What are the advantage of rs232?

Answer 1

Ethernet is a networking interconnect system that allows multiple communication paths to exist simultaneously. It provides high speed communiction.

Most new computers have at least one Ethernet interface. These interfaces usually include DC electrical isolation with a transformer.

Generally fewer feet of cable would be needed than for an RS232 system. Maximum copper wire cable length is 100 meters (328 ft) without repeaters. This means that from an Ethernet switch (this not a mechanical switch) centrally located you can serve machines within a 200 meter diameter.

If your CNC has a built-in Ethernet capability you may have some features that make file transfer easy.

Ethernet provides good ground loop noise immunity.

We have an Ethernet to RS232 device identified as E232 that allows any HAAS and some others to connect to an Ethernet network and work at 115.2 kbaud.

RS232 as normally used is a direct electrical connection from your computer to CNC. This has some major problems. Ground loop noise sensitivity, easily damaged from electrical faults, limited cable length. Working cable length is inversely proportional to cable length.

RS232 is low cost.

We have another product, I232, that provides electrical isolation (greatly reduces noise problems and damage from electrical faults), high baud rate at long distances. With the I232 system we can send error free data at 115.2 kbaud over a 4000 ft cable with 1000 V RMS 60 Hz applied to the interconnect cable. That is a +/-1414 V signal. The I232 System is an RS232 to RS232 interconnect system.
