Simplify supports a **Tactile Keypad** message on all Tetra devices. This message displays up to three lines of text and an input field showing formatted user input. Allowed input consists of numbers keyed on the device keypad.

A Mask subfield in API 5001 in the request defines how the input field is initialized, the maximum number of digits allowed in user input, and how the input will be formatted. A Direction subfield can be used to determine the direction in which the input field is filled. API 5001 must be terminated with a field separator. See under Request for more information.

If the customer presses the Enter key, the user input is returned in the response, formatted as defined by the Mask (except no Input Mode masking). A timeout field in the request defines how long Simplify will wait in the middle of user input. The timeout counter starts when a digit is entered and is reset whenever a new digit is entered. If the counter expires with no additional input, the input field is reset to blanks. If the format mask contains at least one \'\/D\', the Enter key can be pressed with no data input, and the function will return exactly what is in the input box (default). If the format mask does not contain at least one \'\/D\', a guidance message stating data input is required will be displayed.

|FS	|1	|Field separator (Hex 1C)|


### Mask

The Mask functionality supported for this message is a subset of that supported for the Virtual Keyboard message (see under Tag 030 for detailed description). It can contain format constants ('$', '(', ')', '-', etc.) and format characters. The only format characters supported are /d and /D:
- **/d** accepts a numeric character (decimal). Initialized as a blank space.
- **/D** accepts a numeric character (decimal). Initialized as 0. 

Example: The initial display for Mask = $/d/d/d/D./D/D is $   0.00 

### Direction

A value of 1 (left to right) is only valid if Mask is defined. If Direction is blank, invalid, or not present, a default of 0 (right to left) is used. 

Example: If Mask = $/d/d/d/D./D/D and Direction = 0, and user enters 5000, the formatted input will be $  50.00.

:::::notice{important}
If Direction = 1 and user enters 5000, formatted input for the above Mask will be $5000.
