Before the official JANUS promulgation in March 2017, CMRE released two sample JANUS implementations (JANUS Toolkit) to enable the community a faster/easier way to test the proposed robust underwater digital signaling standard. The JANUS Toolkit provided a "C" programming language implementation and a Mathworks Matlab implementation. There is also a usage Manual, somewhat dated (a new version will be released soon) but still serves the purpose of providing step by step guidance to new users that are getting acquainted with the implementation of JANUS.
