CAT Cable Requirement — Critical
Use high-quality CAT6 / CAT7 cable.
| Requirement | Specification |
| Cable type | CAT6 / CAT7 |
| Wiring | Straight-through 568B standard |
| Maximum distance | 230ft / 70m at 1080p@60Hz |
| Connection | Transmitter CAT OUT to Receiver CAT IN |
Poor CAT cable may cause:

- Flickering
- Black screen
- Receiver not powering on
- Wrong resolution
- Audio dropouts
- Signal instability
- Reduced working distance
Use direct cable runs whenever possible.
HDMI Cable Requirement — Critical
Use high-quality HDMI cables between:
- HDMI source and Transmitter HDMI IN
- Transmitter HDMI LOOP OUT and local display
- Receiver HDMI OUT and remote displays
Poor HDMI cables may cause:
- No picture
- Flickering
- Black screen
- No audio
- Wrong resolution
- HDCP handshake issues
- Local HDMI loop output issues
- Receiver output issues
For troubleshooting, test the HDMI source directly with a display before using the extender splitter.
Power Requirement — Critical
The HD14-EX132-K uses one DC 12V/1A power adapter.
| Unit | Power |
| Transmitter | DC 12V/1A |
| Receivers | Powered through CAT cable using Power over Cable |
| Power Detail | Value |
| Power adapter input | AC 100–240V 50/60Hz |
| Power adapter output | DC 12V/1A |
| Maximum power consumption | 7.3W |
If a Receiver does not power on, check the Transmitter power, CAT cable connection, CAT output port, and Receiver CAT IN connection.
Understanding the Transmitter
The Transmitter is installed near the HDMI source.
It has:
- HDMI IN
- HDMI LOOP OUT
- Four CAT OUT ports
- EDID DIP switch
- SERVICE USB-C firmware port
- DC 12V input
- Power switch
- Power LED
The Transmitter duplicates the HDMI input signal and sends it to one local display and four remote Receivers.
Understanding the Receivers
Each Receiver is installed near a remote display.
Each Receiver has:
- CAT IN
- HDMI OUT
- POWER LED
The Receiver receives the CAT signal from the Transmitter and outputs HDMI to the connected display.
Understanding HDMI Loop Output
The HDMI LOOP OUT port allows a nearby display to show the same HDMI source.
This is useful for:
- AV racks
- Source rooms
- Control desks
- Classrooms
- Bars
- Restaurants
- Retail signage
- Installation testing
The HDMI LOOP OUT display and all four remote Receiver displays show the same content.
Understanding EDID
EDID tells the HDMI source what video and audio format to output.
Use EDID when:
- There is no video
- One or more displays show no signal
- Audio does not work
- The source outputs the wrong resolution
- Displays have mixed audio capability
- The HDMI loop display needs to control the EDID
For most setups, start with 1080p, 2.0CH. If using surround sound, select a 5.1CH or 7.1CH EDID setting supported by the source and connected audio/display devices.
