Warnings IMPORTANT: The manufacturer will not accept liability for any resulting damages caused by the non-observance of this manual or any unauthorised modification to the equipment. • Never let the power-cable come into contact with other cables. Handle the power-cable and all mains voltage connections with particular caution! • Never remove warning or informative labels from the equipment. • Do not open the equipment and do not modify the equipment. • Do not switch the equipment on and off in short intervals, as this will reduce the system’s life. • Only use the equipment indoors. • Do not expose to flammable sources, liquids or gases. • Always disconnect the power from the mains when equipment is not in use or before cleaning! Only handle the power-cable by the plug. Never pull out the plug by pulling the power-cable. • Make sure that the available voltage is between 220v/240v. • Make sure that the power-cable is never crimped or damaged. Check the equipment and the power-cable periodically. • If the equipment is dropped or damaged, disconnect the mains power supply immediately.

When DMX inputs “A” and “B” have a present signal, both of the DMX input LEDs will illuminate. To turn the unit On or Off, use the Power switch on front panel of the unit. Connect your lighting controllers into the 3-pin or 5-pin male XLR sockets.

Operations HTP Mode To set the unit into the HTP (Highest Take Priority) mode, set dip switch 1 and 2 to the “ON” position. When two DMX signals are present, the higher DMX values for each channels (1-512) will take place. This may allow for some channels of DMX input “A” controller to be active and other channels from DMX input “B” controller to be active. Back Up and Latest Takes Priority (LTP) Mode To set the unit into the Back up/LTP mode, set dip switch 1 and 2 to the “OFF” position. The unit will now be in the Back up/LTP mode. When DMX signal “A” is present, it will take the DMX output priority. When DMX signal “A” is lost, the DMX signal “B” will take over the Priority. Merge Mode To set the unit into Merge mode, set dip switches 1 to “ON” and 2 to the “OFF” position. The unit will now be in the merge mode. You can merge both “A” and “B” signal into a one DMX output. You must set the starting DMX address for the controller that is connected to input “B” with dip switches 1-9. Note: If you set dip switch 1 to “ON” and all others to the “OFF” position, all DMX channel output will start with the first channel of DMX signal “B”.
DMX Operation DMX-512: • DMX (Digital Multiplex) is a universal protocol used as a form of communication between intelligent fixtures and controllers. A DMX controller sends DMX data instructions form the controller to the fixture. DMX data is sent as serial data that travels from fixture to fixture via the DATA “IN” and DATA “OUT” XLR terminals located on all DMX fixtures (most controllers only have a data “out” terminal). DMX Linking: • DMX is a language allowing all makes and models of different manufactures to be linked together and operate from a single controller, as long as all fixtures and the controller are DMX compliant. To ensure proper DMX data transmission, when using several DMX fixtures try to use the shortest cable path possible. The order in which fixtures are connected in a DMX line does not influence the DMX addressing. For example; a fixture assigned to a DMX address of 1 may be placed anywhere in a DMX line, at the beginning, at the end, or anywhere in the middle. When a fixture is assigned a DMX address of 1, the DMX controller knows to send DATA assigned to address 1 to that unit, no matter where it is located in the DMX chain. Figure 1 Also remember that DMX cable must be daisy chained and cannot be split. User manual...

DMX Operation Notice: • Be sure to follow figures 2 & 3 when making your own cables. Do not connect the cable’s shield conductor to the ground lug or allow the shield conductor to come in contact with the XLR’s outer casing. Grounding the shield could cause a short circuit and erratic behaviour. Special Note: Line termination: • When longer runs of cable are used, you may need to use a terminator on the last unit to avoid erratic behaviour. Termination reduces signal transmission problems and interferance. it is always advisable to connect a DMX terminal, (resistance 120 Ohm 1/4 W) between pin 2 (DMX-) and pin 3 (DMX+) of the last fixture. Using a cable terminator (part number CABL90) will decrease the possibilities of erratic behaviour.
