@Juan_Mu_oz2717 here are a few use case scenarios we have for your reference.
A typical topology could be:
[Serial Device] <~RS232 connection~> [Serial Interface | Peplink | WAN/VPN] <===IP Connection===> [VPN/WAN | Peplink | LAN] <===IP/Ethernet===> [PC/Host with Terminal Emulation Program]
See if that helps.
