Encryption only applies to the port selected for data tunneling (default 10001), regardless of
whether you are using TCP or UDP.
Generally, one of these situations applies:
Encrypted xDirect-to-xDirect communication. Be sure to configure both xDirect devices with
the same encryption key.
Third-party application to xDirect-encrypted communication: xDirect uses standard AES
encryption protocols. To communicate successfully, products and applications on the peer
side must use the same protocols and the same encryption key as the xDirect.
Lantronix Secure Com Port Redirector provides an encrypted connection from Windows-
based applications to the xDirect. Information about SCPR is at www.lantronix.com/device-
networking/utilities-tools/scpr A 30-day trial version of SCPR is available.
