Figure 3.30 TCP Client in Link mode
3.4.3 UDP for Link Mode
UDP is a fast but non-guaranteed datagram delivery protocol. Serial Server can be configured in a UDP mode on a
TCP/IP Network to establish a connection, using uni-cast or broadcast data to and from a serial device to one or
multiple host computer,.
Serial Server can be configured in a UDP mode to establish connection using uni-cast or broadcast data from the
serial device to one or multiple host computers. Vice versa is also true. For example, The original RS-422/ RS485
bus is transferred and extended connecting distance by Serial Servers, The destination IP is assigned by single IP
or group IPs, The configuration is limited by the Local Listening Port (For example, on Serial Server listening port is
4660 which receive data sending from the host computers) Serial Server can support up to 8-group IP for UDP
connection, if users needed.
If yo u check “Apply to all serial ports”, it will configure all of the serial ports.
