HOWTO Build the Diagrams

This is how to build the diagram from YAML source with wireviz.

Install wireviz

Thusly

sudo apt install python3-virtualenv python3-pip graphviz

git clone https://github.com/formatc1702/WireViz
cd WireViz
virtualenv -p python3 env
source env/bin/activate
pip install --upgrade pip
pip install -r requirements.txt
pip install .

Usage

Thus:

wireviz harness-controller-az.yml
wireviz harness-controller-el.yml
wireviz harness-rotator-az.yml
wireviz harness-rotator-el.yml

TODO

Redesign thusly.

Mini BoM:

• Alfa Spid RAS Rotator
• Green Heron RT-21 Az/El Rotator Controller https://www.greenheronengineering.com/product/model-rt-21azel-rotator-controller-az-el/
• Disconnect Set, 4 pole. Quantity eight needed for quick disconnects on each end. https://www.greenheronengineering.com/product/disconnect-set/
• Rotator - Rotator Controller wire. Rotator Cable, Direct-Bury, UV Resistant PE Jacket, 3 ea 18 AWG Foil Shield, 2 ea. 12 AWG, Rotor Wire, Per Foot. DX Engineering CW1812OR Heavy-Duty Spec Rotator Cable DXE-CW1812OR. https://www.dxengineering.com/parts/dxe-cw1812or

This setup will have quick disconnects on each cable, at each end. List of 4-wire quick disconnects, for a total of eight quick disconnects per deployment.

• Rotator Az.
• Rotator El.
• Main Az cable. Two total, one each end.
• Main El cable. Two total, one each end.
• Rotator Controller Az.
• Rotator Controller El.

List of Harnesses:

• Rotator Az Harness.
• Rotator El Harness.
• Main Az Cable Harness.
• Main El Cable Harness.
• Rotator Controller Az Harness.
• Rotator Controller El Harness.

There are two main cable runs:

• Rotator Az Harness to Main Az Cable Harness to Rotator Controller Az Harness.
• Rotator El Harness to Main El Cable Harness to Rotator Controller El Harness.

Redo Harness, All Quick disconnects.
