Technical Details

what runs on :3620

Epson projector implementations commonly use TCP port 3620 for the ESC/VP-style network control protocol, carrying short, text-oriented command and status exchanges after a connection is established. Commands can control functions such as power, source selection, and configuration, while queries return projector state; exact commands and framing vary by model and firmware. The registration covers both TCP and UDP, although TCP is the usual observed control transport. This service is distinct from PJLink, which commonly uses TCP port 4352.

security overview

Traffic is generally unencrypted, and projector-control deployments may provide little or no authentication at the protocol layer. An exposed service can therefore allow remote power or input changes and disclose device status; it should normally be restricted to the AV management network or protected with firewall rules and, where supported, projector access controls.
