Wiring the Power Connector for the connection procedure.
BHDMI 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).
CConfig port — Use a USB A-to-mini B cable to connect this port to a USB port on the

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 (1).
2. Loosen the HDMI connection mounting
screw from the panel enough to allow the
LockIt lacing bracket to be placed over it
(2).
3. Place the LockIt lacing bracket onto the
screw and slide it up against the HDMI
connector. Tighten the screw to secure the
bracket (3).
4. Loosely place the included tie wrap around

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.
©Copyright 20nn,Extron Electronics DVC RGB-HD A, Vn.nn,60-1614-01 ]
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.
