Appendix D: The LK461 Keyboard

Some of the computers manufactured by Compaq® subsidiary Digital Equipment Corporation come with a special keyboard called the DEC LK461. The Matrix ServSwitch supports this keyboard by passing through unaltered the scan codes of certain proprietary keys (such as [Help] and [Do]) and remapping others (such as [PF1] through [PF4]). The Switch maps the special keys of the LK461 as shown in the table below. Note that the LK461 has no Num Lock LED and its Hold Screen LED is equivalent to the Scroll Lock LED on other keyboards.

*Keypad [–] is always mapped this way in Mode 2; in Mode 3, the mapping varies by country.

**This mapping varies by country; that is, the key is mapped differently depending on what keyboard country or language the CPU is configured to accept.
