The DiGidot PxLNet Transmitter is a data range extender that converts SPI signals to the DiGidot PxLNet protocol.

PxLNet is used to transmit SPI signals to receiver modules up to 250 meters away.

You can also use the PxLNet Transmitter to convert DMX TTL (which can be selected as output protocol in the DiGidot C4) to regular and balanced DMX512. This allows you the get four DMX universes out of the DiGidot C4 instead of two.
