DVI DA2 and DVI DA4 1 Chapter One Introduction About this Manual About the DVI DA2 and DVI DA4 DVI DA2 and DVI DA4 Features
Introduction About This Manual This manual describes the installation, operation, and specifications of the Extron DVI DA2 and DVI DA4 Distribution Amplifiers. Unless stated otherwise, all references to the "distribution amplifier" or "the unit" in this manual refer to the features or operation of both models. About the DVI DA2 and DVI DA4 The Digital Visual Interface (DVI) Distribution Amplifiers (DAs) have one input and either two (DVI DA2) or four (DVI DA4) outputs.
DVI DA2 and DVI DA4 Features External power supply — The DVI DA2 and DVI DA4 are powered by an external 12 VDC power supply (provided with the units). DVI-D input — Both distribution amplifiers accept one single link DVI-D input, with a resolution range up to 1920 x 1200 or 1080p @ 60 Hz. Input Equalization — Input Equalization (EQ) conditions the input signals to ensure the integrity of the signals delivered to the output devices.

DVI DA2 and DVI DA4 2 Chapter Two Installation and Operation Installation Overview Mounting the Distribution Amplifier Front Panel Features Rear Panel Features Cable Connections Operation Troubleshooting
Installation and Operation Installation Overview Both distribution amplifiers can be mounted on tabletops, under furniture, and in racks by following these steps: 1. Turn off all electrical equipment. Make sure that the input sources, the DA and the output display(s) are all turned off and all power sources and signal cables are disconnected. 2. Mount the unit as described in "Mounting the Distribution Amplifier", below. 3. Connect the Cables (see "Cable Connections" on page 2-8). 4.
5. Reliable earthing (grounding) — Maintain reliable grounding of rack-mounted equipment. Pay particular attention to supply connections other than direct connections to the branch circuit (such as the use of power strips). Rack mounting procedure These distribution amplifiers can be mounted on any of the following rack shelves: • RSF 123 (part # 60-190-20) 1U 3.5" VersaTools® rack shelf kit • RSB 123 (part # 60-604-21) 1U 3.
Installation and Operation, cont’d 4. Attach the shelf to the rack with the four provided 10-32 x 3.4" screws. Under-desk mounting The DVI DA2 and DVI DA4 can be mounted under furniture using the optional Extron MBU 123 under-desk mounting kit (part # 70-212-01). Under furniture mounting To mount the unit under a desk or table: 2-4 1. If necessary, remove rubber feet from the bottom of the unit. 2. Secure the under-desk mounting brackets to the unit with the four provided 4-40 x 3/16" screws. 3.

Installation and Operation, cont’d Front Panel Features The front panels of the DVI DA2 and DVI DA4 are identical and shown in the illustration below. DVI DA SERIES DVI DISTRIBUTION AMPLIFIER 1 Front panel features a 2-6 LED indicator — On both the DVI DA2 and DVI DA4, the LED indicator illuminates green when the unit is receiving power.
Rear Panel Features DVI DA2 SUPPORTS DVI-D ONLY POWER 12V 0.4A MAX INPUT 2 1 LOCAL MONITOR OUTPUT 3 4 DVI DA4 POWER 12V 0.4A MAX DVI-D INPUT DVI-D OUTPUTS 1 2 3 4 LOCAL MONITOR 3 Rear panel features a b Power input — Connect the provided power supply to the 3.5 mm, 2-pole captive screw power receptacle. Input connector — Connect the input signal to the female DVI connector. The DVI input signal is equalized to ensure integrity.
Installation and Operation, cont’d Cable Connections DVI Connections 1. Use a DVI cable to connect the source device to the female DVI-I input. N Although DVI-I connectors are used, these distribution amplifiers are only compatible with single-link DVI-D video signals. For sources providing HDMI signals, use a HDMI to DVI adapter or cable, such as the Extron HDMIF-DVIDM female HDMI to male DVI-D adapter (#26-616-01) or the Extron HDMI M-DVI-D M series of HDMI male to DVI male cables (#26-614-xx).
DVI connector pin assignments The illustration below shows the pin assignments for the DVI-I male and female connectors. N Although DVI-I dual link connectors are used, the DVI DA2 and DVI DA4 are only compatible with single-link DVI-D video signals.

Operation 1. Connect the power supply (see page 2-10). 2. Connect and power on the local monitor (see page 2-8). 3. Connect and power on any other output displays (see page 2-8). 4. Connect and power on the source device (see page 2-8). N Output 1 (Local Monitor) is used as a DDC reference and must be connected to the distribution amplifier before the source device is powered on.
Installation and Operation, cont’d Troubleshooting No output signal — Check that the front panel LED is on (lit green). If it is not, check the power supply connections to the unit (see page 2-10). No output signal or poor quality signal — Check the integrity of the cabling to output 1 and ensure that output 1 (Local Monitor) is connected to the distribution amplifier before powering on the source device.
