Baud Rate
The default baud rate for communication between the personal
computer and the Processor is 9600 (19200 for M/N 57C435
Processor). The operating system for the Processor module(s), as
well as application tasks that are loaded using the /ALL option, will
be loaded at 9600 baud if there are no tasks currently running in the
rack.
You can change the baud rate by editing the Baud Rate parameter
on the Communication Setup screen. See section 5.5.3 for more
information. The allowable baud rates are 1200, 2400, 4800, 9600
and 19200 baud. You can override the baud rate settings at any time
through the BAUD RATE option available when you are online with
the Processor(s) (see 12.1).
Cable Connection
You will need to purchase cable M/N 61C127 or manufacture a serial
cable with a 9Ćpin connector on one end for the personal computer
and a 25Ćpin connector on the other end for the Processor module.
Use the cable to connect the serial port on the personal computer to
the upper connection, labeled PROGRAMMER/PORT B", on the
leftmost Processor module in the rack. See Appendix A for a
description of the pins and directions for making your own cable.
3.3.2 Using a PC Link Module
The AutoMax Programming Executive software supports the use of
the AutoMax PC Link Interface module (M/N 57C445) to
communicate with a rack over the AutoMax Network. The PC Link
module is functionally equivalent to a Network Communications
module, and allows the personal computer in which it is installed to
function as a drop on the AutoMax Network. By using AutoMax PC
Link modules, up to four PC workstations can communicate with a
single AutoMax rack.
Use the procedures described in the AutoMax PC Link Interface
Module instruction manual (J2Ć3011) to configure and install the PC
Link module in the personal computer, and to load the PC Link
software onto the personal computer's hard disk. Note that the PC
Link software (included with the PC Link module) must be
loaded in the same directory as the AutoMax Programming
Executive software. This will ensure that the PC Link module is
recognized by the Programming Executive.
Section 5.5.3 of this manual describes how to configure the
Programming Executive to use the PC Link module for online
communication.
3.4 Connecting the Personal Computer to an
AutoMax PC3000
Depending on the configuration of the AutoMax PC3000, you can
connect the personal computer:
D directly to the PC3000 via the ISA bus
D directly to port B of the PC3000 Serial card
D remotely to the PC3000 via the DCSĆNET network
D remotely to the PC3000 via modems
