1.0 General
Thank you for purchasing Black Box AC1032A-4A 4-Port DVI Switch
with Audio & Serial Control.
This unit provides both a video and audio output that can be switched
between four video and audio sources. This allows routing of multiple
DVI equipped devices (such as PC’s) to a single DVI display (such as a
plasma or LCD screen). The switcher supports single-link, DVI-D video
signals at resolutions up to 1600x1200 and HDTV up to 1080i.
The AC1032A-4A unit provides all the A/V and control connections on
the rear panel; the front panel has a push-button switch with
corresponding LED indicator for the selection of video source.
This unit can be controlled by either manually using the front panel
switch, automatically based on video detection, or remotely through an
RS232 serial port.
The unit can be configured to operate in three different modes, which are
the Auto, Scan and Manual modes.
The unit also has EEPROM (internal non-volatile flash memory) to store
the last operating mode when power is off.

3.0 Installation
3.1 Required Cables
The video input cables are generally DVI male to male (customer
furnished). The Audio inputs are 3.5 mm mini-stereo (customer
furnished). To connect to the unit to a Serial port (such as PC’s COM1)
you would need a Male/Female DB9 Serial Cable (customer furnished).
All of these items are available for purchase upon request.
3.2 Inputs & Outputs
The AC1032A-4A has 4 video and audio inputs labeled ‘Video 1’
through ‘Video 4’. The unit has 1 video and audio output labeled ‘Video
Output’.
3.3 Connecting the AC1032A-4A
Connect your video and audio sources such as computer or notebook PC
to ‘Video 1’, ‘Video 2’, ‘Video 3’ and/or ‘Video 4’ connector(s).
Connect the display device such as a monitor (or a video projector) to the
switched video and audio output connectors.
Connect the included power supply to the AC1032A-4A.
Select the desired mode of operation (Auto, Scan or Manual) using the
front panel switched buttons. (Auto = SEL 1 & SEL 2, Scan = SEL 3 &
SEL 4)
If preferred, the above selections (and more) can also be done through
RS-232 serial commands by connecting a DB9 RS-232 Serial cable to
your PC and the AC1032A-4A.
The device can be mounted via a Universal Mounting Bracket (sold
separately) if desired.

4.0 Operation
4.1 Manually Switched Output
The SEL1 through SEL 4 buttons are used to select between video &
audio input sources of Video 1 through Video 4. A solid-on LED is used
to indicate which input is selected.
Holding down any of the SEL buttons for 3 seconds will blank that
selected input source (and mute the audio output). The LED for that
selected input will start blinking to indicate the blanking mode. Pressing
that SEL button again will un-blank the output and un-mute the audio on
the Video Output rear connector.
MODEL AC1032A-4A FRONT PANEL
4.2 Modes of Operation
The unit can operate in either Auto or Manual mode. Pressing the SEL 1
and SEL 2 buttons simultaneously for 3 seconds will select AUTO mode.
Pressing any SEL button selects MANUAL mode.
When in Auto mode, the SEL 1 and SEL 2 LEDs will flash to indicate the
mode is active.
In Auto mode, the AC1032A-4A will automatically select the input with
active video and audio. The presence of video is determined by
examining the V. Sync signal or optionally the +5 VDC signal from DVI
input connectors. The front panel SEL buttons cannot be used to switch
between ‘Video 1’ through ‘Video 4’ sources in this mode. Pressing any
of the SEL buttons will take the unit out of AUTO mode.
In Manual mode, the output of the AC1032A-4A will depend on the
selection of the SEL buttons.

