FAQ:

Q: What is modmodbus and RS-232?

A: Modbus is a protocol that runs on top of a serial connection. It defines messages and their content. RS-232 and RS-485 (and sometimes “TTL”, for 0.8V/2.0+V levels) are physical implementations of a serial connection.

Q: What is the difference between RS485 and RS232?

A: RS232 is a standard that defines a physical communication scheme using a serial connection. Similarly RS485 does the same. Both of these standards dictate the physical serial bus (with voltage levels and timing details) behind the communication scheme (that could be ModBus or a proprietary printer peripheral comm protocol)

Q: How to split Modbus data on a serial port?

A: Virtual COM Port Driver Pro by Electronic Team is an excellent solution for splitting Modbus data. The application splits serial port traffic by duplicating data received by a COM port and forwarding it to an unlimited number of virtual or real serial interfaces.

Q: Is there a Modbus to Ethernet connector available for Windows?

A: There are Windows and Linux versions of Modbus to Ethernet Connector available. Please note that the Linux solution operates with a command-line interface. QModMaster is a Qt-based app that simulates a master Modbus device.
