5 – Operation
5.1 – Startup
Upon applying power, if you already have strings connected they will flash very briefly (<50mS) and
then immediately turn off as the controller takes control of the pixels. If no data is being piped
through to the controller then the pixels will remain turned off until valid data is received. During
normal operation the green power LED will remain on solid and the status LED will flash slowly to
indicate the controller is connected to a valid network and is ready to run.
5.2 - Sending Data
Data is sent from the host machine to the contr oller via the LAN using a “DMX over IP” protocol such
as sACN (E1.31) or Art-net.
5.3 – Outputs
5.3.1 – Pixel Outputs
Each of the 4 outputs can drive up to 680 individual RGB pixels (4 DMX Universes of data). This
allows for a total of 2,720 pixels to be driven out of the one controller (in addition to 1 DMX512
Universe output.) Driving a full 680 pixels out of a single output would also likely require power
injection. How much power you need to inject and how often will typically vary depending on the
number of pixels used, their voltage and their individual power consumption.
The refresh rate of the pixels will depend on the operating frequency of the specific pixel chip type.
Higher speed chips will result in higher refresh rates. PIXELS WITH NO CLOCK LINE ARE SLOW. The
refresh rates on these pixels is unavoidably slower than clocked pixels. Advatek recommends the use
of clocked pixels whenever using a large number of sequential pixels on any output. Typically, the
refresh rate can vary from 20 fps at the low end and up to 100 fps at the higher end.
5.3.2 – DMX512 Output
The PixLite 4 provides a DMX512 output which can be accessed by a pluggable screw terminal
connector. The hardware layer on which the DMX 512 protocol operates is the RS485 electrical
communications standard. This is a differential transmission system consisting of a two-wire
differential twisted pair and single wire ground connection. The D+, D- and ground connections are
clearly labelled on the PCB for the screw terminal connectors.
