    DMX LUX 12 Channel PowerLED Driver

    The DMX-12 Luxeon board is designed to work with Constant Current Power LED systems. It is a compact 12 channel, 4xRGB led control system. As Standard it works with regulated switch mode 24Vdc power inputs, and drives a constant current through a dimming control system.

    MODES | DMX 12

    A. interface Protocols
    DMX512: RS485 standard at 250kbps. 8 Data bits, 1 Start bit, 2 Stop bits.

    B. RS232: RS232 standard at 19.2kbps. 8 Data bits, 1 Start bit, 1 Stop bit, no Parity.

    C. USB

    A.USITT DMX512 / 1990 (4µSec) This is an industry standard interface used widely for the control of lighting dimmers. The DMX-9 board is also capable of handling the older version of DMX512 having a 4µ Second ‘Mark After Break’ with no change of setting. Using dip switches, the user can select a start address anywhere between 0 and 511. The user is also able to terminate the DMX512 chain by simply flicking a dip switch – no need for a terminator plug. The integral DMX512 interface includes isolation from the rest of the circuit and mains earth to avoid earth problems.

    B. RS232 Interface (Optional Extra) This interface can connect directly to a PC or MAC with an RS232 (serial) port. All the functions DMX can offer are available through this interface along with a few extras. This allows for custom PC or MAC software to be written to perform the required functions, without the expense of a DMX controller. Alternatively an embedded system could also take control of the board.

    > In-built Stand Alone Functions By setting high unused DMX addresses, stand-along programs are activated. These programs do not require any external controller and free run from the point of switch on. Also diagnostic functions are available to help quickly solve connection and other problems.

    For stand-alone operation, DMX9-27 uses following DMX address functions:  Address 511: All channels on full – useful for checking connections  Address 510: Cross fade pattern on all channels  Address 509: System check – outputs checksum on LEDs.

    DMX Settings | DMX9

    Dip Switch Configuration:
    The dip switches are located at the front of the board beside the two status LEDs. The switch is a right-angled type, so to be accessible from the outside of a casing through a cut-out window.

    The 10 dip switches provide access to all the user settings. These switches are read only on start-up, so any changes made while the board is powered will require a power down reset to take effect. Switch functions are given below:

    SW1: DMX address bit 0 [ = 1].
    SW2: DMX address bit 1 [ = 2].
    SW3: DMX address bit 2 [ = 4].
    SW4: DMX address bit 3 [ = 8].
    SW5: DMX address bit 4 [ = 16].
    SW6: DMX address bit 5 [ = 32].
    SW7: DMX address bit 6 [ = 64].
    SW8: DMX address bit 7 [ = 128].
    SW9: DMX address bit 8 [ = 256].
    SW10: DMX Terminate (on or off). Changing this switch does not require reset.

    Note: Setting a DMX start address of 0 (switches 1..9 off) is invalid for DMX and will invoke RS232 mode. Any non zero setting of Switches 1..9 will set the base address of the board for DMX mode, such that output channel 1 will respond to data at the base address, output 2 respond to data at base address +1 and so on.

    For stand-alone use the following table shows the high DMX addresses functions:

    > Address 511: All channels on full – useful for checking connections
    > Address 510: Cross fade pattern on all channels
    > Address 509: System check – outputs checksum on LEDs.
