INTRODUCTION

The DVI-7365 is a high-performance, cost-effective, 4K Multiport Optical Extender designed to meet and exceed even the most demanding system requirements. It supports a wide array of signal types with or without HDCP content protection, provides long-distance extension over a single fiber cable, and supports ultra-high resolutions up to 4K (UHD) at 60Hz (4:4:4). This multiport optical extender supports uncompressed HDMI 4K /60p, embedded audio, bi-directional IR, RS 232 and two 10/100 BaseT Ethernet ports, using only a single fiber optic cable. It can extend these signals over cable distances of up to 1.86 mi. (3,000 meters). For added versatility, these units provide Advanced EDID Management with four operating modes: Pass-through, Learn 1, Learn 2, and Factory Default. Each extender set consists of an optical transmitter unit (TX) and an optical receiver unit (RX). The TX converts the AV signals into light pulses for transmission over a single strand of Multi-Mode or Single-Mode fiber optic cable. The RX converts the light pulses back to AV signals for the display, as well as other downstream devices. By using advanced fiber optic technology, without any compression, this product provides superior picture quality over greater distances than other extension methods, such as copper cables or CAT-X extenders. Together, these features make the DVI-7365 the ideal, cost-effective solution for system designers and integrators who need to support high resolution HDMI signals over extreme distances with flawless image quality.

Installation Instructions

1. Mount the TX and Receiver Units as needed using the provided Mounting Brackets. See section 4.3 for more information.

2. Connect the TX to the HDMI output port of the signal source (e.g. PC) using a high quality HDMI cable.

3. Connect the Receiver Unit to the HDMI input port of a destination device (e.g. digital display) using a high quality HDMI cable.

4. Connect an LC fiber optic cable (single strand of either Multi-Mode Fiber or Single-Mode Fiber) between the Optical Output port on the TX Unit and the Optical Input port on the Receiver Unit. (4-1)

5. Connect other peripheral devices to the units as needed (see section 4.2).

6. Connect the supplied External AC Power Adapters to the power input jack on the TX and Receiver Units. Once the plug is inserted into the jack, rotate the locking nut on the plug clockwise until it is tight, to secure the cable. There is no power switch on these units. The units will turn ON as soon as the AC Power Adapter is connected to a live AC power receptacle. In the event of a power failure, the EDID files stored in the TX will not be affected as they are stored in non-volatile memory.
   Use only the supplied power adapters to avoid the possibility of equipment damage.

7. Apply power to the display device, then apply power to the source device. A picture should appear on the display within a few seconds. Next apply power to any connected peripheral devices.

Note: This product supports the use of both Single-Mode Fiber (SMF), and Multi-Mode Fiber (MMF). However, extra care is required when using SMF due to its smaller optical aperture (8.9 microns) versus 50-60 microns for MMF. This smaller aperture means that SMF optical cables have an increased risk of contamination due to dirt, dust, oils, etc. that can be caused by poor handling.

Optional Connections
In addition to the video signal, the DVI-7365 supports extension of other signal types over the fiber link. These pass-through connections can be used to provide communications with other devices in the system. These connections include 10/100Base-T Ethernet, bidirectional IR, and RS-232.

• LAN Ethernet RJ45 port
  Connect to the LAN port of a peripheral device to provide a 10/100Base-T connection via the fiber link.

• IR Connections
  Each extender set supports bidirectional IR communications. The TX and Receiver Units each have two IR ports on the rear panel, labeled “IR IN” and “IR OUT”. To set up the IR data pathway, connect an IR receiver device (1x is included) to an “IR IN” port on one unit. Next, connect an IR transmitter to the “IR OUT” port of the other unit. Any IR communications directed to the IR receiver module on one end of the extender set will be sent out of the IR transmitter module at the other end. For bidirectional communication, an additional IR TX and RX (purchased separately) may be connected. This allows IR data to be sent upstream, downstream, or both.
  Note: For best results, it is critical to carefully position the IR Transmitter and IR Receiver modules. The IR RX module should be placed where the user would typically aim the remote control. The IR TX module should be placed in close proximity to the IR window of the device being controlled. The IR TX module includes double-sided tape that can be used to adhere it in place.

• RS-232 Connections
  Connect to an RS-232 device on both the TX and Receiver Units to allow serial communication to pass-through via the optical link. Please refer to Warning 4-3 regarding wiring recommendations.

