2–5 Initial Setup
Publication 2706–816
From time to time messages appear on the display that are not
generated by the application. They:
•
provide terminal status information during an operation
•
indicate minor faults, errors or numeric/ASCII entry mistakes
•
prompt operator to perform or not perform an action
•
notify operator of an error that prevents further operations.
To download applications to the MessageView 421 terminals, refer
to the MessageBuilder Configuration Software User Manual
(Publication No. 2706-817).
To upgrade the firmware in your terminal, see the procedure in the
MessageBuilder Configuration Software User Manual (Catalog
Number 2706-817).
Note: The MessageView terminal shares its RS-232 port between
communications with a computer that has MessageBuilder software
installed, and communications with an Auxiliary Device. The
terminal’s RS-232 port must be switched (configured) to the proper
setting before communications can be established. See Page 3–3 for
instructions on switching the RS-232 port between MessageBuilder
communication parameters and the auxiliary device communication
parameters.
