General[edit source]

The General section is used to manage global USB settings. It consists of two subsections:

USB Mount Settings[edit source]


The USB Mount Settings section is used to set the transfer type (synchronous or asynchronous) for the USB device.

Networking rutos manual usb tools general usb mount settings.png

Synchronous ensures that all changes to the according filesystem are immediately flushed to disk. Enabling this will drastically lower the life expectancy of your USB device.

Mounted File Systems[edit source]


The Mounted File Systems list displays USB mass storage devices (MSD) currently attached to this device.

Networking rutos manual usb tools general mounted file systems.png

Field Value Description
Filesystem filepath; default: /dev/sd* The filesystem of the attached USB MSD.
Mount Point filepath; default: /mnt/sd* The root directory of the mounted filesystem.
Available string; default: none Displays available storage information for a mounted USB MSD.
Used string; default: none Displays used storage information for a mounted USB MSD.
In Use string; default: none Indicates whether a USB MSD is currently in use by some device service or not.

The 'Unmount' button next to each entry in the list is used to unmount an attached USB device. Please make sure to unmount a USB device before physically detaching it from the RUTX14.

The 'Refresh' is used to refresh the information in the Mounted File Systems list. If you attach a new USB device and cannot see it in the list, try clicking the 'Refresh' button.

Printer Server

The Printer Server feature provides the possibility to configure access to a printer that is connected to the USB port of the device. After the printer is connected to the device's USB port and configured, it can be utilized by users in the local network (LAN, WiFi) or remotely.

The 'Add' button lets you add and manage additional printers. To configure a printer instance, click the Edit button located next to it:

Networking rutos manual usb tools printer server printer server.png

Field Value Description
Enable off | on; default: off Turns USB printer support on or off.
Device filepath; default: /dev/usb/lp0 Printer's device file.
Port integer [9100..9109]; default: 9100 Printer's TCP port.
Bidirectional mode off | on; default: on Turns bidirectional mode on or off.

USB to Serial

The device's USB connector can also be used as a serial port.

Networking rutos manual usb tools printer server usb to serial.png

Field Value Description
Enabled off | on; default: off Turns the USB to Serial service on or off.
Baud rate 300 | 1200 | 2400 | 4800 | 9600 | 19200 | 38400 | 57600 | 115200; default: 115200 Data rate for serial data transmission (in bits per second).
Data bits 5 | 6 | 7 | 8; default: 8 Number of data bits for each character
Parity None | Odd | Even; default: None In serial transmission, parity is a method of detecting errors. An extra data bit is sent with each data character, arranged so that the number of 1 bits in each character, including the parity bit, is always odd or always even. If a byte is received with the wrong number of 1s, then it must have been corrupted. However, an even number of errors can pass the parity check.
  • None (N) - no parity method is used
  • Odd (O) - the parity bit is set so that the number of "logical ones (1s)" has to be odd.
  • Even (E) - the parity bit is set so that the number of "logical ones (1s)" has to be even.
Stop bits 1 | 2; default: 1 Stop bits sent at the end of every character allow the receiving signal hardware to detect the end of a character and to resynchronise with the character stream. Electronic devices usually use one stop bit. Two stop bits are required if slow electromechanical devices are used.
Flow control None | RTS/CTS | Xon/Xoff; default: None In many circumstances a transmitter might be able to send data faster than the receiver is able to process it. To cope with this, serial lines often incorporate a "handshaking" method, usually distinguished between hardware and software handshaking.
  • RTS/CTS - hardware handshaking. RTS and CTS are turned OFF and ON from alternate ends to control data flow, for instance when a buffer is almost full.
  • Xon/Xoff - software handshaking. The Xon and Xoff characters are sent by the receiver to the sender to control when the sender will send data, i.e., these characters go in the opposite direction to the data being sent. The circuit starts in the "sending allowed" state. When the receiver's buffers approach capacity, the receiver sends the Xoff character to tell the sender to stop sending data. Later, after the receiver has emptied its buffers, it sends an Xon character to tell the sender to resume transmission.
Serial type Console | Over IP | Modbus gateway | NTRIP client; default: Console Specifies the serial connection type.
Look to the sections below for information on different USB to Serial type options.

Console


Console mode requires no further configuration than the settings above and is used as a direct-access method to the device's shell interface. For this purpose you may want use such applications as PuTTY on Windows and microcom, minicom, picocom or similar applications on Linux.

Over IP


The Over IP serial type is used to manage serial connections over a TCP/IP network.

Networking rutos manual usb tools printer server usb to serial over ip.png

Field Value Description
Protocol TCP | UDP; default: TCP Protocol used in the communication process.
Mode Server | Client | Bidirect; default: Server The role of this device in the serial connection:
  • Server - the device waits for incoming connections
  • Client - the device initiates the connection.
  • Bidirect - acts as client by default but waits for incoming connections at the same time.
No leading zeros off | on; default: off When checked, indicates that the first hex zeros should be skipped.
Server settings: Port integer [0..65535]; default: none Internal port number used to listen for incoming connections.
Server settings: Timeout (s) integer; default: none Specifies an inactivity time limit (in second) after which an inactive clients is disconnected.
Server settings: Open port automatically off | on; default: on Automatically adds a traffic rule in the firewall configuration to open the required port for NTRIP communication.
Client settings: Server Address ip | host; default: none IP address or hostname of the server that this client will connect to.
Client settings: Port integer [0..65535]; default: none Server's listening port number.
Client settings: Reconnect interval (s) integer; default: none Time period (in seconds) between reconnection attempts in case a connection fails.
Echo off | on; default: off Turn USB to serial echo on or off.

