8x8 and 16x16 VGA / HDTV Matrix Switch with Audio, RS232 & IP Control
About This Manual
This user’s manual covers several variations of Black Box’s 8x8 and 16x16
VGA/HD matrix switches. Five configurations of the matrix are discussed in this
user manual per the table below. Since this is an all-encompassing user’s manual,
portions of this guide may not pertain to any specific unit.
AC1120A
8x8 VGA Matrix Switch With Serial Control
AC1121A
8x8 VGA & Audio Matrix Switch with IP and Serial Control
AC1122A
16x16 VGA Matrix Switch with Serial Control
AC1122A-RJ45
16x16 VGA to RJ45 Output Matrix Switch with Serial Control
AC1123A
16x16 VGA & Audio Matrix Switch with IP and Serial Control
*** Upon power-up, the switches output a string on their RS-232 port that
identifies the unit’s capabilities such as "BBox-I-A-8-8" (I=IP port, A= Audio,
8-8 = number of inputs and outputs respectively) There is also a command
(RI) for reading the identity of the switch.
1.0 General
The AC1120A through AC1123A are compact high-end matrix switches for video
and audio. The matrices are used for cross-point switching of video and audio
signals. The switch provides 8 or 16 video (and audio) outputs, each capable of
independently displaying any of 8 or 16 inputs in any combination. Additionally,
the outputs can be blanked out and/or muted. The Matrices can be used in TV
broadcasting environments, multi-media conference halls, public facilities, large
display projects, schools, courtrooms, and command & control centers.
The units are compatible with PC video from 640x480 to 1920x1600 or analog
SD/HDTV Component Video (YPbPr) from 480i to 1080p. The Matrix can be
controlled in three ways: manually using the buttons on the front panel, through
one or two serial RS232 control ports, or remotely via IP port.

control, and the power connections are on the rear of the unit.
Figure 1 – Rear panel of AC1123A showing all the connections
2.1 Input Audio & Video Connections
Below the input connections are described first for standard units (those with
HD15 connectors) and then for units having RJ45 inputs. Please keep in mind that
some of the following information may not apply to every matrix switch.
2.1.1 AV Inputs on standard unit
Figure 2 - Audio and video inputs on AC1123A
6
8x8 and 16x16 VGA / HDTV Matrix Switch with Audio, RS232 & IP Control
2.1.1.1 Video Inputs
The video connectors on the basic unit are HD15 female. These are compatible
with PC’s VGA video signal (RGBHV). The Matrix is also compatible with
analog SD or HDTV signals (YPbPr) with resolutions from 480i to 1080p. To
connect these types of signals to the Matrix, HD15 to 3-RCA cables may be
required.
Technical Note about the Video Inputs
The HD15 inputs of the matrix handle only the color and sync signals. EDID
(extended display identification data) is absent. EDID is normally used by the
source PC to read pertinent information from the connected display. This
information includes a list of the resolutions that are supported by the LCD. If
EDID is not implemented, the source PC is unaware of the specific LCD
connected to it. Generally this is not a problem since in the absence of EDID,
most PC’s allow the user to select from a set of default resolutions for output.
Some PC’s may not output any video signal, or only allow limited resolution
settings with the absence of EDID . One way to resolve this is to change the
display settings of the PC to show all modes and not detect Plug and Play
LCD. The procedure for doing this varies depending on the operating system
and the video card in the PC. It is generally found under: Control Panel >
Display Settings > Advanced > Monitor tab.
An alternative method is a hardware solution which does not require any
changes to the PC’s display settings. Black Box manufacturers EDID emulators
that are constructed as simple HD15 pass-through adapters. Inside, they
emulate an LCD’s EDID supporting a wide range of 4x3 and 16x9 PC
resolutions. These EDID emulators are sold separately.
2.1.1.2 Audio Inputs
The audio input on the basic unit uses standard 3.5mm mini-stereo connectors. To
use these with PC audio, standard male-to-male audio extension cables would be
required. To connect from typical TV sources with separate right and left
connectors, 3.5mm male to 2 RCA cables would be needed. For mono audio, then
the tip of the 3.5mm connector (tip=left channel) should be used.
Technical Note about the Audio Inputs
Since the audio inputs are unbalanced (single ended), the ground reference of the
source has to be the same as the matrix. Of course the cable connecting the two is
tying the grounds across but if there are currents flowing in the ground it can create
potential differences that would manifest as noise. The quality of grounding at the
audio source and the matrix are important. For example if the input source is a
desktop PC, as long as the PC is properly grounded and the audio cable length is
not excessive, you can expect good results. On the other hand if the input is a
notebook PC running on battery, there is no ground reference at the source so it gets
its reference through the audio (and video) cable connection to the matrix. This
should also be okay. However if it is plugged in through its external power brick,
noise can be induced. This is because most notebook power supplies do not
properly provide an AC ground path to the system ground (some only have only 2
prong AC cords). The switching power supply circuit will inject noise into the audio
lines. In this case the solution may be to attach a low resistance ground strap to the
notebook. The other option for eliminating the noise is to use a stereo audio Balun
(or isolator). The Balun essentially couples the audio through a transformer so the
audio grounds are isolated. Baluns can also cure noise pickup in long cable runs.

