Comtech Python controller
The Comtech controller written in Python is developed to control the 23cm ATV Transmitter and Receiver at the same time from your PC.
To control the Transmitter and receiver via your PC you need an USB to I2C interface. In my case I used the Antratek Enhanced USB to I2C Module.
This is a high-level overview of the all the devices:
The Port Extender (PCF8574AP) is an I2C port extender with 8 ports which can be used for input and output. This is currently NOT used in the Python Controller software V1. The port extender will be used to control coax switches and relays from the Comtech Python Controller. Example is to switch the LNB between Horizontal and Vertical and switch my 23 cm antenna between the transmitter and the receiver.
The latest version of the Comtech Python Controller can be downloaded at the bottom of this page! Any questions regarding this project please send me an email!
