Lg-DMX/DC

DMX-512 to DC Dimmer Module v3.0

The Lg-DMX/DC is a complete DC in to DC out dimmer module. All you need to add is a 9-24 VDC

power supply, whatever you want to control, and a source of DMX-512 to control it.

The Lg-DMX/DC can be used to control incandescent lamps, large LED arrays or DC motors. Anything

that needs a 9 to 24 volt supply that adjusts between 0 and 100% of full supply voltage.

The eight pulse width modulated outputs of the Lg-DMX/DC use high current HEXFETs. These are

conservatively rated for 5 amps of load on each output. Each output is protected by a 5 amp PTC ‘fuse’

and flyback diode.

The DMX-512 can come from a Br-Brain4, Br-ANA, Br-miniBrick8, Sd-50/8, Sd-50/8 or any other Gilderfluke & Company card which transmits animation and lighting data through DMX-512.

Each time the ‘test’ button is pressed, it advances to the next test. If DipSwitch 4 is ‘Off’, then all outputs will be turned off while any of the outputs are ‘under test’.

These are: 1) Outputs: Eight red LEDs show the status of each of the outputs. These dim and brighten as the each of the outputs is ramped up and down. 2) Test: One LED flashes whenever the Lg-DMX/DC is in one of the twelve ‘test’ modes.

This power can come from batteries or a DC power supply that is run from line current. The incandescent lamps, LEDs, motors, or whatever you are controlling also run from the same power supply.

Buffered DMX-512 Out: If DMX-512 needs to be run to additional downstream DMX-512 devices, the two standard DMX-512 connections (‘data +’ and ‘data -’) are attached to these terminals, along with (optionally) the wire shield. The DMX-512 received through the DMX-512 In/Out terminals will be buffered and retransmitted on these terminals.

You set the address by simply dialing in the DMX address of the first output to these three switches. You can use American-style (1-512) DMX addressing, or European-style (0-511) DMX-512 addressing, depending on the state of Dipswitch #7.
