Booster Pair

P T/R

SPI extender pair. The PXT/R transmitter and receiver convert standard SPI signals to differential X-Stream and back — extending pixel data up to 100 m with redundant data lines, a wide 12–48 V DC input and a compact footprint that drops into any installation.

  • Range Up to 100 m extension
  • Signal SPI ↔ X-Stream differential
  • Redundancy D1 + B1 backup data
  • Power 12–48 V DC, 6 A

Common questions, answered.

It is an SPI extender pair — 1× PXT transmitter and 1× PXR receiver — that regenerates pixel data over long runs.
Up to 100 m between the PXT and the PXR.
The PXT takes SPI / X-Stream in and sends X-Stream differential out; the PXR takes X-Stream differential in and outputs SPI / X-Stream.
Yes — a D1 standard line plus a B1 backup line for data redundancy.
On a wide 12–48 V DC input, up to 6 A per unit.
Each unit is surface-mounted (4× Ø4.5 mm holes), rated IP20 for indoor use, and measures 93 × 64.6 × 30 mm.
