Digitrax Command Stations
Digitrax Command Stations employ Option Switches to cutomise the operation of the command station.
The switch on the front panel must be set to OP to change option switches, with a throttle connected to the command station.

Digitrax has updated their knowledge base for these command stations:
Terminology
- Route: A specified group of turnouts which will be triggered when a command is issued by the throttle. The turnout at the TOP address controls the others to set the route.
- Aliasing: Aliasing allows operation of a locomotive with a 2 digit primary address using a 4 digit extended address. The DCS100 handles this feature not the decoder. It is no longer supported.
- Purge: A procedure in which the command station will release locomotives automatically, setting their slot of "Common" from "In–Use". This will occur if they are not under control of a throttle connected to the LocoNet when a time of approximately 200 seconds (~three minutes twenty seconds) elapses. Other operators can take control of the locomotive after purging has occurred. The DCS100 will allow this mode to be extended to 600 seconds (10 minutes) or disabled.
