Pushbutton interface

In addition to the manual control (module top) and the 1-wire interface, the Dual Dimmer 1 also has an 8-fold

pushbutton interface (8 x binary input) for switching and dimming the outputs.

To switch an output, a short input signal (keystroke) is sufficient, to dim a long input signal to the corresponding

input.

The inputs of the 8-fold pushbutton interface (extension inputs) are intended for switching and dimming luminaires

or luminaire groups in commercial and residential areas. The inputs are controlled with a typical 24V (10-30V) DC

voltage. Pushbuttons from any switch manufacturer can be used on the inputs. Any number of push-buttons can

be connected in parallel at each input of the push-button interface.

The direct control of the Dual Dimmer 1 via pushbutton interface ensures very fast switching and dimming

even without a Smart Home System (software).

In addition to pushbuttons, another pulse control signal can also be used to switch and dim the outputs of the

Dual Dimmer 1.

All three interfaces, module push-button, pushbutton interface and 1-wire interface, work in parallel on the

outputs. An output switched e.g. by the 1-Wire interface can be switched off or on and dimmed manually or via

pushbutton interface.

Software / Control

The 1-Wire interface of the Dual Dimmer 1 is controlled by standard commands for the DS2408 module.

The 1-Wire interface can be used to read back every keystroke as well as the dimmer values of the outputs. The

dimmer values are output alternately via the 1-wire interface. Channel 2 can be detected by bit 5 (1).

The outputs of the dual dimmer 1 are controlled as follows via the 1-wire interface by byte command:

One output can be controlled per transmitted byte value.

- Bits 0-4 corresponds to the brightness value (32 dimmer levels)

- Bit 5 is reserved, currently no function

- Bit 6 is intended for the selection of the dimmer output.

Channel 1 is addressed with a 0, channel 2 with a 1.

- Bit 7 is reserved, currently no function

11.1

Control via 1-Wire Controller / 1-Wire Gateway

The control and data output of the Dual Dimmer 1 is very simplified via the 1-Wire Controller / 1-Wire Gateway.

The current dimmer values and the status of the push-button interface are output continuously.

In the case of a control signal on the push-button interface or on the top of the module, a separate data record

with the normal formatting is output. The following control command can be used to control the dimmer value of

one output at a time. There are 32 dimmer values available per output.

11.2

Control Command for Dual Dimmer 1

One output of the Dual Dimmer 1 is controlled per command. To control the dimmer outputs, the following options

are available

32 dimmer stages (0-31) per channel available.

Command: SET,OWD,DIM,OWD-number, output, dimmer value

Example: set,owd,dim,2,1,25 => OWD number 2, output 1 is set to dimmer value 25.

After controlling the dimmer, the new dimmer value is output as confirmation.

11.3

Data Output 1-Wire Controller / 1-Wire Gateway

For the Dual Dimmer 1 the following data for push-button interface and outputs are output.

The input and output values are output as decimal values 0-254 and in a second data set binary with 0 and 1.

Each input and output has a value which is summed up.
