Leave it off for normal use.

Keep screen on

Prevent the device of going into sleep mode.

Module view

Switch directly to module view in case the loaded plan is modular.

Small Throttle

Option for large displays to keep the throttle dialog small.

:!: Do not use this option on small devices.

Images on demand

Load only loco images as needed to decrease communication at startup.

Sort by address

Sort loco list by address instead of ID.

Sort by category

The blue arrow represents the Loco placing.

  1. Steam
  2. Diesel
  3. Electric
  4. Trainset: Independent from engine type if commuter flag is set.
  5. Special: Cleaning or Post type.

R2R Address/Port

If a Rocrail server has R2RNet activated it will provide its client connection information by multi casting to the andRoc clients.

andRoc:  <netreq req="clientconn"/>
Rocrail: <netrsp host="" port="8051" rsp="clientconn" plan="Plan-F"/>


If Ping is activated andRoc will send every 2.5 seconds a ping to the loco controlled in the throttle.
If the ping will not come within 5 seconds the Rocrail server regarded the andRoc connection as broken and will stop the loco immediately to prevent accidents.

Guest Loco
