  • Page 4: Product Overview

    With the func3on mapping via CV programming it is possible to realize all imaginable tasks. The DR4024 is a servo decoder with four servo outputs. Each servo output can be programmed to move to four different posi3ons. The DR4024 also has four addi3onal switching outputs which can be used, for exam- ple, for switch polariza3on or for controlling St.

  • Page 6 Stand 2019-07-10 3.0 Programming If the power input and the signal input of the DR4024 are connected to each other and are connected to the siding of the control unit, the control unit may shut down due to overload. It is be4er to use a switching power supply (DC) with at least 12V 2A for adjustment work and normal opera3on. You should always keep in mind that some servos have a "high"...
  • Page 7 The turnout addresses are always assigned by a turnout command!!! Make sure the DR4024 is powered from the decoder's power connector. It is best to use a switching power supply with at least 12V DC output voltage and 2A output power. The signal connec on of the decoder must be connected to the main track output of your control panel! Call up the desired magne3c ar3cle address which the DR4024 is to receive as the start address at the central unit, handset controller, app, etc.
  • Page 8 Stand 2019-07-10 3.2 Programming the servo posi ons A-D Make sure the DR4024 is powered from the decoder's power connector. It is best to use a switching power supply with at least 12V DC output voltage and 2A output power.
  • Page 9 (For further informa on on CV byte or CV bit programming, please refer to the opera ng instruc ons of your control panel) Now the desired CV value can be wri4en to the DR4024 with the respec3ve func3on Write POM of the central, app or handset controller.
  • Page 10 Please note that reading out and programming the DR4024 via the programming track only works if the central unit does not switch off the programming track! Therefore, before a;emp ng programming, check that the green LED next to the power connector is lit. Only if this is the case can the DR4024 be successfully programmed as described in this sec on.
  • Page 11 Switch the func3on F0 (light) on and off again to ac3vate the locomo3ve in the control panel. Press the programming bu4on on the DR4024. The red LED now lights up con3nuously and indicates that the DR4024 is in "programming mode".
  • Page 12 Wait approx. 30 seconds before powering the DR4024 again and restoring the siding. The DR4024 is now reset to factory seBngs. The POM address was reset to 9999 again and the DR4024 has the magne3c ar3cle address 1 again. By switching the magne3c ar3cle address 1 it can be checked whether the RESET was successful.
  • Page 13 LED next to the power connector of the DR4024 indicates whether the programming track always outputs voltage. If this does not light up con nuously, the programming track is switched off. This leads to the DR4024 requiring a different programming or reseDng procedure than usual.
  • Page 14 This is absolutely necessary to successfully complete the RESET. AJer approx. 30 seconds the desired connec3on can be restored. The DR4024 is now reset to factory seBngs. The POM address was reset to 9999 again and the DR4024 has the magne3c ar3cle address 1 again. By switching the magne3c ar3cle address 1 it can be checked whether the RESET was successful.
  • Page 15 Some central units have the problem that aJer pressing the programming bu4on of the DR4024, the red LED goes out again shortly aJer the programming mode has been ac3vated and the DR4024 automa3cally terminates the programming mode.

  • Page 20 (this CV can only be wri4en a read out is not possible!) The DR4024 servo decoder has four presets to make programming easier. Each preset configures the DR4020 so that you do not have to change CVs manually. For detailed informa3on on these presets, see page 24.
