Table 3-29 Description of serial application parameters
Parameter Description
Baudrate
Indicates the number of bytes per second transmitted by the Router,
commonly used baud rate is 115200, 57600, 38400, 19200.
Databit
The number of data bit can be 4, 5, 6, 7, 8, and usually in ASCII code. The
transmission starts from the lowest bit and is located by the clock.
Stopbit
Indicates the end of a character data. It can be a high level of 1-bit, 1.5-bit
and 2-bit.
Parity
Indicates the data error checking method used by a set of data: Odd or
Even.
Flow Control Includes hardware and software.
Protocol
The following protocols are available:
UDP (DTU): Serial port to UDP connection, including custom 
application layer protocol, which is equivalent to the function of a IP
modem
Pure UDP: Standard serial port to UDP connection. 
TCP (DTU): Serial port to TCP connection, including custom 
application layer protocol, which is equivalent to the function of an IP
modem.
Pure TCP: Standard serial port to TCP connection. 
TCP server: Standard TCP server connection. 
TCST: Custom TCP connection. 
Modbus TCP: Modbus protocol based on Ethernet TCP/IP. 
DCUDP: UDP connection in CUDP mode. 
DCTCP: TCP connection in CTCP mode. 
Server Address The IP address or domain name of the data service center.
Server Port The listening port of the data service center.
