INTERNAL BLOCK DIAGRAMS

DVI-7380-TX Internal Block Diagram

The DVI-7380 utilizes advanced fiber optic technology to extend DisplayPort and other AV signals over a single optical fiber. The TX accepts a DisplayPort input signal, which is sent to a receiver chip and then to a 4-channel optical transmitter utilizing wavelengths of 1270nm / 1290nm / 1310nm / 1330nm. At the same time the IR, RS-232 and Ethernet signals are combined in a SERDES and sent to a 2-channel optical transceiver using a wavelength of 1550nm. All optical output channels are combined into a single optical output signal with their respective wavelengths using a CWDM module (Coarse Wave Division Multiplexing). These optical output signals are connected to the RX unit via a single optical cable, which can span distances of up to 5.0 miles (> 8,000 meters). In addition to the optical output signals, the TX also accepts an optical input signal from the RX for IR, RS-232, Ethernet and AUX Channel communications using a wavelength of 1490nm.
DVI-7380-RX Internal Block Diagram

The RX accepts optical signals from the TX using multiple wavelengths over a signal optical fiber. These signals are connected to a CWDM module (Coarse Wave Division Multiplexing), which provides discrete optical outputs to a 4-channel optical receiver utilizing wavelengths of 1270nm / 1290nm / 1310nm / 1330nm. Using a DisplayPort transmitter chip, these signals, together with the AUX Channel signals, are sent to the DisplayPort Output port. At the same time, the combined IR, RS-232 and Ethernet signals are sent to a 2-channel optical transceiver using a wavelength of 1550nm. These signals are demultiplexed in a SERDES and sent to their respective output ports. In addition to the optical input signals, the unit also provides an optical output signal for the TX for IR, RS-232, Ethernet and AUX Channel communications using a wavelength of 1490nm.

6.1 Installation Instructions

1. Mount the TX and RX units as needed using the provided Mounting Brackets. See section 6.3 for more information.
2. Connect the TX to the DisplayPort output port of the signal source (e.g. PC) using a high quality DisplayPort cable.
3. Connect the RX to the DisplayPort input port of a destination device (e.g. digital display) using a high quality DisplayPort 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 RX unit. (6-1)
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 RX 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. 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 6-1: 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.
6.2 Optional Connections
In addition to the video signal, the DVI-7380 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 RX 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 6-2: 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 RX units to allow serial communication to pass-through via the optical link. Please refer to Warning 6-3 regarding wiring recommendations.

Note 6-3 – 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.
6.3 Mounting Hardware
Each TX and RX 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

Once all connections have been made and power has been applied to all components, this extension system should function immediately. This product has no adjustments and does not require configuration.

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 RX unit is connected to the Display using short, high quality DisplayPort cables.
• The fiber optic cable must be connected on both the TX Unit and the RX 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 RX units.

Once all connections have been verified, power ON the display first, and then the DisplayPort 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 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. (8-1)
Note 8-1: 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 Display Port 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.
