This chapter describes how to use the Config. Output feature of the
USER–PAK option to create custom serial port messages, including how to:
•
Select and define a serial port
•
Define serial port strings
•
Connect and configure the CVIM serial port for communication
This section introduces custom serial port messages, by posing some
questions, and answering them.
What are custom serial port messages?
For communication between the CVIM module and a remote device, the
CVIM module has a serial port (CVIM module series A has one serial port,
series B or later, two serial ports). With the USER–PAK option installed,
you can create your own custom serial port messages for transmission
through the serial port. The messages consist of ASCII characters.
What types of information can be sent?
Within each message you can send literal text, results and other data on
specific tools, statistical data, and other information.
How do you create custom serial port messages?
You create serial port messages using the
Config. Output feature, which is
part of the Env. menu (when the USER–PAK option is installed).
The format of a message is defined by a “string.” The string consists of text
which specifies the format and content of the message, the condition under
which the message is transmitted, and repetition parameters, which can be
used to transmit the message multiple times for the same condition.
How do you determine when a custom serial port message is sent?
When defining a message string, you select the “event” which causes the
string to be sent. The string can be sent after each inspection, or only upon
certain conditions, such as the failure of a specific tool, for instance.