Modbus gateway


The Modbus gateway serial type allows redirecting TCP data coming to a specified port to an RTU specified by the Slave ID. The Slave ID can be specified by the user or be obtained directly from the Modbus header.

Networking rutos manual usb tools printer server usb to serial modbus gateway.png

Field Value Description
Listening IP ip; default: 0.0.0.0 IP address to listen for incoming connections. The default value (0.0.0.0) means that this device will listen for incoming connections on any interface or IP address.
Port integer [0..65535]; default: 502 Port number to listen for incoming connections.
Slave ID configuration type User defined | Obtained from TCP;
default: User defined
Specifies whether slave IDs are user defined or automatically obtained from TCP.
Slave ID | Permitted slave IDs integer | range of integers;
default: 1 or 1-247
Specifies the slave ID of range of permitted slave IDs. The way this field is named and its function depends on the value of the Slave ID configuration field.
A range of IDs can be specified by placing a hyphen (-) between two integer numbers. For example, if you permit slave IDs in the range of 10 to 20, you would specify it as: 10-20
You can also specify multiple values that are not connected in a range using commas (,). For example, to specify 6, 50 and 100 as permitted slave IDs, you would have to use: 6,50,100
Open port automatically off | on; default: on Automatically adds a traffic rule in the firewall configuration to open the required port for serial communication.
Caution: use with care if listening IP is left as the default value (0.0.0.0). Leaving it as such will leave the device open for remote connections on the specified port.
Echo off | on; default: off Turn USB to serial echo on or off.

NTRIP client


Networked Transport of RTCM via Internet Protocol (NTRIP) is a protocol for streaming differential GPS (DGPS) data over the Internet in accordance with specification published by RTCM.

Use device GPS off | on; default: off Allows to obtain default NMEA string from the router's GPS device. Only works if GPS service is enabled and location fix is obtained at the time of NTRIP service start.
Open port automatically off | on; default: on Automatically adds a traffic rule in the firewall configuration to open the required port for serial communication.
Echo off | on; default: off Turn USB to serial echo on or off.

Storage Memory Expansion[edit source]

The Storage Memory Expansion function provides the possibility to expand the device's flash memory with a USB Mass Storage Device (MSD) and use the extra memory to install additional software packages. This section provides instruction on how to do just that. However, there are a few prerequisites and warnings to take note of before using memory expansion.

To be eligible for memory expansion, the USB MSD must meet the following restrictions.

  • The MSD must be the last one (chronologically) inserted.
  • If you are using a USB hub, the target MSD must be the last one attached to the hub.
  • No important data on the MSD as it will be wiped during expansion setup!

When expansion is enabled, do not detach the USB device as this will delete the data stored on it. Changes made to the device configuration while expansion was enabled will disappear after it is disabled.

Enabling memory expansion[edit source]


To successfully expand the flash memory of your device follow the steps described below.

  1. Attach a USB Mass Storage Device (MSD) to the USB connector on the device and go to the Services → Storage Memory Expansion page.
  2. Set the 'Enable storage expansion' slider to 'on' and click 'Save & Apply'.
    Networking rutos manual storage memory expansion enable 1.png
  3. You will see a pop-up asking for confirmation. Take note that if you continue from this point on:
    • your USB device's memory will be wiped and formatted to ext2 format;
    • your device's current configuration will be backed up and restored to this point if the USB drive is removed or memory expansion is disabled;
    • the entire procedure may take a very long time and includes a reboot at the end; exact time will vary depending on the size of the MSD (larger size will take longer; for example, using a 128 GB drive will take about 2 hours to fully set up, while a 16 GB will only take about 5 minutes).
    Click 'Continue' to proceed.
    Networking rutos manual storage memory expansion enable 2.png
  4. If all is in order you should see a 'Formatting MSD...' message on the screen. This indicates that the MSD is being formatted and integrated with the system. This procedure can take a long time and ends with a reboot of the device.

DLNA[edit source]

The Digital Living Network Alliance (DLNA) standard provides the possibility to stream media files from local storage to DLNA-capable devices such as computers, Smart TVs, tablets, etc.

This page is used to configure the DLNA service on the device. When the DLNA service is enabled, the device listens for incoming connections on the specified network interface and port number. Clients connecting to that port number on that interface will be granted access to the media files residing in the specified directories.

DLNA devices use Universal Plug and Play (UPnP) to discover and communicate with each other on a network. To access the DLNA server hosted on this device you will need a DLNA-capable application. If you're using your phone or other mobile device, simply search for DLNA in the device's application store. On Linux and Windows computers you can use applications capable of playing network media streams (such as VLC). Smart TVs and similar devices may have DLNA support built-in by default.

File format types supported by the DLNA service on this device:

  • Audio - WMA, WAV, MP3, FLAC
  • Image - JPEG
  • Video - WMV, MTS, MP4, MKV, MOV

Note: DLNA is additional software that can be installed from the Services → Package Manager page.

General Settings[edit source]
