1 Introduction
1.1 Design
Design Tool
The GTT Design software, available at
http://matrixorbital.ca/gtt-software,
makes development for the
GTT quick and easy, while still maintaining beautiful user interfaces and menu structures. Simulating the
GTT display that is being used, the GTT Design Software allows users to place buttons, shapes, images,
graphs and text exactly where they want on screen. With its intuitive design, users will be able to create
and deploy multiple screens to be used on their GTT.
Figure 1: GTT Design Software
As shown above, the simple and intuitive design of the GTT Design tool provides users the ability to drag
objects onto their simulated GTT screen. Once placed on screen, the user will be able to re-size, and re-
position the object to their liking. The properties tab offers more precision when making adjustments to
an object, and allows a user to change a plethora of other parameters of the object selected.
Loaded with the full library of GTT series commands, the GTT Design Software also provides users the
ability to create scripts that can be loaded on the GTT. Furthermore, scripts can be linked to buttons
created by the designer, and can be executed whenever the button is pressed.
Connections
In order to communicate with the GTT, you will need to connect to the appropriate communication
header. From the factory, a standard GTT unit will come with RS232 selected as the communication
protocol. If a different communication protocol is preferred over the standard RS232 protocol, the
protocol select jumpers will have to be relocated in order to allow proper communication to the GTT.
Header locations for each available protocol can be found in your respective GTT Hardware manual. GTT
hardware manuals can be found at
http://matrixorbital.ca/manuals/gtt-series.
