6. MASTER / SLAVE FUNCTION
The PX282 module has a built-in DMX-512 receiver and can be controlled from any desktop or
controller running in this standard. Moreover, it is equipped with a programmable function of
response to no DMX signal (
noS
). With 18 built-in default programs, it is possible to obtain
interesting effects without an external controller. However, in larger installations, several PX282
drivers implementing the same program cannot provide a full playback synchronisation.
Therefore, PX282 has a MASTER feature. When it is activated, the module changes from a DMX
receiver into a transmitter of this signal and sends programs to the other modules (which are set
as SLAVE). With this solution, it is possible to make a precise synchronization even in very large
installations.

In case when MASTER feature is active dot in the lower right corner starts to blink with 0,25 Hz
frequency. When the PX282 is receiving DMX-512 signal it starts to blink with 2-times bigger
frequency (0,5 Hz).
NOTE:
PX282 sends basically 3 channels - R, G , B, respectively, but because the DMX standard
specifies the number of channels being sent to a minimum of 24, these 3 basic channels are
replicated eight times; if need arises, it is possible to replicate them on 512 channels (not
recommended due to lower transmission rate).
5. DMX ADDRESS SETTING
The menu of the PX282 driver allows for setting the DMX address within a range between 1 and
506-511 depending on work mode of device. For example in RGB mode it occupies three
consecutive DMX addresses. If start address is set to 510, the last channel is occupied by
address 512.
To set the DMX address:
1. Set the
Adr
. function.
2. Use the "next" or "previous" buttons to set the selected DMX address.
