0-10VDC Casambi Scene Selector

Scene10cas is a Casambi “Gateway” device designed to utilize a connection to a standard 0-10VDC analog dimming master controller to provide a remote selection of pre-defined Casambi Scenes and Scene Intensity. Scene10cas is connected between a 12-24 VDC Class 2 power supply and a two-channel 0-10VDC master.

Scene10cas decodes both 0-10VDC channels and provides Scene selections by mapping the first 0-10V channel into voltage segments, which are then selected depending on the voltage level. The second 0-10VDC channel provides a 0-100% intensity selection for the selected Casambi Scene.

Voltage trim and hysteresis values are also provided to implement installations where the 0-10VDC levels may not be in full range or are noisy due to installation factors.

Scene10cas can be configured with the Casambi app which can be downloaded free of charge from the Apple App Store and Google Play Store. Different Casambi enabled products can be used from a simple single luminaire direct control to a complete and full-featured.

Scene Control/Selection

Number of Scenes – determines the voltage window range for each Scene.
For example, if 4 Scenes are desired, this sets the voltage window to 2.5V (10V/4 = 2.5V) per Scene

Connect a Class 2 power supply with 12-24 VDC output voltage to the input connector of DMXcas. Make sure not to use a constant current LED driver and make sure that the cable polarity is correct.

The product has one DMX universe, with a DMX+ and DMX– connection, plus a ground. Connect the DMX load wires accordingly.

DMXcas can be mapped just like pushbuttons are mapped in the Casambi application. Once you add the DMXcas to your Casambi network, navigate to the “More” button at the bottom of the app. Then press “Switches:, where the DMXcas will be seen. Press on the DMXcas that you want to configure, and select each of the eight pushbutton items in turn. Then configure each of the eight pushbuttons to control a Casambi element by pressing on “Not in Use” .and then select what the pushbutton is to control, most likely “Controls and Element”, which then you can select a certain element to control. Be sure to press “Done” at the top right to save the configuration.

DMXcas should not be placed in a metal enclosure, such as metal junction boxes. Metal will attenuate radio signals which are crucial to the operation of the product. If the product will have to install into a junction box, make sure to use a plastic junction box.

DMXcas is an ETL Listed Open-Type device which means that it will have to be used together with a Class 2 power supply with a maximum output power of 100 VA. The product can be installed outside of the junction box. Make sure to comply with National Electric Code in installation and when selecting installation wires.



* The relay must be protected against inductive over voltage spikes, i.e. it must have a flyback diode. Do not connect a typical PCB relay without the diode.

The range between two DMXcas or between a DMXcas and a smartphone can vary depending on obstacles and surrounding material. In open-air, the range between two DMXcas’ can be in excess of 200 ft, but if the unit is encapsulated into a metal structure, the range can be only a few feet. Therefore, thorough testing is highly suggested.

Casambi uses mesh network technology so each DMXcas acts also as a repeater. When testing the network, it is important to test that each unit can be controlled from any point of the network covered area.
