MAGENTA MULTIVIEW™ SERIES

Appendix H. DDC Modes

The MultiView XRTx features the ability to send DDC/EDID display identifiers to the

video source in order to determine display capabilities. The DDC is a data

communication channel used in plug and play devices to accurately report a displays

capabilities and identify the manufacturer. If this data is not available, the video source

may revert to a low resolution or not display at all.

The MultiView XRTx features the ability to report a Universal Display (MRI Magic

Display) that supports most popular VESA standards in standard or widescreen formats

as well as the ability to clone an actual displays DDC information that is attached to

either the local output of the transmitter or copied from an actual display.

The XRTx transmitter unit has 3 DDC modes of Operation:

Mode 1: DDC Mock Mode

This is the default mode which uses generic DDC information stored within the

transmitter and reports this to the video source when requested.

To activate this mode, set the DDC Mode switch to the A position.

Mode 2: DDC from Local Monitor Port

The DDC information is transferred from a display connected to the local port of the

transmitter back to the video source. The local monitor must remain connected at all

times.

To activate this mode, set the DDC Mode switch to the B position.

Mode 3: Copy DDC information from a display into the XRTx memory.

In this mode, DDC information is first copied from a display into the XRTx transmitter

and stored in non-volatile RAM. Then the transmitter is connected to a video source

and reports the copied DDC information to the video source when requested.

To activate this mode, set the DDC Copy switch to the B position and do

the following:

• Connect Display to the Local monitor port on the transmitter

• Set DDC Copy switch to B

• Press the Enter button

• DDC LED will flash 3 times indicating a successful copy.

• Disconnect display and reconnect video source.

To restore the default generic DDC information:

• Set DDC Copy switch to A, then press the Enter button

• The DDC LED will flash 2 times to confirm restoration.
