Wiring the Power Connector for the connection procedure.

HDMI output connector — Connect an HDMI sink to this female HDMI connector.

• No input signal — When there is no input signal present, this connector does not

output TMDS data or clock activity. This ensures that any downstream device does

not erroneously detect a signal.

• Output 5 V mode — This mode is configurable via SIS commands (see the

5 V Output Hot Plug Mode commands on page 16). Select either of the following:

• Always enabled — The 5 V pin is always active, regardless of the input signal

status. This enables the unit to detect hot-plug assertion and read the EDID

from a connected sink.

• Auto — 5 V output is active only when a source is connected to the input. If

no source is connected the 5 V output is disabled. (This may be necessary for

some sinks to enter power save mode.)

Secure the HDMI output cable to the HDMI connector using the LockIt bracket (see

Securing the HDMI Connector Using the LockIt Cable Lacing Bracket on

page 7).

Config port — Use a USB A-to-mini B cable to connect this port to a USB port on the

Wiring the Power Connector

The DVC RGB-HD A requires a 12 VDC, 1 A power supply to power it.

CAUTION: The wires must be kept separate while the power supply is plugged in.

Remove power before wiring.

ATTENTION : Les deux cordons d’alimentation doivent être tenus à l’écart l’un

de l’autre quand l’alimentation est branchée. Couper l’alimentation avant de faire

l’installation électrique.

ATTENTION:

• Do not connect any external power supplies until you have read the Attention

notiﬁcations beginning on the next page.

• Ne branchez pas de sources d’alimentation externes avant d’avoir lu les mises en

garde sur la page suivante.

NOTE: The 12 VDC power supply is not included, but can be ordered at

www.extron.com.

SECTION A–A

Figure 4. Wiring the Power Connector

ATTENTION:

• Always use a power supply supplied and or speciﬁed by Extron. Use of an

unauthorized power supply voids all regulatory compliance certiﬁcation and may

cause damage to the supply and the end product.

• Utilisez toujours une source d’alimentation fournie ou recommandée par Extron.

L’utilisation d’une source d’alimentation non autorisée annule toute conformité

réglementaire et peut endommager la source d’alimentation ainsi que le produit

ﬁnal.

• If not provided with a power supply, this product is intended to be supplied by a

UL Listed power source marked “Class 2” or “LPS” and rated output 12 VDC,

minimum 0.2 A.

• Si le produit n’est pas fourni avec une source d’alimentation, il doit être alimenté

par une source d’alimentation certiﬁée UL de classe 2 ou LPS, avec une tension

nominale 12 Vcc, 0.2 A minimum.

• The installation must always be in accordance with the applicable provisions of

National Electrical Code ANSI/NFPA 70, article 725 and the Canadian Electrical

Code part 1, section 16. The power supply shall not be permanently ﬁxed to

building structure or similar structure.

• Cette installation doit toujours être en accord avec les mesures qui s’applique

au National Electrical Code ANSI/NFPA70, article725, et au Canadian Electrical

Code, partie1, section16. La source d’alimentation ne devra pas être ﬁxée de

façon permanente à une structure de bâtiment ou à une structure similaire.

• Power supply voltage polarity is critical. Incorrect voltage polarity can damage

the power supply and the unit. The ridges on the side of the cord (see ﬁgure 4)

identify the power cord negative lead.

• La polarité de la source d’alimentation est primordiale. Une polarité incorrecte

pourrait endommager la source d’alimentation et l’unité. Les stries sur le côté du

cordon permettent de repérer le pôle négatif du cordon d’alimentation.

• To verify the polarity before connection, plug in the power supply with no load

and check the output with a voltmeter.

• Pour vériﬁer la polarité avant la connexion, brancher l’alimentation hors charge et

mesurer sa sortie avec un voltmètre.

DVC RGB-HD A • Installation 7

ATTENTION:

• The length of the exposed (stripped) copper wires is important.

The ideal length is 3/16 inch (5 mm). Longer bare wires can short together.

Shorter wires are not as secure in the connectors and could be pulled out.

• La longueur des câbles exposés est primordiale lorsque l’on entreprend de les

dénuder. La longueur idéale est de 5mm (3/16inches). S’ils sont un peu

plus longs, les câbles exposés pourraient se toucher et provoquer un court

circuit. S’ils sont un peu plus courts, ils pourraient sortir, même s’ils sont attachés

par les vis captives.

• Unless otherwise stated, the AC/DC adapters are not suitable for use in air

handling spaces or in wall cavities.

• Sauf mention contraire, les adaptateurs AC/DC ne sont pas appropriés pour une

utilisation dans les espaces d’aération ou dans les cavités murales.

