Colorlight i9 LED Receiving CardDDR2-200 Receiver — 32 RGB Groups, Independent RGB Gamma, Low Latency
Colorlight i9 LED receiving card with the J28 DDR2-200 interface: 32 RGB data groups, independent RGB gamma adjustment, low-latency processing and firmware upgrades without power restart — supplied by Excelled, a trusted LED screen manufacturer for global B2B buyers.

What Is the Colorlight i9 LED Receiving Card?
The i9 LED receiving card is the gamma-tuning generation of the Colorlight i-series. Built on the J28 DDR2-200 connector, it carries 32 RGB data groups plus SPI, UART/I2C and monitoring pins on one 200-pin edge — the same ecosystem footprint as the i6, with three flagship features: independent RGB gamma adjustment, low latency, and firmware upgrade without power restart.
Independent RGB gamma means the red, green and blue channels are tuned separately instead of one shared curve — the correction step installers use to remove color casts at low brightness on fine-pitch screens.
• Interface: J28 DDR2-200 200-pin connector.
• Output: 32 RGB data groups; SPI×8; UART/I2C.
• Features: independent RGB gamma adjustment, low latency.
• Firmware: upgrade without power restart.
• Monitoring pins: temperature, humidity, fan control; RCV_BK backup pins.

Colorlight i9 LED Receiving Card Specifications
The official i9 specification (V1.4.1) documents the J28 pin mapping in full; feature claims below are taken from the official specification and the product’s official feature diagrams. Download the datasheet PDF for the complete pin table.
| Parameter | Specification |
|---|---|
| Product Type | LED receiving card, J28 DDR2-200 interface (200-pin edge connector) |
| Data Output | 32 RGB data groups (LED_R1–R32 / G / B) per the J28 pin mapping |
| Expansion Interfaces | 8× SPI channels (SCK/SDI/CS/SDO), UART_TX/RX with I2C_SCL/SDA |
| Monitoring Pins | LED_TEMP (temperature), LED_HUM (humidity), LED_FAN (fan control), LED_BTN_IND, 5× Power_M monitoring |
| Backup Pins | RCV_BK1 / RCV_BK2 (receiver backup signaling) |
| Indicator Outputs | LED_RED / LED_GREEN / LED_BLUE status pins |
| Key Features | Independent RGB gamma adjustment; low latency; firmware upgrade without power restart |
| Ecosystem | Same J28/DDR2 footprint family as the i6; pairs with Colorlight senders and LEDVISION configuration software |
Evidence note: pin-level facts cross-checked against the official i9 specification V1.4.1 (J28 pin mapping). Feature facts (RGB gamma, low latency, restart-free firmware) are taken from the official specification’s feature diagrams. Where the datasheet does not publish a parameter (e.g. per-card pixel capacity), the value is not stated on this page rather than borrowed from sibling models.
Why the i9 Adds Independent RGB Gamma
Three Curves Instead of One
A shared gamma curve corrects brightness but leaves color casts. The i9 tunes red, green and blue independently — the tool that fixes magenta-shifted shadows on fine-pitch cabinets without touching module hardware.
Low Latency for Live Feeds
Low-latency processing keeps the card suitable for control rooms and live events where every frame of lag is visible against the source.
Firmware Without Downtime
Upgrading most receivers means power-cycling the whole chain. The i9 applies firmware upgrades without power restart — the difference between a 2-minute maintenance window and a full screen outage on a live site.

i9 Card Quantity Estimation
The i9 shares the i-series data-group architecture; sizing follows the same three-step rule as any receiving card plan.

When Should You NOT Choose the i9?
• You need 60P outputs for casting aluminum mini cabinets — the Colorlight i5A-905 is built for that form factor.
• You need 64 data groups — the Colorlight i9+ doubles the output groups.
• You prioritize monitoring depth (bit-error, 5 voltage channels) — the Colorlight i6 documents that set explicitly.
• You need 1/64 scan — the i-series supports static to 1/32 scan.
The i9 earns its place when gamma tuning and low latency matter — outside that, sibling models cover the job.

How to Wire the i9 Receiving Card
The J28 edge connector carries data, power and monitoring on one interface — the same socket pattern as the i6.
- Mount: seat the 200-pin J28 edge into the cabinet HUB board.
- Network: RJ45 daisy chain between cards.
- Monitoring (optional): temperature, humidity and fan pins to the multifunction board.
- Backup (optional): RCV_BK1/BK2 wiring for receiver backup signaling.

i9 Setup with LEDVISION — Step by Step
The i9 is configured inside Colorlight’s LEDVISION software as part of the full control system.
- Step 1 — Install LEDVISION and connect the sender.
- Step 2 — Detect: LEDVISION finds the card chain automatically.
- Step 3 — Screen setting: cabinet files, module layout, scan mode.
- Step 4 — Gamma: enable independent RGB gamma adjustment and set the three curves.
- Step 5 — Verify at low brightness: check 10%/30% brightness for color casts.
- Step 6 — Firmware: apply upgrades without power restart.
- Step 7 — Backup: save the configuration file for field replacement.


i9 Common Issues & Diagnostic Procedures

Q2 What is independent RGB gamma adjustment?
Red, green and blue channels are tuned on separate gamma curves instead of one shared curve – the correction for color casts at low brightness on fine-pitch screens.
Q3 Can the i9 firmware be upgraded without restarting?
Yes. Firmware upgrades apply without power restart, avoiding screen downtime during maintenance.
Q4 Does the i9 support monitoring?
