A word on termination: DMX is a resilient communication protocol,
however errors still occasionally occur. Termination reduces signal errors, and therefore best
practices include use of a
terminator
in all circumstances. If you are experiencing problems with
erratic fixture behavior, especially over long signal cable runs, a terminator may help improve
performance.
To build your own DMX Terminator: Obtain a 120-ohm, 1/4-watt
resistor, and wire it between pins 2&3 of the last fixture. They are also readily available from
specialty retailers.
Master and slave: select one machine as master, press the menu to choose the
function you want. Press other machines' address to be DMX state. Use signal
cable to connect machines one by one. Then slave machines will run the same as
master machine.
Use controller to control lot of machines: if all machines are set the same menu
data, or different manual data, after use signal cable to connect to controller, all
machines will be controlled by controller. (before connect to controller, all
machines should be in the same channel mode 9ch or 4ch).
