PresetName

From Data Realms Wiki

The PresetName is the name that identifies an object. For example, a guns PresetName may be "Assault Rifle", so whenever the weapon is shown in-game it will be called "Assault Rifle".

In modding, lets say for the weapon above, it would be as follows:

AddDevice = HDFirearm
	PresetName = Assault Rile
	Description = Decent gun with moderate rate of fire and damage.

As you can see, the device is a weapon, and its name is 'Assault Rifle'.
