No.75 How can I send data to multiple servers. (UDP broadcast) 09-12-2011
Category : how to

As a RS485 network if you wish to send data to multiple systems at the same time, try to use UDP with broadcast IP address.

ezTCP supports the UDP communication mode.
In the case of EZL-50 and EZL-60, download UDP(U2S) firmware using HotFlash, and in the other products, set UDP(U2S) with a setup program such as ezConfig.

Since broadcast IP differs depending on the network environment,
make inquiry through the question-and-answer bulletin board.
(Your question should include local IP, subnet mask and gateway IP.)

The following is a setting example.
