Interface
Turntable Dialog Interface Tab.
Interface ID
| This must be set by all turntables in the plan if at least one of them uses the DSD2010 library. Which is needed to report the right events to the right turntable. |
If more than one command station is used, then the command station that is responsible for controlling the decoder is specified in this field. The "Interface identifier" field can remain empty if the object is connected to the first command station (first 'digint' in rocrail.ini) from the list of command stations.
Node ID
See: Addressing
Address
Depending on the type this must be a locdecoder address or a FADA accessory address. – Second address only for decodertype "AccDec".
Direction Address
Depending on the type this is the FADA accessory address for switching the rotation direction.
Addressing
Supported types:
- TTDec
- AccDec
Function
| locdec type |
Left: Decoder function output for controlling the snap-in bridge coil 1).
Right: Decoder function output for controlling the polarization relay 2). (Polarisation Address must be set to zero)
Lights
Decoder function output for bridge cabin lights. (locdec type)
Motor off delay
Number of ms. between deactivating the bridge coil and stopping the bridge motor.
Rotation Steps
Nr of steps for one 360° rotation.
Correction
Number of steps to add/subtract incase of a rotation direction change.
Use to compromise mechanical margins.
Steps delay
Size of the start and deceleration ramp.
Offset
| Type | Function |
|---|---|
| WIO | Calibration correction point in steps. (Hall sensor position.) |
| OneStep | Reported position in degrees correction. |
Start delay
Delay of max 5000ms before the command is send to the controller.
This time can be used to play sounds before the movement.
Supported types:
- WIO
Type
- muet (Müt 1740x)
- ttdec (LDT) (german)
- d15 (Draai15 by Kees Moerman.)
- dsm (Stärz)
- OneStep (OpenDCC/BiDiB)
- DSD2010 RS232 (Digital-Bahn)
- WIO (Stepmotor)
- WIOservo (Segment turntable)
Rotation speed
Specifies the rotation speed of the stage as a percentage of the maximum speed.
This percentage is used to calculate the speed level for the decoder: for example, if the decoder has 28 speed levels and 50% is set, the stage is rotated at speed 14.
Delay
Time in seconds to wait, after the bridge got into position, before starting the locomotive.
The sensor event is too early if reed relays are used.
Delay for change of direction
Time in seconds between the direction and position commands.
Protocol
| Type | Description | Command type |
|---|---|---|
| D | Command Station default | switch |
| M | Motorola | switch |
| N | NMRA DCC | switch |
| MP | Multiport | programming (LocoNet+LocoIO) |
Position Sensors
This optional sensor can be used if the turntable controller generates an event after reaching the wanted bridge position.
In this case the Track Position Sensors can be left empty.
Bridge Sensors 1 to 4
If the turntable is also to be used in automatic mode, the Bridge track must be divided into at least two occupancy reporting sections. Two Point sensors can also be used, e.g. near the ends of the Bridge track.
See also Bridge occupancy.
The two sections or the punctiform Feedback sensors positioned there are assigned to Bridge Sensors 1 and 2. The assignment is arbitrary, because the feedback that triggers first automatically generates the enter event and the feedback that triggers afterwards the in event.
The Bridge track can also be divided into three or four sections and the two Middle sections or the punctiform sensors positioned there are assigned to Bridge sensors 3 and 4. The first triggering sensor 3 or 4 generates a pre2in event, which for locs with activated option Stop at pre2in event as in event is evaluated. This allows, for example, shorter locomotives to be stopped closer to the middle of the Bridge track.

External Bridge Block
The Optional: external Bridge block setup is required in the following cases:
- The assignment of the events to the sensors should be done differently than described here for sensors 1 to 4.
- The bridge is only operated with one Track section and needs e.g. an enter2in event to stop locomotives safe on the Bridge.
- The representation of the Turntable block is desired as it is done with normal blocks. (Colored status display, locomotive image, etc.)
Further details, as well as creating and setting up the external Bridge block, are described in a chapter on the page Turntable: Setup.
Bridge Polarisation.
Depending on the used hardware one or two addresses or outputs can be used.
Polarisation has to be set for every turntable track; See Track setup.
Not used if left to zero.
Address
Address(es) for controlling a bistable bridge polarisation relay.
Output
Output(s) for controlling a bistable bridge polarisation relay.
Rotation velocity
Specify the bridge rotation velocity in percents using a locdec type.
This percentage is for calculating the speed steps for the decoder: if the decoder has 28 steps and this value is 50% step 14 will be used.
Direction change pause
Time in seconds between direction and position command.
For DigitalBahn decoder only; at least 2 seconds are recommended.
Options
Invert
Must be set for TT-DEC in combination with Xpressnet and RocoNet.
Swap rotation direction
Rocrail calculates the rotation direction to get the shortest way to a track. But if the used decoder seems to do the opposite it can be swapped using this option.
Skip command if already set
Skip a goto track command if the bridge is already in this position.
