Defining Strings for Serial Ports and Viewports

Pick the Ret key when finished entering or modifying text, which enters
the string into memory.
String Syntax: When you pick the Ret key, the CVIM module checks for
syntax errors; one of two messages is displayed beneath the string text –
String syntax message
String text entry, as it is
displayed on the keyboard
Cursor
String Syntax OK – the syntax of the string text is okay, and the string will
be transmitted (or displayed) as coded.
Syntax error at cursor pos. – If this message appears, the string text has at
least one syntax error – that is, one or more elements has not been entered
correctly. A syntax error will prevent the affected string element, and the
remainder of the string, from being transmitted (displayed). Check the string
text on the keyboard display; the cursor will be located at the point of the
first syntax error. Refer to the section “Valid Elements of String Text” to
check your string, and make corrections as necessary.
String Length: You can enter up to 40 characters in the string text.
Spacing: For readability, one or more spaces can be placed between
elements in the string text. Otherwise, spaces are not required unless
specifically called for in the format of an element.
Viewport string display: After entering text and picking the Ret key, the
string is displayed on–screen in the viewport (if the syntax is correct).
Viewport string colors: During setup, if you are defining several strings for
a viewport, all strings defined for that viewport are displayed on the screen.
The currently selected string is displayed in red. Other strings appear in
green. Should any part of the strings overlap, the overlapping portions will
be displayed in yellow.
String Numerical Order: Strings within a given serial port or viewport are
processed for each inspection in numerical order, so that lower–numbered
strings are transmitted (displayed) before higher–numbered strings which are
transmitted (displayed) for the same inspection.
