CONNECTING AND OPERATING THE DVI•2500HD DDC Modes DVI•2500HD can operate in 2 DDC modes. It is important to determine the DDC mode before attempting to connect anything to the DVI•2500HD units. The DDC will carry EDID information which is critical in determining a connected device’s resolution capabilities and operational limits. This section will outline the 2 modes and list the features of each.
CONNECTING THE DVI•2500HD IN DDC MODE 1. Locate the DDC Mode switch on the front panel of the DVI•2500HD Sending unit. Ensure that the switch is set to Direct DDC. 2. Connect a DVI cable (one is supplied) between the DVI source device’s DVI output and the DVI•2500HD Sending unit’s DVI input. 3.
CONNECTING THE DVI•2500HD IN VIRTUAL DDC MODE 1. Locate the DDC Mode switch on the front panel of the DVI•2500HD Sending unit. Ensure that the switch is set to Virtual DDC. 2. Record the DVI-capable output device’s (i.e. DVI display) EDID into the DVI•2500HD Sending unit. The instructions below will use a computer display with a DVI input as an example for a DVI-capable output device: 1. Move the DVI•2500HD sending unit to the DVI display’s location or bring the DVI display to the Sender’s location. 2.
CONNECTING THE DVI•2500HD IN VIRTUAL DDC MODE 5. Connect a DVI cable between the DVI•2500HD Receiving unit’s DVI output and the DVI-capable output device’s (i.e. DVI display) DVI input. 6. Connect both of the included 12V DC power supplies between the Sending and Receiving units and open wall power sockets. 7. Initialize (power on) the DVI-capable output device (i.e. DVI display) first, then the DVI source device.
