Unitech KP3800 - Use Numeric Keypad

9Keyboard Manual
Keyboard Wedge, continued
Use Numeric Keypad
The ASCII code for numeric input from the keypad part of the
keyboard is different from that of the upper row of the keyboard
proper. Some accounting programs specifically require keypad
input, and for that reason, the keyboard decoder can output
scanned or read numbers as either keypad or keyboard (upper row)
output.
Default is “No”.
