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
