Welcome! Product Description
Welcome!
Congratulations on your purchase of the two (2) fibers DisplayPort extender, FX-D250. This manual contains information that will assist you in installing and operating the product.
Product Description
New compact optical DisplayPort extender, FX-D250 enables to transmit 4K (4096x2160) at 60Hz signal up to 100m (328feet), avoiding any tricks like scaling or data compression for lessening a burden of data transmission. It provides total data throughput 21.6Gbps (5.4Gbps per lane).
The OM3 fiber connection by two (2) LC fibers connector between transmitter and receiver, gives clean, secure and easy installation with perfect electrical isolation, but without electrical hazard and interference. The FX-D250 can be operated by either USB power by plugging the USB cable or 3.3V from pin #20 of DisplayPort interface.

System Requirements for Setup
Hardware Requirements
- You have to have a DisplayPort source and display. It should support the maximum graphic resolution feature of displays to be connected.
- No special requirements of memory size, CPU speed and chipsets, if you’ve already properly installed your DisplayPort systems or graphic cards.

- Proper initial trial of the entire platform with its application using a short length copper cable is recommended prior to installation with the optical link.
Software Requirements
- No special restrictions, if you’ve already properly installed your DisplayPort systems.
Power Technical Advisory
- Enclosed Power Adaptors and USB cables supply power to both Transmitter and Receiver.
Installation
Connection Advisory
- It is highly recommend that DisplayPort source is directly connected into DisplayPort display output via FX-D250 without connection to incompatible distributor, switcher and selector.
The Shipping Group of FX-D250;
- One (1) Transmitter (Tx) and One (1) Receiver (Rx)
- One (1) 0.2m Male to Female DisplayPort copper cable
- Two (2) Micro USB to USB cables
- User’s Manual
- Default connection is direct connection to both source (Tx side) and display (RX side)
- If direct connection is impracticable, 0.2m DisplayPort copper cable is strongly recommended to use on TX (Display Source) side only

IMPORTANT: PLEASE KEEP THE INSTALLATION PROCEDURE BELOW. IMPROPER OR NO OPERATION MAY RESULT IF THE START-UP SEQUENCE IS NOT CORRECTLY FOLLOWED.
- Carefully unpack the contents in the shipping group.
- Power on the DisplayPort source and display. Both the transmitter and receiver will be turned on by 3.3V from pin #20 of DisplayPort interface. The USB power is recommend for the stable power supply for both the transmitter and receiver.
- The Power LED will be turned on when FX-D250 is connected to DisplayPort interface of signal source and display and the Status LED will blink three (3) times. Then the Status LED will blink again when the whole connection is made.
- Connect two (2) LC optical fibers between the transmitter and the receiver and each fiber channel shall be connected as (A) to (A) and (B) to (B) carefully. Ensure the duplex connectors are fully engaged and then, the top LED will begin to blink regularly. Note1: Please DO NOT look directly into the LC receptacles of the Transmitter, while it is powered on, although this product is regulated strictly enough to operate under the LASER Class I, classified by CDRH/FDA for eye safety. Note2: The maximum extension length by OM3 fiber is 100 meters. Note3: Be recommended NOT to use any intermediate cable or adapter between them to avoid undesirable performance degradation.

- Connect the transmitter to the DisplayPort source
- Connect the receiver to the DisplayPort source. Note: If the connectors are fully engaged, the bottom LED will turn on.
- If the system does not work properly, go to the page 1-6 trouble shooting.

Troubleshooting, Maintenance
Troubleshooting
- The display shows only black screen.
- Ensure that all plugs and jacks used by USB power supplies are firmly connected. Ensure that the LED is ON.
- Ensure that the DisplayPort is firmly plugged in to the DisplayPort source and display.
- Ensure that the transmitter and receiver modules plugged correctly to the source and display, respectively.
- Check if the DisplayPort source and display are powered on and properly booted.
- Reset the system by de-plugging and re-plugging the transmitter DisplayPort or receiver DisplayPort, or by de-plugging and re-plugging the USB power cables that are plugged of the transmitter and receiver module
- Re-boot up the system while connecting the module.
- Screen is distorted or displays noises.
- Check if the graphic resolution is properly set. Go to the display properties and tap the settings. Ensure that the resolution sets less than WQUXGA (3840x2400) at 60Hz refresh ratio.
- Reset the system
- Power down, disconnect and reconnect the optical system cable or USB power adaptors, and power up
Maintenance
No special maintenance is required for the optical system cables and power supplies. Ensure that the cables and power modules are stored or used in a benign environment free from liquid or dirt contamination.
There are no user serviceable parts.
