4.8.1.9.10.1 Text Fields
– Field Type 1
Text Fields are used to display a string of ASCII characters. Up to 195 characters may be displayed in a
field. For a list available fonts refer to
Table 9: Text and Symbol Fonts.
The ASCII text is set using
the GnnT”Text” command where the characters to be displayed are enclosed in
the quotation marks. If a quotation mark is required in the test, it must be preceded by the backslash
character. For example to set the text string for Field 7 to display Model "DX-2200-TI" use the command
G07T"Model \"DX-2200-TI\"".
The color and transparency of the character can be configured using GnnRrrr, GnnGggg, GnnBbbb to set
the red, green and blue component of the character color and GnnAaaa to set the transparency. Similarly,
the background can be configured using GnnBRrrr, GnnBGggg, GnnBBbbb to set the color and GNBAaaa to
set the transparency. The parameters rrr, ggg, bbb, and aaa must be in the range 0 to 255. For
transparency, a value of 0 is fully visible and a value of 255 is fully transparent. The default text is white and
fully visible. The default background is blue and fully transparent.
Coordinate A of the Graphic Field is used to specify the position for the top-left corner of the Text.
Coordinate B is not used for Text Fields.
