4.3 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 membrane keypad (as
shown in Fig. 4-3). On the side of the board, there are four connec-
tors. For connection details, refer to Fig. 4-4.
When servicing the keyboard translator:
1. Switch off the power, and detach the main power cord.
2. Disassemble the AWS-8430. The translator will be located in
the left part of the front panel. (See Fig. 1-2.)
3. Remove the keypad connector protective bracket.
4. Carefully detach all cables connected to the keyboard
translator. (See Fig. 4-3.)
5. Unscrew the four screws on the corners, pull out the keyboard
translator, and replace it.
