7. General Information

The shutter control units DRO 4b and DRO 4c are components of the Dupline building

management system and allow switching up to four independent shutters as well as

sunblinds or electrical dormers.

These second-generation shutter control units (identified by the Up and Down arrows

printed on the front panel) are equipped with a micro-controller which ensures that even

with an incorrect channel generator configuration the required reverse idle time of

500 ms is maintained.

While the DRO 4b is designed for the 'classic' control of shutters and skylights, the

DRO 4c offers a 'Step-Mode' feature for adjusting louvered blinds or shutters with slats.

When using the latter model the option "Tilting Blinds" in the ProLine object "Roller

blind" should therefore not be activated.

Note:

Please be sure to observe the following points when using the DRO 4c:

• Not every drive is suitable for the step-mode. Therefore, operate the DRO 4c

only with those drives which - according to their manufacturer - will not be

damaged by frequent pulsing of 100 ms duration.

• Due to the wide range of different shutters and blinds perfect slat adjustment

cannot be guaranteed in every case. If in doubt check the interaction between

DRO 4c and blinds beforehand.

8. Coding

With the hand encoder DHK 1 each channel can be assigned any address between A1

and P8 using the modular plug at the front of the DRO 4. The channel allocation is as

follows:

Channel

Motor 1 UP

Motor 1 DOWN

Motor 2 UP

Motor 2 DOWN

Channels, which are not used, should not be encoded. The encoding of the DRO 4 can

be done without operating voltage and without any connection to the Dupline bus. The

encoding remains permanently but can be overwritten at any time.

The address assignment has to be done in that way, that the channels for the UP and

DOWN directions of each motor get consecutive addresses. It is always necessary to

start with an odd address.
