    12 – 48V DC power supply allows to control large amounts of LEDs supplied with 350mA current. PX745 can be controlled by the DMX signal or it can work independently. In this operation mode, the user has access to a fully programmable scene and 18 default sequences for which can also change the reproduction speed and the smoothness of transition of particular steps.

  • Page 26: Error Message

    PX745 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 PX745 and later, directly from DMX OUT pins to the next device in DMX chain.

  • Page 27: Rdm - Available Parameters

    RDM – available parameters The PX745 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.
