Ripple Control

Swistra, the Ripple Control of the 21st Century

Swistra, die Tonfrequenz-Rundsteuerung des 21. Jahrhunderts.

What is Swistra?

  • Swistra is a completely new developed transmission method.
  • Swistra is an evolution for an existing Ripple Control system.
  • Swistra is a byte pattern composed of a command byte and three address bytes.
  • Swistra is backward compatible with known Ripple Control telegrams.
  • Swistra is the Ripple Control of the 21st Century.

Why switch to Swistra?

  • Swistra has higher data rate than other bit patterns.
  • Swistra has shorter telegram runtimes than other bit patterns.
  • Swistra has a very large address space.
  • Swistra can address each recipient on its serial number individually.
  • Swistra can be used without a conversion phase.

Swistra – flexible control!

With Swistra loads and generators can be controlled with a customizable group address structure, for example according to minisubs. Moreover each Swistra receiver can be controlled individually. The group assignment can be reprogrammed with a dedicated Swistra command via a Ripple Control transmission:

Swistra – how do I change?

  • Upgrade the control system. Swistec RKS-controllers only need a firmware update to achieve this.
  • Most static transmitters can be retained. Rotating transmitters need to be replaced (e.g. with a Swistec SRS-3xxx transmitter).
  • Installation of receivers for the desired new tasks.

Swistra – what remains the same?

  • Compliant and compatible with all existing Ripple Control systems / bit patterns.
  • Using the same frequency as the existing Ripple Control system.
  • Using the same coupling cells as the existing Ripple Control system.
  • Most static transmitters can be retained. Rotating transmitters need to be replaced (e.g. with a Swistec SRS-3xxx transmitter).
  • Using all existing receivers in a mixed mode.

Swistra – receivers from Swistec

All Swistec ripple control receivers use state-of-the-art, recently developed filter algorithms capable of reliably processing ripple control signals with operating voltages below 0.3% Un – a result of state-of-the-art processor technology combining high CPU power with little power consumption.
