Table 23: Default Dipswitch Settings
Note
Parity and data bit setting are dependent. You may select either no parity
with 8 data bits or even parity with 7 data bits.
There is no stop bit setting. RS-232 communications uses 1 stop bit
under all circumstances. This setting
cannot
be changed.
If the initial settings, listed in Table 25, page 125, are not appropriate for your application, refer
to Table 24, page 123, for switch settings you can use to change the baud rate, parity and data
bits, and end-of-line delimiter.
