LOCAL MODE PROGRAMMING
KEY MAKE/BREAK CODES AND EXTENDED FUNCTIONS
There are two scan codes assigned to each key, one for when the key is depressed (MAKE code) and the other for when the key is released (BREAK code). Generally, all keys are programmed to output both MAKE and BREAK codes. The SHIFT, CONTROL and ALTERNATE keys are always programmed to output MAKE and BREAK codes so that the system can tell if the key is being held down.
Other programming commands are provided in the local programming mode to enable the user to customize the keyboard output. These commands entered at the Series 600 Keyboard numeric keypad are summarized in Table 4. Some typical programming examples using these commands follow the table.
