First Steps With TC310

In this article will detail how to configure the OS and make a sample request to the module to get module status information in order to validate the system setup

The demo we we use Python to send a serial request string to the TCM310 module, please ensure there are no active TCM outstations transmitting else the demo code will not run correctly.

Start by installing the necessary python serial module

We can test the module is installed correctly by running the below:

root@raspberrypi:~# python3 -m
4 ports found

Next download the file from the link below, and run it against the attached serial port

root@raspberrypi:~# chmod +x ./
root@raspberrypi:~# ./ ttyUSB0
