As the ideal peripheral for all Barco digital cinema installations, ACS-2048 is an 8 x 1 video
switcher that accepts "universal" input formats, and outputs up to 12-bit DVI at 2048 x

1080. With a high-quality scaler at its core, upconverting any input format is as simple as
"auto-acquiring" and selecting the desired input. However, disguised as a switcher, ACS­2048 is a pathway to new revenue streams for your facility. By enabling "alternate" content
to be displayed in the digital cinema resolution, your theatre's role as a presentation facility
for events, businesses, conventions and so much more — becomes a reality.

Please note:

• To ensure trouble-free installation and operation of your ACS-2048, please follow

all procedures in the following two sections:

~ Chapter 3, “Installation” on page 25.
~ Chapter 4, “Operation” on page 31.

• Should you have any questions regarding the installation or operation of the ACS-

=system, please consult with the factory. Refer to Appendix C, “Contact

2048

About the ACS-2048

^=tçêÇ=^Äçìí=ea`m

HDCP stands for High-Bandwidth Digital Content Protection, an industry-wide copy
protection scheme that is used to prevent the potential interception of digital data between
the source (e.g., a Blu-Ray player) and the target display (e.g., a digital cinema projector).
The HDCP format was designed by Intel, and it uses an “authentication and key exchange”
procedure to accomplish the required protection. For proper implementation, products that
are compatible with the HDCP format require a secure connection to a compliant display,
such as a digital cinema projector.

In digital cinema applications in which an ACS-2048 is used, when an HDCP compliant
device is connected to the ACS-2048, an HCDP “session” is created. In this session
(which is transparent to the user), “keys” are exchanged between the source device (e.g., a
Blu-Ray player) and the digital cinema projector. The source device queries the display to
ensure that the equipment is HDCP compliant before video is shown. Note that non-HDCP
equipment such as PCs will work with any DVI compliant display, but HDCP compliant
equipment only shows content on HDCP compliant displays.

Please note the following important points:

• When an HDCP compliant device is connected to the ACS-2048 and that specific

input is selected, the Status Menu indicates if HDCP is enabled.

• If the “session” determines that the target display device is non-HDCP compliant

(e.g., if the user is attempting to make an illegal copy on an external recorder), an
error message appears on the ACS-2048’s Status Menu, indicating that video
cannot be shown.

• HDCP compliant repeaters cannot be connected to the output of the ACS-2048,

as the ACS-2048 must be the last device in the HDCP "chain" — prior to the
HDCP compliant display device (projector). If an HCDP repeater is connected,
the message “HDCP Violation” appears on the Status Menu. Refer to the
“Status Menu

” section on page 67 for additional details.

Please note the following important menu rules and conventions:

• The top line names the current menu, in all capital letters.

• Subsequent lines typically display two fields:

~ For a listed function, the left-hand field names the function, and the

right-hand field is the function’s current parameter (or value).

~ For a listed sub-menu, the left-hand field names the sub-menu that you

can access, and the right-hand field displays the double arrow (>>),
indicating that a sub-menu is available.

• The “navigation” cursor (>) in the left-hand column indicates the current line on

which action can be taken. This arrow “scrolls” as you rotate the knob.

• Scrolling:

~ Turn the ADJUST knob counter-clockwise (CCW) to scroll down.
~ Turn the ADJUST knob clockwise (CW) to scroll up.

• To enter a sub-menu, scroll to the desired line and press SEL.

Note

Throughout this chapter, the term “select” is used as an
abbreviation for “scroll to a selected menu line and press the
SEL button.”

S Select the Input field to ...

• To change a parameter, scroll to the desired line and press SEL. The cursor

changes to the “edit” cursor (#). Use the ADJUST knob to modify the value:

~ Turn the ADJUST knob CW to increase a value.
~ Turn the ADJUST knob CCW to decrease a value.

• To accept a p ara mete r or val ue, press SEL. The edit cursor changes back to the

navigation cursor.

Note

You must press SEL to activate an ACS-2048 function.

