This guide provides step-by-step instructions for successfully using a Bring Your Own Device (BYOD) Android tablet with a 3D Earthworks machine equipped with the add-on Trimble Marine Construction system and no TD display.
1. Scope and requirements
An Earthworks TD5xx display is not usually required on a marine system since TMC is the operator interface. The EC520 Tech web interface can be used for all of the configuration tasks except:
-
Project selection
-
Uploading project files such as Designs and Site Calibration
These tasks require either a TD5xx display or a BYOD running Earthworks.
This document describes the use of a BYOD to load these files onto the EC520 for a marine project.
