5: Serial Port Configuration
To attach the serial device to the NEMO10 serial port, its serial port operation should match exactly to
that of the serial device. Serial port configuration parameters are summarized in Table 5-1.
Table 5-1. Serial Port Configuration parameters
Parameter
Values
Baud rate
1200, 2400, 4800, 9600, 19200, 38400, 57600, or 115200
Data bits
7 bits or 8 bits
Parity
None, Even or Odd
Stop bits
1 bit or 2 bits
Flow control
None, Hardware (RTS/CTS)
DTR option
Always HIGH, Always LOW, or Show TCP connection
DSR option
None, Accept TCP connection only by HIGH, or
Open/Close TCP connection
Inter-character timeout
Inter-character timeout value in milliseconds
To configure serial port parameters, use ‘set’command as follows:
set
serial
baudrate
data_bits
parity
stop_bits
flow_control
dtr_option
dsr_option
interchar_timeout(ms)
where,
baudrate: 1200, 2400, 4800, 9600, 19200, 38400, 57600, or 115200
data_bits: 7=7-bits / 8=8-bits
parity: n=none / e=even / o=odd
stop_bits: 1=1-bit / 2=2-bits
flow_control: n=none / h=hardware
dtr_option: h=always high / l=always low / s=show tcp connection
dsr_option: n=none / a=accept only by high / o=open,close TCP connection
interchar_timeout: inter -character timeout value in milliseconds
The factory default settings of
baud rate, data bits, parity
and
stop bits
are
9600, 8 data bits, No-
parity and 1 stop bit
respectively. Among the serial configuration, there are three serial modes the
NEMO10 does not support. The NEMO10 does not support 7 data bits, No parity, and 1 stop bit
configuration. In this case, the NEMO10 will operate as 7 data bits, No parity, 2 stop bit mode. In case
the NEMO10 is configured as 8 data bits, Even(or Odd) parity, 2 stop bits mode, the NEMO10 will
operate as 8 data bits, Even (or Odd) parity, 1 stop bit mode.
