[. . . ] Merger: DMX-signals from 2 different controllers can be combined and send over 1 cable, you can choose the start address of the second controller. The splitter function distributes the DMX-signal(s) from the input(s) over 6 identical outputs that are 100% isolated from each other: problems that occur on 1 output will not influence the other outputs!The timing of the DMX-outputs can be adapted from 23ms to 45ms, increasing compatibility while connecting "slow" DMX-devices to "fast" DMX-controllers. Output behavior can be selected when suddenly both DMX-inputs fail: Null: no DMX signal on the outputs Hold: keep the last DMX values on the outputs. [. . . ] The socket inlet shall remain operable for disconnection from the mains. The power cord should always be in perfect condition: switch the unit immediately off when the power cord is squashed or damaged. It must be replaced by the manufacturer, its service agent or similarly qualified persons in order to avoid a hazard Never let the power-cord come into contact with other cables!This appliance must be earthed to in order comply with safety regulations. Always replace a damaged fuse with a fuse of the same type and electrical specifications!In the event of serious operating problems, stop using the appliance and contact your dealer immediately. Due to safety reasons it is prohibited to make unauthorized modifications to the unit. Check the contents: Check that the carton contains the following items: DMS26 DMX merger/splitter unit User manual Some important instructions: Before you start using this unit, please check if there's no transportation damage. Should there be any, do not use the device and consult your dealer first. Important: This device left our factory in perfect condition and well packaged. It is absolutely necessary for the user to strictly follow the safety instructions and warnings in this user manual. The dealer will not accept responsibility for any resulting defects or problems caused by disregarding this user manual. To protect the environment, please try to recycle the packing material as much as possible. Do not use volatile liquids such as benzene or thinner which will damage the unit. If, for any reason, controller A fails, controller B (the backup controller) takes over immediately. On the A/B INPUT LEDs (6) you can always check which controller is in command!When both controllers fail, you can decide how the outputs should react: see "NO INPUT option" below. MODE MENU MERGER OPTION Normally you can't make 2 DMX-controllers work together on 1 DMX-line: both controllers send out the same channels and signals would crash. This is the solution: in MERGER-mode ("MErg" + start address controller B alternate on the display) you can connect two controllers to the inputs A and B (7/8) and make them work together on 1 single DMXcable. The controller connected to input A (7) is the first controller, starting from DMX address 001. For the controller connected to input B (8) you can freely set the DMX start address (see "Addr option" below) Example: Controller A is a 24channel DMX-controller for Theater lighting. Both controllers can work together on 1 DMXcable, just set the start address for controller B to 025 and add 25 to the original DMX-channels of the scanner controller: original DMX-address 001 becomes 025, original DMX-address 130 becomes 155 (130+025) ADDR OPTION Will only be used in MERGER mode to set the start address of the controller connected to input B (8). [. . . ] mODE MENU HTP OPTION In HTP-mode (Highest Takes Precedence) two controllers will be connected to the inputs A and B (7/8). Both controllers work simultaneously so both A/B INPUT (6) indicators are lit. The DMX-values of both controllers are sent to the outputs but for corresponding channels, the channel with the highest value will be routed to the outputs. Some low cost Chinese DMX-equipment is not able to work at these high refresh rates, as a result data is lost and all kinds of unpredictable behavior occurs. [. . . ]