2.1.2 Audio Inputs on units with RJ45
Two types of RJ45 input configurations may be possible. Please contact Black
Box for availability and delivery information. The model number designates the
input either as RJ45 with power or RJ45 with Audio.
2.1.2.1 RJ45 input with Video and Power
The RJ45 with power units are compatible with Black Box AC504 and AC602
series of senders. The Matrix can also send power to one channel senders via the
Cat5 cable so that no external power supply would be needed.
2.1.2.2 RJ45 input with Video and Audio
The RJ45 with audio units are compatible with Black Box AC154A series of
senders. These senders transmit VGA video and audio to the matrix. The audio is
received as a balanced signal and is immune to noise pickup or ground noise.
2.2 Output Audio & Video Connections
The output connections are described below first for standard units (with HD15)
and then for those with RJ45 outputs.
Figure 3 – Standard matrix audio and video outputs
2.2.1 AV outputs on standard unit
The video output connectors on the basic unit are HD15 female. These are
compatible with PC’s VGA video signal (RGBHV). The Matrix is also compatible
with YPbPr HDTV signals with the use of HD15 to 3 RCA adapter cables.
The audio outputs of the matrix are balanced. So a + and a – are provided for each
side. There is also a ground connection available. If you are going to connect the
matrix output to a single-ended audio device (one with RCA or phono
connectors); then use the + of the left, + of the right, and ground. On the other
hand, if you will be connecting the output to professional audio gear it is best to
use the differential + and – (balanced) outputs of each side that offer immunity to
noise.

8x8 and 16x16 VGA / HDTV Matrix Switch with Audio, RS232 & IP Control
Figure 4 – Typical balanced audio output connector
The balanced audio outputs are provided on detachable screw-terminals. Mating
connectors for all outputs are also provided.
Technical Note about Professional Audio Output
Matrices with Pro Audio option can individually adjust the audio levels
at each input. Additionally they can set all the outputs to “pro line-level”
of +4bBu. This is a global setting which boosts all the outputs to a high
line level.
2.2.2 AV outputs on units with RJ45
Currently there are three types of RJ45 output configurations possible. Please
contact Black Box for availability and delivery information. The model number
designates the outputs either as Video on RJ45 with power, Video on RJ45 with
Audio, and Video on RJ45 with RS-232 Serial.
Figure 5 – Matrix Switch with UTP outputs
2.2.2.1 RJ45 output with Video and Power (JP)
Matrices with the Video on RJ45 with power output feature are
compatible with Black Box AC504 and AC602 series of receivers. The
Matrix can also send power to the remote receivers via the Cat5 cable
so that no external power supply would be needed there.
2.2.2.2 RJ45 output with Video and Audio (JA)
The Video on RJ45 with Audio units are compatible with Black Box
AC155 series of receivers. The audio is sent as balanced signal and is
immune to noise pickup or ground noise.
9
Model AC1120A, AC1121A, AC1122A, AC1123A
Note about Screw-Terminal Audio Outputs on units with RJ45
If the matrix has the audio switching feature, then the balanced audio
outputs are always active even if the RJ45 outputs have audio. It is
important to note that the channel number for the audio output is the
same. So RJ45 output #1 has the same audio as screw-terminal audio
output #1.
2.2.2.3 RJ45 output with Video and RS232 Serial (JR)
The Video on RJ45 with RS-232 Serial units are compatible with the Black Box
series of receivers for unidirectional (send only) and bidirectional RS-232
communications.
Technical Note about Video + RS232 Outputs
The matrices with Video on RJ45 with RS-232 Serial output
option are capable of sending and receiving RS232 data independently
at each of the RJ45 outputs with the video on the same Cat5 cable.
The output channel number and baud rate are dynamically set by the
user (via serial or IP control port). The matrix then sends user’s
command at the specified baud rate to the designated output and
buffers any response from the selected end-point for the user to read
back. This is described in further detail later in this manual.
2.3 Power input connection
The matrix has a built-in universal power supply. The AC input connector on the
rear of the matrix is an IEC320/C6 and is always shipped with a North American
power cord (shown below). Users in countries with a different plug type should
purchase a compatible power cord or user an approved adapter. The Matrix
supports both 110 V, 60 Hz and 220 V, 50 Hz power systems. There is a power on
indicator light on the front panel
Figure 6 – End of IEC320 / C6 power cord

