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
