The bits/char selections are 7 or 8. The channel transmits the selected
number of data bits per character. The channel only accepts characters
received with the selected number of data bits per character. The default
selection is 8 data bits per character.
The ASCII code size selections are 7 or 8. You use this selection when 8
data bits per character is selected. Then select one of the following:
If you select: Then:
7
8
The RSĆ232ĆC communication channel uses the first 7 bits only
in decoding the character transmitted.
The RSĆ232ĆC communication channel uses all 8 bits in
decoding the character transmitted.
The default ASCII code size is 7.
The reconfigure selection implements the channel 5 selections. For
example, if you select CRT defaults, the 1775-S4B scanner does not
implement the change until you select reconfigure. In response to selecting
reconfig:

the reconfiguration selection disappears.
