LED Pixel Constraints
NDBs can drive a limited number of LED pixels. This limitation depends on a
number of factors. Be aware of your system’s limitations while you install.
NDB Data Limitations
Due to data limitations, NDBs can control an absolute maximum of 1000 LED pixels.
NDB Port Limits
NDP Ports have a maximum number of lights that they can support. If your NDB is in
16-Port mode, as it comes from the factory, it can support a maximum of 230 pixels
per port. If it is in 8-port mode, it can support a maximum of 460 LED pixels per port.
Voltage Drop
Due to the voltage drop along a strand of LED pixels, the maximum length of a run
of LED pixels is governed by its length, or by its number of LED pixels, whichever
comes first. The maximum number of LED pixels is 80 pixels / 80ft for Triklit style
fixtures, or 100 pixels / 100ft for all other fixtures. These runs can be extended
using Power Top-Ups to achieve the maximum lights per port specified under the
previous heading. Keep in mind that if you are installing a leader cable run longer
than 15’, you will need to make use of a send/receive pair and a 4-pin leader cable
to avoid data degradation.
Caution:
Make sure your power supply output voltage matches the voltage required by
your LED pixels.