8x8 and 16x16 VGA / HDTV Matrix Switch with Audio, RS232 & IP Control
2.4 Control Inputs
The matrix can be controlled from either RS-232 or through IP.
2.4.1 Basic Unit with RS-232 Control (no IP)
The AC1120A and AC1122A (without IP feature) actually have 2 separate and
independent RS-232 control ports.
The main RS-232 port is on a screw terminal and the auxiliary port is on an RJ45.
Caution on RJ45 Control Input
Since the matrices with the IP control and those without both have an
RJ45 connector next to the RS-232 screw terminal, it is easy to
confuse their function. The function of the connector should be labeled
above it. A sure way to tell if the RJ45 control input is LAN or Serial is
by the existence of little LED indicators to the sides of the connector. If
the connector has these lights, then it is a LAN connection, otherwise it
is an RS-232 serial connection.
Figure 7 – IP input versus Auxiliary RS-232
2.4.1.1 Primary RS-232 Control Port
This is a 3-terminal captive screw input. A detachable mating connector is
provided. The function of each pin is designated on the panel above the connector.
Below is a diagram for connection this port to a PC’s DB9 serial port.
Figure 8 – Primary RS-232 to PC cable
2.4.1.2 Auxiliary RS-232 Control Port
The matrix switches without IP control have a secondary serial port that can work
independently of the primary port. The user can control the matrix from either or
both ports.
The auxiliary RS-232 is on an RJ45. Make sure to not connect this to any LAN
devices. The pinout for the auxiliary RS-232 follows the basic EIA-561 for TX
RX and Ground. Optional current limited 12v DC may also be provided (max
rated output current of 50ma) that can be used to power external keypads or
11
Model AC1120A, AC1121A, AC1122A, AC1123A
control devices. Please contact Black Box if you need to draw power from this
connector.
Caution High-Voltage
Never open the unit’s cover. Lethal voltages exists inside the unit
Opening the unit also voids the warranty on the unit.
The pinout for the RJ45 connector is
shown in Figure 9.
Figure 9 – Aux RS-232 port pinout
2.4.2 Units with IP control
Models AC1121A and AC1123A are equipped with 10/100 base-T Ethernet
connection and can be controlled via IP. They also have the primary RS-232 serial
control port on the screw terminal input. The command set for controlling the
matrix via the IP port is exactly the same as the RS-232 port. The basic method of
control is via Telnet. Please see section 3.2.12 IP Control Basics for details.
3.0 Operation
The Matrices can be operated using the front panel buttons, by serial commands
via RS232, or through the IP port.
3.1 Front-Panel Buttons and Indicators
An image of the front panel for the 8x8 matrix is shown below. The 16x16 units
have more INPUT and OUTPUT buttons than shown in this picture.

