Description
Null Pixel Buffer
Universal buffer as an alternative to using a standard pixel as a null pixel to add additional distance between pixel elements.
The null pixel buffer should be mounted at the source end of the pixel data. Depending on the source type (controller or pixel) the distance should be from right at the source up to a max of around 10m if coming from a pixel controller.
Can be used with 5V to 24V pixels and all pixel protocols. Only 1 data line is buffered so 2 null pixels are required if being used for 4 wire pixel protocols.
There are multiple connection options and relatively large (1mm2) cable can be used comfortably.
The pads are labelled with Din, Dout, – and + on the front of the pcb.
The pads are labelled with I, O and 2 by – and 2 by + on the rear of the pcb.
The centre row of the pads is 0V/-.
The + connection should be either 5V DC or 12V DC. Failing to supply a reliable voltage of 5V or higher may produce inconsistent results.
NOTE: The Null Pixel Buffer now supports up to 24V power voltages
The above 2 images show the front and rear view of a ‘standard’ wiring to a Null.
The wires can be wired flat onto the 3 pairs of pads in the centre of the pcb or they can be wired to the strain relief pads/holes.
The Null Pixel Buffer provides the same function as the uAmp and F-Amp which are made by other suppliers. In all 3 cases the buffer function does not need to be configured as a null in the sequencer or pixel controller.

When ordered in multiples of 21 it will usually be supplied as a panel of 21 boards which a v-scored and can be snapped apart by hand.

For extending distance between pixels:
Controller ->—–3-10m—–>-Pixel String->—up to 3m cable—>-Pixel String
Controller ->—–3-10m—–>-Pixel String->—up to 3m cable—>-“Null buffer”->—–up to 30m cable—–>-Pixel String
Controller ->—–3-10m—–>-Pixel String->—up to 3m cable—>-“Null buffer”->—–up to 30m cable—–>-“Null buffer”->—–up to 30m cable—–>-Pixel String
Note: the distances shown are approximations. Your actual distance will vary depending on the type and quality of the cable used and the pixel controller
