Colorlight HC5 receiving card for 5Gb/s LED systems
The Colorlight HC5 is a high-density-connector receiving card for fine-pitch fixed and rental screens. Its wired network transmission rate is 5Gb/s. The specification distinguishes up to 3.25 million pixels carried through one network cable from the maximum 256 × 1024-pixel control area of a single card.
Video quality and cabinet operation
HC5 supports 8-bit, 10-bit and 12-bit video sources, HDR, independent gamma adjustment and multi-layer calibration. Low-grayscale calibration, Infi-bit processing and grayscale refinement provide tools for adjusting fine-pitch screen uniformity. Up to 14-bit calibration precision applies to brightness and chromaticity.
Cabinet highlighting, OSD, seam correction, rotation and a pre-stored picture assist installation and service. Loop redundancy, dual-card hot backup and backup of firmware, configuration and calibration data support appropriately designed systems. Cabinet monitoring functions depend on the cabinet connections and sensors.
Technical parameters
| Parameter | Specification |
|---|---|
| Network signal rate | 5 Gb/s over a wired network connection |
| Cable loading | Up to 3.25 million pixels per network cable; not the single-card control area |
| Single-card loading | Maximum 256 × 1024 pixels; feature-dependent |

| Data groups | 32 parallel RGB; 64 serial RGB, expandable to 128 |
| Driver / scan support | PWM chips; up to 128 scan lines |
| Module capacity | Up to 16,384 pixels per data group |
| Calibration | Up to 14-bit brightness and chromaticity accuracy |
| Interface | High-density JH1/JH2 connectors |
| Dimensions (L × W × H) | 80.0 × 45.0 × 7.4 mm |
| Weight | 23 g without heatsink; size and weight vary with manufacturing process |
| Power input / rated power | DC 3.8–5.5 V, 1.3 A / 6.1 W |
| Operating conditions | −25 to 75°C; 0–80% RH, non-condensing |
Confirm the sender, cabling and cabinet HUB design for the intended 5Gb/s operation. Higher frame rates, including 120/144/240 Hz, affect loading capacity. A network transport limit does not replace the individual receiving-card limit.
Frequently asked questions
Does “5G” on Colorlight HC5 mean cellular 5G?
Here it refers to the documented 5Gb/s wired network signal rate for the LED control system, not a cellular mobile-data function.
Can one HC5 receiving card control 3.25 million pixels?
No. The PDF describes up to 3.25 million pixels through one network cable, while a single HC5 card has a maximum 256 × 1024-pixel control area. Enabled features can change loading.
Does HC5 support 12-bit video and HDR?
Yes. The specification lists a maximum 12-bit input/output path and HDR support. Sender, source and cabinet configuration must be checked for the intended workflow.
What power supply does HC5 require?
The specification lists DC 3.8–5.5 V, 1.3 A and rated power consumption of 6.1 W. Match the actual board revision and cabinet power connections before installation.
Does HC5 include cabinet monitoring and hot backup?
The card supports these functions, but monitoring requires the corresponding cabinet connections or sensors. Hot backup uses two receiving cards connected through a suitable HUB board to control one cabinet.
