Display Mode
This Numeric point sets the display mode of the module. The table below explains the
available modes. More detailed descriptions follow the table.
Value Mode Description
0 Menu This mode is for displaying static messages such as system status or for
presenting menu-type selections for a user. No editing via the keypad is supported,
however, any key presses detected are returned to the controller via the
ACCLCDKeyStroke system variable.
1 Numeric Data This mode is designed to display prompt information on the first two lines and
numeric data that may be edited on the third. The data may be edited using the
numeric keys. The cursor will automatically advance after entering each digit. The
first number of the third line is sent to the Controller in the ACCLCDAnswerStr
system variable after pressing the ENTER button.
2 String Data This mode is designed to display prompt information on the first two lines and
string data that may be edited on the third. All 16 characters of the string may be
edited using the keypad. The cursor will automatically advance after entering each
character. The edited string is sent to the Controller in the ACCLCDAnswerStr
variable after pressing the ENTER button.
3 DateTime Data This mode is designed to display prompt information on the first two lines and
date/time data that may be edited on the third. Only numbers and the am/pm
indicator may be changed: all delimiters (: or / or .) are skipped. The cursor will
automatically advance after entering each digit. The edited string is sent to the
Controller in the ACCLCDAnswerStr system variable after pressing the ENTER
button. The numbers can only be changed to valid values (1 to 12 for month, etc.)
The valid selections wrap from highest valid value to lowest valid value and vice
versa.

Detailed Mode Descriptions
Menu mode
This mode allows you to display your information on all four lines of text without
restriction. There is no automatic editing capability built-into this mode. The text
displayed on lines 1 – 4 of the LCD display is determined by the strings
ACCLCDDispLine 1 – ACCLCDDispLine 4, respectively.
All key entries on the keypad will be sent to the Controller in the ACCLCDKeyStroke
numeric.
Numeric Data mode
This mode is designed to display two lines of prompt information and a third line
containing a numerical value that can be edited right from the keypad. This numeric data
might be a set point, point value or other data. Editing functions such as automatic
cursor positioning and key acceptance is performed locally by the xPDISPLAY.
In this mode, the text on lines 1, 2 and 4 of the LCD display is determined by the strings
ACCLCDDispLine1, ACCLCDDispLine2 and ACCLCDDispLine4.
Line 3 of the display contains the string containing any combination of letters and
numbers set by ACCLCDDispLine3. The entire line is editable and can contain numeric
values, a decimal point, and plus or minus sign. The cursor automatically advances after
entering each digit. The time delay between pressing the key associated with the
number and the cursor advance is determined by the setting called “Auto Accept” found
on the Setup menu page. The default time delay is 0.8 seconds.
Only the numbers contained on line 3 are sent to the controller when Enter is pressed.
Example: If line 3 contains “TEMP= 73 F”, only the “73” is returned. Invalid entries would
contain no numbers or numbers greater than nine digits in length.
Only the up arrow key, down arrow key and three soft keys are sent to the Controller in
the ACCLCDKeyStroke numeric. All other keys are used locally by the display unit for
data entry and editing. The left and right arrows can be used to position the cursor. The
* key can be pressed for a space character. The # key will delete with contraction.

xPDISPLAY Installation & User’s Guide 13
String Data mode
This mode is designed to display two lines of prompt information and a third line
containing a string that can be edited right from the keypad. Editing functions such as
automatic cursor positioning and key acceptance is performed locally by the xPDISPLAY.
In this mode, the text on lines 1, 2 and 4 of the LCD display is determined by the strings
ACCLCDDispLine1, ACCLCDDispLine2, and ACCLCDDispLine4.
Line 3 of the display contains the string set by ACCLCDDispLine 3. All 16 characters of
line 3 are editable and can contain any of the xPDISPLAY alpha-numeric key entries. If no
activity is detected for a brief interval, the xPDISPLAY will Auto-Accept the key entry and
automatically advance the cursor. The default time for Auto-Accept is 0.8 seconds,
however, this time can be adjusted from 0.8 seconds to 5.0 seconds by setting the Auto
Accept value through the SETUP mode. If a different key is pressed prior to the Auto-
Accept time expiration, the xPDISPLAY automatically shifts the cursor to the next position.
Line 4 can be used to define the soft key functions.
Entering Text
Successive presses on the alpha-numeric keys cycle between the numeric value, the
upper-case alpha and the lower case alpha values. For example:
To enter the letter: Press this button (number of times)
A 2 (one time) ABCabc2
w 9 (five times) WXYZwxyz9
The “1 + -“ key toggles among “1”, “+”, “-“ and all punctuation marks shown in the table on
page 17 that are not letters or digits.
The “*” key is used to enter a space character. The left and right arrow keys move the
cursor accordingly.
Only the UP ARROW, DOWN ARROW and three soft key entries are sent to the
Controller in the ACCLCDKeyStroke numeric. All other keys are used locally by the
xPDISPLAY for data entry and editing.
DateTime Data mode
This mode is designed to display two lines of prompt information and a third line
containing date/time information that can be edited right from the keypad. Editing functions
such as automatic cursor positioning and key acceptance is performed locally by the
xPDISPLAY.

14 Andover Controls Corporation
In this mode, the text on lines 1, 2 and 4 of the LCD display is determined by the strings
ACCLCDDispLine1, ACCLCDDispLine2, and ACCLCDDispLine4.
Line 3 of the display contains the string set by ACCLCDDispLine 3. This string is expected
to be filled by a DateTime as follows:
Standard: mm/dd/yy hh:mmxm x = a or p
European: dd/mm/yy hh:mm
If the string sent in ACCLCDDispLine 3 is not in the above format, the xPDISPLAY will
format the string accordingly. It expects 5 numeric fields, from left to right, separated by
a delimiter. If there are less than 5 numeric fields, the remaining fields default to 0. In the
case of Standard time, it scans for the first occurrence of a “pm” or “PM”. If it finds either,
it sets the “pm”, otherwise the default is “am”. This re-formatting of the Display Line 3
string occurs to facilitate editing and checking the datetime. The xPDISPLAY always re-
formats the ACCLCDDispLine 3 string when the mode is set to ACCLCDTimeFormat.
The string is edited using the numeric keys. The cursor automatically advances after
entering each digit.
In Standard time, cursor over to the corresponding display position and press the “2
ABC” key to set it to “am”. Press the “7 PQRS” key to set it to “pm”.
Line 4 of the display is used to define the 3 soft keys.
Only the UP ARROW, DOWN ARROW and three soft key entries are sent to the
Controller in the ACCLCDKeyStroke numeric. All other keys are used locally by the
xPDISPLAY for data entry and editing.
After the Enter key is pressed, the xP Display validates the date time entered in line 3. If
valid, the contents of line 3 are returned in ACCLCDAnswerString. If not valid, a short
beep sounds and “Invalid Entry” is displayed briefly on line 4 before reverting back to the
original line 4 contents. The cursor is displayed at the first offending character for invalid
entries.
