3.5 DMX 512 connection
To b ild a DMX chain
1. Connect the DMX o tp t of the controller directly with the DMX inp t of the first fixt re in the DMX chain.
2. Connect the DMX o tp t of the first fixt re in the DMX chain with the DMX inp t of the next fixt re.
3. Always connect the DMX o tp t with the inp t of the next fixt re ntil all fixt res are connected.
Do not overload the link. Max. 32 fixt res may be connected on a DMX link.
Ca tion: Terminate the o tp t of the last fixt re with a 120 Ohm resistor wired betwen data (+) and data (-) in
order to ens re the proper transmission on the data link.
3.6 Master/slave connection
To b ild a master/slave-chain:
Connect the DMX o tp t of the master fixt re in the data chain with the DMX inp t of the first slave. Always
connect o tp t with the inp t of the next slave ntil all slaves are connected ( p to 32 fixt res).
Ca tion: It is necessary to terminate the inp t of the master fixt re and the o tp t of the last slave with a 120 Ohm
resistor in order to ens re the proper transmission on the data link.
3.7 Stand alone operation
The fixt res on a data link are not connected to the controller b t can exec te pre-set programs which can be
different for every fixt re. To set the program to be played, see the "Stand-alone setting" (men "St.AL.").
"Stand-alone operation" can be applied to the single fixt re or to m ltiple fixt res operating synchrono sly.
Synchrono s operation of m ltiple fixt res req ires that they m st be connected on a data link and one of them is
set as a master (master mode) and the rest as the slaves (slave mode).
To set the fixt re as the master or slave, see the " Fixt re Address " (men "A001").
Only one fixt re can be set as the master.
The master fixt re starts sim ltaneo s program start in the other slave fixt res. All fixt res have a definite,
synchronized starting point when playing back their programs. The n mber of r nning program is the same in all
slaves and depends on the master's choice (men "St.AL.“). Every fixt re r ns its program repeatedly, starting the
program step No.1 when req ested by the master.
Example:
If the slave fixt re has a shorter program length, it will contin o sly repeat its program ntil the master fixt re
finishes its own program and restarts its program r nning (slave 1- prog.step 3 will not be finished).
If the slave fixt re has a longer program length, it will restart at prog. step 1 before it completes all its prog.steps
(slave 2 - prog.step 5 will not be played)- see the pict re bellow.
ote: Disconnect the fixt res from the DMX controller before master/slave operating, otherwise data collisions
can occ r and the fixt res will not work properly!
