  • Page 3: Description

    DALI device 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.

  • Page 4: Safety Conditions

    5. All repairs and connections of outputs or DMX signal can only be made with power off. 6. PX255 should be strictly protected against contact with water and other liquids. 7. All sudden shocks – particularly dropping – should be avoided.

    “+” or “-” using the key. After that you need to save the settings before going level up, this will allow storing value in memory of the PX255. To do this, after moving to the screen button you need to push enter button.
  • Page 7 Description of information showed on Summary screen 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).

    • DMX-512 protocol mode 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.

    Programming device settings 7.1 DALI After selecting DALI sub-menu a user will see another window. Available options allow to menage all the options associated with the DALI protocol. The picture below shows the list of available options. To choose one of them you need to select appropriate option with buttons and confirm the selection by pressing enter button.

  • Page 10: Ballasts Settings

    Consecutive found ballasts are marked with lighting bulbs symbols that are visible next to the number of ballast. The ballast marked with with a question mark sign are not found by the PX255. The device supports up to 64 ballasts (according to DALI protocol specification). Only in recognized ballasts user can change parameters.

PX255 allows 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.

    (in range Adr.00 to Adr.63). The device is finding ballasts separately, and each should be addressed individual. In case you choosing Auto option, the PX255 automatically assigns the next found ballasts addresses (00 to 63). 7.1.4 Number of ballasts...

  • Page 15: Number Of Virtual Ballasts

    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 protocol the maximum number of ballasts is limited to 64. The user in this menu can further reduce the number of such ballast to zero.
  • Page 16 also possible to allocate one group to selected one DMX channel. In addition, the last option on the menu list i.e. All ballasts < DMX--- allows to set all DALI ballasts to one selected DMX channel. To change the default values follow these steps: select a specific ballast using buttons and confirm by pressing enter button.

  • Page 17: Dali>>>Dmx (Dali To Dmx) Patching

    7.3 DALI>>>DMX (DALI to DMX) patching This option allows to enter the converted brightness value of the virtual ballast onto a given DMX channel. First of all, you can change the virtual DALI ballast address with the specified number, which is assigned to the selected channel DMX.

  • Page 18: Screensaver

    We use the name “virtual ballast” due to the need of simulations by the PX255 the real ballasts. This allows the correct operation of the protocol conversion mode from DALI to DMX-512. 7.4 Screensaver In this menu it is possible to activate the screensaver mode after a time period of inactivity (not pressing any of programming button in PX255).

  • Page 19: Dmx Out Settings

    After selecting a sub-menu DMX Out Settings on the screen will show up the currently set parameters of DMX signal. This menu allow to replace the parameters of the DMX-512 signal sent from a device. Default in the PX255 are set values visible below.
  • Page 20 start data stop stop one frame 44 microseconds Because one frame contains full information about the DMX channel, to send all of 512 channels we need 512 frames. However, the receiver need to recognize when the entire transmission starts (i.e. which channel is first). That is way the transmission begins with the signal called BREAK.
  • Page 21 When you send a zero byte controller starts to send bytes with data, starting from the content of the first channel. The minimum number of channels permitted by the standard is 24 and a maximum 512. This means that even if we have a simple 6-channel lam controller, the transmitter still have to send 24 DMX channels.
  • Page 22 In the most applications a one of the first two solutions are used or the user is allowed to select the one of the options with appropriate software. Due to the lack of compliance with the DMX-512 standard of multiple devices available on the market below options allow to select appropriate parameters of the output DMX signal to a specific device.

    5. Channels number – using this feature, you can limit the number of channels sent from PX255. The minimum value is 24 channels and the maximum is 512 (default). 7.6 Input DMX preview This menu allows to check the current DMX signal received by the PX255.

  • Page 25: Language

    DMX channels are described on the left side, respectively 1, 129, 257, 385 for subsequent lines. In addition, each line is divided by dots, where red means another ten channels, and green additional 100 channels bigger value. 7.7 Language Language settings allows to change the menu language. To do this select appropriate language using buttons and press enter.

  • Page 26: Dmx Signal Connection

    PX255 have to be connected to DMX line in serial mode, with no branches on DMX control cable. That means that DMX line, from the signal source, must be connected to DMX IN pins of PX255 and later, directly from DMX OUT pins to the next device in DMX chain.
