6: Serial Port Configuration
To attach the serial device to the LS100W serial port, its serial port operation should match exactly to
that of the serial device. Serial port configuration parameters are summarized in Table 6-1.
Table 6-1. 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
LS100W does not support. The LS100W does not support 7 data bits, No parity, 1 stop bit
configuration. In this case, the LS100W will operate as 7 data bits, No parity, 2 stop bit mode. In case
the LS100W is configured as 8 data bits, Even(or Odd) parity, 2 stop bits mode, the LS100W will
operate as 8 data bits, Even (or Odd) parity, 1 stop bit mode.
The factory default setting of the flow control is None. Only hardware flow control using RTS/CTS is
supported by the LS100W. Hardware flow control method controls data communication flow by
sending signals back and forth between two connected devices.
