Operation

GENERAL USE

In use, the X-DVIPRO and X-DVIPRO-MS2 modules should be transparent - the system

and its peripherals should operate exactly as normal, the only difference being that they

are now up to 50 meters apart.

Video display (EDID) information

Extended Display Identification Data (or EDID) is an industry standard scheme which

allows video displays to declare their capabilities to the computer's video adapter

circuitry, allowing the latter to optimize their outputs accordingly. Since the widespread

adoption of the scheme, video adapters have become increasingly dependent on receiving

relevant EDID information during start-up, before they will output anything more than a

rudimentary video signal.

Each time that the remote module is powered on, it attempts to read the EDID

information from the connected DVI video monitor. If the attempt is successful, the

information is transferred to the local module and stored within non-volatile memory.

This information is then made available to the computer's video adapter when required.

On MS2 variants, EDID is handled independently for the two video connections, allowing

completely different video display configurations on the two ports.

HDMI 1.3a operation

Using optional HDMI to DVI converter cables (Adder part number: VSCD11), the

AdderLink X-DVIPRO-MS can support HDMI video and audio up to the 165MHz clock

rate (1920 x 1080 at 60Hz, 24-bit color).

Eight channels of HDMI audio are supported with sample sizes of 16, 20 or 24-bits at

32KHz, 44.1kHz, 48kHz, 88.2kHz, 96kHz, 176.4kHz, or 192kHz (simultaneously with the

jack audio).

Note: The High-bandwidth Digital Content Protection (HDCP) and Consumer Electronics Control

(CEC) schemes are not supported.

Power and activity indicators

Each module provides two indicators to confirm power status and also feedback about

the various input signals:

Local module

Green:

• On when power is present.

Yellow:

• On when a valid DVI video input signal is being received

from the computer.

• Off when the CATx link cable is disconnected.

Note: On MS2 variants, the link ports are independent, so failure

of one link does not affect the video or USB status of the other

link.
