Telnet TCP or Raw TCP Port

Question

I am testing a Digi One SP using a TCP Sockets Profile. Should I use the Telnet TCP port or the Raw TCP port with my ethernet connection port setting in my Scale Interface software? Thanks!

Answer 1

That really depends on your ETHERNET host.

"Telnet" encodes certain commands which are not data, so can do things like change baud rate, etc. So a true binary protocol like Modbus/RTU can't move through "telnet" easily as telnet does byte-stuffing & other changes in data.

If in doubt, try the RAW first.
