Application Creation
Min Len and Max Len
The Min Len property sets the minimum length the bar code must be in order to qualify as a
valid bar code. The Max Len property can be set to limit the length of the data for a particular
field. The properties work in conjunction. The Optimizer program automatically limits the values
available. If the maximum length is longer than the field can display, the entered data will left-
scroll or move to the next field if the data type of the next field is EXTENSION. If the length of a
bar code is longer than the maximum length, the system will prompt a warming message to the
user. The maximum length can contain up to 80 characters*.
Input Type
The input type property determines how data will be entered. There are three options available.
1. Scanner
2. Keypad
3. Both
Each option will limit the manner in which data is entered. To ensure that data is entered
correctly be sure to consider the restrictions of each option when making the selection. If the
form is setup to only accept data via the keypad, then it will not validate data from the scanner.
This is also the case should the Scanner be the option selected. Selecting the Both option can
eliminate potential conflict problems.
Prompt
The Prompt property specifies the text that will appear on the display of the Optimus when the
particular form is selected and active. There are a maximum of eight prompts per form that can
be utilized. To enter information in a prompt field box, click on the selected field and enter the
applicable information. It is important to note that information cannot be entered into this field if
no data type is selected. It is important to note that the information cannot be entered into this
field if no data type is selected.
Data Type
Specify the data type for each field. There are 12 types available. Following are the details.
Null
Null is selected if there is no selection for the particular field. If null is selected there will be
no prompt displayed on the screen.

This is the maximum number of characters for the OptimusS and OptimusR application templates. The OptimusS WLAN and