• In the “edit” mode, to exit (or cancel) without changing the origina l parameter,

4. Operation

Using the Main Menu

fе=^мнз=^ЕимбкЙ

From the Main Menu, select In Auto Acquire to enable or disable the Input Auto Acquire
mode. Values are: OFF and ON (default).

Please note the following important points:

• When In Auto Acquire is ON, the system always performs a full sync acquisition

on the selected input signal under the following conditions:

~ When an input channel without a saved configuration file is selected.
~ When the input type is changed.
~ When the input signal changes sync rates.
~ When an input with a saved configuration file is selected, but the input

timing is different from the saved configuration.

• When In Auto Acquire is OFF, the system first uses the “associated” input file

configuration for each input channel (to the greatest extent possible). At some
point, the input signal may be too far away from the saved configuration, in which
case a good input lock may not be possible.

• It is recommended that you leave the In Auto Acquire mode ON. In this mode, if

the timing changes on any of your inputs (whether or not you have a saved
configuration file), you will always get an output image. On the other hand, if the
mode is OFF and the timing of an input changes, the output will be black.

• When the In Auto Acquire mode is ON, the ACS-2048 automatically detects and

acquires the input video type and resolution (in most cases), and limits menu
selections as applicable to the detected video type (e.g., color space).

• If you are an advanced user and you know the exact timing parameters for your

input(s), you can turn the In Auto Acquire mode OFF , and dial in your timing parameters manually.

Tip

Refer to the “Understanding Auto Acquire

If you have already saved configuration files for your input
sources, it is recommended that you turn the In Auto
Acquire mode OFF. This mode provides the fastest
transition times. When the mode is ON, transition times will
be greater, due to the additional time required to analyze the
input timing for each selected source.

Figure 4-9. Image Adjust Menu (sample)

• Select Auto Config to perform an automatic input configuration on the selected

source. In this mode, the system finds the first and last pixel on each edge, and
ensures (to the best possible extent) that the entire image is visible. In addition, if
the input is analog, the system automatically phases the input to determine the
correct sampling phase.

• Select H Crop to crop both the left and right edges simultaneously. Values are in

pixels. The output “window” is maintained in both size and aspect ratio.

• Select V Crop to crop both the top and bottom edges simultaneously. Values are

in lines. The output “window” is maintained in both size and aspect ratio.

Note

For both H Crop and V Crop, the function always cuts into
the visible image, and never exposes any video outside the
source’s active area. In addition, as you crop, the ACS-2048
always scales the input back up to fit the selected aspect ratio
within the system’s 2048 x 1080 output window.

• Select H Pan to pan a cropped image left and right — within the selected aspect

ratio. V alues are in pixels. Note that the value reads [0] if the image has not been

source.

Note

Tip

In this mode, for the selected image, the system finds the first
and last pixel on each edge, and ensures (to the best
possible extent) that the entire image is visible. In addition, if
the input is analog, the system automatically phases the input
to determine the correct sampling phase.

Ensure that there are non-black pixels around the extreme
edges of your active video, in order for the image to be
properly sized by the Auto Config function. For example, if
you use a Windows desktop with a high luminance
background, the Auto Config function will be accurate. If, on
the other hand, you use a desktop image with a black border,
the image will not be properly sized.

• Sampling — select this function to change the sampling for the selected input.

Available values are: Oversample and 1:1 (default). Please note:

~ When 1:1 Sampling is selected, the system provides pixel-for-pixel

sampling, and generally better image quality.

~ When Oversample is selected, the system performs multiple samples

for every pixel, with a resulting “softer” image.

~ Oversample is only available for RGB and YP

analog inputs.

bPr

~ All other input types have defined sample clocks that are inherently 1:1.

If the input is set to one of the other types, the value is [1:1].

• Sample Phase — This selection is only available when Sample Mode is 1:1 and

the input is analog RGB or YPbPr. If Oversample is selected, the field is hidden.
The sample phase value is initially filled in by the Auto Config command, or set to

the default value. You can further fine-tune the image by adjusting the sample
clock phase directly.

~ Adjustment range: -16 to 15
~ Default: 0

For all Horizontal “active area” fields, all units are measured in pixels:

• H Total — adjusts the total pixel count per line. This value cannot be adjusted if

the input type is DVI / SDI.

