4.4 Keyboard Translator
The keyboard translator is an interface which switches the signal
from the membrane keypad to the standard AT keyboard. There
are six connectors on the board. On top of the board, there are two
connectors linking two flat cables with the larger membrane
keypad (as shown in Fig. 4-5). On the side of the board, there are
four connectors. For connection details, refer to Fig. 4-5.

unit. (See Fig. 2-1.)
3. Pull out the work drawer out as far as it will go.
4. Remove the keypad connector protective bracket.
5. Carefully detach all cables connected to the keyboard
translator. (See Fig. 4-5.)
6. Unscrew the four screws on the corners, pull out the keyboard
translator, and replace it.
