Baudrate
The unit and attached serial device, such as a modem, must agree on a speed or
baud rate to use for the serial connection. Valid baud rates are 300, 600, 1200, 2400,
4800, 9600 (default), 19200, 38400, 57600, 115200, and 230400 bits per second.
XPort Direct+ and later models also support high-performance baud rates of 460800
and 921600 bits per second (see
I/F (Interface) Mode
The Interface (I/F) Mode is a bit-coded byte entered in hexadecimal notation.
The following table displays available I/F Mode options:
Note:
All bit positions in the table that are blank represent "don't care" bits
for that particular option, which can be set to either a 0 or 1 value.
(1) 2 stop bits are implemented by the software. This might influence performance.
The following table demonstrates how to build some common Interface Mode
settings:
Additional settings for RS-422 4-wire and RS-485 2-wire are available.
Note:
All bit positions in the table that are blank represent "don't care" bits,
for that particular option, which can be set to either a 0 or 1 value.
