Terms

  • Dispatching -Dispatching is the process of releasing a loco so that another user can take control of it.
  • Stealing - Stealing is defined as acquiring control of a loco address that is being used by someone else on another throttle. Both throttles control the address. Useful for training operators.

StealZap

This applies to the DT402 R2 advanced throttle when used with an Advanced command station (DCS240) featuring expanded slots. This feature works when each DT402 R2 in use has a unique throttle ID, and they are operating in the expanded slots. The throttle ID is associated with the locomotive address it has selected. If all throttles have the same ID, the Steal function works as before and both throttles have control of the locomotive.

The StealZap feature prevents multiple throttles from having the same address selected. When a locomotive address is entered into a second throttle, the message "StealZap" appears on the first throttle. This means the address has be deselected because that locomotive has been stolen by another throttle. The original throttle can steal the locomotive back by selecting that address again.

This prevents confusion and unexpected results which occur when two throttles have control of one locomotive.