All of the front panel switches have built-in LEDs that help in the operation. The
functions of front panel are carefully designed for intuitiveness. With just a little
practice, one can learn to quickly monitor and control the matrix.
3.1.1 Viewing Audio and Video Routings or “Ties”
There are three different ways to view a tie: Video & Audio, Video only, or Audio
only. The point of view can also be either from input side (where the selected
input is routed to), or from the output side (see which input is feeding the selected
output). You can also use the and buttons to quickly go through and check
status of all channels. Furthermore, during viewing of ties you can make new ties.
3.1.1.1 Viewing ties by Video and Audio
Press and release both VID and AUD buttons so that the LEDs of the VID and
AUD buttons are lit, which indicates that you are going to view both together.
At this point you have to decide if you want to view from the point of view of the
input or the output side.
… To View from input side
Press and release any Input button, the backlit LED of that button will light, and
all the backlit LEDs for the outputs whose video and audio are both currently tied
to this input will also light up solid.
Note
If there is audio breakaway, the output LED will not be lit. An example may be that
output #2 video is tied to input #7 while output #2 audio is tied to input 12. In this
case if you start the viewing from input #7, output #2 will not be lit even though input
7 video is routed to it. To see video ties independently from audio ties, only the Video
or the Audio LED on the front panel should be lit, not both.
You can now use the and buttons to quickly go through all inputs.
You can also make new ties by hitting output buttons. New ties will not take effect
unless ENTER is hit (see next section).
When you are done viewing ties, to exit you can hit ENTER. If you don’t hit any
buttons, then after 8 sec the view function times out and all the input and output
LEDs will go out.

… To View from output side
Press and release any output button, the backlit LED of that button will light, and
if that output’s video and audio are tied to one particular input, that input LED
will also light.
Note: If there is audio breakaway, the input LED will not be lit
You can now use the and buttons to quickly go through all outputs.
You can also make new ties by hitting another input button. New ties will not take
effect unless ENTER is hit (see next section).
When you are done viewing ties, to exit you can hit ENTER. If you don’t hit any
buttons, then after 8 sec the view function times out and all the input and output
LEDs will go out.
3.1.1.2 Viewing ties by Video only

if that output’s audio is tied to any input; then that input LED will also light.
You can now use the and buttons to quickly go through all outputs.
You can also make new ties by hitting another input button. New ties will not take
effect unless ENTER is hit (see next section).
When you are done viewing ties, to exit you can hit ENTER. If you don’t hit any
buttons, then after 8 sec the view function times out and all the input and output
LEDs will go out.
3.1.2 Making Audio and Video Routings or “Ties”
This procedure is an extension of “Viewing Ties” described in above paragraphs.
3.1.2.1 Making a tie by Input
Video and Audio to follow each other
Make sure both VID and AUD LEDs are lit, indicating that your changes will be
synchronized (audio and video are together). Video and audio will be routed to the
same input channel.
Press and release any Input button, the backlit LED of that button will light, and
all the backlit LEDs for the outputs tied to it will light up solid. At this point,
pressing any output buttons will be breaking or making connections.
To disconnect a tie, press the lit output button once. To make new ties, press any
of the unlit output buttons. The output LED will be blinking to indicate a pending
change of state. If you change your mind simply press the blinking output LED
again and it will go back to its previous state.
When you are done, press ENTER to save new changes. If you wait too long (8
seconds of inactivity) your changes will be lost and all the input and output LEDs
will go out.
Video only or Audio only
Press and release the AUD and/or VID buttons so that the backlit LED of the
desired button is lit and the other one is off.
Follow the same procedure as described above

