Encryption only applies to the port selected for tunneling data (default 10001),
regardless of whether you are using TCP or UDP.
Generally, one of two situations applies.
Encrypted SDS-to-SDS communication. Be sure to configure both SDS
devices with the same encryption key.
Third-party application to SDS-encrypted communication: SDS uses
standard AES encryption protocols. To communicate successfully, products
and applications on the peer side must use the same protocols and the same
shared key as the SDS. To ease the development process, Lantronix
provides an AES encryption DLL for Windows and protocol source code
samples. See the document “Encryption Enabling Serial Devices” on the
Lantronix web site (
www.lantronix.com
) for more instructions and sample
code.
