User Manual V. 1.1
 Flow Control, Choose between No Flow Control, RTS/CTS (Hardware Flow Control),
DTR/DSR, Xon/Xoff (Software Flow Control). If Xon/Xoff is selected, Xon and Xoff
characters are changeable. Defaults are 0x11 for Xon and 0x13 for Xoff. If the serial
device uses Xon/Xoff in conjunction with DTR/DSR, enable Controlling DTR to
simulate receiving Xon/Xoff and reading DSR to get Xon/Xoff currently.
 Empty Serial Buffer When TCP Connection is Established, By default, SE5002D will
empty its serial buffer when a new TCP connection is established. This means that the
TCP application will not receive buffered serial data during a TCP link breakage. To keep
the serial data when there is no TCP connection and send out the buffered serial data
immediately after a TCP connection is established, set this option to No.
 Data packet delimiter, Packet delimiter is a way for packing data in serial
communications. It is designed to keep packets in track. SE5002D provides two types of
delimiters: Time Delimiter, and Character Delimiter. When the selected delimiter
condition is met, SE5002D would transmit the serial data in its buffer over the network.
 Time Delimiter, SE5002D will transmit the serial data in its buffer when the
specified time interval has reached and no more serial data comes in. The default
time is 2ms, which means SE5002D will push out its serial buffer if it does not
receive any serial data within 2ms. This delimiter is selected by default.
 Character Delimiter, will transmit the serial data in its own buffer when it sees the
incoming data include a specified character (in HEX format). This field allows one or
two characters. If it is set to 0x0d, SE5002D will push out its serial buffer when it
sees 0x0d (carriage return) in the serial data.
 COM Type Selection, select between RS-232, RS-422 and RS-485. Note that RS-485
refers to 2-wire RS-485 and RS-422 is compatible with 4-Wire RS-485.
