Frequently Asked Questions - R4N86NNU ORION

How do I set up a video wall with multiple R4N86NNU monitors?

To configure a video wall, use the On-Screen Display (OSD) menu. Navigate to the 'Video Wall' section and enable it. Set the 'Position' according to your monitor layout (1 to 81) and adjust 'H Ratio' and 'V Ratio' for horizontal and vertical counts. Use the joint brackets supplied to align monitors. For detailed commands, refer to the R4N Commander protocol in the manual.

How should I clean the monitor safely?

Before cleaning, unplug the monitor from the power outlet. Use a soft, dry cloth to wipe the screen. Do not use liquid cleaners, chemical liquids, or abrasive materials, as they may cause fading or damage. Avoid pressing hard on the LCD panel.

What input sources are available on the R4N86NNU?

The monitor supports VGA, DVI, three HDMI inputs, and DisplayPort (DP) input. It also has a DP output for daisy-chaining. A USB port is provided for firmware updates. Use the remote or keypad to select the desired source.

How do I adjust the OSD settings?

Press the 'MENU/EXIT' button on the keypad or remote to display the OSD menu. Use the directional buttons to navigate and adjust settings like Brightness, Contrast, Color Temperature, and more. Press 'ENTER' to confirm and 'EXIT' to close.

What should I do if the screen does not display any image?

First, ensure the power cable is properly connected and the monitor is turned on. Then, verify that the correct input source is selected (e.g., HDMI, DVI). If using a PC, press the 'AUTO' key to auto-adjust the VGA signal. If the problem persists, contact a service center.

Can I control the monitor remotely?

Yes, the monitor comes with a remote controller that allows you to power on/off, mute, select inputs, adjust color temperature, and activate PIP mode. For advanced control, use the RS-232 interface with a PC running the R4N Commander protocol.

Is wall mounting supported?

Yes, the monitor can be mounted using the joint brackets supplied. Ensure the wall is stable and the mounting area allows proper ventilation. For video wall installations, contact a professional installer.

What is the warranty coverage?

The product carries a limited warranty from the ship date against defects in materials and workmanship. Improper installation or damage from mounts, adapters, or personal injury is not covered. Contact your dealer for detailed terms.

How do I update the firmware via USB?

Download the latest firmware from the manufacturer's website. Save it to a USB drive and insert it into the USB port labeled 'FW Update'. Use the OSD menu to initiate the update. Do not unplug the monitor during the process.

How can I control the monitor via RS-232?

Connect a PC to the RS-232 input using a D-Sub 9-pin cable. Use the R4N Commander protocol (VWCP) with commands like 'PWR' for power, 'MIN' for source change, and 'RML' for remote lock. The protocol uses 13-byte packets with STX (0x0f) and ETX (0x0d). Refer to the command list in the manual for details.

6. R4N COMMANDER (Video Wall Communication Protocol)

This document defines all the command and messages exchanged between the Master (a PC or the other controller) and the Slave (the displays). It also describes the ways to send or read the commands or the messages.

6.1 Protocol definition

VWCP stands for "Video Wall Communication Protocol". The protocol is specifically designed to allow data communication in half duplex multi-point environments, but it can also be used for full duplex point-to-point RS-232C communication.

6.2 Communication characteristics

A half-duplex communication is implemented starting from the concept of a master-slave structure, where the display is supposed to be the slave. The first action is always taken by the master, which can be either a PC or any controlling device (acting as server) interfaced to the monitor. After sending a command or a request in the appropriate format the master receives from the slave an acknowledgement, which tells the transmitter whether the command is not valid (or not executable, anyway) or it is accepted. In case of a request, the requested information is sent back and it becomes the acknowledgement by itself.

6.5 Transmission Formats

This is the format that the computer will send to the display to execute commands. The format for this command transmission is as follows: \- Data Length: 13 byte Ex) 001PWRWOFF0 (Set ID: 1, "Power Off" Send)
