Colorlight K5H LED Receiving Card
The Colorlight K5H is a compact receiving card for LED display cabinets, including installations with limited internal space. The K5H V1.0.1 overview specifies a maximum loading area of 512 × 384 pixels and a 70.0 × 45.0 × 7.8 mm board. High-density connectors provide the module interface.
Image adjustment and maintenance
The K5H supports 8-bit video input, color-temperature adjustment, improved grayscale at low brightness and integrated per-pixel brightness and chromaticity calibration. Screen rotation, calibration sequence, data-group offset and eight-channel smart-module support are listed in its feature overview.
Maintenance features include fast firmware upgrades, rapid calibration-coefficient delivery and cabinet temperature, humidity, power-supply and voltage monitoring. Loop backup, dual-card backup, dual-power backup, and firmware backup and readback are supported. Match the backup wiring and monitoring hardware to the installation.

Frequently Asked Questions
What is the maximum K5H loading capacity?
The K5H overview in specification V1.0.1 lists a maximum of 512 × 384 pixels. Confirm the required driver IC, scan configuration and frame rate before using this maximum in a screen design.
Does the K5H support 240 Hz?
The K5H feature overview lists 240 Hz high-frame-rate support. It does not specify the pixel loading at that rate, so do not assume the maximum loading area and 240 Hz apply together.
How many data groups does the K5H support?
The overview lists up to 32 parallel data groups or 32 serial groups, expandable to 128 serial groups. The required connection and configuration depend on the module design.
What are the K5H dimensions and power requirements?
The card measures 70.0 × 45.0 × 7.8 mm. The equipment specifications list DC 5–12 V, 0.64 A input and 3.2 W rated power.
Which backup functions does the K5H support?
Its feature overview lists loop backup, dual-card backup, dual-power backup, and firmware backup and readback. Configure the required hardware and wiring for the selected backup method.
