If RS232_1 is selected
Baud rate 4800
9600
19200 *
38400
Selects the data transmissio n rate (bau d rate)
(baud = bit per second).
Data bits 7
8*
Selects the number of data bits per data byte.
Stop bits 1 *
2Selects if one or two stop bits are used per
data byte.
Parity Even
Odd
None *
The parity test for received data bytes can be
selected. None causes transmission in both
directions without parity bit. If Even or Odd is
selected, the bytes are ch ecked if they have
even or odd parity.
Protocol Ready/Busy *
Xon/Xoff Selects the type of protocol, i.e . a certain set of
rules and procedures for ensuring error-free
