CNC transfer
Why place an Ethernet-to-serial adapter near an older CNC?

Direct answer
RS-232 becomes more sensitive to distance, grounding, interference, and baud rate as cable length grows. An industrial device server lets Ethernet cover most of the distance and keeps the vulnerable serial cable short near the control. It also centralizes IP-based management while preserving the CNC's existing serial interface.
Practical checkpoint
Document the adapter IP, MAC address, serial parameters, physical machine, and recovery credentials before commissioning it.
