Not a processor but the panel-side receiving card of the Tessera system: compatible with every Brompton processor and able to serve even the finest pixel pitch panels.
Brompton · receiver card for the Tessera system
Brompton Tessera R2+ LED wall processor
One point to clarify: the R2+ is not an LED processor but the receiver card of the Tessera ecosystem, which sits in a DDR2 SO-DIMM socket on the back of the LED panel or module, takes the Gigabit Ethernet signal from the processor (SX40, S8, T1, M2, SQ200) and drives the panel's driver ICs. Compared with its R2 predecessor it offers more processing capacity: 262,144 RGB pixel capacity, 16-bit per channel processing and up to 144 output data channels.
The card's key functions include module-based calibration data storage (modules can be swapped without recalibration), advanced calibration options (On-Screen Colour Adjustment for compensating mechanical seams, for instance), and excellent grayscale performance combined with Brompton's Dark Magic and PureTone functions.
At only 68×32 mm it fits easily into modern, ever smaller hub board designs. It has two Gigabit Ethernet data links and supports every significant driver IC.
Where the Tessera R2+ sits in an LED wall system
The R2+ is the panel-side end point of the signal path: it goes into the DDR2 SO-DIMM socket on the module's hub board, takes the gigabit Tessera signal from the processor (SX40, S8, M2, T1, SQ200) and drives the driver ICs over as many as 144 data channels, up to 262,144 pixels at 16 bits per channel. This card is what makes a panel "Brompton compatible": when a manufacturer prints that on a module, it means the hub board takes an R2+ mechanically and electrically — and only in that way are HDR, Extended Bit Depth and Dynamic Calibration live on the processor.
WHEN IT IS THE RIGHT CHOICE
For LED panels used with any Brompton Tessera processor (SX40, S8, T1, M2, SQ200), especially on sub-2 mm fine-pitch products where module-based calibration storage matters.
WHAT TO WATCH OUT FOR
It works exclusively with the Brompton Tessera protocol and is not compatible with other manufacturers' sending cards or processors (NovaStar, Colorlight); the HDR and Extended Bit Depth functions on the processor are only available with an R2/R2+ card.
The Tessera R2+ in practice
The card's most important operational consequence is module-based calibration data storage: the calibration coefficients live with the module, so a module can be swapped without having to re-measure the wall — on a rental fleet this saves several days of work a year, because even mixed cabinets colour-match. At commissioning the firmware version has to be aligned with the processor's: the Tessera Management Software flags any discrepancy, and the update runs through the wall cabinet by cabinet — on a large wall this takes hours, so it should not be done on show day. The two gigabit data links are what make closed loop redundancy possible, but only if the loop really is wired back.
Alternatives to the Tessera R2+
Within the Tessera system there is no alternative to it: the card works exclusively with the Brompton protocol and cannot be connected to a NovaStar or Colorlight sending card. If the panel park is built on a different ecosystem, the A10s Pro or the CA50E on the NovaStar side and the i9 on the Colorlight side are the equivalent level — cheaper, but without Brompton's HDR and calibration functions. In practice the choice is settled together with the processor.
