For versions 2.3 and 3.0 of PC-DMIS, the ToolChangerType entry should be set to TP200 if you are using a TP200 probe with the DEA interface, regardless of whether or not the probe changer is actually being used. If you are not using the probe changer, you do not need to do the rest of the usual probe changer setup.
For version 3.1 and later, this setup is not necessary. The presence of a TP200 is automatically determined based on the components that you select when you build the probe in PC-DMIS.
On startup, the DEA interface enables the TP200 filter in the controller if you are using a TP200.
