想同时发送数据到多台设备时，用UDP代替TCP，将通信地址设置为广播(Broadcast)IP地址使用即可。如此构成可代替RS485网络。广播IP地址的各类别及各子网掩码都不相同。

*参考1: UDP 通信模式

下面是利用EZL-200F的构成例。

- 所有ezTCP 有线网络/无线网络产品系列可构成相同配置。

[EZL-200F的设定]

ezTCP Mode	UDP(U2S)
Local IP Address	192.168.0.1
Subnet Mask	255.255.255.0
Gateway IP Address	192.168.0.254
Peer IP Address	192.168.0.255 (broadcast IP)
Local Port	1470
Interval(10ms)	0
Block(Byte)	0
Peer Port	1470

[PC #1]

Local IP Address	192.168.0.2
Subnet Mask	255.255.255.0
Gateway IP Address	192.168.0.254
Local Port	1470

[PC #2]

Local IP Address	192.168.0.3
Subnet Mask	255.255.255.0
Gateway IP Address	192.168.0.254
Local Port	1470

[PC #3]

Local IP Address	192.168.0.4
Subnet Mask	255.255.255.0
Gateway IP Address	192.168.0.254
Local Port	1470
