Serialization is a method to extract data from the various sensors in TPT and output it over FILT. 

LSNS (life sensor), TSNS (temperature sensor), and PSNS (pressure sensor) can all be allowed to serialize what they sense by changing their .TMP property to 1.

There's also a way to deserialize data, too. Deserialization is how you convert data fron FILT to various properties of the simulation. Attaching HSWC (to deserialize TSNS to temperature), PUMP (to deserialize PSNS to pressue), and LSNS (to deserialize LSNS to life) to FILT allows you to output pressure, life, and temperature over long distances.

To deserialize, each element used to deserialize must have their .TMP set to 1.

Here's a good save that demonstrates serialization:
