  • Page 18: White Balance

    Sometimes, there can be problems with getting white colour on the RGB series LEDs. This may be a result of using diodes with different technical parameters. For this reason, the PX254 module is equipped with a white balance function. This option allows for choosing a correct colour temperature for full activation of all 3 outputs (white colour).

  • Page 19: Limiting The Output Power

    12 Limiting the output power The white balance parameter, apart from its original functionality, can also be used to limiting the output power of the driver. It works linearly and in a percentage way limits the output power of a given channel. For example, if the bLr parameter is set on 50, it means that by the DMX control and no signal mode this value can not be exceeded.

    13 Smooth The driver is equipped with a smooth option. Smooth feature allows for smooth changes in lightness and colour. When it is set to On the transition between successive DMX values sent to the lamp (e.g. corresponding to changes in lightness) are smooth with no visible twitches, which prevents the common light “vibrations”...

    ENTER ENTER 5 x NEXT ENTER NEXT NEXT PREV ENTER NEXT 14 Light control frequency The Frq function allows for setting the basic control frequency for the LEDs. This function is extremely useful in applications for the television industry. By applying the "flicker free" technology, it is possible to avoid the unpleasant flickering effect which is caused by improper signal synchronization that controls the LEDs.

    16.2 Error message The device is equipped with a built-in memory work control function. If there are problems with the memory operation on the PX254 display, the Err message appears – memory error. In this situation, select the “enter” key. The device will reload the default configuration and upload it to the memory.

  • Page 25: Dmx Signal Connecting

    PX254 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 PX254 and later, directly from DMX OUT pins to the next device in DMX chain.

  • Page 26: Rdm - Available Parameters

    19 RDM – available parameters The PX254 supports the DMX-RDM protocol. DMX protocol allows only of a one-way data transmission, while its extension the RDM protocol can transmit information in two directions. This makes possible to simultaneously send and receive information, and hence the possibility of monitoring activities of the compatible devices.
