Safety Precautions
Safety Precautions
For reliable operation of the equipment and personnel safety, follow the guidelines
below for installation, use, and maintenance of the device.
1. The system must be grounded properly. Do not use two-blade plugs and ensure the
alternating power supply ranges from 100 to 240 VAC and 50 to 60 Hz.
2. Do not put the control panel in an environment that is not within the its temperature
tolerance.
3. Because the switch’s power generates heat when running, be sure the working
environment is properly ventilated to avoid damage caused by equipment
overheating.
4. Turn off the general power switch in humid weather or when the control panel will
be left unused for long time.
5. Before operating, be sure that the alternating current wire is pulled out of the power
supply.
6. NEVER open the casing of the equipment, DO NOT repair it on your own. This might
be harmful to persons or the equipment.
7. DO NOT splash any liquids on or around the equipment.

Chapter 3: System Connection
3. System Connection
3.1 Usage Precautions
1. Install the system in a clean environment that has a proper temperature and
humidity.
2. Make sure that all of the power switches, plugs, sockets and power cords are
insulated and safe.
3. Connect all devices before powering on.
Figure 3-1. Connections.
3.2 Connection Procedure
Step 1: Connect an HDMI source (such as a Blu-ray™DVD) to the HDMI IN port of
AVS-HDB-TX with HDMI cable.
Step 2: Connect the HDBT OUT port of AVS-HDB-TX to the HDBT IN port of the
AVS-HDB-RX through a CAT5e/CAT6 cable.
Step 3: Connect an HDMI display (such as HDTV) to the HDMI OUT port of the
AVS-HDB-RX with HDMI cable.
Step 4: Both AVS-HDB-TX and AVS-HDB-RX have IR IN and OUT. When one end is
used as an IR receiver, the other end will be used as an IR transmitter.
For example: When “IR IN” of AVS-HDB-TX connects to an IR receiver, the IR transmit-
ter must be connected to “IR OUT” of the AVS-HDB-RX.

Page 16
877-877-2269 | blackbox.com
Chapter 3: System Connection
Step 5: Connect the RS-232 port of the devices to control to the receiver or the
transmitter.
Step 6: Connect the 24-VDC power adapter to either the transmitter or receiver.
NOTE: The power supply is not required on both ends. Only one of the units,
transmitter or receiver, requires power.
3.3 Application
Use the AVS-HDB-TX and AVS-HDB-RX for computer monitoring, conference rooms,
large-screen displays, television, education applications and more.
3.4 Twisted-Pair Cable Connection
The twisted pair used with the extender MUST be a straight-through cable. The connec-
tors can be T568A or T568B, but both sides must be the same.
Figure 3-2. Cable pinout diagram.
NOTE: Cable connectors must be metal, and the shielded layer must be connected to
the connector's metal shell to ground the cable.
3.5 Extending Transmission Distance
The AVS-HDB-TX, AVS-HDB-RX, and AVX-HDB-4TX extenders, and AVS800 and
AVS1600 switchers work with the Multi-Format Video Scaler with Extension - 5-Port
(AVSC-5DA1-HDB) to extend the transmission distance of an HDMI/IR/RS-232 signal.
