Course 285: GEM One


This hands-on course familiarizes learners with GEM One, a remote management software used to centrally manage networked End Cryptographic Units (ECU), such as KG-175 TACLANEs and vIPers. The combination of guided exercises and performance-oriented labs gives learners practical experience that can be used on the job. In addition, this course provides guidance on how to transition from the recently discontinued GEM X to GEM One.

Target audience

Network administrators, technical authorities, Communications Security (COMSEC) custodians, local element managers, designated COMSEC authorities and contractors who maintain, handle, distribute or use TACLANE products.


It is strongly recommended that you complete the online course 780 – Introduction to in-line network encryptors and course 281 – TACLANE Network Encryptor prior to attending this course.
