Unity Platform

Pegasus Astro Unity Platform is our new all around application. Our goal is to provide a robust and modern application that will support current and future products under one roof.

Unity Platform consists of the three following components.
(All components are included in the Unity setup and automatically installed to your system)

  • Pegasus Server
  • Unity Frontend (UI)
  • ASCOM drivers

The Pegasus Astro Server

Runs in the system background (Peg.Server) and is responsible for the device discovery and comunication.
The Peg.Server runs every time you launch the Unity Frontend or any ASCOM driver and automatically shuts down, after 5 seconds of inactivity, when there is no client connected into it.

(If you are a developer you can see all available methods from json rest api. Browse to Unity -> Configuration -> Api Docs

The Unity Frontend

This is the software interface (image below) you actually see and interact with each Pegasus Astro product.

A wide range of ASCOM drivers

ASCOM drivers require the latest ASCOM 6.6 to fully explore all new developed features. Please make sure that you have the latest ASCOM (>= 6.6).
If you encounter issues in ASCOM drivers please upgrade ASCOM and reinstall Unity Platform to re-register all available ASCOM drivers.

Here is an example from N.I.N.A. listing all available Unity Focuser drivers for Pegasus Astro products.

By the time you use each ASCOM Unity driver, the server automatically runs in the background and continously tries to discover any Pegasus Astro devices plugged into your computer.

It is not required to have Unity Frontend running when you use the ASCOM drivers. However if you do so, it does not harm the operation and control of any Pegasus Astro devices. Server can simultaneously handle multiple clients: ASCOM drivers or Unity Frontend is such a client.

Important Notes

  • Pegasus Astro devices use a USB to Serial communication channel. This kind of COM channel allows only one connection between your PC (e.g. Windows OS) and the Pegasus Astro device itself.
    When Pegasus Server runs in the background, communication channel is established and server acts as a hub between multiple clients (ASCOM, Unity Frontend or any other third party software that uses the server (API).
  • If you use our older (prior to Unity) Pegasus standalone software, make sure that you are not utilizing this COM port by the time you open Unity. Unity will fail to discover your device if this channel is already used.
  • Older Pegasus ASCOM drivers are not required when you use Unity. Unity has its own ASCOM drivers.
  • If you cannot connect to the device, you might have to “End Task” of the Peg.Server from Windows Task Manager. Although, this is not something that is required. Server automatically shuts down when there is no client left.

How to use one of these ASCOM drivers

Let’s suppose you have the Ultimate Powerbox v2 and you would like to drive the embedded motor controller by using the Pegasus Unity ASCOM driver in your imaging software. In this example, we’ll use N.I.N.A.

  • Locate the Focuser section and click the drop-down list.
  • Select “PegasusAstro UPBv2”.

If it is the first time that you use this driver, you have to select your device. Click ASCOM settings.

Select the discovered device tile (in this example it is the Ultimate Powerbox v2)

Click connect button. ASCOM should connect to device and you will be able to control the focuser

Uninstall

A Unity Platform uninstall removes all of these three components. Unity Frontend, Server and all Pegasus Unity ASCOM drivers.