3.1.2.2 Making a tie by Output
Video and Audio to follow each other
Make sure both VID and AUD LEDs are lit, indicating that your changes will be
synchronized (i.e. audio and video are from the same input).
Press and release any Output button, the backlit LED of that button will light, and
all the backlit LEDs for the input tied to it will light up solid. At this point,
pressing any output buttons will be breaking or making connections.
To disconnect a tie, press the lit input button once. To make a new tie, press any
of the unlit input buttons. The new input LED will be blinking to indicate a
pending change of state. If you change your mind simply press the blinking input
LED again and it will go back to its previous state.
When you are done, press ENTER to execute and save the changed route. If you
wait too long (8 seconds of inactivity) your changes will be lost and all the input
and output LEDs will go out.
Video only or Audio only
Press and release the AUD and/or VID buttons so that the backlit LED of the
desired button is lit and the other one is off. Follow the same procedure as
described above.
3.1.3 Recalling Presets (routing patterns)
The number of presets accessible from front panel is the same as # of inputs
(however through the IP or Serial port, the unit can store and recall up to 16
presets even for an 8 input Model)
Press and release the Preset button. The button will light up solid. Then press and
release the input button (it will light up) and hit ENTER. You have 8 seconds to
hit ENTER or the action will be cancelled. This will recall the desired preset tie
pattern.
Note that a recalled preset replaces the current tie configuration, which will be lost
unless it has been stored as another preset.
3.1.4 Saving Presets (routing patterns)
The current tie configuration can be saved as a preset to be called up later on.
To save the current AV routing pattern, press and hold the PRESET button for 3
sec, the backlit LED will start flashing (this means that save preset function has
been activated). Press the desired input button to save the preset (the button with
light up). Then hit the ENTER button to complete the operation. Again, you have
8 seconds to complete this sequence.
3.1.5 Disconnecting all AV outputs (blank preset)
There is a hidden blank preset (think of it as Preset #0) in the system that can be
very useful in clearing all ties. A blank preset is a preset without any ties selected
in it. To Recall a blank preset, press and release the Preset button, press and hold
the ARROW UP () button, and simultaneously press the ARROW DOWN ()
16
8x8 and 16x16 VGA / HDTV Matrix Switch with Audio, RS232 & IP Control
button. This will clear all ties. From here, the user can make new ties or save the
blank tie over a preset that had ties in it which effectively erases that preset.
3.1.6 To reset system to factory defaults
Disconnect the AC power from the unit. Press and hold the ENTER button on the
front panel while plugging in AC power. Continue to hold the ENTER button until
all LEDs on the front panel flash on. System reset clears all ties, presets, schedule
settings, and unit name.
3.1.7 To set the audio output level to high (+4dBu)
This function is applicable to units with Pro Audio option only. The matrix’s
Audio outputs can be globally set for high pro-audio line levels of (+4dBu).
Setting the pro output affects all the outputs simultaneously.
Press and hold the AUD button for approximately 3 seconds until the backlit LED
starts to blink. Either the (for high output) or the (for low output) button
LED should be lit indicating a Pro-audio level (of +4dBu) or a standard-audio
level setting (of -10dBV).
Note
If you select an input channel in this mode, the Output level setting
mode will be terminated and the unit will enter input gain attenuation
setting. To go back to the audio-level changing mode again, unselect
the current input channel by pressing it once
3.1.8 To adjust audio input gain and attenuation
This function is applicable to units with Pro Audio option only. It is very useful
for ensuring no noticeable volume difference among the audio sources, and
compatibility with a mixture of consumer and pro line levels at the inputs.
Press and hold the AUD button for approximately 3 seconds until the backlit LED
starts to blink. Press and release an input button whose audio you want to adjust.
The associated input LED lights up, the matrix will temporarily route the audio
input from the selected channel to audio output #1 and monitor its level on the
front panel. Any other outputs tied to this selected input channel stay connected
during this adjustment procedure.
The installer can connect an external VU meter to output #1 or rely on the front
panel (bottom row of lights) that would act as a digital VU meter.
In this mode both rows of 16 LED’s on the front panel serve a function.
The top row not only shows the channel for which you are adjusting the audio
(solid lit), but it also shows audio volume setting blinking position. The bottom
row (output LED’s) acts as a VU meter.
17
Model AC1120A, AC1121A, AC1122A, AC1123A
Note about VU Meter Function
The front panel VU meter function is available on both the 16x16 and the
8x8 units with standard or Pro audio versions. However on the standard
version the and buttons do not change the volume level. The user
can do that at the source and use the matrix to monitor the level.
3.1.8.1 Using the Front Panel VU meter
This function is useful for ensuring no noticeable volume difference among the
audio sources for models AC1121A and AC1123A.
All units with audio option have this feature. Enter the audio adjustment mode as
described above. The bottom row of LEDs (output channel row) indicates the
sound level. The indicated gain/attenuation is based on the matrix’s internal
reference level of -10dBV (standard line-level).
On a 16x16 matrix LED position 10 corresponds to 0 VU (desired peak level).
Position 1 corresponds to -20 VU and position 16 corresponds to +6 VU.
The bottom row of 8 or 16 LEDs indicate the sound level. Position 10 (or 5 for
8x8 matrix) is used to correspond to 0 VU (desired peak level).

