2.1.5.1 Predefined Message
The predefined message frame allows the selection of four pre-defined messages. The Message Index
dropdown box has three indexes listed as 0, 1 and 2. When each index is selected, the message is
displayed in the LCD display box exactly as it appears on a 2 row by a 16 column LCD display.
Messages are shown in Figure 8. Clicking the Send button transmits the command to the device and the
corresponding message appears on the LCD display. Note the Cursor Position sub-frame is disabled
when the predefined message button is selected as the line and column selections are not used.
This command should not be executed if the device does not contain an LCD display.

2.1.5.2 User Defined Message
The User Defined Message allows the user to write any alphanumeric message to the LCD. The
message text is entered into the LCD text box and the Cursor Position sub-frame enables the Line and
Column dropdown boxes. This allows the user to select exactly where in the LCD display the text will
begin to be written. The default setting is Line 0 and Column 0. This corresponds to the upper leftmost
cursor position in the LCD display. The lower rightmost cursor position is defined as Line 1, Column 15.
Only one character can be written at this location as it is the last position in the LCD display and any
subsequent characters will be concatenated. The message is shown in the LCD display box exactly as it
appears on an LCD display. All other data on the display that is not defined in the specified text locations
will remain unchanged. Clicking the Send button transfers the command and display the text to the
device’s LCD display.
This command should not be executed if the device does not contain an LCD display.
