Overview

The ATEN VP3520 is a multi-in-one presentation matrix switch that integrates a video matrix switch, 4K scaler, HDBaseT extender, and audio DSP functions into one compact device that easily mounts under a table or in a rack. The VP3520 seamless presentation matrix switch with control features the true 4K video resolutions of 4096 x 2160 / 3840 x 2160 @ 60 Hz (4:4:4) and HDR technology, guaranteeing crystal-clear images across two displays. The VP3520 supporting 4K @ 60 Hz, HDMI, and HDCP 2.2 features Seamless Switch™ that employs an FPGA matrix architecture that ensures continuous video streams, real-time control, and stable signal transmissions. With a built-in high-performance 4K scaler, the VP3520 easily converts various input resolutions into various output display resolutions, giving viewers the best video and picture quality across the two displays.

With flexible audio de-embedding, the VP3520 is designed with the audio routing flexibility to meet different application requirements. In a simple setup, HDMI audio can be connected and switched directly to display audio. For a more complex setup, the HDMI audio can be de-embedded to Audio Line Out in order connect to your preferred in-room audio equipment. Equipped with 5 digital inputs to one HDBaseT and one HDMI True 4K separate outputs, the VP3520 enables to control 2 displays at the same time and is designed to boost the efficiency and impact of professional presentations. The VP3520 provides users the flexibility of using both active and passive speakers with its stereo line out port, coaxial port, and 2 x 10 W power amplifiers.

As for the control functions, the VP3520 offers users the multiple control options such as the front-panel pushbuttons, IR remote control, RS-232 commands, and web-based GUI. Moreover, the VP3520 enables to control of AV devices such as TV displays, projectors, and monitors. It is ideal for all meeting space and education environments, including huddle rooms, classrooms, training rooms, or any other presentation setting such as in exhibition galleries or hotels.

IR Serial Connection

The IR ports on the VP3520 provide IR remote control of the connected HDMI display.

IR Ports IR S G Connects to HDMI display

Overview

This chapter provides information on operating the VP3520 using the front panel and IR remote control.

Note: The instructions use pushbutton to refer to the front panel and button to refer to the IR remote control.

Operation Considerations

• To use the IR remote control, make sure to insert the IR receiver (supplied in the package) to the VP3520.
• To ensure smooth operation using the IR remote control, use the IR remote control within the effective range (6 m) and keep a clear line-of-sight between the remote control and the IR receiver connected to the VP3520.

Switching Sources

To switch the video source on a display:

1. Press a display selection pushbutton (VP3520 front panel) / button (IR remote control) to select a display. The pushbutton (VP3520 front panel) for the selected display lights orange.
2. Press a source selection pushbutton (VP3520 front panel) / button (IR remote control) to assign the source. The pushbutton (VP3520 front panel) for the selected source lights orange.

Note: appears on the top left corner of the OSD for 5

seconds when the source is switched. This is the resolution from the original source without scaling.

Display Mode

The VP3520 supports the following display modes:

• Matrix mode (B): When enabled, the AV sources can be configured separately, capable of showing different outputs.
• Mirror mode ( ) When enabled, display B uses the AV source assigned for display A and shows identical content.

Audio Settings

• To adjust the volume for all audio outputs on the VP3520, use the volume knob on the front panel or the volume up or volume down buttons on the IR remote control.
• To adjust the volume of a microphone or an independent audio source on the VP3520, use the mic knob on the front panel.
• To mute all audio outputs (displays and speaker), press the volume knob on the front panel or press the mute button on the IR remote control.

Enabling / Disabling the Panel Lock

To prevent accidental tampering of system settings via the front panel, you can lock the panel by pressing the function selection pushbutton 4 (Fn4) for set up an idle time for an auto lock via the web console (General > Basic > Panel Auto Lock). Refer to the table below for how to enable / disable the panel lock and the corresponding LED indication.

Task	Lock LED (Mode Pushbutton)

Overview

The VP3520 can be configured and controlled via RS-232 or Telnet commands when connected to a host computer or other device, such as a control system. This chapter provides information on how to connect to the VP3520 via RS-232 / Telnet and command syntax.

Connecting to the VP3520 via Telnet

To establish a Telnet session with the VP3520, do the following:

1. Connect a host computer or control system to a shared network with the VP3520.
2. Open a command-line interpreter program from your computer.
3. In the command-line interpreter, type the VP3520's IP address in the following way:

telnet [IP address]:23

1. Press Enter. The login screen appears.
2. At the login prompt, type the login username and password for the VP3520.
3. When a session is established with the VP3520, you can control and configure the VP3520 via RS-232 commands. For more information on commands, see:

◆ Command Syntax, page 59

◆ Command List, page 60

Note: If a user logs in using a username that is already in session, the newest login takes effect and the previous session will be replaced.

Connecting to the VP3520 via RS-232

1. Connect a host computer or control system to the RS-232 serial port on the VP3520 unit.

2. Download and install controller software that supports RS-232 serial control and the operation system of your controller PC.

3. Execute the software and configure the connection settings to the following:

♦ Serial line to connect to: COM1
♦ Speed (baud): 19200
◆ Data bits: 8
- Stop bits: 1
Parity: None
◆ Flow control: None

1. When a session is established with the VP3520, you can control and configure the VP3520 via RS-232 commands. For more information on commands, see:

◆ Command Syntax, page 59
◆ Command List, page 60

Command Syntax

◆ The general form of a command is:

command parameter<argument> {one|two|three} 

Notation Description
command	The name of the command is shown in bold.
parameter	Indicates the name of the parameter.
	Indicates the name of the value or the information that the user must provide. Only type the information in the angle brackets, not the brackets themselves.
[ ]	Indicates optional items. Only type the information in the brackets, not the brackets themselves.
{ }	Indicates a set of choices from which the user must choose one.
|	Indicates two or more mutually exclusive choices in a command line. Only type one of the choices in the command line, not the symbol.

If you have two or more parameters, the order of these parameters among themselves does not affect the result of the operation. For example, both of the following commands execute the same task:

command name + parameter 1 + parameter 2 

command name + parameter 2 + parameter 1 

Command List

Use the following commands to control and configure the VP3520 via Telnet or RS-232. For details on establishing a Telnet or RS-232 session to the VP3520, see Connecting to the VP3520 via Telnet, page 57 and Connecting to the VP3520 via RS-232, page 58.

Rack Mounting

Before working on the rack, make sure that the stabilizers are secured to the rack, extended to the floor, and that the full weight of the rack rests on the floor. Install front and side stabilizers on a single rack or front stabilizers for joined multiple racks before working on the rack.
- Always load the rack from the bottom up, and load the heaviest item in the rack first.
- Make sure that the rack is level and stable before extending a device from the rack.
- Use caution when pressing the device rail release latches and sliding a device into or out of a rack; the slide rails can pinch your fingers.
- Do not overload the AC supply branch circuit that provides power to the rack. The total rack load should not exceed 80 percent of the branch circuit rating.
- Make sure that all equipment used on the rack – including power strips and other electrical connectors – is properly grounded.
- Ensure that proper airflow is provided to devices in the rack.
- Ensure that the operating ambient temperature of the rack environment does not exceed the maximum ambient temperature specified for the equipment by the manufacturer.
- Do not step on or stand on any device when servicing other devices in a rack.
