Chapter 2: Overview
2. Overview
2.1 Introduction
HDMI Matrix Switches from Black Box support sharp, highly defined video in HD
resolutions of up to 1080p—with a bandwidth of 6.75 Gbps.
Any input can be routed to any output, or the same input can be routed to all
outputs or any combination, eliminating the need to manually move various cables
to display HDMI video from different sources on different screens. An input source
LED tells you at a glance each output you’ve selected.
The switch sets up in seconds and is easy to use. Control using front-panel
buttons, the included IR remote controller, or an RS-232 connection linked to a
Crestron®, AMX®, Control4®system, or any third-party computerized software/
hardware control system. The switch even comes with an RS-232 serial cable for
quick setup.
The switch also has an IR signal extension port (and includes an IR extender
receiver). Once plugged in, the receiver enables you to use the IR remote
controller to switch ports on the unit from another room—up to 984 feet
(300 m) away.
Four models are available:
• AVSW-HDMI4X4: (4) HDMI inputs, (4) HDMI outputs
• AVSW-HDMI2X4: (2) HDMI inputs, (4) HDMI outputs
• AVSW-HDMI4X2: (4) HDMI inputs, (2) HDMI outputs
• AVSW-HDMI2X2: (2) HDMI inputs, (2) HDMI outputs
2.2 Features
• HDMI 1.3 and HDCP compliant.
• Works with all HDMI sources and displays—plus it’s 3D capable.
• Signal boosters on ports amplify HDMI signals up to 60 feet (18.2 m).
• Supports the latest HDMI audio formats, including Dolby®TrueHD and DTS-HD.
• Carries the high-speed digital video signaling of TMDS formats for the delivery
of 12-bit Deep Color.
• Ideal for corporate theaters, conference rooms, classroom and training facilities,
and video broadcasting applications.

4.2 RS-232 Serial Control Port
You can control the HDMI Matrix Switches via the RS-232 serial control port for
interfacing to a PC. The serial communication parameters are: 9600 baud, 8 bits,
no parity, and one stop bit. This is often referred to as 9600 8N1.
When the switch recognizes a complete command, it will perform the requested
action—no deliminater charcter is required. The unit does not send out a message
when a value is changed from the front panel or via IR control. If you need to
control the unit via the front panel in addition to the RS-232 control, you should
regularly poll the unit status to ensure that the control system accurately reflects
the current settings or similar third-party control system.

Chapter 5: RS-232 Serial Commands
5. RS-232 Serial Commands
To switch inputs to outputs:
SBI02O0Y (where X is the output number [1-4] and Y is the input number [1-4]).
Unit will respond with:
SBUD0XOY (where X is the output number [1-4] and Y is the input number [1-4]).
Example: Send input 2 to output 3:
SBI02O03: Send
SBUD02O3: Recvd
5.1 Standby Mode
NOTES: Turning the unit‘s System Power Off over RS-232 will turn off the LED
display, leaving only the Power Switch LED on. The video and audio
outputs will also mute.
While the unit is turned off by RS-232, it will continue to accept and act
upon switching commands. For example, if the unit is in the off mode
(via RS-232) and you send a command to switch an input to an output,
that route will complete and the video and audio will now appear
on that channel only.
The front panel LED for that particular output will also show the input
selected (for that single output channel only). The remaining LEDs will
stay off and video and audio outputs muted.
The unit will still return status and change messages in response to
commands sent while in Power Off state.
A hard reset command (SBALLRST) will return the unit to normal
operation and also unlock the front panel.
5.2 Power Off Mode
SBSYSMOF: Put system into Standby (soft power off).
SBSYSMON: Bring the unit out of Standby (soft power on).
Unit will respond with:
SBALOFAX: Unit is in standby.
SBALONAK: Unit is no longer in standby.
Example: Put unit in standby (soft power).

Unit will respond with:
SBSYSLOK: Front panel has been locked.
SBYSULK: Front panel has been unlocked.
Example: Lock front panel buttons
SBSYSMLK: Send

7.1 Safeguards
To reduce the risk of electric shock, do not expose this product to rain or
moisture. If the wall plug does not fit into your local power socket, hire an
electrician to replace your obsolete socket.
Do not modify the wall plug. Doing so will void the warranty and safety features.
Install this equipment near the socket outlet. The device should be easily accessible
in case you need to disconnect it.
7.2 Precautions
FCC regulations state that any unauthorized changes or modifications to this
equipment not expressly approved by the manufacturer could void the user’s
authority to operate this equipment.
Operate this product using only the included external power supply. Use of other
power supplies could impair performance, damage the product, or cause fires.
If an electrostatic discharge occurs, this device may automatically turn off. If this
happens, unplug the device, and plug it back in.
Protect and route power cords so they will not be stepped on or pinched by any-
thing placed on or against them. Be especially careful of plug-ins or cord exit
points from this product.
Avoid excessive humidity, sudden temperature changes, or temperature extremes.
Keep this product away from wet locations such as bathtubs, sinks, laundries, wet
basements, and swimming pools.
Use only accessories recommended by Black Box to avoid fire, shock, or other
hazards.
Unplug the product before cleaning. Use a damp cloth for cleaning. Do not use-
cleaning fluid or aerosols, which could enter the unit and cause damage, fire, or
electrical shock. Some substances may also mar the finish of the product.
Never open or remove unit panels or make any adjustments not described in this
manual. Attempting to do so could expose you to dangerous electrical shock or
other hazards. It may also cause damage to your matrix switch. Opening the
product will void the warranty.
Do not attempt to service the unit. Instead disconnect it and contact Black Box
Technical Support at 724-746-5500 or [e-mail].