Figure 12 – Graph of VU dB level versus LED bar length
3.1.8.2 Adjusting the input audio Gain or attenuation
Enter the audio adjustment mode as described above.
Initially the audio gain level at the input is set to 0 db (gain of 1). Press and
release the or button to change the gain settings. Each push is about 1dB
change (see graph below). Press and hold the UP or DOWN button for more than
1 second, the gain will keep changing at the rate of 3dB per second. As you
increase or decrease the volume, besides the LED on the top row that is showing
the input channel you are adjusting, another blinking LED indicates the audio gain
setting. Again, position #10 indicates 0 db (or gain of 1). The range of
adjustment is about -24 dB to +6 dB (position 1 to position 16).
Figure 13 – Graph of Audio Gain level versus Volume setting LED position
19
Model AC1120A, AC1121A, AC1122A, AC1123A
In adjusting the volume you want to keep the sound level as read on the VU meter
at or below Position 10 (0 VU) for the loudest level at the input.
When finished, press the ENTER button to save any changes or exit the audio
adjustment mode. When you exit this mode, the last audio input that was routed to
output #1 prior to entering the setting mode will be restored!
Audio Setup mode times out if no activity is detected for 1 minute, the last input
gain settings will be saved.
3.2 Control Commands (RS-232 and IP)
The matrices can be controlled via an external control system by using RS-232.
Additionally, Models AC1121A and AC1123A can be controlled through an IP
port. Any program capable of standard serial communication in ASCII format is
capable of working with the matrices. Most PCs with Microsoft Windows
operating systems have HyperTerminal™ pre installed with this capability. There
are also many free Terminal Emulator and Telnet software programs available for
download on the internet.
Note on RS-232 port availability on your PC
Most PCs and notebooks do not have a serial port. So to program the
Matrix Switch you may need a USB to RS-232 Serial converter. These
are available from Black Box (Model IC199A-R3).
Figure 14 – USB to RS-232 Adapter
Use Figure 8 to connect the unit to the PC’s serial port. Use 9600 Baud, 8 bits, No
Parity, 1 Stop bit, No flow control.
Upon power up, the matrix will output a screen similar to the figure below
through its serial port(s).
Unit's name:

Figure 15 – Power on screen
20
8x8 and 16x16 VGA / HDTV Matrix Switch with Audio, RS232 & IP Control
Note on RS-232 commands
When the front panel is in use (for example to make new ties or recall presets,
etc), only status request commands are accepted. Any other command will be
prompted with the following response:
Front panel is in use<cr>
Fortunately, all front panel operations have a timeout function so even if a user
started to use the panel but forgot to finish the process, it will time out in a few
seconds and full serial port functionality will be restored.
3.2.1 Naming Functions
The matrix unit can be named. Its name can be up to 10 characters long.
To assign or retrieve a unit name:
Command: NU<cr>
Response:
stands for Name Unit
xxxxxxxxxx (current name up to 10 characters)
Rename unit:
No change<cr>
If you hit <cr> or wait 5 seconds (command times out) the unit will respond with:
Cancelled<cr>
Otherwise you have 5 seconds to change the name by entering up to 10 ASCII
characters followed by <cr>. If you just send a <cr> then the stored name will not
be changed. If you enter more than 10 characters, then the 1st 10 characters will
be saved as the name and the rest discarded.
3.2.2 Routing Functions
Wildcard character
Video routing commands are specified from the point of view of the output.
The wildcard character ‘*’ is acceptable for output (but not input). This
means that any place a ‘*’ is used as a valid command, it means ALL
OUTPUTS. For example, CV*,1 means to connect all outputs to input #1.
Blanking Video or Muting Audio
When a ‘0’ is used as an input channel number, it means that the intent is to
either blank (when used with a video command), mute (when used with an
audio command) or both. For example, CV*,0 means to blank all video
outputs. CA*,0 means to mute all audio outputs.
In addition, these commands can be used to monitor or query the status of system
ties. Omitting the input channel will result in a response of the current routing for
that output. In entering channel numbers leading zeros are acceptable hence you
can specify channel 7 as 07 or just 7.

if the “Y” was entered.
Cancelled<cr>
if other key was entered or command times out.
Note: Restore Factory command will clear all ties, presets, schedule settings, and
unit name. -AP units with input volume adjustment will set input volume to 0 dB
(gain of 1) on all channels. Upon completion of this command, all LEDs on the
front panel will flash on and off.
3.2.5 Rebooting the System
To perform a system reset/reboot (same effect as cycling AC power):
Command: FB<cr>
Response:
stands for Firmware Boot
Are you sure (Y,N)?<cr>
Note: You have 5 seconds to press Y, or the command is cancelled.
3.2.6 Setting Outputs to PRO Audio Line Levels
The matrix’s outputs can be set for Pro-audio line levels of (+4dBu). Setting the
pro output affects all the outputs simultaneously and has no bearing on the audio
input volume adjustment procedure.
To set audio output line-level mode:
Command: LPn<cr>
stands for Line level Pro n = 0,1 (0 consumer, 1 pro)
If the parameter n is missing, then the unit will respond with the current setting.
R esponse: LPn<cr>
3.2.7 To Adjust Audio Input Gain and Attenuation
This command is valid for units with Pro Audio (-AP). The wildcard character ‘*’
is acceptable for input audio channel. In addition, this command can be used to
monitor or query the audio input gain. Omitting the gain value will result in a
response of the current setting for that output
To set the audio gain (default value is 10 that corresponds to a gain of 0 db):
Command: AGn, g<cr>
stands for Audio Gain n = input channel (could be *), g=
value (0 to 16 where 0 is mute & 16 is +6dB see figure 14 X-axis 0 to 16)-Response:
AGn, g<cr>
Note: if you enter AGn<cr> then you will get the response as above for the n input

