With the func1on 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 posi1ons. The DR4024 also has four addi1onal switching outputs which can be used, for exam- ple, for switch polariza1on or for controlling St.
Stand 2018.10.22 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 be2er to use a switching power supply (DC) with at least 12V 2A for adjustment work and normal opera1on. You should always keep in mind that some servos have a "high"...

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 magne1c ar1cle address which the DR4024 is to receive as the start address at the central unit, handset controller, app, etc.

(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 wri2en to the DR4024 with the respec1ve func1on Write POM of the central, app or handset controller.

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.

Switch the func1on F0 (light) on and off again to ac1vate the locomo1ve in the control panel. Press the programming bu2on on the DR4024. The red LED now lights up con1nuously 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 magne1c ar1cle address 1 again. By switching the magne1c ar1cle 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.

This is absolutely necessary to successfully complete the RESET. AJer approx. 30 seconds the desired connec1on can be restored. The DR4024 is now reset to factory seBngs. The POM address was reset to 9999 again and the DR4024 has the magne1c ar1cle address 1 again. By switching the magne1c ar1cle address 1 it can be checked whether the RESET was successful.
Some central units have the problem that aJer pressing the programming bu2on of the DR4024, the red LED goes out again shortly aJer the programming mode has been ac1vated and the DR4024 automa1cally terminates the programming mode.

(this CV can only be wri2en 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 informa1on on these presets, see page 24.

This can be useful if you want to switch several outputs simultaneously via one key. If you want to switch several outputs in a group with one func on key, then add the values.
