B. Printable Prefix Codes
Since the Prefix code is transmitted through the opened port, it is
best to select a non-printable Prefix Code. The procedure for
selecting the Prefix Code is described in Section 3. If your
application requires a printable code, refer to the ASCII code
chart below. Remember:
·
Switch positions 1 - 7 correspond to ASC bits B1 - B7 on
the chart.
·
Switch positions should be ON for a 0 and OFF for a 1.
Example:
To select the “
@
” character for a printable Prefix
code: B1 - B7 on the chart shows 0 0 0 0 0 0 1 for “
@
”.
Therefore, Sw1 - Sw6 should be ON and Sw7 OFF.