3.2.12.2 Scheduling Auto recall of Preset Patterns
The matrix provides up to 4 specific times throughout the day where any preset
patterns (0 to 16) can be recalled. You can set a schedule that is the same every
day (daily) or is different for weekdays and weekends. Presets 1 to 16 are those
saved by the user, and preset 0 disconnects all video and audio outputs
Notes on Scheduling Presets
When defining a schedule, to skip the current prompt without making a change,
press ENTER. Press ESC to exit the schedule setting at any time. Timer values
should be entered in the proper order meaning that Timer1 should occur prior to
Timer2, Timer2 should occur prior to Timer3, and etc. Timers will be disabled if
hour, minute, and AM/PM are set to 0. So if for example, your schedule only has
to set the pattern once in the morning, leave the data for timers 2 through 4 at
zero and only enter values for timer 1. If Timer values are not set properly (in
ascending order), an error message will be prompted

Figure 16 – RS-232 Communication Methodology
The block diagram above depicts the way a user can communicate serially with a
remote devices connected to the matrix’s outputs. Matrix units with JR output
option can send video and serial through the same RJ45 output connector. A
compatible receiver must be used at the remote end (such as UR-232 for transmit
only).
Referring to the above diagram, two control ports are shown on the left. The user
communicates with the matrix’s internal processor through either of these ports.
As seen on the right side of the block-diagram, the matrix must first establish
UART (RS-232 engine) connection to one of the matrix’s output ports. There is a
specific command for doing this which makes the connection and also clears both
the input and output buffers of the internal UART.
Once the UART is pointed to the desired output, then any data received from the
remote device (1~16), is stored in the “IN BUFFER”. There is a command to read
this buffer. Upon receiving this command the matrix will send the entire contents
of the input buffer to the user and erase the buffer.
To send commands out to the remote device (1~16), the user can issue a transmit
command followed by a string of characters (ASCII or Hex), these characters are
stored in the UART’s output buffer. The user’s string must end with a special
“Terminal Character” followed by a Carriage Return. At that point the UART will
empty the output buffer to the selected remote device at the specified baud rate
(Terminal Character and subsequent CR will not be sent).
27
Model AC1120A, AC1121A, AC1122A, AC1123A
3.2.13.2 Commands for Serial Communication with each Output
All serial communication commands start with the letter X
1. Command: XC,n
<cr>
Stands for X Connect
Connects the UART an output (n) if n not specified, then it reports which output
the UART is pointed to.
Response:
XC, n <cr> This indicates that the command completed successfully
2. Command: XT <cr>
Stands for X Transmit
After this the matrix will wait for a max of 5 seconds to get the string of bytes
that are to be sent out. The number of bytes cannot exceed 64. If you have more
than 64 characters to send then you have to use multiple commands.
The unit stores all characters in a buffer and then sends all characters at the
specified baud rate to the desired output channel.
The unit does not care what data or characters are sent and they can range from
hex 0 to hex FF. What designates the end of the string are two specific bytes:
17h 0Dh -- 17 hex (^W) followed by 0D hex (Carriage Return)
17hex is considered to be a special Terminal Character. When the unit receives
17h then it looks for a CR to follow it. If CR does not follow the 17h, then the
17h is assumed to be part of the user’s string.
On the surface there appears to be a restriction in that the user’s string cannot
contain 17h 0Dh back-to-back. However, the matrix has a special provision for
the rare case when the user’s data is to contain 17h 0Dh back-to-back. Inserting
17h 17h 0Dh results in the transmission of 17h 0Dh and is not interpreted as a
termination of the stream.
After the 17h 0Dh the system initiates transmition of the sring received to the
target at the specified baud rate. The user must wait for this process to finish
prior to issuing another command.
Response: OK <cr>
3. Command:
XR <cr> Stands for X Receive
The matrix stores the last 64 bytes received from the target in a receive FIFO,
then upon receipt of this command it sends whatever it has (as binary) out to the
user. Nothing if the buffer is empty.
Response: Any
28
characters in the receive FIFO buffer.
8x8 and 16x16 VGA / HDTV Matrix Switch with Audio, RS232 & IP Control
4. Command: XB,n <cr>
Stands for X Baud
If n is not specified it reports the current baud rate (1-8).
n = 1, 2, 3, 4, 5, 6, 7, 8
Baud = 1200, 2400, 4800, 9600, 19.2k, 38.4k, 57.6k, 115.2k respectively

