The EIA standards are physical layer interfaces that use communication converter chips to convert the way that signals are transmitted to and from different types of devices. Data rate, driver load, maximum driver output voltage, baud rate, etc. all differ between the three standards. Sometimes, ...
A USB serial converter can be used. Modbus TCP/IP: Select TCP/IP if you want to communicate with a MODBUS TCP/IP network. In this case, slave ID is the same as the Unit ID used in MODBUS TCP/IP. The port number is default 502. If the connection fails, try to ping your device ...
Gateway is also called inter network connector and protocol converter. Gateway is a device that acts as protocol conversion or communication mode conversion. Data gateway can connect different communication protocols, and even can be used between two communication protocols with different architectures. ...