4.3. Priority Selection in Auto Mode
The priority of the Video 1 through Video 4 inputs can only be selected
by a command through the RS232 port.
This priority selection only applies to Auto mode. If a video priority is
selected, the AC1032A-4A will automatically select that ‘Video' input
whenever it detects the presence of a video signal at that ‘Video’
connector, regardless of what is happening at the other ‘Video’
connectors. A priority value can be set for all four ‘Video’ input
connectors.
For example, the priority has been set for ‘Video 2’, ‘Video 4’, ‘Video 1’
and then ‘Video 3’. If the ‘Output’ is playing the video & audio from
‘Video 3’ and video from ‘Video 1’ is detected, the output of the
AC1032A-4A will change to select ‘Video 1’ video immediately. Video
detection on either ‘Video 2’ or ‘Video 4’ would take precedence over the
‘Video 3’ signal..
4.4 Long Cable Equalization
The use of long DVI cables can cause the ‘Video’ image to degrade to
unacceptable levels. Enabling the ‘BOOST’ signal, can sometimes
compensate for the cable length and produce an acceptable picture.
The ‘BOOST’ setting can only be selected by a command through the
RS232 port.
4.5 Scan Mode
The unit can operate in Scan Mode by pressing the SEL 3 and SEL 4
buttons simultaneously for 3 seconds.
When in Scan mode, the SEL 3 and SEL 4 LEDs will flash to indicate the
mode is active.
In scanning mode, the unit will display each of the video and audio input
signals for a pre-determined time period from 1 to 60 seconds.
The unit can also be programmed (via the RS232 port) to scan only
active video inputs or even inputs without a video signal.

4.6 RS-232 Control Port Usage
The AC1032A-4A can also be controlled via a serial device. The unit
operates at a baud rate of 4800 bps. From the serial port, you have full
control over the operation of the switched output, mode, and priority
buttons.
The AC1032A-4A will output a menu to the serial port on power-up. This
menu can also be displayed when the appropriate command is sent to the
AC1032A-4A via the serial port. To view the menu, an ASCII serial
terminal or terminal emulator software is needed. An example is
Microsoft Windows HyperTerminal (generally found in the Accessories
-> Communication folder)
4.7 To configure HyperTerminal
-
Connect direct to any available COM port
4800 Baud, 8 bits, No Parity, 1 Stop bit, No flow control
Settings per following figures:
After power-up the unit will output the following menu in ASCII through
its serial port:
MENU - Version 1.0
----------------------------------------1 = Video 1 Input | B = Blank
2 = Video 2 Input | U = Un-blank
3 = Video 3 Input | E = Enable boost
4 = Video 4 Input | D = Disable boost
A = Auto mode
| R = Report
S = Scan mode
| F = Factory defaults
P = Priority
| M = Menu

DVI Switch
ASCII ‘S’ or ‘s’ (Hex 53/73 or Decimal 83/115 )
Enters Scan Mode
If the unit was already in SCAN mode, the unit will respond
with the message:
Scan mode already selected
The user must select the desired scan time by entering a
number from 1 to 60 within 20 seconds. Entries outside
this range or delaying entry longer than 20 seconds will
result in a default setting of 5 seconds.
The device will respond with:
Scan mode selected
Please enter ‘time between switching’ (1-60 sec):
After the entry (or timeout), the device will respond with:
Scan non-active video? (y/n)’
Again the user must respond within 20 seconds.
Entries other than ‘Y’, ‘y’, ‘N’ or ‘n’ or delaying entry longer
than 20 seconds will result in an error message
corresponding to the last setting of the SCAN mode.
Invalid input! Scan only active video
Invalid input! Scan all video
In scan mode, the unit will display each of the video and audio
inputs for the selected time period. If the device was told to
scan non-active video inputs and no video is available on that
input, a black screen will be displayed for the selected time
period.

5.3 Problem Solving FAQ
1.
What are the Cable Length Limitations?
The switcher cannot be used as an extender. Therefore it is best to
plug the output of the switch directly to the display device and use
input cables that are 5 meters (16 ft) maximum. In other words, try to
keep the total length of cables from the video source to the box and
from the box to the monitor should not exceed 16 feet. At longer
distances you may experience video degradation. If you cannot use
shorter cables, try to set the refresh rate and/or resolution of the video
signal to a lower level.