Figure 17 – Control Block Diagram
As shown in the figure above, the matrix can be controlled via RS232 Serial port
or through an IP (Ethernet) port if equipped. If the unit is missing the IP port, then
in its place, there is an auxiliary 2nd serial control port (see section 2.4.1).
The IP port of the matrix can be accessed via Telnet (interactive TCP connection).
Two ports are available, one for controlling the matrix and the other to configure
the IP parameters.
Though not recommended, using port 23 you can change the Ethernet interface’s
IP parameters such as IP address, gateway, port number, etc. The IP settings can
also be accessed through the unit’s RS232 serial port (recommended).
Port 1001 by default is used to control the matrix (this port number can be
changed as part of the IP Settings). The commands used to control the matrix are
the same as those through the RS-232 Serial port.

3.2.12.2 IP Configuration through port 23
If you were unable to enter the IP setting mode through the serial command, a
Telnet TCP programming method should be used to turn on RS-232 serial mode
programming, or even to configure the network settings directly through port 23.
To open a Telnet section, a command prompt (Run: CMD) or a HyperTerminal
window can be used:
For example, to run a HyperTerminal window, set it up for TCP/IP connection on
PORT 23 along with the Matrix’s default IP address as the host address.
Telnet commands and replies have the following format:
STX
∞
Command/reply
CR
STX character (ASCII code 2 or CTRL-B from the keyboard)
The unit will respond with <CTRL-B> A for most valid commands.
1. To use the IP configuration Telnet commands, you must first log in using the
(L) command.
Command: <CTRL-B>
L <CR>
stands for Log in
2. To enable a serial IP setting (serial programming) mode, type the following
commands:
Command: <CTRL-B>
SSE2 <CR> Stands for Set Serial Enable
Command: <CTRL-B>
SEC6 <CR> Stands for Serial Enable Char
Command: <CTRL-B>
O <CR> stands for log out
Reboot the system by cycling power. Now you should be able to configure IP
parameters through the IP port.
Alternatively, instead of rebooting the system you could use <CTRL-B> <E>
<CR> to reboot the IP port, this may cause a momentary loss of Telnet
connection.
3. To get the current IP address:
Command: <CTRL-B> GIP <CR>
Response: <CTRL-B> A 192.168.123.180

Note on IP Settings through port 23
If you are unable to access the unit’s
port 23 from your PC using the
matrix’s default or last known IP
address, it could be that the IP
address of the matrix is not
compatible on your LAN. One way
around this is to connect your PC
directly to the Matrix’s IP port using a
cross over cable, or use a switch or
router not connected to anything else
but your PC and the Matrix, and then
configure your PC for a static IP
compatible with the current address
of the matrix. If the matrix has the
factory default of 192.168.123.180, a
PC address of 192.168.123.nnn may
be entered where nnn is any number
except 180.
Note on Accessing the Matrix via the Internet
It is best to contact your IT or network administrator for assistance. As
mentioned earlier you can control the matrix through its IP via port
1001 (default). Most likely, the unit will be on a local network
connected to an Ethernet Switch or Router with a WAN connection. To
access the matrix from outside your local network, you should
configure the Ethernet Switch or Router to treat the IP and port
assigned to the matrix as a virtual server this is a setting of your switch
or router. Then you can access the matrix from anywhere on the
internet via your WAN address and assigned port. It is advised to set
the matrix’s Gateway address the same as your Ethernet switch or
router’s Gateway IP address. In case of trouble, please contact your IP
administrator for assistance.
