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 Micro125-to-Micro125 communication. Be sure to configure both Micro125
devices with the same encryption key.
Third-party application to Micro125-encrypted communication: Micro125 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 Micro125.
Lantronix Secure Com Port Redirector provides an encrypted connection from Windows-
based applications to the Micro125. Information about SCPR is available on our web site,