Securing the HDMI Connector Using the LockIt Cable Lacing Bracket

After connecting an input or output device to

an HDMI connector, secure the connector in

place with the provided LockIt bracket as follows:

1. Plug the HDMI cable into the panel

connection (

2. Loosen the HDMI connection mounting

screw from the panel enough to allow the

LockIt lacing bracket to be placed over it

(

3. Place the LockIt lacing bracket onto the

screw and slide it up against the HDMI

connector. Tighten the screw to secure the

bracket (

4. Loosely place the included tie wrap around

6. Configure the DVC as desired, using SIS commands (see Remote Configuration and

Control, beginning on page 11) or the PCS configuration program (see the program

help file).

EDID Minder

EDID information consists of the display resolution, refresh rate, data rate type, and video

format. EDID Minder maintains EDID communication to the connected source, ensuring that

the source continuously sees the EDID of a sink device, regardless of the input that is being

selected or is actually connected. You can assign a unique EDID file to an input, emulating a

sink device that has the desired characteristics.

The DVC has nine slots to which EDIDs can be assigned:

• VGA EDIDs (slots 1 through 7) — These factory-provided EDID files can be

assigned to slots 1 through 7 via SIS commands. Each EDID file contains a unique

native resolution. See the EDID Minder SIS commands on page 15 or the PCS

Configuration Software help file for more information.

• Output slot (slot 8, default EDID) — This slot contains the EDID of the connected

sink. When a sink is detected, this slot also detects the HDMI format EDID of the sink

and converts it to VGA format before saving it to the output slot. When the sink is

disconnected and power is cycled to the DVC, the EDID is removed from this slot and

replaced by the default EDID: 1280 x 720 @ 60 Hz. You can assign a different EDID to

this slot only via the PCS software (see the program help file).

• User-assigned EDID (slot 9) — This slot is available to import an EDID. The user slot

can be assigned only to the VGA input and initially contains the default VGA EDID. You

can assign an EDID to this slot only using the PCS software (see the program help file).

The following table shows the provided EDIDs and slot assignments.

DVC RGB-HD A • Remote Configuration and Control 11

Remote

Configuration and

Control

This section describes the connections through which the DVC RGB-HD A can be

configured and controlled remotely via SIS commands and the Product Configuration

Software (PCS), as well as the available commands and screen selections. Topics include:

• Communication Port

• Using SIS Commands

• Product Configuration Software (PCS)

• Firmware Loader

Communication Port

The DVC RGB-HD A can be remotely controlled via a host computer or other device (such

as a control system) that is connected to the rear panel USB Config port. With a USB

connection, you can configure and control the DVC using SIS commands or the PCS

software.

See Connecting for USB Control on page 8 to connect to the USB port.

Using SIS Commands

SIS commands consist of one or more characters per command field. They do not require

any special characters to begin or end the command character sequence. When the DVC

determines that a command is valid, it executes the command and sends a response to the

host device. Each converter response to an SIS command ends with a carriage return and

a line feed (CR/LF = ]), which signals the end of the response character string. A string is

one or more characters.

DVC-initiated Message

When power is cycled to the DVC (or at initial power-up) while the unit is connected to

the computer, the converter responds by sending the following message to the host. No

response is required from the host.

20nn is the year, and Vn.nn is the firmware version number.

DVC RGB-HD A • Remote Configuration and Control 12

Error Responses

When the DVC receives a valid command, it executes the command and sends a response

to the host device. If the unit is unable to execute the command because the command

contains invalid parameters, it returns an error response to the host. The responses include:

• E01 — Invalid input number

• E10 — Invalid command

• E13 — Invalid parameter

• E14 — Not valid for this configuration

• E17 — Invalid command for signal type

Using the Command and Response Table

The Command and Response Table for SIS Commands, beginning on page 15, lists

the commands that the DVC RGB-HD A converter recognizes as valid, the responses that

are returned to the host, a description of the command function or the results of executing

the command, and command examples.

NOTE: If the unit does not support or recognize a command that is entered, no action is

taken and no response is returned.

X#X# = Verbose mode

0 = None

1 = Verbose mode (default)

2 = Tagged response for queries

3 = Verbose mode and tagged response for queries

NOTES:

• In verbose mode, the DVC responds with unsolicited responses for value and

setting changes that may result from a signal change, or a setting adjustment made

via another interface.

For example, the DVC can send out a notice of a change in some setting without

receiving a query via your PC. That change could have been a result of an internal

process or a power cycle. This is an example of a verbose (wordy) relationship

between the controller and a connected device.

• If tagged responses are enabled, all “view” commands return the command string

plus the data, the same as in responses for setting a value. For example, for the

View EDID assignment command:

Command: E AEDID }

Response: EdidA X$ ] (tagged response)

or X$ ] (untagged response)
