[chbot] RS232 FILTER

[Tokala]

Maybe look at RS485. It is less susceptible to noise as it uses the difference in the voltage over the cable e.i. it moves with the noise.

RS485 is the industry standard for low speed comms in noise environments.

Turing some things on or welding etc. It is 40 years old so the internal caps may be a bit dogy. I was wondering where I could find a filter off the shelf (too many other projects to make new) that I can put in the line. Maybe something I can easily modify. It only works at 9600 baud so low bandwidth.
