SE5001A Serial Device Server

3.3.16. UDP Application: Multi-Point Pair Connection

It is also possible to setup pair connection in UDP mode to have more than one Pair Connection Master or Slave to

communicate to each other. For example, it is possible to setup one Modbus Master and six Modbus Slaves in UDP

(Figure 3.31). Note again that UDP does not guarantee data delivery and only data would be transmitted over

Ethernet; other serial pings are not transmitted. If RS-232 along with flow control, it is recommended to use

Multi-Point Pair Connection in TCP (section 3.3.18).

 Note that the Destination IP and Port of the Slaves need to be equal to the Master’s IP and Port. Local

Listening Port of the Slaves needs to be equal to the Master’s Destination Port.

Sample Configuration:
