Frequently Asked Questions - AVS-HDB-WPTX Black Box

How do I switch between HDMI and VGA input sources?

Press the SOURCE/AUTO button on the front panel to cycle between HDMI and VGA. The selected source indicator lights green. You can also use RS-232 commands 50701% (HDMI) and 50704% (VGA).

What is auto-switching mode and how do I enable it?

Auto-switching mode automatically selects the last connected source. Press and hold the SOURCE/AUTO button for 3 seconds until the backlight turns on; the unit enters auto-switching mode. Alternatively, send RS-232 command 50770%.

Can I power the AVS-HDB-WPTX via PoC?

Yes. The AVS-HDB-WPTX supports unidirectional PoC: it can receive power from a far-end PoC receiver (e.g., AVS-HDB-RX) via the HDBaseT connection. It cannot power far-end devices.

What video resolutions does the extender support?

VGA resolutions up to 1920x1200 (WUXGA). HDMI resolutions up to 4K x 2K and 1080p 3D. The built-in scaler adjusts output to match the display's native resolution.

How do I update the firmware?

Save the firmware file (named MERGE.bin) to a USB flash drive, insert it into the USB port on the front panel, then send RS-232 command 50698% to initiate the update.

What is HDBaseT and how far can I transmit signals?

HDBaseT transmits HDMI/VGA, audio, RS-232, and power over a single CAT5e/6 cable. Maximum distance is 60 m (197 ft) for 1080p and 40 m (131 ft) for 4K with PoC enabled.

How do I control the extender via RS-232?

Connect a control device (PC) to the RS-232 port (front or rear). Use baud rate 9600, data bits 8, stop bit 1, parity none. Send commands like 50701% for HDMI switching, 50626% for resolution change, or 50617% for factory reset.

What should I do if there is no video output?

Check cable connections and try high-quality cables. Ensure the source is powered and selected. Verify the HDCP status (LED on front panel). If using PoC, ensure the receiver is powered. For persistent issues, contact Black Box Tech Support.

What is included in the package?

The package includes the AVS-HDB-WPTX transmitter, faceplate, screws (4 for unit, 4 for faceplate), three pluggable terminal blocks (2-pin, 3-pin, 4-pin), and a printed user manual.

Can I use this extender in a residential environment?

This device is FCC Class A rated for commercial use. In a residential area, it may cause radio interference; the user must take corrective measures at their own expense if interference occurs.

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.

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.

    A -->|DC 12V OUT| C["Device 2"]

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.

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.

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.

Accessing through Serial

1. Using the client, select "serial" and enter "115200" for the speed (baud rate).

Figure 4-1. PuTTY configuration screen using serial.

1. No username or password is required. Just press enter.

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.
