7

The ADV2.1 supports two DVI video inputs, each paired with digital audio
connections. The DVI inputs support the full 165Mhz maximum clock rate of the
DVI Single-Link Specification allowing it to work with all HDTV signal sources and
up to 1600x1200 graphics resolution. Since the DVI standard is fully digital, all data
is passed flawlessly through the ADV2.1.

Controls

The unit includes a seven-button custom remote control, as well as controls on
the unit itself, that allow the user to switch easily between up to two DVI
sources. The ADV2.1 is also programmed with the ability to learn new codes
from other remote controls for executing all of its functions.

RS-232 Communication Port

Aside from standard audio/video inputs on the rear of the unit, the ADV2.1
includes a RS-232 communication port as an optional way of controlling the
unit. It interfaces well with system controllers, such as those made by Crestron
and AMX, or it can be connected to a home PC and issued commands via a
terminal program, such as Microsoft HyperTerminal. All the features accessible
through the remote control are also accessible via the RS-232 communication
port. For detailed technical information, please see Appendix B on
pages 18-19.

DVI Video Connections

The ADV2.1 is designed to switch standard single-link DVI video signals, an
application shown on page 7. It is compatible with HDCP.

- To connect, attach a standard DVI cable with male ends to both the
source equipment and the chosen ADV2.1 input.

- To connect the output of this unit, connect a standard DVI cable with male
ends to the output connector on the ADV2.1 and to the chosen input of a
DVI video receiver (TV, projector, A/V receiver, etc.).

- (NOTE: The technical limitations of a standard DVI interface limit the
cable length to a range of approximately 5m to 10m at the highest signal
rates. Therefore, DVI cables longer than 15 feet (5m) may not work at the
highest allowable DVI signal rates depending on the specific hardware on
the source and receiver ends of the cable and the cable quality. Lower
signal rates, such as those used for HDTV formats of 480p, 720p and
1080i, can sometimes utilize cables longer than 5m to 10m. See
Troubleshooting on pages 14-15 for more information.)

Digital Audio Connections

In addition to video signals, the ADV2.1 can be used to simultaneously switch
digital audio signals

- Digital audio may be connected using either digital coax (SPDIF) or
optical (Fiber) formats. The chosen output from the digital audio source is
simply connected to the chosen ADV2.1 digital audio input through the
proper cable type.

- Coax and optical formats transmit the same data over different media, so
if a source has both types of outputs the user may choose whichever is
more convenient.

- Never connect both a digital coax cable and an optical cable to the same
input number at the same time. Data errors will likely result. However,
both types may have their outputs connected simultaneously if desired.

- (NOTE: For the coaxial digital audio connections, 75-ohm digital audio
cable should always be used. Other types of cable cannot be used reliably
in all situations.)

LED Display Dimming

The ADV2.1 provides the option of adjusting the LED brightness to best suit the
viewing environment. There are 10 different dimmer settings available with setting
0 being the brightest and most intense and setting 9 being the dimmest and least
intense. When a dimming level is selected, the green LED on the front panel will
reflect the chosen level immediately and that setting will be saved in the ADV2.1
until it is changed.The LED display brightness can be adjusted through the RS-232
communication port or by using the remote control in conjunction with the input
selector button on the front panel.

Using the Remote Control and the Input Selector Button

- While pressing the input selector button on the front panel, point the
remote control toward the unit and press the

+ key to increase the
intensity of the LED display, or the – key to decrease the intensity of the

Operations

Using an Alternate Remote

The ADV2.1 comes preprogrammed to recognize command codes from the
supplied AVLinx remote control. An alternate remote can be used in place of the
supplied remote. The original AVLinx remote control can be used to program most
universal remote controls by following the instructions for that product. Universal
and pre-programmed remote users may also choose to teach the ADV2.1 a new
set of pre-programmed codes. A small sample list of compatible manufacturers’
codes is listed in Appendix A on page 18. Please consult your universal remote
documentation on how to set pre-programmed codes. When an alternate remote is
configured with a suitable pre-programmed code set, the AVLinx remote functions
can be assigned to the alternate remote by performing the following steps:

Programming Input Selector Keys

1. Turn on the unit.

2. Make sure there are no other infrared remote control signals interfering
with the unit during the programming process.

3. Press and hold the

input selector button
on the front panel for

5 seconds until the
LED turns on.

4.

While continuing to
hold the front panel
button,

aim the
supplied AVLinx
remote directly at the
IR sensor window
and press the key
you are reassigning.

5. If the unit
recognizes that
command, the active
input’s green LED
will turn off briefly
then come back on.

6.Aim the new remote
that is to be used for
programming directly
at the IR sensor
window and press
the key that will be
performing the
desired function.

7.If the unit recognizes the command on the new remote, the active
input’s green LED will blink twice to confirm that the unit has set the new
key code.

Appendices Appendices

Appendix A: Compatible Remote Control Format

The following are products whose remote control data format is compatible with
the ADV2.1. The format used by the ADV2.1 is the NEC type with a 38khz carrier
frequency. Many universal or multi-function remote controls are able to be
programmed to emulate the remote control codes from these products. By
configuring your system remote to transmit codes from these products, and
following the steps in the section “Using an Alternate Remote Control” on pages
11-13 to teach your ADV2.1 the new codes, the ADV2.1 will work with many of the
remote controls you already have. This is very advantageous to those with a
master system remote control or those wanting to reduce remote control by
consolidating functions onto fewer remotes. These products are a very small
sample of those whose data format can be recognized by the ADV2.1. Other
settings may be tried, and the default ADV2.1 codes may always be restored by
following the instructions in “Restoring Default Remote Control Codes to the Unit”
on page 13.

Appendix B: RS-232 Communication Port

The RS-232 port on the ADV2.1 can be used to control all aspects of the unit
including changing inputs, changing the power state, querying the input and power
states, and reading its firmware revision information. The RS-232 USART* on the
ADV2.1 operates at 9600 baud, 8 data bits, 1 stop bit, and no parity bits, which
means that the unit issuing commands must be configured with those settings as
well. All commands issued to the unit should be terminated with a carriage return.
All responses from the unit are terminated with a carriage return followed by a line
feed.

When the power cord is connected to the ADV2.1 (regardless of the power on or off
state), the RS-232 communication port will send the code “AS<cr><lf>” to
acknowledge that the unit’s startup sequence has completed. Once this response
has been received from the ADV2.1, the unit is then ready to perform all functions.
See the following table for a listing of available commands and their arguments.

All commands that do not have some form of default response are acknowledged
with an ‘A’ followed by the associated command character from the table below.
The ADV2.1 has a verbose mode, which is disabled by default, that provides the
status of the input and power state every time the state changes. It is equivalent to
issuing a Get command to return status information.

All RS-232 command
execution is inhibited while the front input selector button is pressed. All received
RS-232 data will be processed when the selector button is released as long as the

1 command receive buffer does not overflow.”

*Universal Synchronous Asynchronous Receiver/Transmitter

ADV2.1 Recognized RS-232 Commands

The RS-232 communications port will issue an error for the following situations.
The error will consist of ‘E’ followed by a decimal number and a carriage return and
line feed.

E2 – Command not valid
E3 – Argument (second character) for received
command not valid
E6 – RX buffer overflowed
