  • Page 6: Part One - Introduction

    Our systems combine two components: First, a glider computer (LX Zeus) which is used for calculating and displaying all of the key information used by pilots. This glider computer is the brain of the operation. The second part of the system is a variometer (Eos, Helios, and Era). Its job is to gather the information which the Zeus uses.

  • Page 7: Operation

    There are two ways of transferring files: either via USB or via SD port. A standard USB-A female port is available on each device (on Zeus 2.8 slim USB keys should be used). The port is exclusively used for data transfer and firmware updates.

  • Page 8: Installation Procedure (Lx Zeus And Eos/Era)

    Every unit (except the 2.8 inch, which fits an 80mm instrument hole) is supplied with a carbon which makes it possible to make the LX Zeus cut out by hand. If a CNC solution is planned, then please ask for .dwg file.