• H Position — adjusts the offset of start of active area from H sync.

• H Active — sets the size of the active area.

For all Vertical “active area” fields, all unit are measured in lines.

• V To tal — indicates the total line count per frame. This value is measured, and

can never be adjusted. Its value will always be shown in brackets.

• V Position — sets the offset of start of active area from V sync.

• V Active — sets the size of the active area.

EDID (Extended Display Identification Data) is a VESA standard data format that contains
information about a display device and its capabilities, including the preferred (as well as
the allowed) device resolutions.

The ACS-2048’s EDID file is stored in non-volatile memory. This file is read by a
computer's DVI graphics card during boot-up, when its DVI output is connected to a DVI-I
input connector on the ACS-2048 system (inputs 2 and 3). The ACS-2048 must be
powered on first for the EDID information to be read.

This menu is designed for advanced users only. Do not
reprogram EDID unless it is necessary.

• Off — indicates that sync has not been detected on the input connector, and the

input cannot be used on air. The input is invalid.

• Dim Yellow — (or backlight on) indicates that sync has been detected, and the

source is available (valid) for use on air. The input is valid.

• Bright Yellow — indicates the currently selected “on air” source.

• Blinking — indicates that sync has been lost from the current “on air” source. In

this situation, internal “black” will automatically replace the previous on air source,
and the source cannot be used on air until sync is restored.

fеймн=pЙдЙЕнбзе=oмдЙл

Please note the following important points regarding the Auto Acquire mode:

• If In Auto Acquire is ON and a valid input is selected that does not have a saved

input configuration file associated with it, the system attempts to acquire the
source, save an input configuration file, and smoothly transition to the new source.

Note

Two different error messages can be displayed when In Auto Acquire is ON:

The input configuration file will only be saved if the "Auto
Input Save" mode is ON in the User Preference Menu.

~ Mismatch: The ACS-2048 cannot match to any saved input

configuration, or to any format in the input format table.

~ Invalid Signal: No valid input signal is detected.

• If In Auto Acquire is OFF and a valid input is selected with a saved input

configuration file, the system compares the library file to the input’s timing.

~ If the timings match, the system transitions to the input.
~ If the timings do not match, the system displays black and the “Invalid

Signal” message appears.

Three error messages can be displayed when In Auto Acquire is OFF:

~ Mismatch: The ACS-2048 cannot match to any saved input

configuration, or to any format in the input format table.

~ Invalid Signal: No valid input signal is detected. In this situation, the

video output will be black.

~ No Saved File: A configuration file has not been saved for the input.

• When a new (unsaved) input is selected, the system performs one of three “auto

acquire” sequences, depending on the current system condition:

~ Condition 1: No source is currently selected, and the output is black.

This condition occurs after a factory reset.

• When you select a new source, the system transitions to the
source — once the “auto acquire” is complete.

70 ACS-2048 • User’s Guide

~ Condition 2: A source is currently showing on the output.

~ Condition 3: A test pattern is showing on the output.

TEST

PAT

There are two ways to use the button:

• When TEST PAT is pressed, the button lights, and the internal test pattern is

routed to the output. When you select another input, the system transitions to the
new input.

• When the TEST PAT button is already lit, press the TEST PAT button again to

toggle back to the last selected input.

4. Operation

Using Test Patterns

• When you select a new source, the system transitions to black.
Once the “auto acquire” of the new source is complete, the
system transitions to the source.

• When you select a new source, the system transitions the test
pattern off, and then follows the rules outlined for conditions 1
or 2 — depending on the current situation.

Note

Please note the following important points regarding test pattern usage:

If the Menu Context mode is ON in the User Preference

Menu, the Test Patterns Menu appears whenever the TEST
PAT button is pressed, allowing you to select an internal test

pattern and adjust additional test pattern parameters.

• When Menu Context is ON and TEST PAT is pressed, the last selected test

pattern is automatically enabled, and the Type field is selected, enabling you to
change patterns easily.

• If you need to change the state of the Raster Box in this mode, press ESC, scroll

to the Raster Box field, and change the function as required.

