3.3.19. COM Configuration
Configure serial settings in this page (Figure 3.34). Note that these settings need to match the ones in the serial
device.
Alias Name:
This field is for identification purpose only.
Baud Rate:
Select one of the baud rates from the dropdown box, or select Other and then enter the desired baud rate in the
input box. Baud rates higher than 230400bps are not supported.
Parity / Data Bits / Stop Bits:
Configure them accordingly.
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, SE5001A 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 of packing data in the serial communication. It is designed to keep packets in track.
SE5001A provides two types of delimiter: Time Delimiter, and Character Delimiter. When the selected delimiter
condition is met, SE5001A would transmit the serial data in its buffer over the network.
 Time Delimiter: SE5001A 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 SE5001A will push out its
serial buffer if it does not receive any serial data with in 2ms. This delimiter is selected by default.
 Character Delimiter: will transmit the serial data in its buffer when it sees the incoming data include the
specified character (in HEX format). This field allows one or two characters. If character delimiter is set to
0x0d, SE5001A will push out its serial buffer when it sees 0x0d (carriage return) in the serial data.
