchronize external events in complex motion systems.
Selecting the interface
The MM4006 controller is equipped with RS-232-C, RS-485 o r IEEE-488
interface. Selecting the interface and setting the parameters is done
through the General SETUP menu on the front panel.
For more details on setting up communication parameters see the
Controller Configuration paragraph of the Local Mode chapter.
3.1.1 R S -232-C Interface
Hardware configuration
The serial (RS-232-C) communication p o r t is a 9-pin D-Sub connector
located on the rear panel. The pinout is designed to interface directly with
an IBM PC or compatible computer, using a one-to-one cable. No special
adapters are required.
Appendix C shows the pinout of the RS-232-C connector and different cable
types that may be used to interface to a computer.
Communication protocol
The RS-232-C interface must be properly configured o n both devices
communicating. A correct setting is one that matches all parameters (baud
rate, number of data bits, number of stop bits, parity type and handshake
type) for both devices.
RS-232-C communication parameters are set through the General SETUP
menu on the front panel. To make changes, follow the instructions in the
Controller Configuration paragraph of the Local Mode chapter.
