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.

2. Overview
2.1 Introduction
The Video Extender —4K HDMI, VGA, RS-232, Wallplate Transmitter with Audio (AVS-
HDB-WPTX) is a Decora style transmitter that installs in a double-gang wall box to pro-
vide a convenient interface for HDMI/VGA input sources. It has (1) HDMI IN, (1) VGA IN
and (1) HDBaseT OUT with PoC connector. It supports VGA as a full HD scale. HDMI 1.4
with 4k and 3D input signals support auto-switching and manual-switching. The
HDBaseT output supports 60-m UHD video transmission with PoC, and enables bi-direc-
tional RS-232 communication between the AVS-HDB-WPTX and the remote device.
Using PoC, AVS-HDB-WPTX can be powered via a far-end PoC receiver.

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 the power switches, plugs, sockets, and power cords are insulated
and safe.
3. Connect all devices before powering on.
Blu-ray™
AVS-HDB-RX
Figure 3-1. Connections.
3.2 Connection Procedure
Step 1: Connect an HDMI source device (e.g. Blu-ray DVD) to the HDMI input port of
the AVS-HDB-WPTX with HDMI cable. Connect a VGA source device (e.g. PC)
to the VGA input port of the AVS-HDB-WPTX with VGA cable.
Step 2: Connect a AVS-HDB-RX to the HDBaseT port on the rear panel with twisted
pair.
Step 3: Connect a HDMI display to the HDMI OUT port of AVS-HDB-RX.

Page 15
877-877-2269 | blackbox.com
Chapter 3: System Connection
Step 4: Connect a control terminal to the RS-232 port on the front panel of the
AVS-HDB-RX.
Step 5: Connect a control device (e.g. PC) to the RS-232 port of the AVS-HDB-WPTX or
the AVS-HDB-RX (bi-directional RS-232 control, either is available).
Step 6: Connect the 24-VDC power adapter to the power port of the AVS-HDB-RX.
AVS-HDB-WPTX can get power from AVS-HDB-RX via PoC.
NOTE: AVS-HDB-WPTX supports unidirectional PoC, i.e, AVS-HDB-WPTX can get power
from far-end PoC devices with PoC function, but it can’t power far-end PoC
devices when the power supply is connected to the AVS-HDB-WPTX.
3.3 Powering On the Unit
AVS-HDB-WPTX has a 12-V power output port on the rear panel. Connect the 12-VDC
power output port of the AVS-HDB-WPTX to the power port of the AVS-CTRL8 (refer
to the following figure). AVS-HDB-WPTX can power the AVS-CTRL8.
AVS-CTRL8
Figure 3-2. Power connections.
3.4 PoC Solution
AVS-HDB-WPTX has a HDBaseT OUTPUT port on the rear panel, which can extend
HDMI/ VGA signals up to 60 m. It also supports PoC, which allows several terminals to
share the same power supply and eliminates the need for an extra power supply at the
remote nodes.

Page 16 877-877-2269 | blackbox.com
Chapter 3: System Connection
Connect a 24-VDC power adapter to the power port of AVS-HDB-RX. AVS-HDB-WPTX
can be powered synchronously via PoC.
Figure 3-3. PoC connections.
3.5 Application
Use the AVS-HDB-WPTX for computer monitoring, conference rooms, large-screen
displays, television, education applications and more.

Chapter 4: Operation
4. Operation
4.1 Front-Panel Buttons
AVS-HDB-WPTX has a channel switching button on the front panel, through which
users can switch input source signals.
It supports both manual switching and auto switching. (The default setting is Auto
switching.) Press and hold the switching button for 3 seconds or send command
“50770% “ and “50771%” to switch between the two modes.
Switching modes:
• Auto switching mode: In this mode, the indicator will light green, and
AVS-HDB-WPTX will recognize the last connected source device as the input source
automatically.
• Disconnect the present source device, and it will deliver the other source signal (if
there is an input signal on the other source).
• Manual switching mode: In this mode, the indicator will remain off. Press the
switching button to select the input source, it will switch circularly between HDMI and
VGA. Or switch it by sending RS-232 commands. The indicator of the selected input
source will light green.
4.2 RS-232 Control
RS-232 can be transmitted bi-directionally between AVS-HDB-WPTX and AVS-HDB-RX,
so it can control a third-party RS-232 device locally or control an AVS-HDB-WPTX from
remotely. To control a third-party RS-232 device, set the baud rate of this device to
2400, 4800, 9600, 19200, 38400, 57600, or 115200.

Page 18 877-877-2269 | blackbox.com
Chapter 4: Operation
Accessing through Serial
1. Using the client, select “serial” and enter “9600” for the speed (baud rate).
2. No username or password is required.
Set the COM number, baud rate, data bit, stop bit, and parity bit correctly so you can
send commands in the Command Sending Area of the screen.
NOTE: To control the AVS-HDB-WPTX via an RS-232 port, configure the communication
protocol parameters as: Baud rate: 9600; Data bit: 8; Stop bit: 1; Parity bit: none.