• Note – WARNING: DVIGear recommends that only qualified technical personnel be permitted to wire the Phoenix connectors as improper wiring can cause equipment damage. For best results, it is important to use stranded wires and avoid tinning the wire ends as this can allow them to be removed too easily from the Phoenix receptacles.

Mounting Hardware
Each TX and Receiver Unit comes with a pair of Mounting Brackets to facilitate installation on furniture or other surfaces. These Mounting Brackets are reversible, so the unit may be installed above or below the mounting surface. The units are shipped with the brackets installed in the “above mount” configuration. To change the orientation of the mounting brackets, first remove the two screws on the sides of each bracket and set them aside. Next, flip the mounting brackets into the desired position and screw them into the two mounting holes located on each side of the extender units.

OPERATING THE UNIT

In most cases, the default configuration is sufficient for proper operation; however, this extender set includes 4x EDID modes to optimize system performance. EDID (Extended Display Identification Data) is a small data file stored in virtually every TV, monitor and display device made over the last twenty years. This file contains information about the display’s capabilities, such as its supported resolutions, refresh rates, color space, type of display, manufacturer, serial number, etc. After connecting a display to a source device, the source reads and saves the EDID in order to determine the most suitable display parameters (e.g. resolution and refresh rate). In this way, EDID plays an essential role in the modern “Plug & Play” user experience.
The DVI-7365 has four (4) EDID operation modes:

Note: Pass-through EDID mode is the only mode that supports live DDC communications. The extender can be set to different EDID modes by using the DIP switches on the rear of the TX Unit. The EDID LED on the front panel of the TX Unit will change based on the current mode being used.

Learning an EDID

1. Set the EDID switch on the Transmitter to the desired EDID learning mode (EDID Learn 1 or EDID Learn 2).
2. Connect the HDMI input on the Transmitter to the HDMI input port on the display using a short, high quality cable.
3. First, supply power to the display. Next, supply power to the Transmitter. The EDID LED on the front panel of the Transmitter should light up blue. Now, press and hold the EDID button on the front panel of the Transmitter for about 2 seconds and then release.
4. If the EDID has been successfully learned, the EDID LED will blink once. The saved EDID file will be stored in non-volatile memory. If the EDID learning process fails, then the EDID LED will flash 5 times. In this case, repeat steps 1-4 above. Contact technical support if further assistance is required.
5. Finally, disconnect the Transmitter from the display. Continue with system setup as described in section 4.1.

TROUBLESHOOTING

If the system fails to display a signal, power OFF all devices and verify that the following connections are properly installed:

• Ensure the TX Unit is connected to the source and the Receiver Unit is connected to the Display using short, high quality HDMI cables.
• The fiber optic cable must be connected on both the TX Unit and Receiver Unit. Check to ensure that the optical cable is fully inserted into the ports. Note that slight pressure on the fiber optic cable and/or connector should NOT have any influence on the image quality of the signal.
• The supplied External AC Power Adapters should be connected to both the TX and Receiver Units.

Once all connections have been verified, power ON the display first, and then the HDMI signal source. If there is no picture or if there are intermittent picture issues, please determine whether the Fiber Link LEDs are lit. If the Fiber Link LEDs light up, then there may be an EDID issue. Please check to be sure the appropriate EDID mode is being used. See section 5.0 for information on setting the EDID mode of the extender. If the Fiber Link LEDs are not lit, then it may be necessary to check the quality and/or condition of the fiber optic cable being used. Fiber optic ports and cables are very sensitive to dust, dirt and oil from handling. Even minute amounts of obstructive material can interfere with or disrupt the optical transmission of the video signals. If erratic performance or disruption is noted, it may be necessary to have qualified technical personnel clean the optical ports and/or optical cable using appropriate procedures and cleaning materials.(6-1)

Note: This product supports the use of both Single-Mode Fiber (SMF), and MultiMode Fiber (MMF). However, extra care is required when using SMF due to its smaller optical aperture (8.9 microns) versus 50-60 microns for MMF. This smaller aperture means that SMF optical cables have an increased risk of contamination due to dirt, dust, oils, etc. that can be caused by poor handling.

If the system still fails to display an image, ensure that the HDMI signal source is compatible with the display by making a direct connection between the two, bypassing the Fiber Optic Extender. If there is still no image, then there is a compatibility issue between the source and the display that must be resolved. If the problem persists after trying the above suggestions, please contact your dealer for additional assistance.
