Rev.1.0.

DMX-DALI-DMX Interface is a powerful device that allows to combine dynamic
light systems based on the DALI protocol and systems using DMX-512 signal. It allows
to connect DMX-512 devices in the DALI protocol, or to connect DALI devices operating
in the protocol DMX-512 standard. According to DALI specification, the PX255 can
control up to 64 DALI devices (such as ballasts). A menu of the PX255 allows to address
individual lamps or groups of devices, user can create up to 16 groups.
Additionally, for each of the lamp (ballast), you can define a number of individual
parameters such as minimum and maximum brightness of the lamp, the time at which
the brightness of the lamp reaches its maximum value ("fade time"), the number of
steps needed to achieve the maximum level of brightness ("fade rate") or determine the
brightness of each lamp in the event of failure of the control system.
The device is powered from 24V DC and manufactured in a housing of six
individual rail modules width adapted for mounting on 35 mm wide DIN rails.

Description of information showed on window:
! view of a display on the left side (DALI to DMX mode): white bars correspond to the
values of virtual ballast brightness transmitted onto the DMX-512 protocol. Height of
bars represents the value of the DMX signal on each channel (full height is 255, no bar
means 0). The display above shows the maximum of 64
channels .
! ( ): red boxes show the present
value of the converted from DMX signal and sent to a specific address of DALI
ballast. This address can be read from a visualization on the screen. It is the sum of
the visible at the beginning of each row and column.
Red bars indicates no conversion of DMX signal to individual control onto precise
address. Green fields describe converted values of DMX-512 signal send to chosen
group (between 1-16), blue fields shows value send to all of ballasts.

When the PX255 is working in mode DALI to DMX-512 signal conversion it simulates
the work of ballast (virtual ballast) allowing to any DALI controller identification of
devices on the DALI line, thus sending messages to the busbar.
In the case of working mode DMX-512 to DALI the PX255 transmits the processed
DMX signal directly to the DALI protocol.
6. MAIN MENU
At the bottom of the summary screen a Menu screenbutton is placed. Once approved,
with the enter button, the user is transferred to the Main Menu screen. This menu allows
to configure all of devices' parameters according to user needs. The following picture
shows the list of available options.
To select one of them use or buttons and then choose an option and confirm
the selection by pressing enter.

Remarks:
Ballast - is a device plugged in to the DALI bus. Typically, this is part of the lamp, but it
may also be other DALI device.
DALI interface protocol is relatively slow compared to the DMX protocol, because of
that in large installations to optimize it is recommended:
! Limit the number of ballast (7.1.4. ) to the actual number of lamps in the system;
! Group ballast;
! Delete redundant address groups.

7.1.1. Ballasts settings

!Minimal level - range: 0-254;
The lowest level of the brightness of the lamp:
0 - light is off; 254 - full brightness (100%);
When this parameter is set to a relatively high level,the DMX control will respond during
reducing of the modulation only to this value. After crossing of minimal level the further
reduction will not affect the behavior of the lamp.
If DMX signal would be set to 0 lamp would turn off every time, no matter how high the
level of the minimum brightness of the lamp will be set.
!Maximal level - range: 0-254;
The highest level of brightness of the lamp:
0 - light is off; 254 - full brightness (100%);
!Group 1-16 - Range: 0-1
Allocation of the ballast to a specific group:
0 - indicates no assignment, 1 - selected ballast belongs to the group;
!Scene 1-16 - range: 0-255;
The change of the brightness of the lamp for the specified scene:
0-254 - the bright. level of the scene 255 - the scene is not set
Scenes are parameterized for each ballast separately by DALI controller. PX255 allows
you to make changes in the brightness of the scene set in the ballast. You can not select
which scene will be switched on by the controller.
Ballast communication - values: Yes | No;
This indicates that the lamp responds to messages.
Ballast fail - values: Yes | No;
This indicates that the lamp reports an error.
Power On Event - values: Yes | No;

7.1.4. Number of ballasts
The maximum amount of ballast supported with DALI protocol is limited to 64, but to
make it easier to program and optimize the performance we recommend to set only the
required amount of ballast available in the DALI system.
To change the amount of ballast after entrering to Number of ballasts you need to select
the or screenbutton using or buttons. Then press r to set the reference
value.

7.1.5. Number of virtual ballasts
This menu is responsible for the amount of simulated virtual ballast by PX255. This
parameter is important for devices operating in DALI to DMX-512 protocol conversion
mode. According DALI protocole the maximum number of ballasts is limited to 64. The
user in this menu can further reduce the number of such ballast to zero.
To change the parameters, proceed similarly as in the previous paragraph.
