Technical Support: h.usriot.com 2.2.2. Serial Package Methods For network speed is faster than serial. Module will put serial data in buffer before sending it to network. The data will be sent to Network as Package. There are 2 ways to end the package and send package to network - Time Trigger Mode and Length Trigger Mode.   Time Trigger Mode: Default package time is 4 bytes sending interval and use can set between 0~65535. Length Trigger Mode: Default package length is 1460 and user can set between 0~1460. 2.2.3. Baud Rate Synchronization When module works with USR devices or software, serial...

Technical Support: h.usriot.com Figure 13 Modbus Master mode configuration A.Work Mode: Four types work modes. B.Enable Modbus Over TCP/IP: Open this function, M511 will work in transparent transmission and don’t proceed protocol conversion. If network side protocol is Modbus RTU/ASCII, this function must be used. If network side protocol is Modbus TCP, this function can’t be opened. C.Remote Server AddrA: Modbus Slave address, can be domain name. D.Remote Port NumberA: Default port is 502 and often keep default value. E.Slave ID Range: All querying command will be sent to this Slave in this...
