DMX512 / MIDI / ASCII -> Demultiplexer for 12 analog channels and extensions
The DAC12A is the successor version of the DAC8. It is of the same size, but disposes of 12 analog 10V-outputs with an output voltage of 55mA individual load and 75mA total load. Serial number 02.048 and above have a total load of up to 100mA. Not only does it support the DMX512 protocol, but also the MIDI and RS232/422 interfaces. The plug-in of additional extension cards on the SPI port CN2 enables the installation and mixing of 192 digital / switch channels (96 channels with MIDI). Theoretically, the maximum number of channels can be reached upon adding further extension cards.
The DAC12A with its integrated power supply unit and supply filter is installed on a PC-board sized only 100 x 80mm. The code switches enable the setting of the DMX start addresses and to select one of the various operation modes like DMX, MIDI, ASCII and manual test modes. A ribbon cable enables the connection of external rotary switches or dual push-button code-switches.
Adapter PC-boards are available for the electronically correct installation of the implemented protocols MIDI and RS232/422.
Upon your request, we create individual solutions for digital extension cards, interfaces and protocols.
The main operation functions can be selected directly via jumper:
|J1||HOLD VALUES or BLACK ALL in case of DMX512 failure|
|J2||selectable output curve, linear or logarithmic (i.e. control of fluorescent lights)|
|J3||5s 100% after activation for the premature ignition of electronic ballasts at low environmental temperatures|
|J4||determines minimum output voltage (factory setting 1V)|
|J5||enables the byte- or bit-mode control of extension outputs|
