Ultimate Technology 500 POS Examples of Remote Programming for KEY MAKE/BREAK Code, Where A0

EXAMPLES OF REMOTE PROGRAMMING FOR KEY MAKE/BREAK CODE

EXAMPLE 1.

This example programs a key located at the top left-hand corner of the keyboard (row 1, column

A)as a primary key that outputs the scan code for lowercase "z" on MAKE and BREAK.

1.Use the data in Appendix D to find the key code number for the "Z" key on the 101/102- keyboard. The "Z" key code number = 46 (decimal).

2.Convert key code 46 (decimal) to its hexadecimal equivalent. The key code = 2E hex.

3.Programming command = A0krcCxDx<CR> = A0 P 1 A CED2!-<CR>

WHERE: A0	= Op Code (1 byte hexidecimal)
k	= P to program Primary key
	S to program Secondary key
r	= Row in ASCII
c	= Column in ASCII
Cx	= Low nibble of hex value
Dx	= High nibble of hex value
	Where x = 0-9, A-F

!= start BREAK code phase of key

- = BREAK code of previous key <CR> = terminate command (0D hex)

EXAMPLE 2.

This example programs the key at top left-hand corner of keyboard (row 1, column A) as a primary key that outputs the scan code for uppercase "Z" on MAKE and BREAK.

1.Use the data in Appendix D to find the key code number for the "Z" key on the 101/102- keyboard. The "Z" key code number = 46 (decimal).

2.Convert key code 46 (decimal) to its hexadecimal equivalent. The key code = 2E hex.

3.Programming command = A0krc(CxDx)<CR> = A0 P 1 A ( CE D2 ! - ) <CR>

Parameters same as shown for example 1, except () = left shift MAKE and left shift

BREAK
