the current match codes and loading new match codes. Auto Load (INPUT)
does not cause match code data to be loaded into match table entry #8.
Auto Load (INPUT) is useful in product verification applications where new
match codes need to be loaded into the decoder on a regular basis. When a
new product label needs to be entered into the match table, an Auto Load
pushbutton is pressed by an operator. Then, a sample of the product is run by
the scanner. The new match code is automatically entered. If a display is
connected to the AUX port, you can then read and verify the match code
value.
