T120 receiving card: load modes and hardware revision
The Mooncell T120 is a compact LED receiving-card core board with 24 groups of RGB parallel data. The linked specification describes AutoLED configuration, pixel correction, rotation, scaling and network-port hot backup.
Match the document to the board: the linked T120 V3.0 specification identifies T120S V1.1 hardware in its revision record. Its voltage, scan and correction-load limits differ from the original product description. The table labels these differences rather than treating all revisions as having identical ratings.
Technical specifications
| Parameter | Specification |

Frequently asked questions
Does calibration reduce the T120 pixel load?
The original listing says correction does not reduce load, but the linked V3.0 PDF gives separate limits: 256 × 384 maximum, 256 × 308 with brightness correction and 256 × 256 with chromaticity correction. Confirm the hardware revision and use its matching correction-mode limits.
What supply voltage is specified for T120?
The original page states +3.5–6 V. The linked V3.0 PDF, whose revision record names T120S V1.1 hardware, states DC 3.5–5.5 V. Do not assume the higher voltage is approved for every T120 board revision.
Does every T120 include dual-power backup?
No such universal inclusion is established. The PDF labels dual-power backup as a customized feature. It separately describes network-port hot backup using main and standby cable paths.
Which software is listed for setup and diagnostics?
The linked PDF names AutoLED for configuration readback, cable bit-error monitoring, communication status, layout, rotation and scaling. Match the installed hardware and firmware to the appropriate software.
What does a green status light that is off indicate?
For the hardware documented in the linked PDF, the green U2 indicator being off means no Gigabit network signal. Slow flashing indicates a normal connection without DVI input; fast flashing indicates DVI input. Check the board revision before applying those indicator definitions.
