Features & Configuration: HDBaseT & CATx Extension
Overview
The FLEX-CAT12OUT output card and FLEX-CATRX receiver extend 4K60 HDMI signals up to 100m over a single CAT6a cable, with Power over CATx (PoC) eliminating the need for local power at the receiver. This enables centralized matrix switching with distributed display connections across large venues.
SKUs
| SKU | Description | Role |
|---|
| FLEX-CAT12OUT | CATx Output Card for FLEX Modular Matrix | 12-port CATx output card — installed in FLEX chassis |
| FLEX-CATRX | FLEX Series 4K60 HDBaseT CAT Receiver | PoC-powered receiver at display end |
Signal Specifications
- Video: 4K60 4:4:4, HDR, HDCP 2.2
- Audio: HDMI embedded audio pass-through
- Cable: CAT6a required for 4K60 at full distance; CAT5e supported for 1080p up to ~70m
- Maximum distance: 100m (328ft) per segment
- Power over CATx (PoC): FLEX-CAT12OUT provides PoC to power the FLEX-CATRX receiver — no local power supply at display location required
Cabling Requirements
| Resolution | Cable | Max Distance |
|---|
| 4K60 4:4:4 | CAT6a (solid core) | 100m |
| 4K60 4:2:0 | CAT6 or CAT6a | 100m |
| 1080p60 | CAT5e / CAT6 | ~70m |
Important: Use solid-core CAT6a for best performance. Stranded patch cable is not recommended for long runs. Terminate with T568B pinout. Do not run CATx alongside high-voltage electrical cables.
Installation
- Install FLEX-CAT12OUT card in an output slot of the FLEX chassis.
- Enable PoC on each port via the web GUI (Output Card Settings → PoC Enable).
- Run CAT6a from each FLEX-CAT12OUT port to the corresponding display location. Label each run.
- Connect the CAT6a cable to the FLEX-CATRX RJ45 input port at the display end.
- Connect the FLEX-CATRX HDMI output to the display’s HDMI input.
- The receiver powers up via PoC — no power adapter required.
FLEX-CATRX LEDs
- Power LED (green): Receiver is receiving PoC power.
- Link LED (green): HDBaseT link established.
- Signal LED (green): Active video signal present.
Mixing HDMI and CATx Outputs
FLEX-HDMI12OUT and FLEX-CAT12OUT cards can be installed in the same chassis simultaneously. Assign outputs by card type — HDMI outputs for nearby displays, CATx for remote runs. Any input can be routed to any output regardless of card type.
