USING SERIAL COMMUNICATIONS

This section describes how to use the Serial Communications. Before you can apply

this section, the M–Traverse must be interfaced with a host computer through a RS422

Serial Communications Interface. The host computer must have the M-Host software

or its equivalent installed.

The M–Traverse comes factory pre-loaded with default Serial Communications Setup

Control Parameters. These Control Parameters set up the M–Traverse to

accommodate the RS422 Serial Communications Interface. Generally, the default

settings are suitable for most applications and do not require modification. The factory

default Serial Communications Setup Control Parameters are found in Appendix E.

When communications have been established through the host computer, these default

parameters can be modified, using the Serial Communications Interface.

CP-70 DEVICE ADDRESS

The M–Traverse has an access address which can be set from 1 to 32. Each individual

M–Traverse on a multidrop RS422 communications link needs a unique Device

Address. The address “00” will be globally accepted by all of the M–Series Controls on

the communications link, however, they will not send a response message back to the

host computer when this global address is used.

CP-71 BAUD RATE

There are six different baud rates (data rates) for the M–Traverse. Enter the number,

for the required rate, as listed below.

1 = 300 Baud

2 = 600 Baud

3 = 1200 Baud

4 = 2400 Baud

5 = 4800 Baud

6 = 9600 Baud

1 2 ... 106 107 108 109 110 111 112 113 114 115 116 ... 201 202
