FAQ:

Q: Is 485 and Ethernet the same?

A: While Ethernet is the most commonly used communication protocol among multiple types of devices, ranging from consumer gadgets to industrial devices, TIA/EIA-485 commonly known as RS-485 is still broadly used in industrial devices even if it is older than Ethernet. Let’s see why it is still in use and why, at Robotiq, we decided to use it as the standard communication protocol for our devices.

Q: What is serial to Ethernet?

A: A Serial to Ethernet converter, also called a serial device server, is a very useful device for accessing a serial device over a local LAN network or even over the Internet. The Serial to Ethernet converter converts a serial RS232, RS485 or RS422 signal to a packet sized data signal which can be sent over any Ethernet network .

Q: Is Ethernet serial communication?

A: Ethernet is a type of serial communication. There are many differences between Ethernet and other serial protocols though. The voltage levels and cable impedances are different but the primary difference is that Ethernet is an intelligent communication while RS422, RS232 are not.
