M-HFK20U 4K HD+KVM Fiber Extender

Introduction

M-HFK20U transmits high-definition video signals over long distances through optical fiber, supports KVM or

RS232 function, and can operate remote devices using keyboard and mouse or RS232. 

This product transmits HD high-definition audio and video signals with resolution of 3840*2160@60Hz over

20KM without compression through 10 Gigabit optical fiber, it supports KVM signal or RS232(optional), independent

audio transmission, and supports local loop output, which reduces costs for users while ensuring signal stability.

This model has a built-in learning EDID function, which greatly improves the compatibility of the device.

This equipment has long transmission distance, low cost of use, easy installation, good compatibility, and is a

stable and efficient transmission method. It is widely used in audio and video transmission of high-definition

conference systems, high-definition film and television shooting, high-definition teaching systems, high-definition

digital advertising, etc.

Product Interface

TX: Transmitter

RX: Receiver

Installation Process

1. Connect the HD signal source to the HD input port of the TX

2. Connect the HD OUT of the RX to the display device                                   

3. Use an optical fiber cable to connect the optical fiber port of TX and RX

4. Connect the TX and RX to the power supply. When the indicator light P/S is always

  on, light F flashes quickly, it is working.

Troubleshooting

1. The red light (P) is not bright or the brightness is low, Check whether the power 

  adapter is normal

2. The green light (S) is not on, Check if the signal source has started or output; The

  green light stays on indicates regular work

3. The green light (F) is not on, check if the fiber optic module is plugged in properly

  and if the fiber optic cables are working properly; (F)Flashing light indicates

  regular work

4. If there is no image on the display, check if the display has selected the correct

  channel input. If the image is abnormal, refer to the EDID function application

EDID Button pressing method: If all the indicator lights of the transmitter 

and receiver are normal after being connected, but the monitor has no image, 

changes color, or is not full of the screen, connect the HD interface of the

monitor to the HD OUTPUT interface of the TX, power on, and press and

hold EDID button, the OUT indicator light flashes. After continuous flashing

for 5 seconds, the learning is completed, and reconnect the TX.