• Regardless of the Menu Context mode, pressing TEST PAT has no effect on the

state of the Raster Box. It always remains in its last selected mode.

This appendix provides information regarding remote control protocol. The following
topics are discussed:

• Communicating with ACS-2048

• Command Protocol

• Error Codes

• ACS-2048 Command List

• Remote Commands

`зггмебЕ~нбеЦ=пбнЬ=^`pJOMQU

 Use the following steps to communicate with the ACS-2048 via Telnet:

1. Connect the ACS-2048’s Ethernet port to an Ethernet switch, and connect the
switch to your PC or laptop.

2. Ensure that all Ethernet parameters are properly set up. In Chapter 4, refer to the
“Ethernet” section on page 58 for details.

3. For Telnet communications, use the ACS-2048’s IP address and port 23. On a
Microsoft Windows PC, open a command prompt window and enter the following:

> telnet xxx.xxx.xxx.xxx 23

4. After you “Telnet” into the ACS-2048, you are presented with the login prompt:

Welcome to ACS-2048.
Login as “user”.
Press <ENTER> for password.

a. Type “user” and press ENTER to login.
b. When prompted for a password, simply press ENTER.

Once you have successfully logged in, the following message appears, along with
the command prompt (>):

ShellApp waiting for input
>

5. You can now issue commands. Operationally, the telnet window functions in a
manner similar to a serial communications session. As required, type "help" to
see a list of supported commands.

Refer to the “Remote Commands

” section on page 98 for a complete list of commands.

ACS-2048 • User’s Guide 93

_K==oЙгзнЙ=`зенкзд=mкзнзЕзд

Command Protocol

`згг~еЗ=mкзнзЕзд

The ACS-2048’s command protocol is compatible with GNU getopt parsing. Every
parameter of the command has an option character associated with it. A <CR> carriage
return (ASCII 13) terminates the command.

Note

The order of the option characters in the command does not
matter.

S Command example:

ITYPE -i 2 -t 1<CR>

Or

ITYPE -t 1 -i 2<CR>

`згг~еЗ=oЙлйзелЙл

A command response is sent after each command is processed. This response consists of
the command, followed by the error code, a line feed <LF> and a special termination
character (\x4).

• When a command is successful, the error code is a 0 (eERR_OK), or some

positive value.

• When a command is not successful, the error code is a negative value. A

preliminary list of the error codes is included. Refer to the “Error Codes
on page 96 for details.

S Command response example:

ITYPE -e 0<LF>
</x4>

” section

nмЙку=lйнбзел

Query type options are available for the commands. The order of precedence for
processing query option arguments is help (--help), query (-?), and list (--list). If more than
one query option is sent in a command, the option with the highest precedence is
processed, and any others are ignored.

Help Query — Commands have a “help” query option associated with them, (--help). This
query lists all option flags and parameters for the command in the following format:

S Help option example:

IBRT --help<CR>

S Response:

f_oq

• Description: Input Brightness Adjust

• Command Format: IBRT -i(input) -b(bright)

94 ACS-2048 • User’s Guide

_K==oЙгзнЙ=`зенкзд=mкзнзЕзд

Command Protocol

• Parameters:

-i(input): Input number, 1-8

-b(bright): 75.0%-125.0%

• Query Format: IBRT i(input) -?

• Query Response: IBRT i(input) b(bright) --min 75 --max 125

IBRT -e 0 <LF>
</x4>

Current Setting Query — The current setting query option (-?) returns the command with
each of the current parameter settings. Commands with minimum and maximum settings
for the parameter will have these “min” and “max” values returned with option flags --min
and --max.

S Query option example:

IBRT -i 4 -?<CR>

S Response:

IBRT -i 4 -b 100.00 --min 75 --max 125
IBRT -e 0<LF>
</x4>

Several commands have a list for the associated valid parameter values, such as the
format commands. The list of these values can be queried with the list query option (--list).
The list shows has the numeric value for the parameter, followed by the value text encased
in quotes. A colon separates the numeric value from the string.

S List query option example:

ISMP -i 4 --list<CR>

S Response:

0:"OverSample"
1:"1:1"
ISMP -e 0<LF>
